Summary analysis

Output Speed vs. Price

Output Speed: Output Tokens per Second; Price: Price: USD per 1M Tokens
Most attractive quadrant
Google
Output Speed: Tokens per second received while the model is generating tokens (ie. after first chunk has been received from the API).
Price: Price per token, represented as USD per million Tokens. Price is a blend of Input & Output token prices (3:1 ratio).
Median: Figures represent median (P50) measurement over the past 14 days.

Latency vs. Output Speed

Latency: Seconds to First Tokens Chunk Received; Output Speed: Output Tokens per Second
Most attractive quadrant
Size represents Price (USD per M Tokens)
Google
Output Speed: Tokens per second received while the model is generating tokens (ie. after first chunk has been received from the API).
Latency: Time to first token of tokens received, in seconds, after API request sent.
Price: Price per token, represented as USD per million Tokens. Price is a blend of Input & Output token prices (3:1 ratio).
Median: Figures represent median (P50) measurement over the past 14 days.

Pricing: Input and Output Prices

USD per 1M Tokens; Lower is better
Input price
Output price
Input price: Price per token included in the request/message sent to the API, represented as USD per million Tokens.
Output price: Price per token generated by the model (received from the API), represented as USD per million Tokens.

Speed

Measured by Output Speed (tokens per second)

Output Speed

Output Tokens per Second; Higher is better
Output Speed: Tokens per second received while the model is generating tokens (ie. after first chunk has been received from the API).
Median: Figures represent median (P50) measurement over the past 14 days.

Output Speed Variance

Output Tokens per Second; Results by percentile; Higher is better
Median, Other points represent 5th, 25th, 75th, 95th Percentiles respectively
