This isn't intended to be comprehensive. These are the ones that I think are worth mentioning. I've tried all of them except the hosted stable diffusion apis. * OpenAI's GPT-4, GPT-3.5 * Transcription: Whisper, AssemblyAI, Google Cloud transcription, Deepgram * Hosted Stable Diffusion APIs, as well as self-hosted Stable Diffusion * No Midjourney API :( * Vocode.dev for voice chat tools * Elevenlabs for voice generation * D-ID for animating images into videos
