Open-source conversational AI agents for internal tools
Hey HN, We're John and Nadeesha. We created Inferable. [1] After years of working in operationally-intensive startups, we got tired of watching our internal tools gather dust and break. We've all been there - you build a tool, it works great for a while, then the API changes and suddenly you're back to square one. Sure, Retool and similar tools help, but someone still has to maintain them, and the backlog of "quick fixes" and the mountain of glue code keeps keeps growing.

In plain words
Inferable is an open-source platform that lets developers build conversational AI agents to manage internal tools and APIs. Instead of maintaining custom scripts or low-code platforms that require constant upkeep, teams can create AI agents that understand business needs and coordinate between existing systems. The agents integrate with Slack and email, reducing manual maintenance and API-related breakdowns common in operational tools.

Hey HN, We're John and Nadeesha. We created Inferable. [1] After years of working in operationally-intensive startups, we got tired of watching our internal tools gather dust and break. We've all been there - you build a tool, it works great for a while, then the API changes and suddenly you're back to square one. Sure, Retool and similar tools help, but someone still has to maintain them, and the backlog of "quick fixes" and the mountain of glue code keeps keeps growing. We started Inferable to see whether LLMs can help here. Inferable helps developers create conversational AI agents that act as the orchestration layer between existing internal APIs and human intent. Instead of building custom scripts or internal tools, developers can quickly set up these agents as conversational experiences [2]. We natively integrate with Slack and email (more coming), while also supporting Zapier and HTTP APIs for more advanced workflows. Our SDKs can wrap existing functions, or existing APIs (REST, GraphQL). We use long polling for message delivery, which means these instances don’t have to open ports / configure network ingress. A Re-Act agent dynamically searches through these tools based on user context, schedules jobs as tool calls, and iterates based on the result. We prioritize using existing codebases as deterministic guardrails. For additional verifications, we provide primitives to easily implement human-in-the-loop processes, custom authn, and authz, all backed with your existing codebases. Our customers use Inferable to: - Interact conversationally with internal APIs and databases (with restricted connections) - Programmatically process Datadog alerts - automatically tagging them and routing them with enriched context - Programatically or conversationally enrich Zendesk support tickets by automatically adding context from multiple internal systems To achieve this functionality, we've developed: - A built-in Re-Act (reasoning + action) agent - A distributed job queue for managing long-running tasks - End to end chat state, and message serialisation for tool calls - Service discovery and function registry for tools - Context-aware dynamic tool search - Native SDKs for Node.js, Golang, C#, and other languages We’re open-source (MIT) and fully self-hostable within existing infrastructure. Happy to receive any feedback or answer questions. --- [1] https://github.com/inferablehq/inferable [2] Acknowledging that calling an LLM every time is costlier than using a script, we’re solving the problem of repeating these flows without LLM intervention in our next iteration.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

- TITetris in a PDF▲1,289
I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…
