Gemini 2.5 Pro unusable.md

Gemini 2.5 Pro unusable for coding?

Something really strange is going on with Gemini 2.5 Pro.

On one hand, it's supposedly the smartest coding model ever made. But on the other hand, I ask it to add one single parameter, and instead of a simple 2-line diff, it generates a 35-line one where it randomly changes logic, removes a time.sleep() from an API call pagination loop, and is generally just totally "drunk" about what I asked it to do. It's somehow both pedantic and drunk at the same time.

Every other model, even much smaller ones, can easily make the 2-line change and leave everything else alone.

I'm wondering how this thing beat the Aider leaderboard. Did something change since the launch?

Setting temp to 0.0 doesn't help either.

I share 4 generations, 2 with temp 0.0, 2 with the default 1.0.

Sonnet 3.7's answer is also included. Super clean, on to the point, easy to understand, only focusing on the change needed.

Gemini on the other hand:

Removes time.sleep()! - And even comments about it, or changes the value randomly.

It destroys my config by replacing it with a mock config.

It adds a whole if __name__ == '__main__':, even though this is a library file, it's not supposed to be run.

Random comments are added all around the file, random changes making no sense.

=> Gemini 2.5 Pro is super pedantic and drunk at the same time.

Here's the function to get details for a given thread in the GMail class:

def get_thread_details(self, thread_id: str, format: str = 'full', metadata_headers: list[str] = None) -> dict | None:
    """
    Get detailed information about a specific Gmail thread.

    Args:
        thread_id: The ID of the thread to retrieve.
        format: Amount of information to include. One of: 'full', 'metadata', 'minimal'.
               Default is 'full' for complete thread information.
        metadata_headers: When format is 'metadata', optional list of headers to include.

    Returns:
        A dictionary containing thread details or None if an error occurs.
    """
    try:
        kwargs = {
            'userId': 'me',
            'id': thread_id,
            'format': format
        }

        # Add metadataHeaders parameter if specified
        if metadata_headers:
            kwargs['metadataHeaders'] = metadata_headers

        thread = self.service.users().threads().get(**kwargs).execute()
        return thread
    except HttpError as error:
        print(f'An API error occurred while fetching thread {thread_id}: {error}')
        return None

This function:

• Takes a thread ID as required parameter
• Has optional parameters to specify the format ('full', 'metadata', or 'minimal')
• Allows specifying which headers to include when using 'metadata' format
• Returns the complete thread data as a dictionary with messages and their content
• Returns None if there's an error fetching the thread
• Handles API errors appropriately

You can call it like:

# Get full thread details
thread = gmail.get_thread_details('thread_id_here')

# Get only metadata with specific headers
thread = gmail.get_thread_details('thread_id_here', format='metadata',
                                 metadata_headers=['From', 'Subject'])

Now the diffs for all Gemini outputs, both temp 0.0 and temp 1.0

Also look for the time.sleep() parts. It's totally removed or changed to a random value.
