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 is a multimodal AI model from OpenAI. It costs $2.000 per million input tokens and $8.000 per million output tokens (blended $3.800/M), with a 1M-token context window.
GPT-4.1 costs $2.000 per million input tokens and $8.000 per million output tokens, for a blended reference rate of $3.800 per million tokens.
GPT-4.1 supports up to 1M tokens of context (1,000,000 tokens).
GPT-4.1 is well suited to 1M context window, Strong coding and Better instruction following than GPT-4o.
GPT-4.1 is developed and served by OpenAI. It was released in Apr 2025.
