Looking to narrow down your search results based on users’ locations?
We now support user location filtering, allowing you to retrieve results only from a particular user location.
Check out the guide.
You can now upload images to Sonar and use them as part of your multimodal search experience.
Give it a try by following our image upload guide:
https://docs.perplexity.ai/guides/image-guide
Looking to narrow down your search results to specific dates?
We now support date range filtering, allowing you to retrieve results only from a particular timeframe.
Check out the guide:

We’ve fully transitioned to our new pricing model: citation tokens are no longer charged.
If you were already using the search_context_size parameter, you’ve been on this model already.
This change makes pricing simpler and cheaper for everyone — with no downside.

We’ve removed all feature gating based on tiered spending. These were previously only available to users of Tier 3 and above.
That means every user now has access to all API capabilities, regardless of usage volume or spend. Rate limits are still applicable.
Whether you’re just getting started or scaling up, you get the full power of Sonar out of the box.
We’re excited to announce that structured outputs are now available to all Perplexity API users, regardless of tier level. Based on valuable feedback from our developer community, we’ve removed the previous Tier 3 requirement for this feature.
What’s available now:
- JSON structured outputs are supported across all models
- Both JSON and Regex structured outputs are supported for
sonarandsonar-reasoningmodels
Coming soon:
- Full Regex support for all models
This change allows developers to create more reliable and consistent applications from day one. We believe in empowering our community with the tools they need to succeed, and we’re committed to continuing to improve accessibility to our advanced features.
Thank you for your feedback—it helps us make Perplexity API better for everyone.
We’re excited to announce significant improvements to our Sonar models that deliver superior performance at lower costs. Our latest benchmark testing confirms that Sonar and Sonar Pro now outperform leading competitors while maintaining more affordable pricing.
Key updates include:
-
Three new search modes across most Sonar models:
- High: Maximum depth for complex queries
- Medium: Balanced approach for moderate complexity
- Low: Cost-efficient for straightforward queries (equivalent to current pricing)
-
Simplified billing structure:
- Transparent pricing for input/output tokens
- No charges for citation tokens in responses (except for Sonar Deep Research)
The current billing structure will be supported as the default option for 30 days (until April 18, 2025). During this period, the new search modes will be available as opt-in features.
Important Note: After April 18, 2025, Sonar Pro and Sonar Reasoning Pro will not return Citation tokens or number of search results in the usage field in the API response.
Please note that as of February 22, 2025, several models and model name aliases will no longer be accessible. The following model names will no longer be available via API:
llama-3.1-sonar-small-128k-online
llama-3.1-sonar-large-128k-online
llama-3.1-sonar-huge-128k-online
We recommend updating your applications to use our recently released Sonar or Sonar Pro models – you can learn more about them here. Thank you for being a Perplexity API user.
We are expanding API offerings with the most efficient and cost-effective search solutions available: Sonar and Sonar Pro.
Sonar gives you fast, straightforward answers
Sonar Pro tackles complex questions that need deeper research and provides more sources
Both models offer built-in citations, automated scaling of rate limits, and public access to advanced features like structured outputs and search domain filters. And don’t worry, we never train on your data. Your information stays yours.
You can learn more about our new APIs here - http://sonar.perplexity.ai/
We are excited to announce the public availability of citations in the Perplexity API. In addition, we have also increased our default rate limit for the sonar online models to 50 requests/min for all users.
Effective immediately, all API users will see citations returned as part of their requests by default. This is not a breaking change. The return_citations parameter will no longer have any effect.
If you have any questions or need assistance, feel free to reach out to our team at api@perplexity.ai

We’re excited to announce that pplx-api is now serving the latest open-source mixture-of-experts model, mixtral-8x7b-instruct, at the blazingly fast speed of inference you are accustomed to.
We’re excited to share two new PPLX models: pplx-7b-online and pplx-70b-online. These first-of-a-kind models are integrated with our in-house search technology for factual grounding. Read our blog post for more information!
https://blog.perplexity.ai/blog/introducing-pplx-online-llms
We’re also announcing general availability for our API. We’ve rolled out usage-based pricing, which enables us to gradually relax the rate limits on our models. Follow the updated steps for getting started.
We have removed support for replit-code-v1.5-3b and openhermes-2-mistral-7b. There are no immediate plans to add these models back. If you were a user who enjoyed openhermes-2-mistral-7b, try instead using our in-house models, pplx-7b-chat, pplx-70b-chat!
The Perplexity AI API is currently in beta release v0. Clients are not protected from backwards incompatible changes and cannot specify their desired API version. Examples of backwards incompatible changes include…
Removing support for a given model. Renaming a response field. Removing a response field. Adding a required request parameter. Backwards incompatible changes will be documented here.
Generally, the API is currently designed to be compatible with OpenAI client libraries. This means that, given the same request body, swapping the API base URL and adding your Perplexity API key will yield a response that can be parsed in the same way as the response OpenAI would yield, except for certain explicitly unsupported body parameters documented in the reference (link to reference).
