"We use Together.ai for the LLM backbone of our product (Llama 3.1 70B for chat). It is great. But the product also generates voiceover walkthroughs in 12 languages and Together.ai does not do TTS. So we added Gathos for the audio layer. One vendor for chat + image, one vendor for voice. The flat $18 on Gathos means voice generation is effectively free at our volume."
