Hy4 preview vs Muse Spark 1.1
Updated August 28, 2026. Public scores include evidence status and uncertainty. They are not guarantees for a specific workload.
Decision reading
Hy4 preview has the higher public score estimate, 79.16 versus 77.14, but the 90% score intervals overlap. Treat that as a lead, not a settled winner.
6 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.

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

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.

Frequently asked questions
Which is better, Hy4 preview or Muse Spark 1.1?
Hy4 preview has the higher public score estimate, 79.16 versus 77.14, but the 90% score intervals overlap. The higher estimate is not a decisive winner because the uncertainty ranges overlap.
Which is better for coding, Hy4 preview or Muse Spark 1.1?
Hy4 preview leads the like-for-like coding comparison across 1 shared weighted benchmark row.
Which is better for agentic tasks, Hy4 preview or Muse Spark 1.1?
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, Hy4 preview or Muse Spark 1.1?
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, Hy4 preview or Muse Spark 1.1?
Both models list the same context window, 1M.
