Decision reading

Muse Spark 1.1 has the higher public score, 76.91 versus 36.95, and the 90% score intervals do not overlap.

4 results are shared. Category rows based on different benchmark sets are marked directional and do not name a winner.

Which one for your work

Recommendations appear only when a shared evidence basis or an explicit operating constraint supports the call. Secondary and unsupported use cases stay disclosed below the initial list.

  • Coding work

    Code generation, repair, and software-engineering tasks

    Not enough matched evidence

    The category averages use different weighted benchmark sets, so they are directional rather than like-for-like.

    No shared weighted benchmark basis supports a winner.

What is actually comparable

Shared results can support a head-to-head reading. Results present for only one model describe coverage, not superiority.

Category results, on a stated basis

Each row states whether both averages use the same weighted benchmark set. Directional and not-comparable rows remain visible, but they never receive a winner in this template.

Shape of the matched evidence

Only shared public evidence is shown. Sparse evidence stays a ruled list rather than being closed into a radar shape.

Too few matched category axes support a radar. The ruled list below shows only shared benchmark results; positions use each benchmark’s normalized display scale when available.

What each workload costs

Three fixed token mixes turn per-token rates into comparable decisions. Each scenario states context fit and whether cached input had to fall back to the published list-input rate.

Frequently asked questions

Which is better, Muse Spark 1.1 or Ornith-1.5-9B?

Muse Spark 1.1 has the higher public score, 76.91 versus 36.95, and the 90% score intervals do not overlap. That is the clearest overall quality signal in the current public data.

Which is better for coding, Muse Spark 1.1 or Ornith-1.5-9B?

The current coding averages use different weighted benchmark sets, so BenchLM does not name a winner from them. Read the shared benchmark rows directly and test the models on the same task set.

Which is better for agentic tasks, Muse Spark 1.1 or Ornith-1.5-9B?

The published evidence does not provide a shared weighted agentic tasks basis for both models, so BenchLM does not name a agentic tasks winner.

Which costs less, Muse Spark 1.1 or Ornith-1.5-9B?

Both models do not have comparable published API token rates, so this page does not name a universal price winner.

Which has the larger context window, Muse Spark 1.1 or Ornith-1.5-9B?

Muse Spark 1.1 has the larger documented context window: 1M, compared with 262K.
