Why can AIs code for 1h but not 10h? A simple explanation: if there's a 10% chance of error per 10min step (say), the success rate is: 1h: 53% 4h: 8% 10h: 0.002% Toby Ord has tested this 'constant error rate' theory and shown it's a good fit for the data chance of

Why can AIs code for 1h but not 10h?

A simple explanation: if there's a 10% chance of error per 10min step (say), the success rate is:

1h: 53%
4h: 8%
10h: 0.002%

I'm pretty shocked by this from X - I report indisputable phishing, and get a "nothing wrong here" response. WTF are they doing?

x.com/pydantic/statu… The fact that pydantic is cutting new versions Friday at 11PM PT should tell you what you need to know about the team. getting. after. it.

I've added links to all our competitors that document how to integrate with Pydantic AI. I wonder if any other AI framework + Observability companies are confident enough in their product to do this? 👀 github.com/pydantic/pydan…

I'm chatting to Hugo Bowne-Anderson tomorrow about Human Seeded Evals and Pydantic Logfire on Youtube at 4pm UK. I'm pretty confident something like the think I'm describing here is where we'll end up with evals. Please join, I'd love to hear what you think. lu.ma/voeyx7n1

The Pydantic logfire backend, nothing is perfect, but I'm pretty convinced we have the right fundamental stack here. My guess is, if you removed the auto-generated TS from the counts, it would be pretty close to 1/3 .ts, 1/3 .py, 1/3 rs.

We shipped a ton of stuff in Q2 🚀 • Rebuilt Logfire's dashboard engine from scratch: way faster with new Standard Dashboards • Logfire MCP Server: ask your AI "any patterns in recent 404s?" in Cursor and watch it query your live logs & traces • PydanticAI at ~700k
