Open-weight models lag behind hosted agents in new coding benchmark

A new benchmark, Muse Spark Open, has been released to evaluate open-weight models as coding agents. Initial tests show that many open-weight models, including Meta's Muse Spark Open, struggle to keep pace with hosted models on agentic coding tasks. While some models like Meta's Muse Spark Open and Xing 4.0 show promise on specific benchmarks like Terminal-Bench 2.1 and SWE-bench Verified respectively, they often fail in practical application on more complex tasks like the Forge 2.0 agentic coding build. AI

IMPACT Highlights the current limitations of open-weight models in complex coding tasks, suggesting a gap between theoretical performance and practical application.

    Muse Spark Open Benchmark: Open-Weight Models as Coding Agents

    <p>I asked for this review to come only from runs we already had, and in those runs none of the open models we ran this month kept up with the hosted ones as a coding agent. Meta's open-weights Muse Spark Open came out on 15 October with 816B parameters, 42B of them active. It's …
