Hedra — Developer Documentation & Integration
Hedra exposes its capabilities through a REST API, giving developers programmatic access to inference, fine-tuning, and GPU sandbox environments. Key integration points:
- API access: Available across all paid tiers; enables inference calls against 100+ models including Hedra's proprietary frontier visual models.
- Fine-tuning endpoints: Trigger and manage fine-tuning jobs with reinforcement learning for task-specific objectives directly via API.
- GPU sandboxes: Provision and manage GPU sandbox environments with flexible scheduling and scaling — suitable for both experimental and production pipelines.
- World Model Runtime (WMR): Underlying runtime is purpose-built for diffusion, video, and world model workloads, meaning inference latency and throughput characteristics differ from standard transformer serving stacks.
- Self-hosting: The platform is open-source and self-hostable, supporting hybrid, on-prem, and sovereign deployment configurations.
- Enterprise controls: SSO, private deployments, and dedicated support are available under custom enterprise agreements.
Developers should consult Hedra's official documentation for endpoint references, authentication, credit consumption rates per model call, and SDK availability.
