Augmentoolkit 3.0

Finally a tool for training specialist LLMs. Fully open-source. Add documents and click a button. Augmentoolkit is a production-ready way to train AI subject matter experts. It lets you update an LLM's knowledge cutoff and put new facts into its brain, without any retrival needed. You can then do reinforcement learning to improve its performance in any task you can imagine. It includes: - Factual finetuning: A massive data pipeline which, given some documents, will automatically generate training data that teaches an LLM the facts inside. It also handles training for you. - Data generation…

Augmentoolkit 3.0 launched on June 15, 2025 with 7 votes, #3,918 of 7,999 launches that month. The site was still online in September 2026, 1 year on.

What it does

Augmentoolkit lets anyone make data and train custom AI to understand new facts or do new tasks. Usage is: add files, click button. By training custom LLMs you extend their knowledge cutoff. Combos with RAG. Can generate data for free on consumer hardware.

Create Custom LLMs. Contribute to e-p-armstrong/augmentoolkit development by creating an account on GitHub.

    Hi HN! We're Gabriel & Viraj, and we're excited to open source TensorZero. To be a little cheeky, TensorZero is an open-source platform that helps LLM applications graduate from API wrappers into defensible AI products. 1. Integrate our model gateway 2. Send metrics or feedback 3. Unlock compounding improvements in quality, cost, and latency It enables a data & learning flywheel for LLMs by unifying: • Inference: one API for all LLMs, with <1ms P99 overhead • Observability: inference & feedback → your database • Optimization: better prompts, models, inference strategies • Experimentation:…

    Hi everyone, we’re a small team, supported by Mozilla, who are working on re-imagining a UI for training, tuning and testing local LLMs. Everything is open source. If you’ve been training your own LLMs or have always wanted to, we’d love for you to play with the tool and give feedback on what the future development experience for LLM engineering could look like.

    Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https:&#x2F;&#x2F;jameshard.ing&#x2F;pilot&#x2F;globes&#x2F;all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

  • I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits&#x2F;month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
