Error:400 The request's total referenced files bytes are too large to be read when analyzing large image (>20MB) with File API

[ChenChengKuan]

Description of the bug:

Hello I followed the official document of handling large image payload (>20MB) but still got the 400 invalid error with the code:

MODEL_NAME = gemini-2.0-flash-001
client = genai.Client(api_key="My api key)
my_file = client.files.upload(file='some_image.png')

client = genai.Client(api_key="My api key)
response = client.models.generate_content(
    model=MODEL_NAME, 
    contents=[
        'describe the image', 
        my_file
    ]
)

The error message:

ClientError: 400 INVALID_ARGUMENT. {'error': {'code': 400, 'message': "The request's total referenced files bytes are too large to be read", 'status': 'INVALID_ARGUMENT'}}

The file size is around 36MB. What I notice is that it is totally fine with image size >=20MB but below 30MB. It seems to me that 30MB is the limit, which is different from what official doc says that per file size can be as large as 2GB

Things I have checked

• client.file.list() only contain one file I upload which satisfies 20GB in total and 2GB / file
• genai python sdk version =1.3.0

Could you help me to resolve this?

Actual vs expected behavior:

Should not get 400 error

Any other information you'd like to share?

I am in the paid API tier not free plan

Hi @ChenChengKuan,

I checked from my end with images >=30mb, it is giving the same error with 2.0-flash models. I think there is some limit/issue with 2.0-flash models.

I checked with 1.5 models and "gemini-2.0-pro-exp-02-05" it's working fine.

According to me, you can change the model as of now.

I will follow up on this (2.0-flash) model with the internal team.

Thanks.
