jitllm Enables Mid-Inference Model Layer Migration Between GPUs
October 14, 2026
The jitllm inference engine allows moving model layers between different GPUs or hardware types (e.g., CUDA to Vulkan) mid-generation without re-prefilling the prompt. Moving Llama-3.2-3B between two T4 GPUs incurs only an 8ms pause and zero recomputed tokens.
