Gemini 3.1 Pro in Google Antigravity: A Coding Disappointment

The Promises of Gemini 3.1 Pro

Google recently launched

within its
Google Antigravity
IDE, promising a leap forward in developer productivity. I decided to put these claims to the test using a series of
Laravel
projects. My history with this IDE hasn't been stellar, but a new model often signals a fresh start. Unfortunately, the gap between Google's marketing and the actual developer experience remains cavernous.

Performance and Skill Discovery

Testing began with a simple CRUD generation task. While

eventually delivered functional code, it did so at a glacial pace. It took six minutes to complete a task that
Claude 3.5 Sonnet
finishes in three. Interestingly, the model showed flashes of brilliance by discovering and activating specific skills like pest testing after I prompted it for its omission. However, the fact that it didn't proactively generate tests—a standard for models like
Claude 3.5 Opus
—highlights a lack of inherent coding intuition.

Technical Friction and Stability

The experience was marred by technical hurdles.

continues to suffer from random crashes and "terminated due to error" messages that force repeated restarts. Furthermore, the quota system is frustratingly opaque. I hit a usage wall after just nine minutes of work on a free plan, with no clear indication of how many tokens or requests I had left. This lack of transparency makes it difficult to justify a move to their paid tiers.

Final Verdict: Not Ready for Prime Time

Compared to the rapid iteration cycles of

or
OpenAI
, Google's progress feels sluggish. The IDE lacks robust support for custom Model Context Protocol (MCP) servers, limiting its extensibility for specialized frameworks. For now,
Gemini 3.1 Pro
is merely playing catch-up. If you value speed, stability, and a "test-first" mentality, stick with
Cursor
or
Claude
. Google is in the game, but they aren't winning it.
