AI observability can cost more than it should. We ran the numbers: same scale, same workload, four tools. At moderate production load, Logfire is up to 40x less expensive than the alternatives. Spans-based pricing. No proprietary units. AI native and full-stack observability in

Pydantic AI now has progressive disclosure. Capabilities load on demand: set `defer_loading=True` and the model pulls in its tools, instructions, and hooks only when it asks. Leaner context, lower token bill.

Your multi-agent workflow used to take 90s. Now it takes 4 minutes. No alerts. No slow downstream deps. Our final post of Infrastructure Week covers the new Metrics explorer in Logfire. No SQL required. Live now.

Your agent workflow times out on requests. The model is fine. So the slow thing is one of the 14 services it's calling. But which one? The new Services view in Pydantic Logfire takes you from the failing service to the exact trace that explains it: ordnl.link/PIog5LE

Your AI was fine last week. New prompt, new model, answers quietly got worse. Nothing errored. Sound familiar? Join us next Thu, Jun 25 for an online workshop on why AI observability should cover both the LLM layer and the whole system around it. Register:
