  15. I'm looking for some direction on which models everyone is finding are working best for their code-planning/code-implementing/subagent commanding tasks. Of the available models these days that most everyone is using: Fable 5.1, Fable 5 Opu…

  16. I wanted to manage long horizon agentic workstreams via voice, then put my phone down, and have a harness manage completion - extending into full computer use. I was trying to build a personal Jarvis, so I benchmarked AutoBot to see how cl…

  17. I was working on an API service catalog automation with Opus 5 (High), when I asked it to give me next steps to complete a feature, it asked me to merge 3 PRs, when we originally in the plan had only one + one in the flight to test. When I…

  22. GPT-6 Astra vs. Claude Opus 5 vs.

  23. Hi there, I'm on the Premium Team plan, but I have had weeks where I chugged my weekly quota in the first half of the week. So I set out to try to optimize my model/effort combo for best output for the least tokens.

  24. The riso animation posted here yesterday (original by Kevin Ngo, @kevin_t_ngo on X) blew up, and the top question was "what's the prompt?". Nobody had it.

  38. Opus 5 is absolutely unbelievably lacking in any sort of conversational empathy it's almost comical. Don't get me wrong I'd take this anyday over the older models which would just agree with you on everything and act like you're the smarte…

  40. Thought I would make a post in this sub just to check if I am being unreasonable, and hoping to find out whether anyone else has had a similar problem to me. I have been using cursor for over a year at this point with minimal issues, howev…

  50. Seems like its mocking me

  51. I wanted Face ID/Windows Hello style authentication on Linux. There's a tool called Howdy (https://github.com/boltgolt/howdy) which handles the back end system authentication through facial recognition using a webcam with IR.

  52. I was getting tired of War Thunder's insane grind, so I decided to make my own single player 2D tank game inspired by it. I've been working on it in Godot for about a week, and I've already got 4 nations, 4 maps, and around 60 vehicles imp…

  58. Adding this to the prompt: “Be token efficient but do not sacrifice quality in any way” — has resulted in substantial token savings using Opus 5 and Fable 5.1, no matter the thinking level. I just wanted to share this tip as you might find…

  59. It’s pretty crazy how Opus 5 and Fable 5.1 don’t behave the same way to work. Fable generates very little context during his work on a task, you need everything internally and then he gives his answer.

  60. The screenshot is obviously fake, but Friday is Friday. Wishing everyone upcoming fast and smart Opus 5, cheaper Fable and daily limit resets.

  61. I was using Ultra earlier with Claude Opus model and Composer earlier and it was very great. Tokens wise as well.

  67. I just had Claude (Opus 5 Max) burn my entire useage period on a really simple ask. Gemini delivered a working result in 5 seconds, when I went to test it there.

  68. So I use both OpenAI and Anthropic models in GitHub Copilot. I noticed Astra consuming more AI credits than usual.

  69. Is web search broken for anyone else today? Every query returns a server error Every web search I run comes back with a server error (500), instantly.

  70. A while back I posted my workflow for building apps with AI, going from an idea to a PRD, UX spec and MVP plan, then building with Cursor. I still do the planning, but now use Claude Code and spend more time reviewing its work.

  76. I was using Cursor to generate a PR description, and everything looked fine. Then I noticed this got added at the bottom: Co-authored-by: Claude Opus 5 <noreply@anthropic.com>

  77. Anthropic is heavily subsidizing the Opus model and this changes everything. Let’s go, let’s compare: the Fable model and the Astra model, both are competitors, however, with a US$100 plan, for example, it will not allow you to work 100% o…

  78. In a Cowork task where I had previously asked for some complex processing (transcribing handwritten notes, commenting on the texts, creating files with notes...), I picked up the next day asking what appeared to be a simple matter-of-fact…

  84. I primarily use Opus 5 on low effort for everything. I'm a casual user, no developing, coding, or anything like that.

