openlit
Open source platform for AI Engineering: OpenTelemetry-native LLM Observability, GPU Monitoring, Guardrails, Evaluations, Prompt Management, Vault, Playground. 🚀💻 Integrates with 50+ LLM Providers, VectorDBs, Agent Frameworks and GPUs.
OpenLIT is an OpenTelemetry-native observability tool built for AI Engineering and LLM applications. It focuses on easy, vendor-neutral instrumentation for LLMs, vector databases, and other AI stack components. OpenLIT is ideal for teams already heavily invested in OpenTelemetry and GPU monitoring but offers fewer features for LLM prompt evaluation and experimentation.

Project mention: Representing Python notebooks as dataflow graphs | news.ycombinator.com | 2025-08-09
Even with data flow extension (also like ipyflow [0] ) I am still struggling with the execution model of notebooks in general. I often still see people defining functions and classes in notebooks to somehow handle prototyping loops.
I would love to see DAGs like in SSA form of compilers, that also supports loop operators. However, IMHO also the notebook interface needs to adjust for that (cell indentation ?). However, the strength of notebooks rather shows in document authoring like quarto, which IMHO mostly contradicts more complex controll flow.
