OpenAI gets a $500bn Stargate launch at the White House.
Anthropic gets its flagship models taken offline.
OpenAI still doesn't have a Mythos competitor.
The conflict-of-interest questions write themselves.
The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

I asked Codex to look through my Windows system logs and report back on anything it could fix.
It actually fixed a bunch of annoying Windows stuff Iβd just learned to live with and never got round to sorting.
If youβre on Windows, try it.
Each time we release a model, we run the same test: give it code that trains a small AI model, ask the new model to speed it up. It takes a skilled human 4-8 hours to reach 4x faster.
In May 2024, Claude Opus 4 averaged a ~3x speedup. This April, Mythos Preview achieved ~52x.
nothing like switching to claude for a few days to try out a new model and going back to codex xhigh to remind you how much better 5.5 is right now
it's really not close
