Show HN: Core – open source memory graph for LLMs – shareable, user owned

I keep running in the same problem of each AI app “remembers” me in its own silo. ChatGPT knows my project details, Cursor forgets them, Claude starts from zero… so I end up re-explaining myself dozens of times a day across these apps.

2. Not relational – most memory systems store only the latest fact (“sticky notes”) with no history or provenance.

3. Not yours – your AI memory is sensitive f

Show HN: Arch-Router – 1.5B model for LLM routing by preferences, not benchmarks

Hi HN — we're the team behind Arch (https://github.com/katanemo/archgw), an open-source proxy for LLMs written in Rust. Today we're releasing Arch-Router (https://huggingface.co/katanemo/Arch-Router-1.5B), a 1.5B router model for preference-based routing, now integrated into the proxy. As teams integrate multiple LLMs - each with different strengths, styles, or cost/

Think of it as a spiritual successor to JS1k or the 4k demoscene — with a modern twist.

Would love feedback, ideas, or help spreading the word. And if you’v
