Server-Sent Events vs WebSockets for Token-by-Token LLM Generation
Evaluating HTTP/2 SSE transport overhead, backpressure management, and connection re-establishment in streaming AI user interfaces.
A technical publication exploring LLM token streaming, Server-Sent Events (SSE), Speculative Decoding, continuous batching, and low-latency neural pipelines.

Evaluating HTTP/2 SSE transport overhead, backpressure management, and connection re-establishment in streaming AI user interfaces.
How dynamic request insertion and virtual memory allocation for KV caches dramatically reduce Time-To-First-Token (TTFT).
Leveraging smaller draft models to predict sequence tokens in parallel with large parameter verification networks.
