GPT-4.1 Mini
GPT-4.1 mini provides a balance between intelligence, speed, and cost that makes it an attractive model for many use cases.
OpenAI Balanced intelligence, speed, and cost for developers
GPT-4.1 Mini is a text generation model developed by OpenAI, released as part of the GPT-4.1 model family in April 2025. It is designed to occupy a middle ground between the full GPT-4.1 model and lighter-weight options, offering a context window of over one million tokens — specifically 1,047,576 tokens. The model has a training data cutoff of May 31, 2024, and is accessible via the OpenAI API.
GPT-4.1 Mini is positioned for use cases where developers need a capable text generation model without the latency or cost profile of larger models. Its large context window makes it suitable for tasks involving long documents, extended conversations, or multi-step instructions. It fits well into applications that require a balance of response quality, throughput, and cost efficiency.
What GPT-4.1 Mini supports
Long Context Processing
Handles input and output across a context window of 1,047,576 tokens, enabling processing of very long documents or extended multi-turn conversations in a single request.
Text Generation
Generates coherent, instruction-following text responses for tasks such as summarization, drafting, Q&A, and content creation.
Instruction Following
Responds to detailed, multi-step instructions with structured outputs, making it suitable for agentic workflows and complex task completion.
Code Assistance
Generates, explains, and debugs code across common programming languages as part of its general text generation capabilities.
API Integration
Available via the OpenAI API under the model ID gpt-4.1-mini, allowing direct integration into applications and pipelines.
