Frequently Asked Questions
How can I request new models to be benchmarked?
File an issue on their GitHub repository to suggest new models for testing.
How do you measure token speed?
They calculate Tokens Per Second (TPS) by timing how quickly models generate 20 output tokens after receiving ~1000 input tokens.
Is the raw test data available?
Yes, all benchmark data is stored in a public Google Cloud Storage bucket for transparency.
