Resin lets an agent build standalone LLM inference engines; vLLM and SGLang optimize DeepSeek kernels differently

AccBalanced · x · 2026-10-27

ekzhang1 unveiled Resin, a personal-project runtime for building fast LLM inference engines: it makes the generic parts reusable so an agent can write the model-specific forward pass and kernels for any architecture/hardware (GPU, TPU, AMD), yielding a standalone engine. In the same thread, helloericsf notes vLLM and SGLang both run DeepSeek's open kernels within a few percent of DeepInfer but took different paths — vLLM found the cost in experts (spreading them across more GPUs, balancing load), while SGLang focused on reducing memory traffic and kernel launches.
