Context Window: Solar Pro 2 (Reasoning) Providers

Context Window: Tokens Limit; Higher is better

Context window: Maximum number of combined input & output tokens. Output tokens commonly have a significantly lower limit (varied by model).

Variance between providers: While models have their own context window, in cases this is limited by providers.

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

Output Speed: Solar Pro 2 (Reasoning) Providers

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 for models which support streaming).

Median: Figures represent median (P50) measurement over the past 72 hours to reflect sustained changes in performance.

Output Speed Variance: Solar Pro 2 (Reasoning) Providers

Output Tokens per Second; Results by percentile; Higher is better; 1,000 Input Tokens

Median: Figures represent median (P50) measurement over the past 72 hours to reflect sustained changes in performance.

Latency

Measured by Time (seconds) to First Token

Time to First Answer Token

Seconds to First Token Received; Lower is better

'Thinking' time (reasoning models, where applicable)

Input processing time

Time To First Answer Token: Time to first answer token received, in seconds, after API request sent. For reasoning models, this includes the 'thinking' time of the model before providing an answer. For models which do not support streaming, this represents time to receive the completion.

Median: Figures represent median (P50) measurement over the past 72 hours to reflect sustained changes in performance.

Time to First Token: Solar Pro 2 (Reasoning) Providers

Seconds to First Token Received; Lower is better; 1,000 Input Tokens

Latency (Time to First Token): Time to first token received, in seconds, after API request sent. For reasoning models which share reasoning tokens, this will be the first reasoning token. For models which do not support streaming, this represents time to receive the completion.

Median: Figures represent median (P50) measurement over the past 72 hours to reflect sustained changes in performance.

Time to First Token Variance: Solar Pro 2 (Reasoning) Providers

Median: Figures represent median (P50) measurement over the past 72 hours to reflect sustained changes in performance.

End-to-End Response Time

Seconds to output 500 Tokens, calculated based on time to first token, 'thinking' time for reasoning models, and output speed

End-to-End Response Time: Solar Pro 2 (Reasoning) Providers

Seconds to Output 500 Tokens, including reasoning model 'thinking' time; Lower is better; 1,000 Input Tokens

'Thinking' time (reasoning models)

Input processing time

Outputting time

End-to-End Response Time: Seconds to receive a 500 token response. Key components:

Input time: Time to receive the first response token
Thinking time (only for reasoning models): Time reasoning models spend outputting tokens to reason prior to providing an answer. Amount of tokens based on the average reasoning tokens across a diverse set of 60 prompts (methodology details).
Answer time: Time to generate 500 output tokens, based on output speed

Standardized Reasoning Tokens: For fair comparison, the number of reasoning tokens is standardized across all providers for each model based on the model's representative query token counts.

Median: Figures represent median (P50) measurement over the past 72 hours to reflect sustained changes in performance.
