Show HN: Superserve – Firecracker microVM sandboxes for long-running AI agents

Hey HN, I built Superserve, a compute layer that lets AI agents live inside isolated Firecracker microVMs with no session time limits. The problem I kept running into: most sandbox providers kill your agent after 24 hours. If you're running something autonomous that needs to work for days — refactoring a codebase, running tests in a loop — you're constantly fighting timeouts and rebuilding state. Superserve lets you snapshot a running VM at any point, fork it into parallel branches, and resume e

Looking for feedback on my GPU-accelerated Snake AI project [P]

I've been building an AI that learns to play the classic Snake game through reinforcement learning. The goal is to reach high scores while keeping training time as low as possible. The current version averages 86 points (87 is the maximum) after less than 10 hours of training on a single free Google Colab T4 GPU. To keep training fast, it runs 4,096 Snake games directly on the GPU, combines GPU-native environment simulation with PPO + GAE, and uses a spatially-preserving CoordConv architecture that maintains the full game grid throughout training. I'm sure there's still room to improve. If you've worked on reinforcement learning or efficient training systems, what would you try next? Better exploration, reward design, network architecture, or something else? Repository: ( https://github.com/siddhartha399/PPO-CoordConv-Snake ) I'd really appreciate any feedback or criticism. submitted by /u/Due_Highlight_9341 [link] [留言]
