That's simply shocking. Great work @antoine_chaffin

BrowseComp-Plus, perhaps the hardest popular deep research task, is now solved at nearly 90%... ... and all it took was a 150M model ✨ Thrilled to announce that Reason-ModernColBERT did it again and outperform all models (including models 54× bigger) on all metrics

I'm giving an Agentic Search workshop at the Applied ML Conference Apr 17-18
Definitely check it out, its quite a stacked schedule

@tmo_melonmaster @sentdefender They may have been negotiating with the Iranians for passage and that fell apart

@sentdefender They made a complete 180 of their position, what the hell happened? I’m not complaining, just very curious.

> Make indexing take half a day, not weeks
This was a big deal when I started at GitHub on code search. The old infra could not reindex in a month, and it was perennially on the edge of falling over and ever getting worse because the index kept growing.
My first week it had a split-brain scenario that the infra team had to rectify! Imagine having no GitHub code search for a month!

Content understanding IS query understanding
Better classify / organize your content. Understand queries better from user traffic

@burkov most jobs require writing skills but few of us are "writers" as a job
Even if the profession disappears, many jobs will need to understand compute in the same way we understand arithmetic + writing
English

This is the truth: modern agentic coder AI is better at everything compared to an entry-level coder.
**At everything.**
This means that hiring an entry-level coder doesn't make any practical sense, unless the organization wants to invest 5 to 10 years into someone learning to code by hand at a level of a mid- or senior-level coder (which is currently still needed to oversee agentic coders).
No leader in modern business would invest in an employee education for more than a quarter or, at the very least, a year.
No one.
Unless we reintroduce slavery, where the slave worker is required to stay with the employer who invested in their education until the debt is paid in full. Which is, of course, ridiculous to imagine, right?

@burkov Nobody should leave HS that isn't what we today would call a Junior developer

@burkov The answer is universal coding education that starts at a young age

@unclebobmartin Why does it have to be about Trump? Objectively we might have a bad strategy.
What we're doing now might just be an incompetent way of deterring / influencing Iran
