Documented capability coverage
A documentation-based comparison, not a claim about subjective output quality.
Scoring: 10 = broad, explicit official support; 5 = partial or constrained support; 0 = not documented. API continuity reflects published lifecycle status. This is not a generation-quality test.

Sora 2 documents strong synchronized audiovisual generation and a useful 12-second preset. Gemini Omni Flash offers broader reference controls, 4K, conversational edits and a current API lifecycle. With Sora's API shutdown scheduled for September 24, 2026, avoid starting a new production dependency on it.
