Show HN: Needle: We Distilled Gemini Tool Calling into a 26M Model
- Dataset synthesized via Gemini with 15 tool categories (timers, messaging, navigation, smart home, etc.)
You can test it right now and finetune on your Mac/PC: https://github.com/cactus-compute/needle
The full writeup on the architecture is here: https://github.com/cactus-compute/needle/blob/main/docs/simp...
We found that the "no FFN" finding generalizes beyond function calling to any task where the model has access to external structured knowledge (RAG, tool use, retrieval-augmented generation). The model doesn't need to memorize facts in FFN weights if the facts are provided in the input. Experimental results to published.
While it beats FunctionGemma-270M, Qwen-0.6B, Granite-350M, LFM2.5-350M on single-shot function calling, those models have more scope/capacity and excel in conversational settings. We encourage you to test on your own tools via the playground and finetune accordingly.
This is part of our broader work on Cactus (https://github.com/cactus-compute/cactus), an inference engine built from scratch for mobile, wearables and custom hardware. We wrote about Cactus here previously: https://news.ycombinator.com/item?id=44524544

Launch HN: Cactus (YC X25) – AI inference on smartphones
Open source for the PR, then switching to non-open licensing is a cowardly, bullshit move.
https://github.com/cactus-compute/cactus/commit/b1b5650d1132...
Use open source and stick with it, or don't touch it at all, and tell any VC shitheels saying otherwise to pound sand.
If your business is so fragile or unoriginal that it can't survive being open source, then it will fail anyway. If you make it open source, embrace the ethos and build community, then your product or service will be stronger for it. If the big players clone your work, you get instant underdog credibility and notoriety.

Local-first software: You own your data, in spite of the cloud
Interesting to think about the concept of local-first in the age of AI.
Wanting to be able to run AI fully privately, and offline, is the reason we created Cactus:
