Gemini 3 input token exceed 1 million token

Hi, i am using Gemini 3 Model series. Yesterday, it was all working fine. But today i am getting input token exceed 1 million token. My input is roughly 300k token, but Gemini 3 just throw errors of exceeding 1 million token.

Can we advise on how to proceed? Thanks!

p.s. I am attaching documents ( 200k token) and also have file search tool enabled

Here is the usage data, it is not at 1 million token.
