o4 Mini vs GPT-4.1 Mini
o4 Mini vs GPT-4.1 Mini: side-by-side benchmarks, pricing, context windows, coding ability and deployment. Pick the right model for your stack.
Overview
GPT-4.1 Mini: GPT-4.1 Mini is OpenAI's April 2025 smaller, faster GPT-4.1 variant, carrying the same 1,047,576-token context window, 32,768-token maximum output and June 2024 knowledge cutoff as the full model at roughly a fifth of its input price. It accepts text and image input and, like GPT-4.1, answers without a reasoning step. OpenAI has since deprecated it, scheduling the gpt-4.1-mini-2025-04-14 snapshot to shut down on 14 January 2027 with gpt-6-luna as the replacement.
o4 Mini: o4 Mini is OpenAI's efficient reasoning model, adding vision support to the mini reasoning tier for agentic tasks needing both image understanding and step-by-step logic at low cost per task. It is now deprecated: OpenAI gives the o4-mini-2025-04-16 snapshot and the o4-mini alias a shutdown date of 23 October 2026, with gpt-5.6-terra as the substitute.
Context window: GPT-4.1 Mini accepts up to 1,000,000 tokens, o4 Mini up to 200,000. Confirm the limit for your specific deployment channel before relying on it.
