Ask Amit + AI Labs — AI-Native Portfolio
An AI-native developer portfolio that demonstrates AI rather than just describing it. The 'Ask Amit' assistant answers visitor questions about projects, blog posts, and résumé with cited sources, grounded in a 320-chunk RAG index built from the site's own content. A ⌘K command palette runs meaning-based search over the same index. A dedicated /ai-labs page bundles four interactive demos — RAG Playground, Prompt Cost Calculator, Embeddings Playground, and Tokenization Visualizer — each also embedded inline in the relevant blog post. Query embedding runs entirely in the visitor's browser via Transformers.js (all-MiniLM-L6-v2, q8); only the LLM call hits a rate-limited, key-protected OpenRouter route. The architecture keeps the Vercel serverless function tiny (no ONNX runtime bundled server-side) and the visitor experience snappy.
Built in public to learn something or prove a pattern. Some are published packages, some are demos that live on this site.
- ▸Bundling an embedding model server-side blew past Vercel's 250 MB function limit
- ▸Running RAG, semantic search, and LLM chat on a public portfolio without runaway cloud costs
- ▸Indexing scattered résumé, blog, and project data so a single assistant can answer about any of it
- ▸Moved query embedding into the visitor's browser via Transformers.js — the serverless function stays tiny and the first request after a cold start is no longer slow
- ▸Server-only OpenRouter key with per-IP rate limiting, length caps, and a hard spend cap on the key itself
- ▸Single 320-chunk RAG index built from blog posts, project data, and a lib/profile-data.ts source of truth — powers the chat assistant, the ⌘K palette, and the in-blog RAG demo
