Muse in one minute
The user asks a question. A Muse model processes the available context. Meta AI or an agent environment uses the result to answer or call a tool. Only information and actions accessible to that environment can become part of the task.
Which Muse models are current?
| Name | Purpose and status |
|---|---|
| Muse Spark 1.3 | Latest Spark version; available through Muse Code and Meta Model API since 2 September. |
| Muse Spark 1.2 and 1.1 | Earlier versions still listed in the official offering. |
| Muse Image | Image generation and editing model. |
| Muse Voice Transcribe | Speech-to-text model. |
| Muse Glimmer | Separate open-weight model for local agents. |
Spark 1.3 focuses on coding and tasks with several steps. It can process visual input and use tools within an appropriate environment. A chat window, API call and agent do not automatically have the same capabilities. Muse Code, for example, is a developer product, not another name for Meta AI.
How a request moves through the system
- Request
“Prepare a campaign proposal for these three desk lamps.”
- Context
Product sheets, photographs and the agreed audience form the input.
- Processing
The model compares features and flags missing information.
- Answer or action
The environment displays a proposal or uses permitted tools to prepare a draft.
The useful connection is between context and work. Ask for the supplied source behind each product claim. An attractive Muse Image visual does not prove that dimensions or materials are correct. Review the content and product depiction before publishing a draft.
The personal Muse agent has its own virtual computer and can work with connected services. This enables tasks extending beyond a short conversation. Being able to prepare something does not automatically authorise an agent to pay, send or publish on behalf of a business.
Availability and the distinction from Llama
The agent is rolling out in the US through iOS, Android and muse.ai; communicating through WhatsApp is also part of its design. Muse on AI glasses is announced for a later rollout. This does not confirm general availability in the Netherlands or Spain.
Models have separate access through Meta Model API and Muse Code, with geographic conditions. The current API policy, for example, restricts Muse Image in India. A consumer rollout and a developer rollout are different things.
Muse is not simply a new name for Llama. Llama has its own history, weights and licences. Equally, not all Muse models are closed: Glimmer is available with open weights under Apache 2.0 for local agents. Check each model’s terms rather than assigning one property to the entire family.
