Mixture-of-Models router tops single LLMs on SWE-Bench Verified (75.6%)

A lightweight router that clusters tasks and selects the historically best model per cluster hit 75.6% on SWE-Bench Verified, narrowly outperforming top single-model baselines (~74%). Details and methodology are outlined in Nordlys Labs' write-up, including semantic clustering and per-cluster success routing without test-time search or repo execution [Nordlys Labs blog](https://nordlyslabs.com/blog/hypernova)[^1]. The open-source framework implementing this mixture-of-models approach is available here [Nordlys GitHub](https://github.com/Nordlys-Labs/nordlys)[^2]. [^1]: Adds: methodology, routing design, and reported benchmark results. [^2]: Adds: production-ready code for the router and integrations.

Mixture-of-Models routing tops single LLMs on SWE-Bench via task specialization

A lightweight Mixture-of-Models router that assigns issues to semantic clusters and routes to the historically strongest model per cluster hit 75.6% on SWE-Bench, edging past single-model baselines (~74%) by exploiting complementary strengths rather than defaulting to the top aggregate model [Reddit summary](https://www.reddit.com/r/LocalLLaMA/comments/1qvm0ft/mixtureofmodels_routing_beats_single_llms_on/)[^1]. The authors share a methodology write-up and an open-source framework so teams can reproduce the gating approach without test-time search or repo execution [methodology blog](https://nordlyslabs.com/blog/hypernova)[^2] and [framework code](https://github.com/Nordlys-Labs/nordlys)[^3]. [^1]: Highlights task-level specialization on SWE-Bench and the routing approach with reported results. [^2]: Details the clustering, per-model success statistics, and routing mechanism. [^3]: Provides the open-source implementation for building a MoM router.
