Automatically switch from GPT-4o to GPT-4o mini

When the GPT-4o model reaches the usage limit for non-ChatGPT Plus users, could it be considered to switch to the 4o mini model? Alternatively, replace the ChatGPT 3.5 model in the model list with the ChatGPT 4o mini model. This plugin is a great plugin, thank you for your work.

firefox version

please bring a firefox version

How to use my openai api key?

It is very easy to reach the limit with the current GPT-4o. Is there any way to input my own key?

希望加入API功能

no support local model

Login Required despite already being logged in

I installed chrome extension, choose GPT-4o to use, but I'm getting a (Login Required) next to the GPT-4o icon in the lower left:

I'm already logged into chatgpt in the same browser. There is no option to login anywhere in the extension or in extension settings.

3rd party error for all Llama

been getting below error for all Llama models. I am not sure if signing into perplexity helps

BTW very thanks for this extension.. extremely helpful!

Typo in directory name: "porvider" should be "provider"

The directory name "porvider" is misspelled and should be corrected to "provider." This typo affects all references to this directory in the codebase. All instances need to be updated accordingly.

seems typo on home page "Geminni" -> "Gemini"

- Fast access to popular AI models like GPT-3.5, GPT-4, GPT-4o,Claude, Llama, Geminni,and Kimi, etc.

where "Geminni" should be "Gemini".

add model

Could you please include more models that Chinese users can directly use, such as Ernie Bot and Tongyi Qianwen?
