Open-Source AI Racing Harness
Hi I'm Dan from Elodin, making an open source real-time capable flight software simulation. For AI Grand Prix contestants, the wait for the Round 1 virtual qualifier simulation has been grueling. If you’re competing, check out our simulation harness to tide you over, built to match the published competition constraints and message format. It runs against real Betaflight, which we learned requires at least 1000 sensor samples per second to run real-time correctly. The competition warranted introducing a new feature to generate the camera sensor directly in the simulation loop. Typically…

In plain words
Open-Source AI Racing Harness is a real-time flight software simulation built by Elodin for AI Grand Prix competitors. It matches published competition constraints and message formats, running against real Betaflight firmware at the required 1000 sensor samples per second. The tool includes a built-in camera sensor generator that creates samples directly in the simulation loop, eliminating the need for external game engines like Unreal. Designed for teams preparing for the virtual qualifier, it offers a lightweight alternative to traditional heavy simulation setups.

From the sources
Today we're open-sourcing a practice rig for Anduril's AI Grand Prix (a $500K autonomous drone-race competition) so contestants and anyone else curious can start writing autopilot code against a working stack now, before the official Virtual Qualifier 1 simulator drops: github.com/elodin-sys/ai-grand-prix . It's open source, runs on macOS and Linux, and the whole setup is uv sync plus a 5-minute Betaflight build. (WSL should be workable too) The path here was longer than we expected. I came into this from the games side. One of my earlier jobs was working on The Sims 4, which (whatever else you think of it) does a serious amount of simulation under the hood: emergent behavior,…from elodin.systems

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