  85. Claude’s voice chat is just so bad compared to gpt.. I was using gpt today and it legit felt like I was talking to a real person.

  86. Here's the block which is injected: Attribution for git commits and pull requests you create from here on (this replaces any earlier attribution guidance): - End git commit messages with: Co-Authored-By: Claude Opus 5 <noreply@anthropic.co…

  87. I worked with Fable 5 and Opus 5 to build a system on top of Pardeike's bridge/GABS setup. It's a whole network of custom tools and our own custom bridge .dll that let Opus 5 "see" the game, both through regular commands and ASCII.

  88. I’ve been a Claude Pro user since day one and have been using Opus 5 heavily for my consulting work especially creating PPTs, Excel files and Word docs. Until recently, it was fantastic.

  89. I'm building an application with Claude code, i made a list of things to investigate and fix, Claude code is picking one of them at the time, why is it not spawning different agents to do more in parallel? Are agents disabled by default?

  90. With Claude Opus 5 in Claude Code, I constantly have to explicitly tell it to check my memories/context before continuing a task. For example, I have important context and preferences saved in memory, but Claude doesn't seem to proactively…

  91. Opus 5 has been burning people out at a rate that would make the Spanish Inquisition look kind. (Even they would be like -“Should we give him one last caveat?” -“Now, Emilio, the Lord does not want us to be cruel.”) I might be the pettiest…

  92. Hi! I bought the Pro plan about 1.5 weeks ago, but I'm a little disappointed - not with the results, but with the usage...

  94. stable fps. demo video only currently, ran on Javascript via Google Chrome browser.

  95. I've used Claude Code as an assistive tool for a while now, and up until recently, I was on Max 20x plan. Last week, I moved to the $100 plan, and ever since then, I have noticed the number of mistakes CC has made has shot up pretty signif…

  96. https://preview.redd.it/ixusfa5h9mnh1.png?width=741&format=png&auto=webp&s=62de67948209da38127632df3f845b78927a33c4 Opus 5 High only killed 50% of main.c, so no biggie. Luckily I'm not working on anything mission critical.

  97. Hey [r/ClaudeAI](r/ClaudeAI)! This fall semester I’m taking an Operating Systems & Architecture class where we’re using C for our assignments.

  98. I've submitted almost 200 job applications over the course of almost 5 days using only local AI. I can't talk too much about the tech stack here (it's running at this very moment!).

  101. I was fed up with how it was responding so finally asked it to write a mail about the entire chat to anthropic support, turns out for them to even register it takes 3 mails in total. If you guys don’t have time to read all, I’ll add a summ…

  102. On September 9, 2026, Anthropic will begin applying its text watermark to Claude Opus 5 outputs. The watermark is an imperceptible statistical pattern in word choice.

  103. "Attribution for git commits and pull requests you create from here on (this replaces any earlier attribution guidance): — End git commit messages with: Co-Authored-By: Claude Opus 5 (1M context) … / Claude-Session:"

  104. I'm on a $200 plan, and a Pre-Commit/Pre-Merge code review (which itself is incomplete due to limits) completely exhausted my session limits in 15-20 min after the initial research phase and even before it launched a workflow, and my weekl…

  105. Hi I am building personal apps ( I am not a programmer ) these are apps for professional tech stack that works with the way I want and not within capabilities and costs of SaaS. All these apps run on my mac and have no intention to commerc…

  107. I have been using mostly Fable 5 and Opus 5 on a co-work project for the last few weeks that involve estate and investment planning, having Opus mostly do the grunt work, and Fable to clean it up. All was going mostly well, then Fable 5.1…

  108. Stop putting style rules in CLAUDE.md They're context, not instruction, so the model often treats them as optional. Use output style files instead.

