01 — Verdict

Too close to call

It is close. Our weighted score puts them within 2 points (Muse Spark 1.3 60/100, Muse Glimmer 30B 57/100), so choose by what matters most for your work: Muse Glimmer 30B on price and Muse Spark 1.3 for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Which can read images, PDFs, audio or video?

Muse Glimmer 30B accepts text and images; Muse Spark 1.3 accepts text, images, PDFs, audio and video. Muse Spark 1.3 handles the widest range of inputs.

Are any of these open source?

Muse Glimmer 30B publishes its weights (Apache 2.0) and can be self-hosted; Muse Spark 1.3 is proprietary.

Which is newer?

Muse Spark 1.3 is the newest, released Sep 2, 2026. Muse Glimmer 30B came out Aug 10, 2026. Knowledge cutoff: Muse Glimmer 30B Jan 4, 2026.

How do you decide the winner?

Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
