- R · What Makes It Special
- OpenAI's GPT-4.1 nano (April 14, 2025), the smallest GPT-4.1 model and, at launch, OpenAI's fastest and cheapest, for tasks that demand low latency; it scored 80.1% on MMLU, 50.3% on GPQA and 9.8% on Aider polyglot coding, excels at instruction following and tool calling, takes text and images with a context window of about 1M tokens, and costs $0.10/$0.40 per million tokens. OpenAI removes it from the API October 23, 2026, recommending GPT-5.6 Luna.
