Claude Mythos Preview is Anthropic's most capable model but is gated to ~40 pilot orgs via Project Glasswing for cybersecurity use (AWS, Apple, Cisco, CrowdStrike, Google, JPMorgan, Linux Foundation, Microsoft, Nvidia, Palo Alto Networks among them). It is NOT in consumer Pro/Max tiers -- those get Opus 4.7, which Anthropic concedes trails Mythos on cyber tasks. Anthropic has stated Mythos Preview will NOT be made generally available in the near term

Opus 4.7 uses an updated tokenizer -- input tokens may increase roughly 1.0-1.35x depending on content type, slightly raising per-request cost even though the published per-token rate is unchanged
