- Opus 4.7 is the strongest generally available model for coding, enterprise workflows, and long-running agentic tasks, improving on ambiguity handling, bug finding, code review, context retention, and reasoning with less direction compared to Opus 4.6.
- Optimizing Opus 4.7 in Claude Code involves treating Claude like a capable engineer for delegation, with a default effort level of xhigh (between high and max) recommended for most agentic coding work, while effort levels (medium, low, high, max) offer trade-offs between intelligence, cost, and latency.
- Adaptive thinking replaces fixed thinking budgets, allowing Opus 4.7 to decide when to think more based on context, leading to faster responses and less overthinking, though users can prompt directly for control over thinking rate if needed.
- Default behaviors have changed: response length is calibrated to task complexity (shorter for simple queries, longer for analysis), tool use is less frequent with more reasoning, and subagent spawning is more judicious, requiring explicit guidance for parallel work.
- Opus 4.7 excels at long-running tasks like multi-file changes, debugging, code review, and multi-step agentic work, with recommendations to keep effort at xhigh and leverage its improved performance for tasks where supervision was previously a bottleneck.
