Anthropic ships Opus 5 — its fourth model in under two months

Anthropic released Opus 5, which the original piece describes as near-frontier in capability and priced identically to Opus 4.8 — the same $5/$25 per million token figures the previous model carried.

The shipping cadence is the story worth pausing on. Anthropic has put out four models in under two months, which compresses the usual 'release and stabilize' window into something much tighter than the industry norm.

Operationally, Opus 5 is already the default on the Max tier, so subscribers do not have to opt in to see the change. For anyone running agents or production prompts against the previous generation, this is a quiet upgrade moment.

The original coverage has the benchmarks and a comparison to the prior model. My read is that pricing parity is the more interesting signal than the benchmarks — Anthropic is choosing to compete on capability at the same dollar, not on a price war.
