Model Detail
OpenAI: o3 Mini
—OpenAI: o3 Mini is a large language model released by OpenAI. And supports text+file->text inputs.
OpenAI: o3 Mini has been evaluated across multiple task suites. On task-specific evaluations the model scores 42.4% resolved on SWE-Bench.
OpenAI: o3 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 2023-10-31, so newer events will not be reflected in zero-shot answers without retrieval.
OpenAI: o3 Mini is best fit for general-purpose chat and instruction-following workloads, 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.
