o4 Mini vs GPT-5 Mini — Benchmarks, Pricing & Coding Compar…
o4 Mini vs GPT-5 Mini: side-by-side benchmarks, pricing, context windows, coding ability and deployment. Pick the right model for your stack.
Overview
GPT-5 Mini: GPT-5 Mini is OpenAI's August 2025 cost-efficient reasoning model for well-defined, latency-sensitive, and high-volume workloads. The API model supports text input and output, image input, configurable reasoning effort, and an immutable gpt-5-mini-2025-08-07 snapshot; OpenAI now classifies it as a previous-generation model.
o4 Mini: o4 Mini is OpenAI's next-generation efficient reasoning model adding vision support to the mini reasoning tier. It is optimized for agentic tasks requiring both image understanding and step-by-step logic at low cost-per-task.
Context window: GPT-5 Mini accepts up to 400,000 tokens, o4 Mini up to 200,000. Confirm the limit for your specific deployment channel before relying on it.
