A batched, concurrent wrapper for OpenAI gym library

Hello HN, new user here, so please let me know if I break some rules. Currently I've been working on training reinforcement learning agents, and OpenAI gym, while is great, runs only one agent at a time. Hence I decided to extend it. I built a wrapper around OpenAI gym, such that it now runs several environments concurrently. All while (mostly) having the same call signature as OpenAI gym. And it is published to PyPI for anyone interested. For more details, please visit: https://github.com/Chimpan-Z/agymc Feedback really appreciated! Have a good day everyone!

In plain words

This is a Python wrapper for OpenAI Gym that enables concurrent execution of multiple reinforcement learning environments simultaneously. It maintains compatibility with OpenAI Gym's standard interface while allowing users to train agents in batches rather than sequentially. The tool is available on PyPI and targets machine learning researchers and practitioners working with reinforcement learning who need faster training across parallel environments.

    Echo – Fable-level results at 1/3 the cost using open-weight modelsJul 2026 · ▲484

    I’ve been building Echo (https://echo.tracerml.ai/), an experiment in making one AI system out of a pool of open-weight models rather than choosing a single model and using it for every task. It started with a simple experiment. I took a group of models, including GLM-5.2, Kimi K2.7 and others, and ran them on the same evaluations. Then I measured what would happen if, for each problem, you somehow knew in advance which models would be useful and how their outputs should be combined. That hypothetical system performed substantially better than any individual model in the pool.…

  • Terminal-Bench-RL: Training long-horizon terminal agents with RL2025 · github.com · ▲125

    After training calculator agent via RL, I really wanted to go bigger! So I built RL infrastructure for training long-horizon terminal/coding agents that scales from 2x A100s to 32x H100s (~$1M worth of compute!) Without any training, my 32B agent hit #19 on Terminal-Bench leaderboard, beating Stanford's Terminus-Qwen3-235B-A22! With training... well, too expensive, but I bet the results would be good! *What I did*: - Created a Claude Code-inspired agent (system msg + tools) - Built Docker-isolated GRPO training where each rollout gets its own container - Developed a multi-agent…

    Hey folks. Last year I was fortunate enough to sign a deal to write a book with my favorite technical publisher, The Pragmatic Bookshelf. When I started out as an Engineering Manager many years ago, I found that there wasn't a huge amount of material that specifically and practically helped me understand how to do my job. When you learn to program there's all of these amazing tutorials, examples and guides, but what was there for new managers? In response to this, a couple of years ago I started a blog over at https://www.theengineeringmanager.com which got a decent amount of…
