FAQ
- Which is better, GPT-5 or Perplexity?
- On Multio, GPT-5's flagship GPT-5 offers a 400,000-token context window, while Perplexity's flagship Sonar Pro offers 200,000 tokens. GPT-5 tends to lead in multi-step reasoning, while Perplexity tends to lead in precision on code-heavy tasks. Run both on the same prompt in Multio to judge on your own use case.
- Can I use both GPT-5 and Perplexity on one account?
- Yes. On a paid Multio plan, both models are included and reachable through every Multio agent. BYOK is an optional add-on if you'd rather route premium-model usage to your own provider account. Free open-source models are included out of the box.
- How do I switch between GPT-5 and Perplexity mid-conversation?
- Multio lets you swap the underlying model in any chat without losing context — open the model picker above the input and pick GPT-5 or Sonar Pro.
- Is GPT-5 or Perplexity free on Multio?
- Free models are out of the box on Multio. Premium models like GPT-5 and Perplexity are BYOK — add your provider key in /settings/api-keys, and your provider bills you directly for usage.
