- Despite heavy talks in Washington, there is still no timeline: Anthropic says it has no news, and nobody knows whether or when the models will return.
- The fight hits a key business bet: Mythos was meant to lift revenue before a possible IPO, with input tokens reportedly priced at twice Opus 4.8.

## Nauti's Take

This is not a clean safety process; it is a case study in policy uncertainty. When a model can be tested, launched, monetized, and then abruptly frozen through an unclear government process, the result is less safety and more operational chaos. Anthropic does not look in control, but the bigger issue is in Washington: serious AI regulation needs clear thresholds, procedures, and authority. Otherwise every frontier release becomes a political bet.
