# MiMo API

MiMo API via RunAPI — base mimo-v2.5 supports text and remote HTTP(S) images in synchronous OpenAI Chat Completions; mimo-v2.5-pro remains text-only.

**Provider:** Xiaomi
**Modality:** Text
**Catalog:** 2 variants

MiMo 2.5 is a language-model family. Both models support text-only requests through Chat Completions, Responses, and Anthropic Messages on their existing synchronous and SSE paths. Base mimo-v2.5 additionally accepts remote HTTP(S) image_url parts in messages[].content[] only for synchronous OpenAI Chat Completions. mimo-v2.5-pro is text-only; image input through Responses, Anthropic Messages, streaming/SSE, data URLs, and audio/file/video is not verified.

## Context

RunAPI supports text-only requests for both MiMo models through Chat Completions, Responses, and Anthropic Messages on their existing synchronous and SSE paths. The only verified image shape is base mimo-v2.5 with synchronous OpenAI Chat Completions, where messages[].content[] may contain text and remote HTTP(S) image_url parts. Pro remains text-only; other image and media shapes are closed or unverified.

## FAQ

### Which variant should I start with?

Pick the cheapest variant that meets your quality bar. Most teams start on the fast variant and graduate to pro for production.

### Is there a free tier?

New accounts get free first calls on every model. After that, pay per call.

### Do you stream results?

Where streaming is available, RunAPI streams end-to-end.

### How are failures billed?

Failed generations are not charged.

### Are outputs cached?

Generated outputs are stored and retrievable by task ID. Inputs are not cached.

### Can I use commercially?

Yes — commercial use is included for every variant unless a model license explicitly restricts it, which is called out on the variant page.

### What about rate limits?

Per-key rate limits scale with usage tier. See pricing page for current limits.

### Where can I report issues?

Open an issue on the public GitHub repo or email support.
