What happened?

Using the following code with the thinking model. But cannot see the thought in the response.

from google import genai

# Initialize the Gemini client
client = genai.Client(api_key="YOUR_API_KEY", http_options={"api_version": "v1alpha"})

# Define the request configuration to include thoughts
config = {
    "thinking_config": {"include_thoughts": True}  # Enable thought process
}

# Send a request to the Gemini model
response = client.models.generate_content(
    model="gemini-2.0-flash-thinking-exp-01-21", 
    contents="Solve 3*x^3-5*x=1.",
    config=config
)

# Process and display the response, including thoughts
for part in response.candidates.content.parts:
    if hasattr(part, "thought") and part.thought:  # Check if 'thought' exists
        print(f"Model Thought Process:\n{part.text}\n")
    else:
        print(f"Model Final Response:\n{part.text}\n")

Hi, this is a known issue, the thinking model has been briefly removed from the API.

Update: The model is back in the Vertex AI API, but thoughts are disabled for the time being.
