How are you benefiting from prompt caching for simple classification?

Dumb but honest question - do repos like this buy stars? How do they have thousands of stars with very little presence across HN/Reddit/X?

Neolabs keep moving down the stack.

Neoclouds want to do neolab things and now chipmakers want to do neolab things

Re:GLM 5.2 and the coming AI margin collapse on Monday July 06, 2026 @08:42PM (#48812339)
Hard disagree.

Two LLMs with the same numbers on important benchmarks could have vastly different behavior in actual deployment. Not sure if as hard to switch as Excel <> Libre but still not "cheap and easy".

It's actually the perfect evergreen content to discuss on HN in an age where so much else is AI generated.

It's just an abstraction people are excited about at the moment. Langchain was an exciting abstraction at one point.

My bet is we converge on a super minimal model<>computer architecture.

True though pgvector is not deterministic in a strict sense since HNSW is probabilistic.

Same, it's in a similar vein as pgvector - probably not as performant as turbopuffer or chroma but you get the benefits of being in a really nice ecosystem.

Hi HN,Been hacking on a simple way to run agents entirely inside of a Postgres database, "an agent per row".Things you could build with this: * Your own agent orchestrator * A personal assistant with time travel * (more things I can't think of yet)Not quite there yet but thought I'd share it in its current state.

Re:1980s Farm Crisis on Saturday February 07, 2026 @07:27PM (#46929929)
Thought it was interesting to read about how farmers had to reskill as farming subsided as a common profession. In the context of the impact of AI on SWE.

And it's more important than ever in the age of coding agents.

Will this continue to be true? I do agree with the principle. But I've sometimes had the feeling that poor design upfront can have compounding consequences, especially when AI is filling in ambiguities.
Re:Show HN: A1 – Local Sandbox and JIT Compiler for AI Agents on Thursday November 27, 2025 @12:02PM (#46071103)
Simple idea - agents need fast JIT compilation to eliminate prompt injection attack vectors + maximize deterministic behavior.

Let us know what you think, thanks!

Re:What if you don't need MCP at all? on Sunday November 16, 2025 @09:30PM (#45950375)
If I may make a suggestion, many problems folks face with MCP would be solved if their agents were JIT compiled, not ran in a static while loop.

We've been developing this in case folks are interested: https://github.com/stanford-mast/a1
