Imagine having the power of advanced AI language models at your fingertips without breaking the bank. While most cutting-edge LLMs require a subscription, there’s a way to access them for pennies per query. Say goodbye to the $60/month price tag for Google Gemini, ChatGPT, and Claude.
Introducing Big AGI , the game-changing free public LLM chat interface. Not only does Big AGI allow you to use every major LLM via API key, eliminating fixed recurring fees, but it also boasts a powerful " beam " feature. This lets you query multiple LLMs simultaneously and fuse the results together, reminiscent of the old search engine aggregator Dogpile .
To embark on your AI research journey, create a developer/console account with the major LLM providers you want to explore. Then, generate your API keys (credit card required) using these links:
- Create OpenAI/ChatGPT API Key
- Create Anthropic/Claude API Key
- Create Google/Gemini API Key
- Create Perplexity API Key
Store your API keys securely, such as in a password manager’s secure note file. To avoid overspending, adjust the API provider settings to limit your expenditure to $10 per site or less.
Note: While it’s generally inadvisable to enter private API keys into third-party websites, Big AGI is an exception due to its reputation and security measures.
Armed with your API keys, visit the hosted Big AGI demo page . Click the settings gear icon in the bottom left, then click “manage AI models”. Add the service for each company you signed up with, and paste the corresponding API key.
