What is the context window of step-3.7-flash?
step-3.7-flash supports up to 262K tokens of context, with up to 256K output tokens per response. Some providers expose a smaller window; check the per-endpoint context column above.
How do I use step-3.7-flash 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 "step-3.7-flash" or any endpoint id from the table above. The quickstart section shows Python, JavaScript and cURL snippets.
Should I call step-3.7-flash by its managed id or a provider id?
Use the managed id, "step-3.7-flash". 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 "novita/stepfun/step-3.7-flash" only when you need one specific deployment and want no failover.
Route step-3.7-flash through one endpoint
