We tested 25 approaches to MCP tool search, including decision models, LLMs, and embeddings. Our benchmark runs 150 search queries against 536 tools. We settled on weighted BM25 with a few normalization rules. Fast, local, no model or API calls.

Pocket TTS has been getting updates those last few days. While it was ~100M parameters, we release smaller versions, down to 1.9M: an 18.2M model with the quality of the original, a 6.9M model, and a 1.9M model that runs 103x faster than real time on one...

DeepSeek is baking safety into the model at a deep level. I don't think it's just XinjiangQA.csv this time, and it's not a distillation artifact. Also, I see 1017 cheating *a lot*. After scaling up agentic RL, they must have become spooked. Frontier problems.
