• Volta refers to SM 7.0, Turing to SM 7.5, Ampere to SM 8.0/8.6, Ada to SM 8.9, and Hopper to SM 9.0.
• ✅︎ indicates that the quantization method is supported on the specified hardware.
• ❌ indicates that the quantization method is not supported on the specified hardware.

!!! note This compatibility chart is subject to change as vLLM continues to evolve and expand its support for different hardware platforms and quantization methods.
