Show HN: AI-utils.js – TypeScript-first lib for AI apps, chatbots, and agents (github.com)

I'm building LLM (and diffusion model) apps (and agents) and was not that happy with the existing libaries. Either they take away a lot of control (especially over the prompts) or they are just the raw APIs, e.g. OpenAI. So I wrote a lib that tries to cover the middle ground and provide additional functionality (e.g. type checking and LLM abstraction) while letting you fully control the prompts etc.
