01 — Verdict

Too close to call

It is close. Our weighted score puts them within 3 points (Muse Glimmer 30B 57/100, Solar Pro 4 55/100, Solar Pro 3 55/100), so choose by what matters most for your work: Solar Pro 3 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, Solar Pro 3 or Solar Pro 4?

It is close. Our weighted score puts them within 3 points (Muse Glimmer 30B 57/100, Solar Pro 4 55/100, Solar Pro 3 55/100), so choose by what matters most for your work: Solar Pro 3 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, Solar Pro 3 or Solar Pro 4?

Solar Pro 3 is cheaper at $0.25 input / $0.25 output per million tokens (official Upstage API price). Muse Glimmer 30B costs $0.30 input / $1.20 output per million tokens (median across 10 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 $0.25 per million tokens for Solar Pro 3 versus $0.525 for Muse Glimmer 30B (2.1× as much) and $0.525 for Solar Pro 4 (2.1× 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, Solar Pro 3 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, Solar Pro 3 and Solar Pro 4 yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. All three support tool calling for agent workflows.

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 131,072 for Solar Pro 3. Maximum output per response: Muse Glimmer 30B up to 131,072, Solar Pro 3 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; Solar Pro 3 accepts text; Solar Pro 4 accepts text. Muse Glimmer 30B handles the widest range of inputs.

Which is newer?

Muse Glimmer 30B is the newest, released Aug 10, 2026. Solar Pro 4 came out Aug 6, 2026; Solar Pro 3 came out Jan 2026. Knowledge cutoff: Muse Glimmer 30B Jan 4, 2026, Solar Pro 3 Mar 2025, 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 Oct 4, 2026.
