Fireworks adds video and audio inputs for Qwen3 Omni and Molmo2, and AWS S3 BYOB training data
Video & Audio Input Models
You can now query multimodal models with video and audio inputs for video captioning, scene analysis, and multimodal question answering. Deploy models like Qwen3 Omni and Molmo2 to process video and audio content directly using the Chat Completions API.
See the Video & Audio Inputs guide for deployment instructions and code examples.
AWS S3 Integration for Training Datasets
Training datasets can now be stored in your own AWS S3 buckets using GCP-to-AWS OIDC federation. This Bring Your Own Bucket (BYOB) approach keeps your data private while enabling secure access during Supervised Fine-Tuning and Reinforcement Fine-Tuning jobs—no long-lived credentials required.
See the Secure Training (BYOB) documentation for IAM role setup and usage examples.
Just-In-Time (JIT) User Provisioning for SSO (Enterprise)
JIT user provisioning automatically creates user accounts when users sign in through SSO for the first time. Enable this when configuring your identity provider to eliminate manual user creation.
See the SSO documentation for setup instructions.
