# Needle2

51 Hacker News commenters recommended Needle2 and 22 criticized it, November 2025 to November 2026. It was recommended in 5 of 13 months. It meets the Hacker Approved badge rule.

**Verdict:** Tiny 26M-parameter model distilled from Gemini that converts simple instructions into tool calls on phones, wearables and embedded devices. Critics say it handles only simple, templated requests and reasons poorly.

## Why people recommend it

- Handles simple tool calls well (4 comments): "Using agent for simple tasks is inefficient and wasteful, Needle really resolves this." ([source](https://news.ycombinator.com/item?id=48118182)) "It seems to convert simple instructions to reasonable tool calls." ([source](https://news.ycombinator.com/item?id=49250181)) "it did a pretty good job for tool calling when I tried it" ([source](https://news.ycombinator.com/item?id=49249948))
- Small, cheap alternative to large agents (3 comments): "I like Needle a lot, and I love the idea of any tiny resource-thrifty LLM that can run on older hardware, that outputs only JSON!" ([source](https://news.ycombinator.com/item?id=49253792)) "they're incredibly cheap and handle NLP (not in a predictable way of course, but with great success rates)" ([source](https://news.ycombinator.com/item?id=49257433)) "this could be a nice model to have as the first pass in a more complex agent system" ([source](https://news.ycombinator.com/item?id=48116203))
- Runs on tiny embedded devices (3 comments): "This is a way that everyone can get that on the actual Apple Watch or local phone" ([source](https://news.ycombinator.com/item?id=48115948)) "being able to do that on a small embedded device is the novelty here" ([source](https://news.ycombinator.com/item?id=49252783)) "i made it run on esp32s3, and it works!!!" ([source](https://news.ycombinator.com/item?id=49370518))
- Fits Home Assistant use cases (2 comments): "This is pretty much exactly what I want for Home Assistant." ([source](https://news.ycombinator.com/item?id=48114828)) "This would be amazing for home assistant." ([source](https://news.ycombinator.com/item?id=48115524))

## What people warn about

- Weak reasoning and general knowledge (4 comments): "It seems to me that the model struggles to have enough general intelligence, knowledge, or reasoning capacity" ([source](https://news.ycombinator.com/item?id=49253543)) "I don't think consumers would consider this "intelligence". It's too dumb." ([source](https://news.ycombinator.com/item?id=49255428)) "models of this size can't reason about relative values very well" ([source](https://news.ycombinator.com/item?id=49263229))
- Fails outside a few templates (3 comments): "the web demo is not particularly impressive. It really doesn't like anything I throw at it." ([source](https://news.ycombinator.com/item?id=49250264)) "Since it seems limited to matching a few templates and otherwise falling flat on its face" ([source](https://news.ycombinator.com/item?id=49255484)) "limited to matching a few templates and otherwise falling flat on its face" ([source](https://news.ycombinator.com/item?id=49250779))
- Wrong or ignored tool arguments (2 comments): "to set the mode literally the opposite of what was requested." ([source](https://news.ycombinator.com/item?id=49256020)) "it just completely ignored the "brightness" parameter" ([source](https://news.ycombinator.com/item?id=49254464))
- Output quality often too low (3 comments): "if the number of cases where it works as expected is lower than what we could catch with a (old-Siri-style) heuristics based approach" ([source](https://news.ycombinator.com/item?id=49253881)) "Context definitely helps. But yeah the quality of it doesn't seem to be too high." ([source](https://news.ycombinator.com/item?id=48119704)) "Which is kind of a little way there but not useable on its own" ([source](https://news.ycombinator.com/item?id=48132122))
