Summary indices and deep benchmarks

In the composite intelligence index Claude Opus 5 scores 60.7 while Muse Spark 1.1 reaches 50.6. In the coding index Claude Opus 5 leads with 78 against 71.3 for Muse Spark 1.1.

In deep benchmarks Claude Opus 5 excels at expert-level questions across disciplines (HLE) with 52.6 and at graduate-level science questions (GPQA Diamond) with 93.2. Muse Spark 1.1 edges ahead in scientific algorithm programming (SciCode) with 58.2 versus 55.7 for Claude Opus 5. For long-context understanding (LCR) Claude Opus 5 scores 70 compared with 63.3 for Muse Spark 1.1.

What the numbers mean for practice

The composite indices suggest Claude Opus 5 is more versatile for demanding tasks such as scientific research or complex multi-step queries. Muse Spark 1.1 distinguishes itself in scientific algorithm programming where its 58.2 surpasses Claude Opus 5.

Speed and latency

Processing speed is a further decisive factor. Claude Opus 5 delivers 56.1 tokens per second while Muse Spark 1.1 achieves 134.9 tokens per second, making Muse Spark 1.1 substantially faster for applications that require immediate throughput. Time to first token (TTFT) tells a similar story: Claude Opus 5 takes 27.76 seconds whereas Muse Spark 1.1 needs only 1.59 seconds, again favouring the faster start of Muse Spark 1.1.

Choosing between the two models

Organisations focused on science, research or long-document work will find Claude Opus 5 the clearer choice because of its higher scores in the relevant benchmarks. Its higher price of 10 USD per million tokens is justified where answer quality and depth are critical.

If priority lies with speed and lower operating cost, Muse Spark 1.1 offers five times cheaper inference and strong performance in scientific algorithm programming. For applications where instant response matters, Muse Spark 1.1 can be the better option.

Frequently asked questions

Which model is better for scientific questions?

Claude Opus 5 scores 93.2 in the GPQA Diamond benchmark, which measures PhD-level scientific questions. Muse Spark 1.1 scores 89.8 in this measurement. For demanding scientific tasks, Claude Opus 5 is therefore more suitable.

Which model is faster?

Muse Spark 1.1 achieves a speed of 134.9 tokens per second, while Claude Opus 5 achieves 56.1. Time to first token is 1.59 seconds for Muse Spark 1.1, and 27.76 seconds for Claude Opus 5. Muse Spark 1.1 is therefore significantly faster.

Which model is cheaper?

Muse Spark 1.1 costs 2 USD per million tokens, while Claude Opus 5 costs 10 USD. Muse Spark 1.1 is thus five times cheaper, which may be decisive for budget-sensitive projects.
