What it is¶

Starchild-1 is a research causal world model by Odyssey for teams needing interactive world simulation rather than pre-rendered video.

• Synchronized generation: autoregressively generates synchronized audio and video.
• Streaming input: accepts streaming text, speech, and actions.
• Interactive simulation: demonstrates dialogue, environment navigation, and causal sound effects.

Up to 24 fps on modern hardware.

This is a preview without confirmed public self-serve access. The current Odyssey API page announces Odyssey-2 Max, not Starchild-1.

Development line¶

• 2026-05-19 — Initial public announcement of Starchild-1. Causal model that autoregressively continues synchronized audio and video from streaming input.

What changed¶

2026-05-19 — Starchild-1 is presented as a preview: a causal model that autoregressively continues synchronized audio and video from streaming input.

How to use this¶

1. Read the technical report first and design evaluation as a continuous audiovisual rollout. Check streaming input response and synchronization rather than an isolated clip. — https://starchild.odyssey.ml/starchild-1.pdf
2. Use the Odyssey API page for practical access and confirm that access includes Starchild-1. The current page announces the rollout of Odyssey-2 Max, not Starchild-1. — https://developer.odyssey.ml/

Best practices¶

• Treat "up to 24 fps" as a ceiling on modern hardware. Measure local frame rates directly instead of assuming this speed across every setup. — https://starchild.odyssey.ml/starchild-1.pdf
• Evaluate interactivity through response to streaming input and audiovisual synchronization. This is the claimed distinction from offline fixed-clip generators. — https://odyssey.ml/introducing-starchild-1
• Do not substitute the Odyssey-2 Max API or demo for Starchild-1. Confirm the model identifier and availability with Odyssey first. — https://developer.odyssey.ml/

Superseded by this¶

• Nothing marked obsolete yet.

Still unknown¶

• Public pages list no weights, API ID, pricing, hardware requirements, or working demo link specifically for Starchild-1. Direct integration and model availability cannot be confirmed.
• The official page states 2026-05-17 while the Odyssey index records 2026-05-18. Reasons for the discrepancy and the exact day of the initial announcement are not established.
• Current official pages show no dated update specifically for Starchild-1 after this announcement.
