Anthropic releases Opus 5.5 with lower prices and higher limits

Claude users get two distinct changes: lower metered prices and more room within subscriptions. Anthropic is raising five-hour limits on Pro, Max, Team and seat-based Enterprise plans, and giving subscribers a usage-limit reset they can save for later.

Standard pricing is $4 per million input tokens and $20 per million output tokens, both 20% below Opus 5. Cache reads fall 60% to $0.20 per million tokens, a larger reduction for applications that repeatedly reuse stored context.

The bill depends on the workload

Anthropic's claimed 40% saving combines lower prices with fewer tokens used per task in its tests at default settings. That is a workload estimate, not a universal discount. The company also reports output generation more than 30% faster than Opus 5.

Fast mode in Claude Code and the Claude Platform costs $8 per million input tokens and $40 per million output tokens, with Anthropic claiming up to 2.5 times the speed.

Anthropic says external evaluators including METR and Frontier Design tested the model before release. It reports stronger prompt-injection defences, rather than immunity. Vetted organisations can apply for biology research access through its Life Sciences Verification Program; expanded cybersecurity verification access is planned.
