A hands-on report instrumenting Sakana Fugu's OpenAI-compatible API with Langfuse, measuring how latency, token consumption, and TTFT change across Level 1–3 tasks.
A hands-on log comparing how the same weather tool call looks in Vercel's Eve agent framework when observed from the TUI versus the HTTP API, separating the developer-friendly display from the integration-friendly event stream.
I subscribed to Sakana Fugu to understand its nature as an OpenAI-compatible API and to plan how to observe its black-box cooperative reasoning from the outside.
An experiment log where I redact Flue 1.0 Beta observe events before sending them to Langfuse, tracking the issue triage workflow's runId, model, and results.
A hands-on comparison of two ways to send Eve tool-calling executions to Langfuse as trace/span/generation data.
A rough summary of how Flue thinks about harnesses, agents, workflows, skills, tools, sandboxes, and persistence — before actually running anything.
Using Cloudflare AI Gateway as an OpenAI-compatible endpoint, I walk through its logging, payload controls, metadata, cost estimation, and OTel integration to see how far it can serve as an entry point for LLM observability.
A short note on log design: clean success logs alone don't help you diagnose failures or improve recovery.
