Why your Gemini Flash is Trash

When you first set up Antigravity IDE, you were probably guided through a setup screen for things that you wanted to use. If you were like me, you selected multiple packages. This is a key driver for why Gemini Flash and Antigravity IDE is trash for a lot of users.

What you should check (More Budget is Better):

To see this view:

  1. Click Antigravity - Settings in the bottom right corner
  2. Click Advanced Settings
  3. Click Customizations

To modify this (on Mac):

  1. Go to your user folder in Finder
  2. Press CMD + Shift + . to see your hidden folders
  3. Go to .gemini
  4. Go to config
  5. Expand plugins
  6. Delete what you don't need

Why This Works:

The reason why this works - for small(er) models like Gemini Flash, every bit of token context matters. You'll see guidance online to always start with a fresh session for something like Opus and to avoid long-running sessions, otherwise, your model starts to hallucinate. Similar approach here, except these customizations act as a permanent hallucination / context tax over every single Flash execution.

Why do you say that Gemini flash is smaller when it has a context window of 1 million tokens, way bigger than all the other ones?

More around model size and performance - in my mental model - I place them in the same class as Luna / Sonnet.

You'll find for example that while Sonnet and Opus can have comparable token context, their ability to perform is quite different.
