Not sure how accurate this is, but found contextarena benchmarks today when I had the same question. It appears only gemini has actual context == effective context from these. Although, I wasn't able to test this neither in gemini cli, nor antigravity with my pro subscription because, well, it appears nobody actually uses these tools at Google. https://contextarena.ai/?showLabels=false https://contextarena.ai/?showLabels=false