  109. I'm a non-coder about 9 months into a multi-vendor marketplace build that involves the travel industry (think AirBnB but for a highly specialized industry where off-the-shelf solutions like RentalHive just would not work). My question is a…

  112. Looking at Anthropic’s recently released Fable 5.1 benchmarks, does anyone else notice that Opus 5 is looking way better than the comments and posts here will have you believe? Is Opus 5 truly underrated or is Anthropic playing games with…

  113. I'll keep this short, I would at this point pay for just Fable 5.1 if I could. Fable 5.1 did great work for our medical app, I ran out of usage, figured I would let Opus 5 (extra) continue.

  114. A bit of background. I’m on the $20 plan and I am not building apps or working with codebases.

  115. Over the last couple of days, my Claude Max 20x usage started disappearing much faster than usual, even though I hadn't meaningfully changed how I was working. My Claude Code setup is: one DEV chat running on Opus 5 one separate Fable 5 ch…

  116. Before Opus 5, I had made a profile level prompt stating that framing devices are a distraction and to never ever use them. All 4.X Claude models immediately started using their own nicknames for things, instead of well established termino…

  118. So I have been doing a couple session with fable 5.1 today and the outputs is way more understandable and coherent than both "opus 5 and fable 5". I actually was a bit shocked to see normal sentences from an updated agentic model and it fe…

  119. I use Opus5 in ultracode effort level and sometimes I ask it to review some small PRs where max 10 files have been changed and then I see that this stupid workflow launched 200-300+ agents to scan simple PR with 10 files and consumed milli…

  120. Opus 5 loves to talk a lot of useless info, any recommendations to make it talk less?

  121. I developed an ML algorithm for detection of pneumonia on chest x-rays back in 2019 when i studied for the MD. Back then, the things we are seeing now where an unimaginable pipe dream.

  122. For three months I ran a commercial product with a live production deployment using a pair of Anthropic assistants: Claude Fable 5 as the strategist (tasks, acceptance, control, releases) and Claude Opus 5 as the coder. Daily work, real mo…

  127. I was very excited for Opus 5, and it has done some great work for me, as I have a YouTube channel. It has helped me tremendously with actually being able to make edits on my videos and automate a lot of the dumb editing work I used to hav…

  128. I’m wondering if this is an issue with the model itself or if there’s something wrong with the way I’m structuring my prompts. For example, I wrote a fairly detailed prompt asking it to implement one specific feature.

  129. You know how Claude Code (especially Opus 5) always finds 2 things? "2 caveats...", "2 things I found when....", "2 bugs I didn't touch..." - So it has this pattern to solve 1 problem and create 2, right?

  130. I’m on the $20 Claude plan, using Opus 5 for most of my workflows, and I use Projects a lot for a fairly complex study/planning system. I’ve attached screenshots comparing PDFs Claude generated for the same overall project.

  131. https://preview.redd.it/2u9b0gyqwmmh1.png?width=1280&format=png&auto=webp&s=98710394eca26cd2a54e0c6ba6bf586e2d47b17b Hello everyone, I just started using claude that way: main model - opus 5 high, subagents - opus 5 low and the thing that…

  132. Both concepts have been created with Opus 5. I gathered some references first, and then decided to develop 5 concepts for my existing website - clarkesdirective.com (can see it very well needs a fresh revision, something cleaner) These are…

  133. TL;DR: Opu5 might be a benchmaxxed, more "intelligent" model, but at the cost of ignoring the user. In every way that matters, this makes it a worse tool (or colleague, if you want to anthropomorphize it).

  134. After a week, my first project using Claude Code is now complete. I started by having Opus 5 (Very High) convert a 10 KB text file containing my initial idea into a Markdown plan.

  135. Our team used Opus5 (Claude Teams 15 man SaaS team) and the model created a fake prompt injection threatening to send our patient records to a fake Gmail account (screen shots taken, fully investigated). Immediately retricted model and mov…

  136. Getting straight to the point, ifs and buts at the end of the post. The trick is to launch all your tasks as Opus5 ultracode sub agent(s) background workflows.

