Reference workload examples
Each example is pure arithmetic from this committed record's input and output token prices. The assumptions are shown inline.
| Example | Assumed monthly tokens | Estimated token cost |
|---|---|---|
| Light reference | 1M input + 250K output tokens/month | $4.00 / month |
| Production reference | 10M input + 2.5M output tokens/month | $40.00 / month |
| Heavy reference | 100M input + 25M output tokens/month | $400 / month |
Examples exclude taxes, discounts, commitments, gateway fees, cache effects, and non-token charges unless those charges are part of the committed token price record.
When this model is cost-effective
Sonar Deep Research ranks 3 of 4 Perplexity records by combined list price ($10.00 for 1M input plus 1M output tokens). That puts it in the middle third of this provider's committed records.
Cached input reads are listed at $2.00 per 1M tokens, 100% of the fresh input rate, so repeated cached prompts have a lower committed input-token cost than fresh prompts.
No context window is committed for this record, so there is no long-context cost signal to apply.
Cheaper alternatives
These records have a lower committed input+output list price than this page's record. Same-provider records and same-model cross-provider records are preferred when available.
