Muse Spark 1.2 is Meta's reasoning model for complex agent tasks. It reads text, images, video and PDFs over a 1M-token context and works as a main agent that plans and delegates or as a sub-agent running in parallel. In Meta's testing it does well on multi-file refactors, long debugging sessions, generating whole repositories and tasks that go far beyond one prompt.
It accepts text, image, file (PDF) and video input and returns text, and supports tool calling, structured JSON output and streaming. It always reasons before answering, and you choose how hard it thinks with the reasoning effort setting. Muse Spark 1.2 is commonly used for multi-file refactors, long debugging sessions, multi-agent systems and repository-scale code generation. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.
Pricing is usage-based: $1.25 per million input tokens and $4.25 per million output tokens. There is no fixed monthly fee, and you pay only for the tokens you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
