+!!! info "About `--eval-model` and `--eval-provider`"
+    The `--eval-model` option specifies a separate model for the evaluation, assessment, and feedback summarization agents. The `--eval-provider` option allows specifying a different provider for the evaluation model. This is useful for:
 
-    - **Model benchmarking**: Use a consistent evaluator (e.g., `qwen/qwen3-235b-a22b`) across different annotation models for fair comparison
+    - **Model benchmarking**: Use a consistent evaluator (e.g., `qwen/qwen3-235b-a22b-2507` via Cerebras) across different annotation models for fair comparison
     - **Cost optimization**: Use a cheaper model for annotation and a more capable model for quality assessment
+    - **Speed optimization**: Use a fast provider like Cerebras for the evaluation model
 
-    When not specified, all agents use the same model as `--model`.
+    When not specified, all agents use the same model and provider as `--model` and `--provider`.
