Muse Image makes and edits pictures from a written description, with optional reference pictures. It thinks before it draws, breaks multi-part requests into steps, and can search the web for factual requests. It writes readable text inside the picture, keeps a style or subject steady across a series, and edits by taking the previous result back with a fresh instruction.
Muse Voice Transcribe 1.0 turns speech into text in a single step. Send a single-channel WAV recording of up to 10 minutes and get the transcript back. It handles push-to-talk, finding where a speaker stops, and separate speakers, and you can steer it toward specialist terms or a language with a hint. It gives no word-by-word timing or confidence scores, so convert recordings in other formats to WAV first.
Muse Spark 1.3 Contributor is the lower-cost tier of Muse Spark 1.3, with the same text, picture, video and PDF input and thousand-page memory, for experiments, learning and early automated and coding projects. It keeps track of information across long tasks and works through conflicting information. For the previous release at this tier, use 1.2 Contributor.
#2 for websites · Muse Spark 1.3 is a Meta model that thinks before it answers, reading text, pictures, video and PDFs and replying in text, with about a thousand pages in mind at once. It is built for long-running automated and coding work: it keeps track of facts across a long task, works through conflicting information and asks you to clarify or confirm when it needs to, keeping its steps concise. Meta does not use your requests to improve its products.
