Claude Opus 4.6 vs Muse Spark 1.1

Published LiveBench scores across all seven categories, live list pricing, context windows, and the measured cost of a point of capability — for both models, side by side.

OpenRouter + LiveBenchAll comparisonsFull leaderboard

Effectively the same quality — Muse Spark 1.1 is the cheaper way to get it.

The two are within 0.8 points overall, which is inside the range that effort settings alone move a LiveBench score, so treat them as quality-equivalent. Muse Spark 1.1 lists 5.0× cheaper per blended million tokens. When quality ties, cost is the whole decision. Muse Spark 1.1 also leads on measured cost per point of capability, at $0.1139 per point.

Claude Opus 4.6 vs Muse Spark 1.1 FAQ

Which is better, Claude Opus 4.6 or Muse Spark 1.1?

Effectively the same quality — Muse Spark 1.1 is the cheaper way to get it. The two are within 0.8 points overall, which is inside the range that effort settings alone move a LiveBench score, so treat them as quality-equivalent. Muse Spark 1.1 lists 5.0× cheaper per blended million tokens. When quality ties, cost is the whole decision. Muse Spark 1.1 also leads on measured cost per point of capability, at $0.1139 per point.

Is Claude Opus 4.6 cheaper than Muse Spark 1.1?

Muse Spark 1.1 is cheaper. On a 3:1 input:output blend, Claude Opus 4.6 lists at $10.00 per million tokens and Muse Spark 1.1 at $2.00 — Muse Spark 1.1 is 5.0× cheaper. Input and output are priced separately — Claude Opus 4.6 charges $5.00 in and $25.00 out, Muse Spark 1.1 charges $1.25 and $4.25 — so the model that looks cheaper flips depending on how output-heavy your workload is.

Claude Opus 4.6 vs Muse Spark 1.1: which scores higher on benchmarks?

Claude Opus 4.6 scores 74.5 and Muse Spark 1.1 scores 75.3 overall on LiveBench, the mean of its seven categories. That gap is inside the range that effort settings alone move a score, so treat them as equivalent on published quality. Category scores differ from the overall figure — a model can lead on reasoning and trail on coding, which the per-category table above breaks out.

Which gives better value for money, Claude Opus 4.6 or Muse Spark 1.1?

Muse Spark 1.1. Cost per point divides the measured dollars LiveBench spent running the benchmark by the score it earned, so it captures something token pricing misses: a reasoning model can emit many times more tokens than its per-token rate suggests. Claude Opus 4.6 works out at $0.2101 per point and Muse Spark 1.1 at $0.1139.

Does Claude Opus 4.6 or Muse Spark 1.1 have a bigger context window?

They are effectively the same — 1M for Claude Opus 4.6 and 1.0M for Muse Spark 1.1.

Do Claude Opus 4.6 and Muse Spark 1.1 support prompt caching?

Both publish a cached-input rate: $0.500 per million for Claude Opus 4.6 and $0.150 for Muse Spark 1.1, against full input rates of $5.00 and $1.25. On a workload with a long stable prefix — a system prompt, a tool schema, a retrieved corpus — that changes the economics more than the headline price does.

How these numbers are produced

  • Price — provider list price from OpenRouter, refreshed every 15 minutes. “Blended” is a 3:1 input:output mix.
  • ScoresLiveBench release 2026-06-25, using their own category map. Each model shows its strongest published run. A blank means “not evaluated”, never “bad”.
  • Cost per point — the measured dollars LiveBench spent on the run, divided by the score it earned.
  • “Win” — awarded only past a threshold: one full point on a benchmark score, 10% on a price, 25% on a context window. Anything tighter reports as a tie, because effort settings alone move a LiveBench score by more than that.
