GPT-4.1 Nano (batch)
Long-context coding-focused GPT-4 successor with a 1M-token window. Aimed at developers who need predictable instruction following over very long inputs.
GPT-4.1 Nano (batch) is a multimodal AI model from OpenAI. It costs $0.050 per million input tokens and $0.200 per million output tokens (blended $0.095/M), with a 1,047,576-token context window.
Profile inherited from upstream GPT-4.1 ↗ — this is a hosted variant of the same open-weights model.
- 1M context window
- Strong coding
- Better instruction following than GPT-4o
- Cheap relative to GPT-4
- Repo-scale coding
- Long document analysis
- Cost-sensitive vision
