Proposed fix: [vLLM] ValueError "User-specified max_model_len (N) is greater than the derived max_model_len ... To allow overriding this maximum, set the env var VLLM_ALLOW_LONG_MAX_MODEL_LEN=1"
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Use a max_model_len within the derived limit, or configure proper rope scaling (e.g. hf-overrides) for the model; use VLLM_ALLOW_LONG_MAX_MODEL_LEN=1 only knowingly.
Option: Stay within the derived max or add rope scaling [evidence: official_recommended_action]
Applies when: Context extension attempts
Steps:
1. Lower --max-model-len
2. or supply rope scaling via --hf-overrides if the model supports it
Expected: Server starts with valid context length
