The free tier grants instant access to GPT-3.5 Turbo, Gemini 1.5 Flash, and Perplexity Experimental models.
Every registered user can run unlimited chats at no cost, with GPT-3.5 Turbo (OpenAI) as the default model for general reasoning and fast Q&A.
Gemini 1.5 Flash (Google) is included for high-speed, large-context prompts, and Perplexity Experimental offers concise research and real-time web search tailored for trending questions.
Model selection is always one click away—users can toggle between engines per prompt or mid-conversation to compare outputs.
The free tier includes web search and rapid research, but file uploads and latest models require Pro.
