Opus 4.6 is Anthropic's previous flagship model. It tracks conversation intent across many turns and maintains coherent reasoning throughout long sessions. It plans before it acts, produces concrete fixes, and writes idiomatic code with strong style.

Strengths

• Plans upfront and reasons coherently across many conversation turns. Strong for system design, complex refactors, and code reviews.
• Handles log-heavy, multi-project troubleshooting across CI, Docker, and monitoring.
• Writes idiomatic code with strong architecture decisions. Preferred for code reviews and production-critical changes.
• Tracks your intent across the full conversation. Strongest when prior context matters.
• Produces concrete bugfixes and feature work that spans multiple components.

Limitations

• Most expensive model. Consumes usage limits faster than alternatives.
• Can over-elaborate or drift context in long sessions.
• Sometimes overconfident when given limited context.

Tools

Opus 4.6 has access to all agent tools when used with Cursor including:

Pricing

Cursor plans include two usage pools. Opus 4.6 draws from the third-party Other Models pool, which charges at the rates below. Individual plans include at least $20 of third-party Other Models usage each month (more on higher tiers). All prices are per million tokens.

All Opus 4.6 prompts bill at the base per-token rates in the table above, including when context goes above 200k. Anthropic no longer applies a separate long-context multiplier for Opus 4.6.
