claude is much better than any of the others, gpt, gemini, deepseek, qwen, llama or whatever zuck called it. it has these things called "skills" and the CLAUDE.md file you get it to populate it with an analysis and example code for understanding the codebase, the skills, i have things like Go, typescript, react, svelte, elliptic curves, and others.
since adding skills for several things (i haven't added svelte, really need to) even just the typescript, yesterday i had massive progress on the ORLY web UI: https://relay.orly.dev/ - sign in using your browser signer to see it, you can search events, import/export your events (depending on permissions).
same with the other stuff, it works much faster when it has a cheat sheet, basically, and you update it and it functions like a memory for your project.
shakespeare is basically an open model, trained on nostr dev, that also forwards prompts to other models that alex set up, so it's actually a combination of several things plus his retrained model. so it's really good at flinging a mostly correct, novel nostr web app out.
