Anthropic upgrades Claude with new Opus 5 model, details here

Anthropic has released its latest AI model with Claude Opus 5. The new version arrives about two months after the previous Opus model upgrade, matching Anthropic’s previous upgrade cadence.

Anthropic currently offers a lot of AI models under the Claude umbrella.

The three main models are Haiku (smallest and cheapest), Sonnet (medium size and price), and Opus (largest and most expensive of the three).

Today’s release upgrades Claude’s Opus model from version 4.8 to version 5.

Anthropic describes Opus 5 as a “thoughtful and proactive model that comes close to the frontier intelligence of Claude Fable 5 at half the price.”

Fable 5 is the released version of Mythos with safeguards, which Anthropic originally held back due to its capabilities around cybersecurity. Fable 5 remains Anthropic’s most capable model.

Opus 5 is designed to be used every day: it works more efficiently than other models. It’s the new default model on Claude Max, and the strongest model on Claude Pro.

Anthropic points to two more releases today in addition to Claude Opus 5:

Anthropic says Claude Opus 5 is available today for every platform. Opus 5 is $5/million input token and $25/million output token, matching Opus 4.8 pricing.
