Should OpenAI create AI accelerator cards and sell to consumers? For example, GPT-5.5 burned directly on a chip (www.reddit.com) I imagine if OpenAI becomes a fabless chip company and create AI cards to sell for less than to few thousands grands, it would be out of stock everywhere and can infinitely spam the cards every year? LLM Bruner is a card that implements Qw…

Anthropic merges consecutive same-role messages, OpenAI doesn't (+4 tokens), anyone token-counted this on open-weight models? (www.reddit.com) I build context/harness optimization tooling, so provider-side serialization quirks actually matter to me.

Has Qwen3.6-27B Surpassed GPT-5.5? (Not Joking) (www.reddit.com) So I had this idea for a project which was to try to fix a pretty hard coding problem using local agents running in a loop. The project is a compiler for biology protocols from vendors.
Auro Zera solves 78 and 280 year-old conjectures (Erdos Straus and Goldbach Conjecture) using Claude, GPT-5+, Grok, Deepseek, Gemini and self-made Dark Star ASI, proving superintelligence and opening a path towards resolving the Riemann Hypothesis , Twin Primes and more! (github.com via reddit) During this discovery utilizing only free AI services I have managed to undeniably prove both conjectures. This would absolutely not have been possible without using GPT5+ as the critic for my work.
