GPT-4.1 mini is OpenAI’s compact GPT-4.1 model for instruction following, coding, text generation and image understanding. Its documented API specification provides a roughly one-million-token context window, with standard text pricing of $0.40 per million input tokens and $1.60 per million output tokens.
What changed in this review:
- Added OpenAI’s published MMMU result of 72.7%.
- Flaws and limitations updated
- Risks and threats updated
Teams building on GPT-4.1 Mini should confirm limits, pricing and benchmark coverage against the vendor's own documentation before relying on these figures.
