Are Webhook Callbacks for Generation Completion Planned in the API Roadmap?

Hi Max, Quick question on the API roadmap: any plans to support webhooks for generation completion callbacks? Use case: I'm building a healthcare app that generates patient visit summaries via your API. Currently running into the polling constraint with serverless functions (150s timeout vs. 1-5 min generation time), which forces me to maintain separate polling infrastructure. A simple webhook callback when status: "completed" would let me handle everything in a single async flow: POST /generations { ..., callback_url: "https://myapp.com/gamma-complete" } Is this on the roadmap? Thanks!
