Create Run

Create a new run for an evaluation.

Model-based routing (for multi-account support):

• Pass model via header: x-litellm-model: gpt-4-account-1
• Pass model via query: ?model=gpt-4-account-1
• Pass model via body: {"model": "gpt-4-account-1"}
• Pass model via completion.model: {"completion": {"model": "gpt-4-account-1"}}

Example usage:

curl -X POST "http://localhost:4000/v1/evals/eval_123/runs"       -H "Authorization: Bearer your-key"       -H "Content-Type: application/json"       -d '{
    "data_source": {"type": "dataset", "dataset_id": "dataset_123"},
    "completion": {"model": "gpt-4", "temperature": 0.7}
  }'

Returns: Run object with id, status, timestamps, etc.
