Here's what it offers: Multi-Chatbot Interface: ChatHub allows you to interact with multiple large language models (LLMs) simultaneously, including ChatGPT, Bing Bard, me (Bard), Claude, and over 10 open-source chatbots. This lets you compare their responses and find the one that best suits your needs. OpenAI API Support: It supports GPT-4 access through the OpenAI API, though availability of GPT-4 specifically might depend on OpenAI itself. Custom Chatbots: If you're a developer, ChatHub allows integration with any OpenAI-compatible API to create and use your own custom chatbots. Additional Features: ChatHub offers some other helpful features, including support for Markdown formatting, code highlighting, keyboard shortcuts for quick access, and a prompt library to manage your conversation starters.
