01 — Verdict

Too close to call

It is close. Our weighted score puts them within a point (Solar Pro 4 53/100, Muse Glimmer 30B 53/100, Perceptron Mk1 45/100), so choose by what matters most for your work: Perceptron Mk1 on price and Solar Pro 4 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.

04 — Questions

Which should you choose?

Which is better: Muse Glimmer 30B, Perceptron Mk1 or Solar Pro 4?

It is close. Our weighted score puts them within a point (Solar Pro 4 53/100, Muse Glimmer 30B 53/100, Perceptron Mk1 45/100), so choose by what matters most for your work: Perceptron Mk1 on price and Solar Pro 4 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 is cheaper, Muse Glimmer 30B, Perceptron Mk1 or Solar Pro 4?

Perceptron Mk1 is cheaper at $0.15 input / $1.50 output per million tokens (median across 3 API providers). Muse Glimmer 30B costs $0.30 input / $1.20 output per million tokens (median across 11 API providers); Solar Pro 4 costs $0.30 input / $1.20 output per million tokens (official Upstage API price). At a typical mix of three input tokens to one output token, that is $0.487 per million tokens for Perceptron Mk1 versus $0.525 for Muse Glimmer 30B (1.1× as much) and $0.525 for Solar Pro 4 (1.1× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. Muse Glimmer 30B has not been scored yet, Perceptron Mk1 has not been scored yet and Solar Pro 4 has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Muse Glimmer 30B, Perceptron Mk1 and Solar Pro 4 yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Perceptron Mk1 does not support tool calling, which most coding agents need.

Which has the bigger context window?

Solar Pro 4 has the largest context window at 524,288 tokens, against 131,072 for Muse Glimmer 30B and 32,768 for Perceptron Mk1. Maximum output per response: Muse Glimmer 30B up to 131,072, Perceptron Mk1 up to 8,192, Solar Pro 4 up to 131,072 tokens.

Which can read images, PDFs, audio or video?

Muse Glimmer 30B accepts text and images; Perceptron Mk1 accepts text, images and video; Solar Pro 4 accepts text. Perceptron Mk1 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; Perceptron Mk1 and Solar Pro 4 is proprietary.

Which is newer?

Muse Glimmer 30B is the newest, released Aug 10, 2026. Solar Pro 4 came out Aug 6, 2026; Perceptron Mk1 came out May 12, 2026. Knowledge cutoff: Muse Glimmer 30B Jan 4, 2026, Solar Pro 4 Feb 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 Nov 2, 2026.
