Section titled “Full transcript (original language)”00:00 Hey, as a developer, you find 500-plus models on OpenRouter. Now, Universal 3.5 Pro from AssemblyAI is one of them. To give you all some context, the biggest advantage of OpenRouter is now with one API key account plus billing, AssemblyAI models, and your existing models like OpenAI Claude, you could have all of them in OpenRouter in one billing, one API key. So, now all you need to do is you just choose the model as AssemblyAI
00:30 Universal 3.5 Pro with the API key you’ve already chosen from OpenRouter, and then you can give this information to your Claude. So, for example, all I did was gave Claude my OpenRouter key plus this endpoint, and it figured out built me this app called Scribe. And now in this app built on top of OpenRouter’s API key with AssemblyAI’s sync API model, you could actually give some key terms and context prompts, such as David with double A, you know, triple A. And
01:00 then you can give Priya with double E, or you can give a name like Ashworth, which most models, when you use speech-to-text, they say Ashworth. So, all these spellings are, you know, dependent on your context. And now, when you record the audio, David told me he’s unavailable, Priya told me she is available, and Ashworth is available as well. And then I’m just making a video. You hit stop, and using the OpenRouter key, you hit transcribe, and you will see the spellings of David, Priya with double E, Ashworth, it’s all
01:33 transcribed so accurately. And not just that, with OpenRouter’s LLM gateway, you can use this text audio route to any model with 500-plus models on OpenRouter, and you can build cool projects seamlessly. We can’t wait to see what you build with our API on OpenRouter. Thank you.
