Model limit probe

Perplexity: Sonar Deep Research | max output limit

Perplexity: Sonar Deep Research max output limit decides whether a key can enter a production route. TestKey reads model ID perplexity/sonar-deep-research, provider Perplexity, catalog context, real-key headers, 429 errors, and region signals together.

Why this limit matters

Perplexity: Sonar Deep Research max output limit decides whether a key can enter a production route. TestKey reads model ID perplexity/sonar-deep-research, provider Perplexity, catalog context, real-key headers, 429 errors, and region signals together.

Model: perplexity/sonar-deep-research
Provider: Perplexity
Limit dimension: max output limit

How to prove it

Read-only check. Detection data burns after 5 minutes.

Start with the visible signal: partial catalog signal, then read headers and error bodies with read-only requests.
max output limit must bind model ID perplexity/sonar-deep-research; limits from another model at the same provider cannot be reused.
