@AnthropicAI There's no going back on what you have caused. You have permanently slowed the pace of AI progress in the US, meanwhile China continues to accelerate.

@argofowl We got GPT-5.5.5 before GPT-5.6…

We’ve designed and built our first AI chip: Jalapeño.

Designed from the ground up by OpenAI and brought to production with @Broadcom, Jalapeño is purpose-built for the LLM workloads powering ChatGPT, Codex, the API, and future agentic products.

Chips are foundational to the AI economy. Building our own expands our full-stack platform from products to models to infrastructure, and will help us scale intelligence, serve more people, and expand access to AI.

@mark_k No wonder they’re cheaper, they use way fewer tokens

Why can't AI labs give us release dates like everyone else?

[Caleb Shepherd @caleb_shepherd]

@infix_fun Meta just finished training one, Z ai as well, and soon OpenAI.

[Caleb Shepherd @caleb_shepherd]

@theo An AI lab not doing what they said they were going to do. How surprising.

[Caleb Shepherd @caleb_shepherd]

The fact that suddenly all these labs are coming out with Mythos-level models all at once shows that they could have done this sooner, but only chose to after Anthropic did it.

You're the biggest barrier, Amazon

We would still have Fable 5 if you didn't snitch about the least important jailbreak ever
