Ship something, post it in #showcase. The best projects get featured in the gallery, the newsletter, and on our socials and qualify for bonus Gradium credits.

Ask a question about streaming, turn-taking, or a weird PCM mismatch and get an answer from someone who wrote the code, researchers or engineers.

Beta models land in the community first. Test them, tell us what breaks, and earn API credits for feedback that helps us improve the models.
