GPT‑6 Astra's real‑time driving capability is limited by latency and lack of open‑source low‑latency models
Problem
Large language models encounter high inference latency when used for real‑time vehicle control, preventing them from meeting the ~20 Hz control loop required for safe driving; additionally, the scarcity of open‑source low‑latency driving models hinders practical deployment.
Pain points
- High inference latency prevents real‑time control loops
- Scarcity of open‑source low‑latency driving models
- Performance gap between vision benchmarks and specialized systems
Questions to verify
- Have you encountered model latency causing control issues in real driving scenarios?
- Would you be willing to experiment with open‑source low‑latency driving models?
- To what extent do you think current autonomous driving systems need to close the vision benchmark gap?

Could a cloud-delivered LLM figure out how to drive this route, based on those input data and given access to those output actuators? Looks like yes. Sure.2) Could this work in the real world? Absolutely not. Three reasons: latency, latency, and latency. openpilot's driving model updates the target curvature and acceleration at 20Hz. Every millisecond of the round trip time through every piece of its entirely-local driving stack is well-understood, extremely consistent, and tightly optimized. It has to be, otherwise you can't react to even minor bumps or wind gusts, much less

The bitter lesson is finally coming for the self-driving cars. The vision stack, 3D maps, lane selection grammar, occupancy networks, it’s maybe all about to give way to a single GPT looking at camera feeds and predicting the next steering wheel adjustment. It’s mostly a latency problem at this point. The models are too big to run locally, but given that open-weight models like Qwen already exist, an open-weight, low latency equivalent to Astra can’t be too far out.
