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, MiniCPM5-2B 53/100), so choose by what matters most for your work: MiniCPM5-2B 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: Solar Pro 4, MiniCPM5-2B or Muse Glimmer 30B?

It is close. Our weighted score puts them within 3 points (Muse Glimmer 30B 57/100, Solar Pro 4 55/100, MiniCPM5-2B 53/100), so choose by what matters most for your work: MiniCPM5-2B 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, Solar Pro 4, MiniCPM5-2B or Muse Glimmer 30B?

MiniCPM5-2B is cheaper at $0.124 input / $0.743 output per million tokens (median across 1 API provider). Solar Pro 4 costs $0.30 input / $1.20 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). At a typical mix of three input tokens to one output token, that is $0.279 per million tokens for MiniCPM5-2B versus $0.525 for Solar Pro 4 (1.9× as much) and $0.525 for Muse Glimmer 30B (1.9× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. Solar Pro 4 has not been scored yet, MiniCPM5-2B has not been scored yet and Muse Glimmer 30B has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Solar Pro 4, MiniCPM5-2B and Muse Glimmer 30B 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 MiniCPM5-2B and 131,072 for Muse Glimmer 30B. Maximum output per response: Solar Pro 4 up to 131,072, MiniCPM5-2B up to 131,072, Muse Glimmer 30B up to 131,072 tokens.

Are any of these open source?

MiniCPM5-2B and Muse Glimmer 30B publishes its weights (apache-2.0 and Apache 2.0) and can be self-hosted; Solar Pro 4 is proprietary.

Which is newer?

MiniCPM5-2B is the newest, released Sep 6, 2026. Muse Glimmer 30B came out Aug 10, 2026; Solar Pro 4 came out Aug 6, 2026. Knowledge cutoff: Solar Pro 4 Feb 2026, 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.
