We're thrilled to release Darwin-9B-NEG, a 9B-parameter reasoning model that embeds an architecturally-internalised sense of self-confidence directly into the transformer β our proprietary Native Entropy Gating (NEG) technology.
With only 9 billion parameters and 1Γ inference cost, Pure NEG jumps +12.63 %p over the same model without NEG. Going all-in with ensemble refinement pushes it to 84.34 % β surpassing the published Qwen3.5-9B leaderboard score (81.7 %) by +2.64 %p.
π¬ What makes NEG different from Multi-Turn Iteration (MTI)?
Classical MTI needs 3-8Γ extra inference passes. NEG instead lives INSIDE the single decoding loop. Two tiny modules ride with the transformer: NEG-Head predicts per-token entropy from the last hidden state, and NEG-Gate conditionally restricts the top-k choice when confidence is low. The gate activates in only 4.36 % of tokens β essentially free at inference time.

We've open-sourced a bilingual Semantic Highlighting model that can power multiple production scenarios:
1) RAG Answer Highlighting β Automatically highlight the exact sentences that answer user queries, improving interpretability and helping users quickly locate relevant information. 2) RAG Noise Filtering β Prune irrelevant context before sending to LLMs, achieving 70-80% token cost reduction while improving answer quality by letting the model focus on what matters. 3) Search System Highlighting β Add semantic highlighting features to recommendation systems, e-commerce search, or any retrieval system where users need to see why a result is relevant.
