Claude Opus 5 Is Now Available

Anthropic released Claude Opus 5 today. It is now the flagship Anthropic model in AI Data Stream. Opus 4.8 remains available as the previous generation, so you can compare the two on your own analytics before switching.

Pricing

Anthropic prices Opus 5 the same as Opus 4.8 on the standard API we use:

• Input: $5 per million tokens
• Output: $25 per million tokens

Because the price is unchanged, moving to Opus 5 is a straight upgrade for most workloads.

What’s New

Anthropic reports large gains across the board, and the improvements most relevant to analytics work stand out: 9 percentage points higher accuracy on financial modeling with 60% less processing time, and notably stronger statistical rigor — Anthropic describes it as behaving like a “careful scientist”, cross-validating results before reporting them. It is also better at finding the root cause of a problem rather than just describing the symptom, which is exactly what you want when asking why your traffic changed. See Anthropic’s announcement for the full details.

Opus 4.7 Has Been Retired

We have removed Opus 4.7 from the model picker. If it was your default, you will move to Opus 5 automatically the next time you start a conversation — no action needed. Opus 4.8 is still available if you prefer to stay on the previous generation.

Effort Levels

Opus 5 supports the full effort scale: low, medium, high, xhigh, max. The same scale is available on Opus 4.8.
