More about gpt-4.1-mini
GPT-4.1 Mini is OpenAI's cost-optimized small model, available free through GitHub Models. With a 1M-token context window — matching the full GPT-4.1 — and 32K max output, it punches above its weight class for long-context tasks like document Q&A, full-codebase analysis, and multi-turn conversations. The trade-off versus full GPT-4.1 is lower reasoning depth on complex tasks. Rate-limited to 15 RPM and 150 requests per day with per-request caps (8K input / 4K output), it is generous enough for prototyping and personal projects. Fully OpenAI SDK-compatible; requires only a GitHub account.
