Capability
2 medium confidenceState-of-the-art among ~1B-active-parameter models at release (beats Gemma2, Llama2-13B-Chat, OLMo-7B, DeepSeekMoE-16B per the blog), but absolute capability is low-tier vs full-size 2026 chat models given the 1.3B active budget. Scored 2 on absolute capability. Exact per-competitor numbers live in arXiv 2409.02060 (blog charts are images), so the comparative claims are directional -- hence medium confidence.
