 - Multi-modal support: multi-modal support is only available through the AWS Neuron fork. This feature has not been upstreamed
     to vLLM main because NxD Inference currently relies on certain adaptations to the core vLLM logic to support this feature.
 - Multi-node support: distributed inference across multiple Trainium/Inferentia instances is only supported on the AWS Neuron fork. Refer
     to this [multi-node example](https://github.com/aws-neuron/upstreaming-to-vllm/tree/neuron-2.23-vllm-v0.7.2/examples/neuron/multi_node)

-- Known edge case bug in speculative decoding: An edge case failure may occur in speculative decoding when sequence length approaches
