Model overview
Top of Anthropic's published rates: claude-fable-5 bills $10 per million input tokens, $1 for cached input and $50 for output, double Opus 5 on all three lines and ten times Haiku 4.5. The capability record buys none of that gap — the same 1M-token context and the same reasoning, tool use and prompt caching every model on this provider lists. Mythos 5 carries an identical $10 / $1 / $50 card, and the single field separating the two is availability, this one being generally available on the Claude API. The decision against Opus 5 at $5 / $25 is therefore a straight doubling of cost, and the decision against its price twin is access rather than money.
