OpenAI’s ChatGPT is an AI system whose performance has been slightly tested and has achieved the most successful implementation utilizing Big Language Models (LLM).
Initially, the model used was GPT-3.5, which had some limitations. Nevertheless, OpenAI has already adopted GPT-4 to be integral to ChatGPT. This was done to improve the system’s ability to receive both text and picture inputs, among other beatifications of the system.
1. Copilot (Formerly Bing Chat)
The Microsoft-owned Copilot is the next idea on our list of GPT-4 windows. Not only does it integrate GPT-4 into the Bing search engine, but it is also for service availability. You are welcome to try Copilot manually at the address:

Best Free GPT-4 Access Option
Microsoft Copilot is the best free GPT-4-supported AI assistant option preferably. It comes with the maximum number of features, that is, 30 queries per session and advanced AI image generation, and yet a Microsoft account is all that is needed to set it up.
Meanwhile, Merlin is another superior choice for users who like browser extensions. Merlin allows you to switch between multiple LLMs. Although Sophistry AI is a good option for users looking for free GPT-4 access, image generation is only available after payment.