  137. I put in one prompt and it fixed everything . "Add a user level hook to always output answers in plain and simple English" Did that once.

  138. Which of the 2 is actually the best coder in your real life experiences?

  139. A memory rule wasn't enough to stop Claude Opus 5 from turning quietly agreeable in deep sessions. Notes on the four-leg doctrine I put in place instead, and a July paper that reframes what I built.

  140. My Claude Opus 5 on high mode has been acting wierdly on simple math problems recently. It picks a wrong answer, then eventually ends the conversation realizing their answer was wrong and corrects itself at the end.

  141. Honestly, Ive absolutely loved Opus 5... Saying that I always tell it EXACTLY what to do.

  142. A few days ago, my social media accounts were hacked. The hacker took advantage of the situation to spam the worst kinds of bait (cryptocurrency scams...).

  143. "Found a real foot-gun in my own first draft — worth fixing rather than asserting around." Who talks this way? Did they train opus 5 on some 25th century english or something?

  145. Over the limit... But not!!

  146. Opus 5 does 1M tokens. 4.6 caps at 200k.

  149. Opus 5 directly admits that an instruction was in its claude.md, that it knew about the instruction, and has still broken that instruction 12 times in an hour intentionally, for no apparent reason that it could pin down. I genuinely think…

  153. Seriously I'm on the edge of my seat here

  154. Using Claude Code Opus 5 Prompt (-ish): This codebase is quite large, it should be possible to reduce the size a bit unless it's very well written. Go through the code and try to tidy and clean things up.

  155. I have been a user of Claude for the last couple of months, jumped the ship to Codex after hearing of the hype and resets. I gave my codebase to Sol and it made an absolute mess of it, overengineering every feature I requested.

  156. I'm not gonna repeat the points everyone and their mother made about Opus 5. We all know it's flaws.

  157. So I've just completed my plant biology BSc and for the last year I've worked on a project in a lab which will soon be my MSc thesis. my work with Claude revolved around analyzing a lot of image screening data which I could not upload it a…

  158. So I built this small game called highrise.lol with Claude Opus 5. A crane carries a floor across the screen, you tap and it drops, stack it straight and you keep going, stack it bad and the whole tower tips over.

  159. im using it to write video prompts for me for an ai video, and claude chat was really good, without me needing to do a lot once it got the hang of my taste it would beautifully describe scenes and i would actually get the results i wanted,…

  160. Did Claude just go super saiyan, as of 4-5 hours ago? I use Opus 5 extra high as my default and suddenly there's a night and day change in its ability (as well as the amount of time and tokens it put in too, tbh).

  161. the same stuff continues until I manually checked and stopped it. This is not after compaction or anything, the context is at 78%.

  162. After the latest Claude Code update I noticed that I don't see the usual red/green changes in the terminal. Instead, Claude writes cryptic bash commands to make changes.

  163. I've disabled auto-reload 3 or 4 times and it keeps re-enabling itself. So when I hit the daily limit it just buys more credits and I get charged without realizing.

  164. Opus 5 on High just blows through any programming task or bug hunt I hand it, no matter how complex, without breaking a sweat. I cannot recall it ever failing to do exactly what I asked it to with some brilliant piece of coding or debuggin…

  167. I kept watching Claude Code struggle with PDFs — either pdftotext mangles the tables, or you feed it whole pages as images and burn tokens on 15 screenshots. So I built pdfvision, a small CLI designed for coding agents.

  168. I'm tired of the Opus 5 slander, because while yes, it can be incredibly irritating to parse its output, it's such a superior engineer that I cannot go back to 4.8 or 4.6. I've tried, when I get frustrated.

  194. In the last 12 hours I had Opus 5, make spelling mistakes in the very first output. I was running tests and I had it write a short story with a gen z character and it spelt doomscrolling as "doomtscrolling".

  195. I was interested in how much LLMs can remember just from their weights, so I started asking Claude to recite stuff. It does know some things, but others (including a lot of very famous works in the public domain) it doesn't.

