Get ready, friends. Anthropic appears to be preparing the release of its Mythos-level model.
Pricing: $16 per 1M input tokens / $80 per 1M output tokens.
The release is likely very close, possibly even in the same week as GPT-5.6. Competition is heating up again.
Gemini 3.5 Pro is about to face serious pressure. It better be a banger.
