An MCP codebase index for faster agent understanding and fewer full-file reads.
Source discussion: Harness engineering for self-improvement
“from a cost reduction standpoint, the two most outsized ROI wins came from making sure the agent runs all terminal commands in quiet and using a codebase index mcp to speed up understanding and reduce full file reads [0]. I've also found the latter also dramatically improved the quality of output.”

A tool for collecting human review feedback and iterating coding standards for automated review.
Source discussion: Harness engineering for self-improvement
“I've built and my team uses plannotator [1] for specs and code review. It stores all human annotated feedback, which we compile from time-to-time and iterate on coding standard skills for automated review (that seems to get better with the more feedback we provide).”

A small open reasoning-model family aimed at strong math and coding performance.
Source discussion: Show HN: Fine-tune an 8B model on a 4 GB laptop GPU
“If you are into small local models I highly recommend vibe thinker. It's a model trained specifically for reasoning. Basically a problem solver.”

A tabular foundation model for predictive tasks without prompting a general-purpose LLM.
Source discussion: Why Large Language Models Fail at Tabular Prediction
“TabPFN [1] is also working in this area and getting better and better. The inference time is still much worse than any of the more traditional models (xg/catboost etc).”

Source discussion: Why Large Language Models Fail at Tabular Prediction
“Google's TabFM [1] (and its previous TimesFM) seem the best approach so far on this area”