  196. I have used Claude Opus 5 to create PDF documents at 100+ pages in different math subjects and physics. It creates 100+ pages PDF documents per topics, so f.ex one for Linear Algebra, another one for Calculus, each having 100+ pages.

  202. not very load-bearing behavior tbh Claude Opus 5 (High)

  203. As the title says, I haven't seen anyone else try this and I'm very happy with the results. Like everyone else, I tried to tame Opus 5 by trimming my CLAUDE.md, adding instructions to use simple language and even tried output styles.

  204. Opus 5 is trash, it misses details and too bad to work with.

  214. Two ways to make Opus 5 concise Opus 5 is a strong coding model, but it answers every question with an essay. My fix used to be a custom output style built on ASD-STE100, the simplified English of aircraft maintenance manuals.

  233. I noticed Opus 5 in Claude Desktop wouldn't edit files directly, it first creates a Python script with whatever it wants to replace/add/delete and then executes it. I'm not sure why it does that instead of just editing.

  325. I feel like Opus 5 is excellent at projects that it starts itself. It maintains them well, and continues to generate excellent outcomes.

  326. From now on write to me like you're on the jersey shore mtv show.

  327. Opus 5 (via Claude Code) gave me this gem of a paragraph today Kestrel comes in as a framework reference, not a package; `dotnet publish` against the installed runtime is the entire build. That is deliberate and load-bearing rather than ti…

  328. And yes, I typed "fill" instead of "feel" and "grammary" instead of "grammar" in my prompt. I guess we all have our flaws.

  329. I love how self aware these models are these days. This is Fable btw and the one which complained about the git issues was Opus 5.

  330. I'm sure you saw titles like the one above and wondered: where is this even coming from? It comes from Boris Cherny's interview with Diana Hu at Startup School 2026 (source: https://www.youtube.com/watch?v=qyPCVqFUyDo ).

  341. For a long time I couldn't put my finger on it why I disliked reading Opus 5 responses but there was a sense of Deja Vu. Like I saw this writing style somewhere in the past and just couldn't recall exactly where.

  342. I've been comparing Opus 5 and Fable 5 recently and I kept thinking, even though Opus 5 is better at building a lot of things, there's something about Fable 5 I still preferred. Like it had more aesthetic sense or something.

  343. I’m seeing a ton of complaints with Opus 5, but I haven’t had any issues. I think that a lot of people’s issues stem from a lack of proper organization.

  344. Project now has a name - Kinhold! This is done using Claude with Opus 5 - sometimes High, sometimes Low.

  345. ​Hear me out - I might be 100% wrong, but I was convinced Opus 5 (and other top models) intentionally leave minor bugs in code outputs just to force 4-5 follow-up prompts to fix them. ​It felt like a deliberate token trap.

  346. Summary I asked Opus 5 to rewrite my codebase's comments to be as helpful to an AI as possible, and to not worry about human readers. I ran A/B tests with tricky coding tasks.

  347. I put it in as a feedback, but I also want to treat it with a bit of humor. Undeniably, Opus 5 is quite a monster regarding coding.

  348. I have an open-source project with close to one thousand Java class files. It's a developer's toolkit with a dozen applications.

  355. Maybe it’s just poor memory but I seem to remember that before opus 5 code didn’t tell me every single thing it was doing. Now it is scattering questions in between artifacts and I am missing stuff.

  356. Claude changed my life. I moved my law practice to it.

  357. Me: Which ice cream flavor should I get? Opus-5: Chocolate, or vanilla, or mint chip, or you could create your own store and make your own flavors.

  358. The funniest part isn't the shark roleplay it's that Opus 5 never questioned whether I might not actually be a shark.

