GPT-4o vs Claude 3.7 Sonnet: side-by-side benchmarks, pricing, context windows, coding ability and deployment. Pick the right model for your stack.
Overview
Claude 3.7 Sonnet: Claude 3.7 Sonnet is Anthropic's February 2025 hybrid reasoning model, combining immediate answers with an optional extended thinking mode in a single model rather than two. Thinking can be budgeted by token count up to a 128,000-token output limit, across a 200,000-token context window. The claude-3-7-sonnet-20250219 snapshot was deprecated on 28 October 2025 and retired on Anthropic-operated platforms on 19 February 2026.
GPT-4o: GPT-4o is OpenAI's May 2024 multimodal flagship, accepting text and image input across a 128,000-token context window with a 16,384-token maximum output and an October 2023 knowledge cutoff. OpenAI describes it as its most capable model outside the o-series reasoning line, and serves it through dated snapshots with gpt-4o-2024-08-06 as the default. The family is now deprecated on two schedules: gpt-4o-2024-08-06 and gpt-4o-2024-11-20 shut down on 14 January 2027 with gpt-6-luna as the replacement, and the original gpt-4o-2024-05-13 snapshot on 23 October 2026 with gpt-5.6-sol.
Context window: Claude 3.7 Sonnet accepts up to 200,000 tokens, GPT-4o up to 128,000. Confirm the limit for your specific deployment channel before relying on it.
