RWKV-LM
RWKV (pronounced RwaKuv) is an RNN with great LLM performance, which can also be directly trained like a GPT transformer (parallelizable). We are at RWKV-7 "Goose". So it's combining the best of RNN and transformer - great performance, linear time, constant space (no kv-cache), fast training, infinite ctx_len, and free sentence embedding.

- Java's Agentic Framework Boom is a Code Smell
Yes, Java SDKs are critical. But you don't need to rebuild entire orchestration engines just to write agents in Java. The ecosystem already has platforms solving the hard problems: memory (Zep, Mem0, LangMem), tools (specialized platforms), vectors (Pinecone, Weaviate, Qdrant), observability (LangSmith, Helicone, Langfuse). Integrate, don't rebuild.
- 10 open-source MCPs that make your AI agents smarter than your team lead
Helicone logs, monitors, and debugs your LLM calls
- Top Open Source Tools for LLM Observability in 2025
Helicone describes itself as an open-source LLM observability platform for developers and an all-in-one platform for monitoring, debugging, and improving production-ready LLM applications. It functions as a lightweight gateway or proxy, offering a clean interface to gain visibility into LLM API calls, making for easy integration. Helicone is best suited for API-level visibility rather than full-stack observability, which may limit insight in more complex agentic applications.

Hello dev community! 👋 I came across this great article by Helicone AI about automating Product Hunt launches. They recently just received #1 Product of the Day, and thought I'd share the key takeaways:
- Show HN: Monitoring your OpenAI usage without a third party
I'm sorry, I should have been clearer -- I meant that I wish this would be a locally self-hostable observability solution for OpenAI-compatible APIs in general, not something that can only be deployed to Azure and is tied specifically to Azure's OpenAI service.
For example, Helicone[0] and llm.report[1] work as generic proxies for the OpenAI API and you can deploy them anywhere.
