Could someone please share how such open source micro-LLMs might have been created? Do the creators take something like DeepSeek, and then delete most of the neurons to whittle down the size?

Technically, you could do that, but we trained this one from the ground up!

That sounds like an enormously expensive exercise.

Congrats on this release. The WASM implementation is really cool. This is a surprisingly good fit for a lot of cases, and I totally want to try turning this into a helper assistant for an application.

Please, though, take a pass at humanizing the text on the page. It's Clauded up all over and makes it hard to read.

Looking forward to npm version of needle-rs supporting v2. I added needle support for tool use in my side project.

thanks, give the playground a go and let us know how to improve!

I tried tweeking for structured extraction, but got issues with token budget. What is the context size?

At <50M parameters, training costs are completely trivial. You'll spend a lot more on your rent this month.

As someone who's done something similar (https://blog.lukesalamone.com/posts/creating-tiny-semantic-s...) the expensive part wasn't the training itself but the data curation and evaluation post-training. For this, getting a reasonable distribution of tool calls when the tool call can be anything isn't easy.

Once you have that, the model is small enough batch sizes are probably enormous and training can probably be done on a consumer-grade GPU in a week or less. Or even faster on a bigger GPU.

Any instructions available for running this on an ESP32-S3 or P4 like the site says?

Hey! Roman here from Cactus - yes, we're putting putting together a detailed guide for ESP32. In the meantime, if you have enough RAM for the current model (≈28MB), our repo will get you up & running: https://github.com/cactus-compute/needle
