01 — Verdict

Too close to call

It is close. Our weighted score puts them within 1 points (Ornith 1.5 35B A3B 59/100, Muse Glimmer 30B 57/100, Seed 2.1 Pro 50/100), so choose by what matters most for your work: Muse Glimmer 30B on price and Ornith 1.5 35B A3B 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, Ornith 1.5 35B A3B or Seed 2.1 Pro?

It is close. Our weighted score puts them within 1 points (Ornith 1.5 35B A3B 59/100, Muse Glimmer 30B 57/100, Seed 2.1 Pro 50/100), so choose by what matters most for your work: Muse Glimmer 30B on price and Ornith 1.5 35B A3B 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, Ornith 1.5 35B A3B or Seed 2.1 Pro?

Muse Glimmer 30B is cheaper at $0.30 input / $1.20 output per million tokens (median across 10 API providers). Ornith 1.5 35B A3B costs $0.20 input / $1.70 output per million tokens (median across 2 API providers); Seed 2.1 Pro costs $0.891 input / $4.45 output per million tokens (official Volcengine Ark API price). At a typical mix of three input tokens to one output token, that is $0.525 per million tokens for Muse Glimmer 30B versus $0.575 for Ornith 1.5 35B A3B (1.1× as much) and $1.78 for Seed 2.1 Pro (3.4× 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, Ornith 1.5 35B A3B has not been scored yet and Seed 2.1 Pro has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Muse Glimmer 30B, Ornith 1.5 35B A3B and Seed 2.1 Pro 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?

Ornith 1.5 35B A3B has the largest context window at 262,144 tokens, against 256,000 for Seed 2.1 Pro and 131,072 for Muse Glimmer 30B. Maximum output per response: Muse Glimmer 30B up to 131,072, Seed 2.1 Pro up to 256,000 tokens.

Muse Glimmer 30B and Ornith 1.5 35B A3B publishes its weights (Apache 2.0 and MIT) and can be self-hosted; Seed 2.1 Pro is proprietary.

Which is newer?

Ornith 1.5 35B A3B is the newest, released Aug 18, 2026. Muse Glimmer 30B came out Aug 10, 2026; Seed 2.1 Pro came out Jun 23, 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.
