The lead
Anthropic ships Claude Opus 5, priced for volume rather than for a capability jump
Anthropic puts it close to Fable 5 on capability at about half the price. The practical read is that frontier quality per franc keeps falling, not that the model suddenly does something new.
Opus 5 landed on 24 July with a 1 million token context window, up to 128,000 tokens of output and a five level effort control, at unchanged pricing of 5 and 25 dollars per million tokens. The reported headline is efficiency: similar quality to Opus 4.8 on legal work while producing roughly a quarter fewer tokens at max reasoning.
KRALYSRerun one Katarina workflow on Opus 5 at a lower effort setting and log tokens and minutes before and after. If the token drop holds, the same monthly budget buys roughly a third more automated work.
