Frequently asked questions

ElevenLabs FAQs

What is ElevenLabs used for?

ElevenLabs provides text-to-speech and voice cloning APIs. It is used for audiobook generation, voice agents, dubbing, and any application requiring high-quality synthetic speech.

How does ElevenLabs pricing work?

ElevenLabs charges per character of text converted to speech. Pricing varies by plan and model — Flash v2.5 is cheaper and faster, while Multilingual v2 offers higher quality.

Perplexity FAQs

What is Perplexity Sonar?

Sonar is Perplexity's family of search-augmented LLMs. Unlike standard LLMs, Sonar automatically searches the web and includes citations in every response. Sonar is available in standard and Pro (deep research) variants.

How much does Perplexity API cost?

Perplexity charges per 1M tokens plus a per-request fee for search operations. Check their pricing page for current rates as they vary by model and search depth.

When should I use Perplexity instead of GPT-4o?

Use Perplexity when your application needs real-time, verifiable information with citations — research tools, news summarisation, fact-checking, or any use case where accuracy on current events matters. For creative tasks, coding, or reasoning without web grounding, GPT-4o or Claude are better choices.
