haider1 · x · 2026-08-25
The author expresses concern that public models are falling further behind internal ones. Noting that Astra is already delayed (it was supposed to release 2 weeks ago) and Anthropic is deliberately keeping Mythos 5.1/2 internal. By the time these models reach the public, Mythos 3 and Astra.x will likely already be trained.
