Metis-1.6 technical report: tiny MoE hits near-top math scores at 2.36B active params

Lernex · hf · 2026-11-02

Lernex published the Metis-1.6 technical report describing small, efficient mixture-of-experts LMs trained on limited data. The Logos variant scores 65.83 (2nd of 30 models) across 11 math benchmarks — just behind Gemma 4 12B's 68.60 — while activating only 2.36B parameters per token and training on just 1.02T tokens, versus 7.7T+ for rivals that disclose counts. Both Metis models sit on the compute Pareto frontier against 28 open models, Logos also on the data frontier, despite acknowledged training errors and architectural issues.