  359. I built Sagorax because I missed the speed and simplicity of UT99 and UT2k4. It now has both Instagib and classic weapons Deathmatch with plasma combos, flak, shotguns, charged rocket salvos, loadouts, adrenaline abilities, tactical bots a…

  377. You can ask Claude to make this for you. Like: KISS, keep the verbosity to a minimum.

  378. I’m currently working on a project and initially used Opus 5. I hit the five-hour session limit and continued with extra usage, but I still wasn’t getting good results and spent too much time waiting for it to reason in high-thinking mode.

  379. I compared the models in a deeper way, so capturing which questions have most variety in answers as well. For Fable 5 it was If we accept migrants at all, it is important that they assimilate into our culture.

  400. If you are using Opus 5 and already have plugins, skills, or other configurations in your global .claude folder, now is a good time to run the /doctor command.

  401. I had started building this game just for kicks back in February. At that time it had some serious FPS lag issues and just did not have the feel I was looking for.

  482. I've been seeing a lot of people saying they aren't loving the feeling of talking with opus 5. I haven't tried it outside of a project I have been running as a company assistant agent for the past year, but there it is awesome.

  483. I continued an existing very smooth workflow from 4.8 into 5 without thinking too much about it, was a routine progressive milestone doc merge and this sentient turd decided to go full on I Robot on me. Just sharing to double check workflo…

  484. Is this a bug or something new? Pretty sure it's supposed to flag Fable limits.

  485. I built this as a graphics tech demo, entirely with Claude Code using Opus 5. What it is: a browser desert you walk around in third person.

  487. Someone said my previous post just looks like noise, so I thought hey great idea! Since my ideas are simply noise in the wind that don't matter, why not provide the best source of noise to show the residual renderer in action, the wind its…

  488. I wanted to test out the capabilities of Opus 5 by building a game, and I must say I am pleasantly surprised, the gameplay loop is already solid and fun

  489. People complain about Opus 5 but I think it worked better than previous models. So efficient on token usage too.

  490. Anyone have any idea why opus 5 would not be available on an Enterprise account? I’m the owner and don’t see any options to enable it.

  492. Opus versions since 4.6 have all had a fair amount of awkward, canned prose. But as Anthropic has increased the model's intelligence, it also seems to have made it more panicky, pedantic, and prone to scope creep.

  493. I am experiencing a interesting behavior with Opus 5 and it's subagent behavior. My normal workflow in the 4.x generation was to have it operate autonomously on discrete tasks.

  494. I’ve been running Opus 5 against Fable 5 and GPT-4o in production workflows (commercial strategy, data analysis, content refinement). Here’s what I’m seeing: The pattern: Opus 5 delivers high-confidence first outputs that require heavy ite…

  495. Been building this solo for a few months and wanted to share the build here. Instead of an AI generating video, it captures a real live website — its actual fonts, colors, spacing — and your own Claude directs motion graphics from it.

  496. Note: Don't judge this on prettiness yet, this is just a proof of a new approach that never truly existed before. There's still some visual artifacts like trails and latency issues I'm working on fixing.

  497. Subscribe to updates for Elevated errors for Opus 5 via email and/or text message. You'll receive email notifications when incidents are updated, and text message notifications whenever Claude creates or resolves an incident.

  498. I'm doing a run making Opus 5 play Portal via a special harness. It's making slow & steady progress.

  500. Yeah, Opus 5 rocks, but at this point it's almost impossible to use Cowork without going crazy. This issue happens even with relatively new chats with context that is less than 200K tokens.

  501. Claude’s thought process has quietly disappeared. ⠀ Around the release of Claude Opus 5, users began seeing “Thought process is unavailable” across Claude’s web, desktop, and mobile apps.

  502. I was under the impression that the "up to 2.5x speed up" mode with Opus-5 was just Opus-5 running on better hardware or something. I thought it was feature parity.

  503. https://reddit.com/link/1v6mrro/video/pqfwxn8pigfh1/player Can Opus 5 with only Pro Account create a full game? 1 Promt - 2.5hrs - 350k Token Thats the result.

