GPT-5 vs Claude Sonnet 4: side-by-side benchmarks, pricing, context windows, coding ability and deployment. Pick the right model for your stack.
Overview
Claude Sonnet 4: Claude Sonnet 4 is Anthropic's May 2025 hybrid-reasoning model for coding, visual reasoning, tool use, and agent workflows. The dated claude-sonnet-4-20250514 snapshot was retired on Anthropic-operated platforms on June 15, 2026 and is retained as a historical evaluation and migration reference.
GPT-5: GPT-5 is OpenAI's August 2025 reasoning model for coding, reasoning, and agentic tasks. The API model supports text input and output, image input, configurable reasoning effort, and an immutable gpt-5-2025-08-07 snapshot; OpenAI now classifies it as a previous-generation model.
Context window: Claude Sonnet 4 accepts up to 200,000 tokens, GPT-5 up to 400,000. Confirm the limit for your specific deployment channel before relying on it.
