Perplexity
Perplexity’s lightweight web-grounded Sonar model for focused questions, with citations and a documented transition to the Agent API.
At a glance
API model ID: sonar
Capabilities & boundaries
Tool support requires the appropriate API integration; a supported tool is not automatically active in every chat.
The documented Sonar model is a non-reasoning search model. Do not treat its search-context size as a reasoning-effort level. During migration, check which Agent API configuration handles your request.
Put it to work
Original examples from EZ Ai Assist. Adapt these to your task and the features available in your workspace.
Workflow 01
Ask a narrow current question with dated primary evidence.
Find the official announcement and release notes for the product update named below. Report what launched, the announcement date, and any stated rollout limits. Cite the primary source for each point. Separate generally available features from previews and say when a detail cannot be confirmed.
Workflow 02
Prefer a short answer backed by authoritative documentation.
Explain the difference between these two technical terms using their official documentation. Give one practical example for each and cite the relevant definitions. Keep the answer under 250 words. If the terms vary by product or version, identify that scope instead of presenting one universal definition.
Workflow 03
Read the stated policy rather than infer eligibility.
Find the current official support-policy page for this software product. Extract supported versions, end-of-support dates, and the published upgrade path with source links. Note when the page was updated. Do not infer that a specific customer contract is covered by the public policy.

Common questions
Use Sonar-style search for a focused factual question or a concise topic update where cited web evidence matters more than exhaustive analysis. Keep the question bounded and check the sources; search-backed output can still be wrong.
Perplexity says Sonar Chat Completions support ended September 27, 2026. Synchronous and streaming calls continue through a gradual translation to Agent API requests; async Sonar calls are no longer supported. This does not establish whether EZ Ai Assist or a reseller exposes a particular model.
Perplexity maps Sonar to fast. Treat this as migration guidance, not an identical model or a guaranteed equivalent response. Recheck citations, quality, latency, and usage on representative tasks.
No. The published Sonar table adds request fees based on search-context size. The low, medium, and high rows are per 1,000 requests, not per million tokens.
No. Open the cited pages and confirm they support the exact claim, concern the correct version, and are recent enough. A citation is a starting point for verification, not a guarantee of accuracy.
The model card lists a 128K-token context. It does not establish a maximum output limit or training cutoff in the reviewed documentation. Integration limits may be lower, and search-backed answers still need checking.
No. The reference table describes Perplexity’s documented API billing. EZ Ai Assist plans are separate, and app availability must be checked in the workspace. These prompts are original starting points, not verified benchmark outputs.
