Nanbeige Lab released Nanbeige4.2-3B, a compact agentic model built on a Looped Transformer architecture.
The model has 3B non-embedding parameters and the post claims strong agentic results, including 63.6 on SWE-Bench Verified and 46.9 on SWE-Bench Pro. The author says it outperforms larger Qwen3.5 and Gemma 4-class models on coding and daily workflow benchmarks when tested in OpenClaw with Lyzr Control Plane, while noting that the benchmark claims should be treated cautiously until independently verified. The release is pitched as a lightweight local personal assistant.
