The Ledger, every show

“Web observability stopped being a thing, not because the web stopped being a thing, but because all observability had to do web. If you were talking to people in 2010 or 2012, they would have talked about cloud observability. Now that's not a term because all …”

“I mean, in a hot loop, we can run, we can go from code to execution result in under a microsecond in like 800 nanoseconds. In reality, it's like single digit microseconds to run code or single digit microseconds to run the next step of a REPL or single digit m…”

“Even if you don't allow that Dino does not have any way of controlling memory. So even if someone can't run arbitrary code, they can oom your machine as often as they like.”

“OpenAI have got in touch with me, and basically, maybe I'm not supposed to say this, but basically said that Pydantic AI looks like what Swarms would become if it was production-ready.”

“I suspect Pedantic AI will be the first agent framework that implements those semantic attributes properly, because again, we control Pedantic AI, and we can say this is important for observability, whereas most of the other agent frameworks are not maintained…”

“If I want to go and register arbitrary tools, that's a whole different thing. And this thing breaks down, but often those tools are more and more, at least in enterprise, in packed up and put behind MCP servers.”

“We have plans to move some of the, basically store the data in rust types after validation. Not convert to Python types. So then if you were doing like validation and then serialization, you would never have to go via a Python type. We reckon that can give us …”

“I can't say which one, but one of the big foundational model companies, when they upgraded from Pydantic v one to v two, their number one internal metric of performance is time to first token That went down by 20%.”

“Pyodide, which is Python running inside the browser in Scripton, is supported now by Cloudflare. They just, they basically, they're having some struggles working out how to manage, ironically, dependencies that have binaries, in particular Pydantic”

“I think the truth is that everyone is centralizing around OpenAI's SD API as the one to do. So DeepSeek support that. Grok with a K support that. Olama also does it. Well, I mean, if there is that library right now, it's more or less the OpenAI SDK.”

“I suspect eventually most of those semantic, like that instrumentation of the big, of the SDKs will live, like I say, inside the main open telemetry repos.”

“CodePuppy is a coding agent built by an amazing guy called Michael Faffersberger at Walmart built with Pydantic AI. And it's got like, hasn't got very many stars. Hasn't got lots of like hype around it, but I don't know how much I'm allowed to say publicly, bu…”

“Monty has the TY type checker built into it. So before it will go and run any code, It's running type checking with these type stubs.”

“So I originally didn't implement JSON Schema inside Pydantic and then Sebastian, Sebastian Ramirez, FastAPI came along and like the first I ever heard of him was over a weekend. I got like 50 emails from him or 50 like emails as he was committing to Pydantic a…”
