Muse Glimmer 30B Overview

Muse Glimmer 30B is a dense vision language model from Meta built for long-horizon agentic work on local hardware. The architecture pairs a 52-layer causal text decoder with a roughly 1.8B parameter ViT-G/14 perception encoder for about 29.6 billion parameters in total, and it accepts interleaved text and image input so an agent can interpret screenshots, charts, and documents alongside conversation. The decoder uses grouped-query attention with 32 query heads and 2 key-value heads, a repeating pattern of three sliding-window local attention layers followed by one global layer, SwiGLU feed-forward blocks, and rotary position embeddings applied on the local layers, supporting a trained context of 131,072 tokens.

Muse Glimmer 30B Pricing

Muse Glimmer 30B costs $0.300 per 1M input tokens and $1.20 per 1M output tokens.

Deploy Muse Glimmer 30B with an API

Muse Glimmer 30B runs as a hosted REST endpoint through Roboflow Workflows. Pick a task, then hand the prompt to your coding agent or copy the code. Deploying the workflow into a free Roboflow workspace replaces the your-workspace and YOUR_API_KEY placeholders with your own.

Connect your agent to Roboflow (once)

Add the Roboflow MCP server

claude mcp add --transport http roboflow https://mcp.roboflow.com/mcp

Run /mcp and authorize Roboflow in your browser when the OAuth flow opens.

Start a new Claude Code session so the MCP loads, then paste the prompt below (it works the same in any agent).

Deploy this workflow to your Roboflow workspace to use it.

Integrate the Roboflow "Muse Glimmer 30B" workflow into my app.

- Endpoint: POST https://serverless.roboflow.com/<your-workspace>/workflows/muse-glimmer-30b-captioning
- Auth: send my Roboflow API key as `api_key` in the request body, read from the ROBOFLOW_API_KEY env var (never hardcode).
- Body: { "api_key": ..., "inputs": { `image`: { type: "url" | "base64", value } } }.
- Billing: this workflow needs no provider API key — inference runs on my Roboflow credits. A BYO provider key can be added to the model step in the Roboflow workflow editor later.

With the Roboflow MCP connected, call `workflows_get` on "muse-glimmer-30b-captioning" to read the exact input schema (the source of truth), then `workflows_run` on a sample image to confirm the output shape before writing code (the MCP is authenticated, so this needs no key). Without the MCP, use the contract above.

Before running the app, set up these keys so it does not error at runtime:
- `ROBOFLOW_API_KEY` (sent as `api_key`) from https://app.roboflow.com/settings/api
Create a .gitignore'd .env with these variables, using placeholder values for any I haven't given you. Then pause and tell me directly, in your reply: the full path to the .env file, exactly which keys I need to paste in, and the link to get each one. Wait for me to confirm I've added them before you run anything. Do not run the app until I confirm.

Then add the integration to my codebase: match my project's language, framework, and conventions; read every key from environment variables (never hardcode); add basic error handling; and include a small runnable example. If you can't tell what language my project uses, ask me.

Frequently Asked Questions About Muse Glimmer 30B Vision

Yes. Muse Glimmer 30B accepts image input and handles OCR, object counting, identification, visual reasoning, and object detection. On Roboflow's Vision Evals its strongest task is Counting at 66.2% (#32 of 68 at low effort). You can test it on your own image in the demo above.

Yes. it scores 60.7% (#32 of 52 at low effort) on Vision Evals OCR, which covers single readings, full transcriptions, structured JSON, and locating text with boxes. Within that, full transcriptions score 82.9%, and returning the fields of a label or form as JSON scores 80.2%.

Not its strength. On Vision Evals, Muse Glimmer 30B scores 41% mAP@50 on object detection (#49 of 68 at low effort) and 66.2% judge-graded accuracy on object counting. For production counting or precise localization, pairing it with a specialized detector like RF-DETR or your own trained model in a Roboflow Workflow is usually more reliable: detect the objects, then count the detections.

On our benchmark's task mix, Muse Glimmer 30B averages $0.0013 per sample at $0.30 per 1M input and $1.20 per 1M output tokens (#20 of 68 on cost), with an average speed of 10.6s per sample across the benchmark. Actual cost depends on your images and prompts.

On the overall Vision Evals ranking, Muse Glimmer 30B sits #39 of 68 at 61.4%, just behind Gemini 3.5 Flash-Lite (61.7%) and just ahead of Qwen3.8 Flash (59.7%). See the full side-by-side: Muse Glimmer 30B vs Gemini 3.5 Flash-Lite.
