GPT-4.1 Mini is a mid-sized model with a ~1M-token context at much lower latency and cost than the flagship. GPT-4.1 Mini keeps the large context window while trading some peak quality for substantially lower latency and price. It supports a context window of up to 1M tokens, with training data through Jun 2024.

GPT-4.1 Mini is served through Hormouz behind an OpenAI-compatible API. It supports tool calling and image (vision) input. Point your base URL at Hormouz and drop in a Hormouz key, and existing OpenAI SDK code runs unchanged.

Pricing is usage-based: $0.4 per million input tokens and $1.6 per million output tokens. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.

GPT-4.1 Mini is a mid-sized model delivering performance competitive with GPT-4o at substantially lower latency and cost. It retains a 1 million token context window and scores 45.1% on hard...
