Comparing Two Models on a Browser Task Benchmark
DhruvBatra_ · x · 2026-07-11
This post details the author's experience running yutoriai's browser-use benchmark using OpenAI GPT 5.6 Terra and Meta Muse Spark 1.1.
In terms of results, Terra delivered a "solid" performance with good token/step efficiency. Muse, on the other hand, frequently got stuck in loops and refused to execute checkout-related tasks due to safety triggers. Ultimately, Muse struggled near the 100-step limit and was deemed "unsuitable as a computer-use model."
