Specialized inference engines: the batch-of-prompts abstraction may be wrong

sh_reya · x · 2026-09-17

shreya argues that with declarative DSLs and inference inside operators, OpenAI-API-style batches of independent string prompts may be the wrong intermediate representation. Key points: you can build specialized inference engines by reusing vLLM/SGLang components (model loader, forward pass); KV cache is the inference-era analog of the buffer pool, and domains like data processing will need specialized KV cache management; SGLang's original programming model was interesting here but its maintenance status is unclear.
