o4 Mini is a compact reasoning model tuned for fast, cost-efficient multimodal and agentic work. o4 Mini is a compact o-series reasoning model optimized for fast, cost-efficient performance while keeping strong multimodal and agentic capabilities. It supports tool use and chains tools, generates structured outputs and solves multi-step tasks with low latency. It supports a context window of up to 200K tokens, with training data through Jun 2024.

o4 Mini is served through Hormouz behind an OpenAI-compatible API. It supports tool calling, image (vision) input and step-by-step reasoning. Point your base URL at Hormouz and drop in a Hormouz key, and existing OpenAI SDK code runs unchanged.

Pricing is usage-based: $1.1 per million input tokens and $4.4 per million output tokens. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
