5 specialized inference engines in a month: why fork the ecosystem when vLLM/SGLang can hit near-SOL?

- alexocheema asked why at least five specialized inference engines shipped in the past month, arguing AI can now generate passable engines quickly but ecosystem fragmentation is harmful.
- 0xishand weighed both sides: OSS engines like vLLM/SGLang can approach speed-of-light performance but require heavy knob-tuning because they're built general-purpose; serving a narrow model set with custom ops/kernels justifies a bespoke engine that avoids hundreds of code paths.
- He highlighted OpenInfer's modular scheduler: AI can stitch together the forward pass while you implement scheduling logic on top, yielding an engine that's easy to hack on and tune.
