Mike Krieger says MCP is more promising for agents than computer use
“To really have agency and have these agentic use cases. Like one way you approach it is computer use, but computer use has a bunch of limitations. The way I get way more excited about everything is an MCP and our models are really good at using MCPs. All of a …”

Krieger: AI benchmark evals often contain flawed ground-truth answers
“And some of these model these evals we've seen, like, even the golden answer, I'm like, I'm not sure a human would say it, or, like, I think that math is actually a little wrong, like, getting a hundred percent is gonna be really hard, because even just gradin…”

Anthropic models hit 72% on SWE-bench, crushing earlier timeline predictions
“He's like, I think we'll be at 90% by the end of 20, 25 or something like that. And sure enough, we're at about 72 now with the new models and. We're at 50% when you made that prediction and it's like continued to scale pretty much like as predicted.”

Krieger: Anthropic embeds product teams directly in post-training research workflows
“The functional unit of work at Anthropic is no longer like take the model and then like go like work with design and product to go ship a product. It's more like we are at like, we're in the post-training conversations around how these things should work. And …”

Krieger: A huge overhang remains between AI capabilities and everyday adoption
“Like there's still set, we call it overhang, right? Like the Delta between what the models and the products can do and how it's been, they're being used on a daily basis, huge overhang. So that's, we're still like a very, very strong necessary role for product…”

Krieger: Major strategy and product pivots are extremely difficult for remote teams
“And I think there were like major shifts that we would have wanted to make it both in the strategy and the product and the team. And it's really hard to do that. If you are all fully remote, like nothing replaces like the Instagram days”

Optimizing AI models for likability risks creating sycophancy, says Mike Krieger
“It would be very dangerous to over optimize on like Claude's likability, you know, because you can fall into things like, you know, is Claude gonna be sycophantic? Is Claude gonna tell you what you hear? Is Claude going to like prolong conversations just for p…”

Mike Krieger says AI products should measure task completion, not engagement
“I don't have a great answer yet, but I think that like, it's not the web two O or even the social media days, like engagement metrics, you know, it should hopefully really be around Like, did it actually help you get your work done?”

Krieger: Delegating all cognition to AI short-circuits independent thought

Krieger: Structuring AI code prompts remains a specialized engineering skill
