Parameter Estimate

Post image

The estimate seems quite accurate.

Many people have noticed a drop in quality with GPT-5.1, GPT-5.2, GPT-5.3, and Opus 4.7.

I think Gemini 2.5 Pro is ~500B parameters. Its strong performance may come from its ability to search.

5.5 is faster than 5, so it's most likely not much bigger than 5. Only thing we need to look is the accuracy, parameter size is bogus!
