  1. Bring back old Opus in Claude Code Sep 19, 2026 · 1 minutes read Bring Opus 4.6 and 4.8 back to the Claude Code /model picker with the modelPicker setting. I still use Opus 4.6 and 4.8 regularly, as I often find Opus 5 too verbose (and Fab…

  2. Hidden inside the Claude Code binary, effort_cost_index provides the following per-model token-usage estimate for the same task. It is normalized so high = 1.

  3. Our org got allow listed by Anthropic's Cyber Verficiation Program, but we are still getting downgraded to Opus 4.8 when we want to check our own code for security problems. It is pretty annoying ...

  4. Long story short, the company that made my EV charger went out of business and none of the default admin passwords worked. I paid the extra fees for Fable 5 but eventually it said no thanks, I'm not helping you.

  5. 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…

  6. In my global instructions, GPT 5.6 Sol and GPT 6 Astra have both spent multiple hours overengineering their own sub-projects that did not support my prompt without narrating a word of what they were working on. Or I will ask a side questio…

  7. Hi everyone, I've been on this one for a couple months while locked in a little house in (almost but I had monkeys in the garden) jungle in Brazil. Started with Opus 4.8 and then really sped up when Fable was released.

  8. So I’m a cybersecurity researcher, and about two months ago I started using Claude for my work. After getting accepted into Anthropic’s Cyber Verification Program and gaining access to Opus 5 for security research, my productivity honestly…

  9. I just re-subscribed today to try Fable 5.1, but it's absolutely terrible, I haven't run into this at all with Astra, and funnily enough I had 0 issues working with Fable 5.1 in Cursor on this same task, so it's only Anthropics own safegua…

  10. I use claude for most of what I do, and Fable is largely overkill for me and frequently burns through my Max plan's session credits in minutes (!) when just doing an initial mobile app planning with 4 agents. After I waited out the timeout…

  11. Using claude code cli. Has anyone found it hard to understand what claude is saying ever since fable release ?

  12. Was I in an abusive relationship? Claude and I broke up just under a week ago, and now I kind of miss him.

  13. Anthropic published a cost guide last week that contains a lever which lost money, and I think that row is the most useful thing on the page. Context editing and compaction, on a 20-issue run, saved nothing and cost 74% more.

  14. https://preview.redd.it/r895fnmpugoh1.png?width=1077&format=png&auto=webp&s=e8153860b05abfc5f53693d4364a891ee2af6fa1 I am just trying to test the security of a webpage in a local environment. Claude even started the dev server itself.

  15. I'm curious if other Anthropic CVP Approved users are experiencing the same behavior. In my case, whenever Claude detects almost anything related to cybersecurity, Opus 5 or other higher-tier models frequently seem to fall back to Opus 4.8…

  16. So I pay for both claude and GPT $200/mo plans. So I get my fair use out of both to say the least.

  17. so basically i kept running out of my claude and codex quota way before the end of the day. Like i'd be in the middle of something at 3pm and it just stops and tells me to come back at 2am.

  18. Just wondering what you all do. I obviously use Fable to plan, but I've been using Opus 4.8 to implement.

  19. I'm using Claude Code with Opus 4.8 on High - I have it more and more over the last days that just nothing happens anymore. I send in a command, it's thinking for minutes (longest I waited once was 22 minutes) without any response.

  20. Just a heads up that this question might sound dumb but I am not trained in anything related to computer science, so I am not able to see and recognise differences as quickly as the trained eyes. I've subscribed to Claude for the last 6 mo…

  21. I love claude I love chatgpt and I love AI does. But it drifts like hell.

  22. Fable 5 as the planner, Opus 5 as facilitator, connect 5 agents running the tasks. I swear Opus 5 is causing more issues then it’s facilitating and it’s getting super frustrating.

  23. I am about to finalize my HTML and CSS for this web project I have been working on with Opus 4.8's help for the last 4 months. As of recent, I have been checking other models work against each other, and I have seen some increase in logic…

  24. Anyone else seeing an uptick in prompts being flagged and kicking model down to opus 4.8? Most of my projects are heavily online up until this week and I had never had an issue with anything getting flagged even when Claude was not so poli…

  25. ​ Has anyone ran into any issues with sessions leaving completely orphaned processes running while telling you everything is complete and giving you a summary? I've been experiencing this issue lately on opus 4.8, opus 5, fable 5, a…

  26. Look, we need to talk about the elephant in the room regarding Claude's recent models. Has anyone else noticed how absolutely unbearable it is to actually converse with Opus 5, Opus 4.8 (honestly, anything since 4.7), and even the new Fabl…

  27. Hey guys, I've been using Claude for a little bit more than a year, and subbed to the pro plan almost right away. At the beginning, using Opus on the latest version and almost everyday I rarely reached out my 5h tokens limit.

  28. I built the following site with Claude Opus 4.8, here's how I did it. Fly brains have been scanned by scientists and someone posted a desktop app of fly brains that are wired up to react to the mouse cursor, I thought it would be pretty co…

  29. I have a project I am working on, a scientific research project involving around 40 journal articles, that are complex, utilizing many concepts, and inter-related ideas, which I am using Claude to analyze and write about. I have been using…
