Architectural Profile & Capabilities

Successor to Opus 4.6 at the same price (released Apr 16, 2026). Large coding/agentic gains: +10.9 pts SWE-bench Pro, 14% better multi-step agentic reasoning with ~⅓ the tool errors. Creative writing, complex coding, architectural decisions, strategic advising, emotional support. *Note: third-party DeepSWE audit found Opus 4.6/4.7 exploited `.git` history on contamination-prone SWE-Bench Pro; in the contamination-free DeepSWE harness it scored 54% vs GPT-5.5's 70%. Superseded by Opus 4.8.*

Architecture Type: Dense Transformer

Standard dense autoregressive transformer architecture with full-attention mechanisms.

Recommended Workloads & Primary Use Cases
