When does this happen?
IF When using Claude-3.7 Sonnet model with thinking parameter through litellm_proxy, the request fails with UnsupportedParamsError if the model name includes the 'litellm_proxy/' prefix.
How others solved it
THEN Remove the 'litellm_proxy/' prefix from the model name when using the proxy base URL, or set `litellm.drop_params=True` in your code or `drop_params: true` in the proxy config. Additionally, when thinking is enabled, ensure `budget_tokens` is at least 1024 and `temperature` is set to 1.
response = litellm.completion(
api_key="sk-************",
base_url="http://localhost:4000",
model='claude-3-7-sonnet-20250219',
messages=[{"role": "user", "content": "How can I solve world hunger?"}],
max_tokens=2001,
temperature=1,
thinking={
"type": "enabled",
"budget_tokens": 2000
}
