o3 Pro vs GPT-4.1
o3 Pro vs GPT-4.1: side-by-side benchmarks, pricing, context windows, coding ability and deployment. Pick the right model for your stack.
Overview
GPT-4.1: GPT-4.1 is OpenAI's April 2025 API-only model, built for instruction following and tool calling without a reasoning step. It accepts text and image input across a 1,047,576-token context window, returns up to 32,768 tokens, and carries a June 2024 knowledge cutoff — roughly eight times GPT-4o's context at lower per-token pricing. OpenAI has since deprecated it, scheduling the gpt-4.1-2025-04-14 snapshot to shut down on 14 January 2027 with gpt-6-luna as the replacement.
o3 Pro: o3 Pro is OpenAI's highest-capability reasoning model, applying extended compute at inference time to solve complex scientific, mathematical, and programming problems. It achieved the highest published scores on ARC-AGI-2 and competitive programming benchmarks at its June 2025 release.
Context window: GPT-4.1 accepts up to 1,000,000 tokens, o3 Pro up to 200,000. Confirm the limit for your specific deployment channel before relying on it.
