Capability Differences Between Claude Opus 5 and GPT-5.6
Claude Opus 5 and GPT-5.6 are both frontier models aimed at agentic coding and long-running work, so the real split is coding depth against price and context size. Opus 5 costs $5 per million input tokens and $25 per million output, runs a 1M-token context, and carries a May 2026 knowledge cutoff. GPT-5.6 Sol is cheaper at $4 input and $20 output per million, with a slightly larger 1.05M-token context.
Choose Opus 5 for sustained coding and multi-step agents. Anthropic tunes the Opus tier for complex agentic coding and enterprise workflows, and 2026 comparisons from Artificial Analysis rank it above GPT-5.6 Sol on their overall intelligence index.
Choose GPT-5.6 Sol when the token bill matters more than the last few points of coding accuracy, or when you need broad general-purpose range across writing, analysis, and multi-modal work. Its current promotional pricing, in effect through at least November 2026, undercuts Opus 5 by about 20% on both input and output.
