DFQ is a ~1B parameter VLA that processes multi-camera, multi-timestamp images and acts as a policy for autonomous driving. It is built using NVIDIA's PhysicalAI-Autonomous-Vehicles dataset
Key components of DFQ VLA are:
- DinoV3 as vision encoder: Processes 16 images to output roughly 10k tokens
- Flex scene encoder encoder vision tokens into 900 scene tokens using joint self attention
- Qwen3-06.B LLM consumes vision tokens + trajectory history to produce 8 Meta actions
- Action chunking head consumes these meta actions + last hidden state of LLM to produce refined 64 xyz + 3x3 rotations
- SFT: in progress
- Behaviour tuning: ToDo
- Integration with AlpaSim: ToDo
- Checkpoints available on Hub: ToDo
