Gemini 2,5 performance: Great yesterday, terrible today

[danperks]

@vibe-qa The Max modes are tuned for very high-entropy changes, where it requires a lot of context and intelligence for the model to complete a task.

However, the Max mode is not a golden bullet, and unfortunately is just as likely (if not more in some cases!) to make mistakes, errors and output non-productive code suggestions.

See my quote from the announcement post here:

@danperks

This model is our best choice for implementing large and complex projects all at once or for completing intricate code edits that require a deep understanding of their functionality to maintain them.

But for standard code edits, Cursor’s agent is still the most cost-effective solution and would be more than enough for >90% of all the prompts Cursor sees.

We only recommend this model to those who can afford to test its capabilities without concern about the cost and will make use of its additional intelligence.
