Ask HN: Why are Claude models so verbose?

Hello! First time poster, longtime reader. I’m a professional software engineer at a startup with about 50 engineers. My primary languages are Ruby (Rails), TypeScript (React), and Go.Of my colleagues, I’m one of the ones who tries to keep up with new AI models on every release. When there’s a new frontier or open-weight model, I’ll give it an honest try for a few days as my main driver and report back to my colleagues.I’m a Cursor user at work and in my side projects. My go-to models are GPT-5.

I estimate reading code costs 2.1x more than writing it

I hate reading agent-generated code and it's not a good use of my time, and I wanted a staistic to quantify by how much.My current estimate is $0.243 for a human to review one changed line and $0.114 in model spend for an agent to produce one benchmark-accepted changed line. That makes human review about 2.1 times as expensive under these assumptions.The agent calculation uses one public GPT-5.5 OpenHands run from May 2026. Its token categories, final patches, per-task costs, and evaluation

This is something I have been working on, on and off, for about a year but now I feel that it is stable enough to release. It really only has two tool sets, an execute tool for arbitrary code, and a bash tool, both of which run 100% in browser.As of now it's free and you can use your ChatGPT subscription or an OpenAI endpoint. There is an optional companion PWA that allows you to drive the extension from your phone and click captchas for it remotely, which I might charge for in the future.

Show HN: Use GLM-5.3 in Cursor today via tokengo API

Hi HN,Hearing a lot of buzz around GLM-5.3, which I expect to be the best open-source coding model with the weights dropping soon, I wanted to test it where I actually do my work.I just mapped GLM-5.3 to TokenGo so I could swap out the base URL and use it directly in my IDE.The backend handles the edge routing via Cloudflare to keep latency low, critical when you're waiting for inline code completions.If you want to try GLM-5.3 (or glm-5.3-flash) in your own workflow, here is the setup.For
