 #### Features to Be Supported
 
-- **FP8 KV Cache**: While vLLM V1 introduces new FP8 kernels for model weight quantization, support for an FP8 key–value cache is not yet available. Users must continue using FP16 (or other supported precisions) for the KV cache.
-
 - **Structured Output Alternative Backends**: Structured output alternative backends (outlines, guidance) support is planned. V1 currently
   supports only the `xgrammar:no_fallback` mode, meaning that it will error out if the output schema is unsupported by xgrammar.
   Details about the structured outputs can be found
