The entry for Gemma 4 has several issues that should be addressed:

  1. Formatting: The line is missing the leading pipe (|), which breaks the markdown table rendering.
  2. Architecture Name: This table is for text-only generative models. The correct architecture name for the text-only version is Gemma4ForCausalLM. Gemma4ForConditionalGeneration is the multimodal variant and should be listed in the Multimodal Language Models section instead.
  3. LoRA Support: The implementation in vllm/model_executor/models/gemma4.py indicates that LoRA is supported (it inherits from SupportsLoRA). The LoRA column should be marked with ✅︎ to reflect this capability.
