Ask HN: Good resources for shipping AI products?

We're building an AI tool for backdrop build and want to ship in 4 weeks. We were hoping the community could share good resources you've come across for building out an AI product from 0 to 1.

We're looking for boilerplate code like Vercel AI templates and good practices for RAG (like the blog from Anyscale), prompt tips, etc. Basically a guidebook for hacking together an AI tool, optimizing for launching and experimenting quickly.

Any resources are appreciated!
