    GPT-4.1 mini is OpenAI’s compact GPT-4.1 model for text and image understanding, instruction following, and tool-assisted applications. Its documented specifications include a roughly one-million-token context window and standard API pricing of $0.40 per million input tokens and $1.60 per million output tokens.

    Capabilities

    • Accepts text and image inputs and generates text outputs.
    • Not yet confirmed by public reporting.
    • Supports function calling for applications that connect the model to external tools.
    • Supports structured outputs for schema-constrained responses.
    • Generates and edits code, with published software-engineering evaluations.

    What improved

    • Expands the context window from GPT-4o mini’s 128,000 tokens to 1,047,576 tokens.
    • Increases maximum output length from GPT-4o mini’s 16,384 tokens to 32,768 tokens.
    • Improves instruction following relative to GPT-4o mini in OpenAI’s launch evaluations.
    • Improves scientific reasoning and multimodal understanding relative to GPT-4o mini in OpenAI’s launch evaluations.

    Known flaws & limitations

    • Its June 2024 knowledge cutoff means recent facts require external sources.
    • Output is limited to 32,768 tokens, substantially less than the input context capacity.
    • It does not provide native audio input or output.
    • Published software-engineering performance trails the full GPT-4.1 model.
    • A large context window does not guarantee reliable retrieval or reasoning across every supplied detail.

    Risks, safety & security issues

    • Incorrect factual answers can mislead users, particularly when used without independent verification in consequential decisions.
    • Generated code and patches can contain defects; benchmark performance does not establish production safety.
    • Outdated knowledge can produce misleading guidance about changing events, policies, or requirements.

    Good fit for

    • High-volume document summarization, classification, and information extraction.
    • Tool-connected assistants that require structured responses.
    • Image-assisted document understanding and question answering.
    • Routine code generation and editing with tests and human review.

    Poor fit for

    • Native real-time audio conversations.
    • Unsupervised high-stakes decisions requiring consistently accurate factual judgments.
    • Difficult autonomous software-engineering work without testing and review.
    • Current-events answers without access to reliable external sources.

    Profile last reviewed 10/27/2026 and re-checked automatically every few hours against the vendor's published documentation, papers and public leaderboards. Scores come from the cited benchmark results above — confirm limits and pricing against the provider's own documentation before building on them.
