How do I use fugu-ultra with the OpenAI SDK?
Install the OpenAI SDK, set base_url to "https://router.requesty.ai/v1", set your API key to your Requesty key, and set the model to "fugu-ultra" or any endpoint id from the table above. The quickstart section shows Python, JavaScript and cURL snippets.
Should I call fugu-ultra by its managed id or a provider id?
Use the managed id, "fugu-ultra". Requesty picks which of the 1 provider serves each request based on price and health, and fails over when one degrades, so the id keeps working while the routing changes underneath it. Send a provider id like "sakana/fugu-ultra" only when you need one specific deployment and want no failover.
