});The current project already supports multiple AI LLM models such as OpenAI, Moonshot, Azure, g4f, Google Gemini, etc. to meet your different needs. If you want to introduce other AI LLM models, please fork this project and submit a Pull Request (PR) for us to evaluate and merge.
Before using this project, please make sure that you have applied for an API Key from the corresponding service provider. For example, if you plan to use GPT-4.0 or GPT-3.5, you need to make sure that you already have an API Key from OpenAI. In addition, you can also choose to use g4f, which is an open source library that provides free GPT usage services. Please note that although g4f is free, its service stability may fluctuate, and the usage experience may be good and bad from time to time. You can find its repository link on GitHub: https://github.com/xtekky/gpt4free.
In addition, as another option, you can apply for API services by visiting the Moonshot ai platform. After registration, you will immediately receive 15 of experience money, which is enough to support about 1,500 conversations. After successfully applying, you need to set the provider to moonshot and configure the corresponding apiKey to complete the project setup.
You need to configure apiKey, modelName and baseUrl. For azure ai, you also need to configure apiVersion.
openai: {
apiKey: 'xxxx',
modelName: 'gpt-4-turbo-preview',
baseUrl: 'https://api.openai.com/v1',

FFAIVideo by default integrates Microsoft Edge's online text-to-speech service. This service is not only powerful but also allows users to customize and set up their own application tokens, offering more flexible configuration and usage options. However, users in China may encounter access restrictions. For more details, please refer to this GitHub issue: rany2/edge-tts#290. To address this issue, we provide an alternative: you can use the Azure TTS service. This requires purchasing an Azure AI Speech service account. For more information, please visit: https://azure.microsoft.com/en-us/products/ai-services/ai-speech. When using the Azure TTS service, a configuration example is as follows:
azureTTSSettings: {
subscriptionKey: '*',
serviceRegion: '*',
},
Since FFAIVideo relies on FFmpeg for its functionality, it is essential that you install a standard, well-maintained version of FFmpeg. This will ensure that FFAIVideo operates smoothly and without any compatibility issues.
