GPT-5 vs Claude Opus 4.7
GPT-5 and Claude Opus 4.7 side by side: what each one is, verified plan pricing and install commands where we have them, and the full review of each.
GPT-5
OpenAI's GPT-5 model, released August 2025. Unified fast and reasoning modes in one model. Superseded by the GPT-6 family in September 2026 and now marked deprecated in the API.
Claude Opus 4.7
Anthropic's Opus model released April 2026, since succeeded by Opus 4.8 and Opus 5.5. Strong at coding, long-context analysis, and agentic work. 1M context, $5/$25 per million tokens.

In Depth
GPT-5
GPT-5 is the OpenAI model released in August 2025 that marked a significant jump in reasoning, coding, math, and long-context performance over GPT-4o. It unified the capabilities that were previously split across separate models (GPT-4o for speed, o3 for reasoning) into a single model that adaptively allocates compute based on task difficulty. OpenAI's API docs now list it as a deprecated previous model with a 400K context window at $1.25 per million input tokens and $10 per million output tokens, and point developers to the GPT-6 family: GPT-6 Astra (September 2026) for the most demanding work, GPT-6.1 Sol (September 29, 2026) for near-Astra performance at lower cost, and GPT-6 Luna for high-volume tasks. Keep GPT-5 only for existing integrations you have not migrated yet.
Claude Opus 4.7
Claude Opus 4.7 was Anthropic's top Opus model when it shipped in April 2026, with a focus on staying coherent across long agent runs and a 1M token context window for whole-codebase reasoning. It is priced at $5 per million input tokens and $25 per million output tokens. Anthropic has since released Claude Opus 4.8 (May 28, 2026) and Claude Opus 5.5 (September 22, 2026), and as of October 2026 Opus 5.5 is the default model in Claude Code. Opus 4.7 remains active in the API, with retirement not sooner than April 16, 2027, so pin it only if your evals depend on its behavior.
