Launch HN: Augento (YC W25) – Fine-tune your agents with reinforcement learning (ycombinator.com)
Hi HN, we’re the cofounders of Augento (https://augento.ai/). We’re building Deepseek R1-like fine-tuning as a service. You connect your agent, tell us when it’s right or wrong, and we deliver an LLM optimized for that agent.

I Built Faster Reinforcement Learning in C# Solo Than Teams Did with Python (rlmatrix.com)
The question comes relentlessly: “Why build reinforcement learning in C#?” Behind this query lies an unspoken assumption that serious machine learning happens exclusively in Python. This perspective reveals a fundamental disconnect between academic ML researchers with their sprawling Python scripts and those of us solving real industrial problems.

A (Long) Peek into Reinforcement Learning (lilianweng.github.io)
A couple of exciting news in Artificial Intelligence (AI) has just happened in recent years. AlphaGo defeated the best professional human player in the game of Go. Very soon the extended algorithm AlphaGo Zero beat AlphaGo by 100-0 without supervised learning on human knowledge. Top professional game players lost to the bot developed by OpenAI on DOTA2 1v1 competition. After knowing these, it is pretty hard not to be curious about the magic behind these algorithms — Reinforcement Learning (RL).

All Roads Lead to Likelihood: The Value of Reinforcement Learning in Fine-Tuning (arxiv.org)
From a first-principles perspective, it may seem odd that the strongest results in foundation model fine-tuning (FT) are achieved via a relatively complex, two-stage training procedure.

Using GRPO to Beat o1, o3-mini and R1 at “Temporal Clue” (openpipe.ai)
In this post we’ll discuss how we used Group Relative Policy Optimization (GRPO) to surpass R1, o1, o3-mini, and come within a couple percentage points of Sonnet 3.7 on a reasoning-heavy game called “temporal clue”, while being over 100x cheaper to run at inference time. We’ll include specific lessons learned about task design and hyperparameters we’ve found to work well. And finally, we share the training recipe we used to achieve these results, built on top of torchtune.

Deep Reinforcement Learning: Pong from Pixels (2016) (karpathy.github.io)
This is a long overdue blog post on Reinforcement Learning (RL). RL is hot! You may have noticed that computers can now automatically learn to play ATARI games (from raw game pixels!), they are beating world champions at Go, simulated quadrupeds are learning to run and leap, and robots are learning how to perform complex manipulation tasks that defy explicit programming.
