Model Detail
OpenAI: o4 Mini
—OpenAI: o4 Mini is a multimodal model released by OpenAI. And supports text+image+file->text inputs.
OpenAI: o4 Mini has been evaluated across multiple task suites. On task-specific evaluations the model scores 74.4% resolved on SWE-Bench.
OpenAI: o4 Mini is priced at $1.1/M input tokens and $4.4/M output tokens. Operationally the model offers a 200K-token context window, which matters when sizing it for prompt-heavy or latency-sensitive workloads. Pricing in this range is the working middle of the API market — neither the cheapest nor the most expensive option per token, so cost-fit is usually a function of how much output you generate.
The published knowledge cutoff is 2024-06-30, so newer events will not be reflected in zero-shot answers without retrieval.
OpenAI: o4 Mini is best fit for mixed text-and-image reasoning tasks such as document understanding, and long-context tasks such as full-codebase analysis or book-length summarization (200K tokens). Treat this as a starting matrix rather than a benchmark verdict — the right deployment usually depends on the specific evaluation suite that mirrors your workload.
Retiring GPT-4o, GPT-4.1, GPT-4.1 mini, and OpenAI o4-mini in ChatGPT
On February 13, 2026, alongside the previously announced retirement of GPT‑5 (Instant, Thinking, and Pro), we will retire GPT‑4o, GPT‑4.1, GPT‑4.1 mini, and OpenAI o4-mini from ChatGPT. In the API, there are no changes at this time.
Addendum to OpenAI o3 and o4-mini system card: OpenAI o3 Operator
We are replacing the existing GPT-4o-based model for Operator with a version based on OpenAI o3. The API version will remain based on 4o.
Shipping code faster with o3, o4-mini, and GPT-4.1
CodeRabbit uses OpenAI models to revolutionize code reviews—boosting accuracy, accelerating PR merges, and helping developers ship faster with fewer bugs and higher ROI.
Addendum to o3 and o4-mini system card: Codex
Codex is a cloud-based coding agent. Codex is powered by codex-1, a version of OpenAI o3 optimized for software engineering. codex-1 was trained using reinforcement learning on real-world coding tasks in a variety of environments to generate code that closely mirrors human style and PR preferences,
