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 โ our proprietary Native Entropy Gating (NEG) technology.
With only 9 billion parameters and 1ร 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 % โ surpassing the published Qwen3.5-9B leaderboard score (81.7 %) by +2.64 %p.
๐ฌ What makes NEG different from Multi-Turn Iteration (MTI)?
Classical MTI needs 3-8ร 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 โ essentially free at inference time.
