Perplexity API key; POST https://api.perplexity.ai/v1/agent (compatibility alias: /v1/responses). Set service_tier=default. auto or an omitted tier also selects default processing.
Perplexity Agent API default processing; USD per million tokens. Long-context rates apply by prompt length; the higher tier starts above 200,000 tokens. Tool calls are charged separately when used. Rates are host-specific, not the model developer’s direct-API prices. Unknown cache-write charges are not treated as zero. Cached input price: $0.20 / 1M tokens (base tier).

Interactions supports implicit caching only. For explicit caching, create a cache with the GenerateContent API and pass its name as cached_content.Source for How to enable it (opens in a new tab)
Reads use the cached-input rate. Explicit cache storage is billed per million tokens per hour, in addition to generation. Free-tier eligibility and audio rates vary by model.Source for Billing rules (opens in a new tab)
Limits & data boundaries
Cached content is a prompt prefix and counts toward the input limit. Implicit hits are not guaranteed. Explicit caching uses GenerateContent v1beta; API and model eligibility must match.Source for Limits & data boundaries (opens in a new tab)

What the measurements say
No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.
Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.
The record behind the model
Why it is included
Google-documented proprietary hosted release in the Gemini API model catalog. No public weights identified for this release in the reviewed documentation; public-weight Gemma models are excluded.
