Levi – run AlphaEvolve on your Claude Code/Codex for dirt cheap
Hi HN, Wanted to share something I'm excited about. I’ve been fascinated by AlphaEvolve and its results for more than a year now, but using open source frameworks seems overwhelming because of the high costs. I can’t really afford hundreds of Claude Opus calls every time I want to run it. I want to be able to try it out many times and all sorts of unique domains. What if it was possible for AlphaEvolve to be much more affordable while getting a better performance? . Over the last six months or so, I’ve been working on LEVI, an open source AlphaEvolve-like system that can outperform existing…
What it does
In the maker’s words, at launch
Hi HN, Wanted to share something I'm excited about. I’ve been fascinated by AlphaEvolve and its results for more than a year now, but using open source frameworks seems overwhelming because of the high costs. I can’t really afford hundreds of Claude Opus calls every time I want to run it. I want to be able to try it out many times and all sorts of unique domains. What if it was possible for AlphaEvolve to be much more affordable while getting a better performance? . Over the last six months or so, I’ve been working on LEVI, an open source AlphaEvolve-like system that can outperform existing open source frameworks at a fraction of the cost (upto 35x cheaper!). It can also run on Claude Code or Codex, making it even more accessible (I've mostly been using it with a QWEN-30B). LEVI comes in two flavors where I felt it’ll make the most difference: Code Optimization, and Prompt Optimization (sorry math, you got a less direct path; workable through the code route). The core thesis behind LEVI is that with the right search architecture, smaller models can substitute for or outperform larger ones. This means it’s much more economical to rely on smaller models for most of the work. That’s the entire takeaway. Making this work in practice is a different problem, but if you forget everything else from this post this is the only message I think I’m really trying to convey here. LEVI does it in three ways: 1) Invest in solution diversity from the start and ensure its maintained. We don’t want to converge to the same solution, especially with smaller models in the mix, and rely on large models to pull us out of the basin. 2) Use smarter routing across larger and smaller models (i.e. most mutations don’t require a Claude Opus X) 3) For prompt optimization not every rollout is as important. Build a proxy subset to approximate. I’ve tried LEVI on systems problems (like MoE scheduling or database transaction scheduling) and found that LEVI outperforms existing frameworks on almost every problem I threw at it while consistently using a smaller budget (unto 7x cheaper). For prompt optimization, across problems like IFBench and HotSpotQA, LEVI reaches a similar or better score as GEPA while using less than half the rollouts! Happy to answer any questions or take any suggestions! If there are unexpected or niche domains where this can be applied, I would love to hear.

Saw the remotion claude skills launch earlier, and honestly even though I was surprised how decent some of the results turned out to be I ended up never trying it out with claude code because I knew I'd have to setup remotion, bundler etc and if I was already doing it once I thought I might as well turn it into a site where anyone could just write messages and get a video without any prerequisites. I also know Claude Code is not something everyone has and setting up remotion is a pain. And one of the biggest lessons I learned from this whole experience is that Opus is actually not that good…

Hola HN! Long time lurker, sometimes commentor, first time poster here. I’ve been working alongside my two co-founders and a few colleagues on a project I’m excited (and a little nervous) to share with you all! Like many of us, I’ve lived a tortured existence with AI coding (is it vibes?) over the past few months - I think November was a big moment with this. But, one thing I’ve noticed after building orchestration layer after orchestration layer is that the thing I always came back to was “what the hell is Claude Code actually doing?” Perhaps it’s because of the time Claude Code got…
- ECEnable Claude to interactively debug your code2025 · github.com · ▲7
I participated in the Nvidia + Vercel 2 hour hackathon in SF tonight, and built something I've wanted, but hadn't tried building. I implemented an MCP Server and VS Code extension to allow Claude Desktop to place breakpoints, step through code, and execute expressions (assuming language support). So you can ask it a question that requires actually stepping through the code and now it can actually do that - check values for you, etc. It's _definitely_ not perfect. Have improvements? Please make a PR!
- OOOpenClawdex – Open-Source Orchestrator UI for Claude Code and CodexApr 2026 · github.com · ▲7
One coding agent orchestrator UI for Claude and Codex, but actually feels nice. Free, open-source, MIT licensed. Why I built it: - I wanted a lightweight UI as nice as the Codex app, but without the complexity and the custom diffs on the side - I want files and diffs open straight in my editor! - And I wanted both agents - Anthropic + OpenAI — in one place How it works: - No API keys, no OAuth, no separate billing — it just uses whatever you're already logged into. So your Claude Max and ChatGPT/Codex subscriptions both work out of the box. - Talks to Claude Code via the Claude Agent…
- ITI tried to reverse engineer Claude Code usage limitsMar 2026 · github.com · ▲5
I hit my Claude Code usage limit yesterday in the middle of regular work. Not doing anything unusual - just a couple of coding sessions. It felt like it came out of nowhere. Then today Anthropic announced they're tightening 5-hour limits during peak hours. It feels like a rug pull is coming and we're all just supposed to accept "you've used too much" with no explanation of what "too much" means. Usage limits have always been opaque. A vague percentage bar. No dollar figure. No formula. No way to plan your work around it. So I built a proxy that captures the rate-limit headers Anthropic sends…

Firstly, I’m not a developer — but I am a very technical, over-50, product person and entrepreneur. This project started shortly after Claude Code launched. I had already worked on a few other AI coding projects, and decided to see how far I could realistically take something end-to-end. While I had some help from a developer, I increasingly felt capable of taking on more work myself. So about 9 months in the making, working full time on it past 2 months. Stack: Postgres, Next.js on Render. Monorepo with both frontend and backend services. Some takeaways from using Claude Code on this…
