Trying to figure out how search works

Master Chief is proud of you

[Weaviate Podcast @weaviatepodcast]

Congratulations to @softwaredoug and @treygrainger! Their course on AI-Powered Search was highlighted in The Maven 100 list! 🔥

@MarcusForPeace Albeit this was peak dotcom era when everyone decided to major in CS

[Doug Turnbull @softwaredoug]

@MarcusForPeace To be fair, when I did CS in 1999 they said "look to your right, look to your left, 2/3 of you won't be here next year"

[Doug Turnbull @softwaredoug]

Not to brag, but I feel like my course with @treygrainger is simply phenomenal

We have both seen large search projects go wrong. And we know how to deliver incremental value in smaller, less sexy ways that actually work.

25% off this week :)

[Hamel Husain @HamelHusain]

Our evals course is 25% off this week! The next cohort will have completely refreshed material.

@sh_reya and I will cover new topics like: using agents for evals (w/o the foot guns), thinking like a data scientist, optimization approaches for harnesses and more.

My autoresearch talk from Haystack 2026

@bclavie I have the same experience, but its possible every expert in a field has this experience. Might not be retrieval specific :)

[Doug Turnbull @softwaredoug]

My buddy @hugobowne made me a pretty great animation to go with me showing off some autoresearch skills

@helloiamleonie @liquidai @maximelabonne @paulabartabajo_ Congrats!!

someone made a fork of opencode that routes through the unsecured ai endpoints from chipotle

[Doug Turnbull @softwaredoug]

Making a repo so GPT-5-mini can succeed isn't much different from one where a junior dev can't screw things up too badly

[Doug Turnbull @softwaredoug]

The more I do AI coding, the more I'm like, is this really any different than what I did before?

It doesn't matter whether I type the code or not

I spend so much time obsessing about test quality. About test speed. About good CI. About correctness, measuring performance, etc

[Doug Turnbull @softwaredoug]

One lovely thing about agents is when I'm editing in parallel and they decide to delete my edits with what they're off doing

I'll be talking about my autoresearch work on rankers at MICES in ~2 weeks. See you there!

[Doug Turnbull @softwaredoug]

@kmad @PrimeIntellect I'm curious - how do you avoid overfitting? I've been training retrievers for code generation, and straight up just using codex / claude seems to always overfit So I've built my own autoresearch coding agent to allow me to add validation checks + other guardrails

[Hugo Bowne-Anderson @hugobowne]

If you’re building AI-powered software, you’re building a retrieval system.

Why is a decades-old algorithm still relevant for agentic search?

Search legend @softwaredoug (led Search at Reddit and Shopify) breaks down why BM25 remains a key baseline for retrieval systems in 2026.

Check out the full segment where Doug shows us how autoresearch can power agentic search in comment 👇

I wonder why there isn't a thingie that routes really dumb simple fixes to like GPT5-mini. And routes "big sounding" things to GPT5 full?