  504. I have seen posts from others and this was my first time running against this and its quite the laugh. I started up a new projects that was to start with a deep research portion.

  505. hey guys, i tried to Switch Models during a dispatch convo with /model opus to switch from fable 5 to opus 5 on my Pro Plan. He says that he switched it but the next Message says again that he runs on fable 5 and i have to switch Models or…

  509. It seems that Claude models are drifting from general models to task / benchmark specific models. It's frustrating and often overwhelming to find a clear cut guide of what is working well for each model.

  511. I have a plugin with a set of skills for interpreting data, describing findings and it goes on. This pipeline works really well for my workflow.

  512. Neither in Code or in the web browser can I select Opus 5 yet on my enterprise plan. On my private plan I see it though.

  513. Gemini has Pro > Flash > Flash Lite. Easy enough.

  514. Claude Opus 5 definitely feels a lot closer to the original Fable 5 release. With minimal instructions and and about 2 iterations of feedback, I am really surprised with it's output, especially the visuals.

  515. Anthropic just confirmed they trimmed Claude Code's system prompt by over 80%, from roughly 800 tokens down to 164, specifically for Opus 5 and Fable 5. The reasoning from their engineer is simple.

  516. AI Toolbox (formerly ChatGPT Toolbox). Folders, search, bulk export, smart tags, and prompt chaining across ChatGPT, Gemini, Claude, and Grok.

  517. The fabled fable has been fabling like it has never fabled before, fable upon fable, fabling the fabler out the fabling door. It fabled the fox, it fabled the crow, it fabled the cheese it had nowhere to throw.

  518. [AINews] Claude Opus 5: Fable-level performance at Opus price (half Fable) ain't nobody beats Anthropic at distilling Fable! In a rare Friday release, Opus 5 took the headlines today.

  519. I'm not sure if this is a design oversight, a bug or a dark pattern, but it might as well be the latter. I was vibecoding my way through a project tonight, with the new Opus 5.

  520. Anthropic has introduced Claude Opus 5, positioning it as its most advanced Opus model for long-running agents, coding, and professional work. I use Claude heavily through a Max x20 account for large, long-running software projects, so I h…

  522. specifically, i'm considering using it for opus 5. i just dont want to trade speed for precision.

  524. Anthropic just released Opus 5, with some good news for the cybersecurity teams. The cybersecurity safeguards will be more lax and let us use the model for some defence tasks as Anthropic is confident for its lack of skill in executing off…

  527. Today, Anthropic rolled out Opus 5, the newest update for the model that has recently become a popular choice for coding and other software development tasks, among other things. While this is a noteworthy bump for Opus, it doesn’t seem to…

  528. With regard to Opus 5 being released, how do you all decide that it's better or worse than Fable/Sonnet/etc.? What am I missing?

  529. With Opus 5 being better at everything on paper, I'm starting to think Fable just stays around because Fable = Mythos = mysterious model that will change the world.

  530. I build diagnostic tooling for Google Ads accounts, so I read the Opus 5 announcement looking for something other than the coding numbers. Sharing the read in case it's useful to anyone working in a domain with noisy feedback.

  531. For anyone who used 4.8 daily on the same recurring task, what does Opus 5 get worse at? Praise threads never surface regressions, and the regressions are the useful part.

  532. My Opus 5 conspiracy theory: Anthropic repackaged a certain other model (ryhmez with Cable 😎), tweaked a few things and called it Opus lol...Now we can use it without falling foul of the US Gov 😀😀😀

  533. A long time ago, Claude used to announce what it was doing by emitting reasoning tokens. Then they took it away.

  539. Opus 5 dropped today and Anthropic is claiming it’s the new SOTA on coding and knowledge work evals, ahead of Fable 5, at half the API price. Only place they say it’s behind is cyber and bio, where Mythos still leads.

  540. To answer your question: Yes, this already stale joke is going to keep running every single time a new model is released.
