Specialized Inference Engines Rise to Challenge vLLM and SGLang

As specialized inference engines proliferate, researchers including JiaZhihao argue that general systems like vLLM and SGLang cannot be optimal across all model-hardware-workload combinations, and coding agents now lower the cost of building specialized engines. A former SGLang author adds that the batch-of-independent-string-prompts abstraction may need to give way to declarative DSLs with inference built into operators.
