Show HN: Calfkit – an SDK to build distributed, event-driven AI agents on Kafka I think agents should work like real teams, with independent, distinct roles, async communication, and the ability to onboard new teammates or tools without restructuring the whole org. I built backend systems at Yahoo and TikTok so event-driven agents felt obvious. But no agent SDKs were using this pattern, so I made Calfkit.

Calfkit breaks down agents into independent services (LLM inference, tools, and routing) that communicate asynchronously through Kafka. Agents, tool services, and downstream consumers can be deployed, added-to, removed, and scaled independently.

Check it out if this interests you! I’m curious to see what y’all think.

Show HN: Open-weight OCR got so cheap I had to share it

Show HN: Open-weight OCR got so cheap I had to share it This was not supposed to become a product.<p>When PaddleOCR-VL-1.6 dropped, independent benchmarks put it at the top of document parsing models. I had to try it. I needed a provider, but there simply isn&#x27;t one ready for production that I would trust.<p>So i set one up myself. I assumed that even after getting it running, serving a vision-language model would be expensive.<p>It turns out the opposite is true. Once I had it running properly, the cost was absurdly low. At proper GPU utilization, the cost is only around $1 per 1,000 pages.<p>The nearest competitors are either much lower quality (Azure Read) or absurdly expensive (Extend or Reducto). Even Mistral OCR 4 which is really good and pretty cheap is still 4x more expensive.<p>So I had to share it. I made the endpoitns public, and vibe-coded a simple dashboard.<p>Let me know what you think!
