OpenAI's Sora 2 September-24 API sunset finalizes three-tier video-generation segmentation — Veo / Kling / Runway define the procurement frame H2 2026
OpenAI's Sora 2 web product was deprecated April 26, 2026; the API sunsets September 24, 2026. The exit finalizes the three-tier video-generation market segmentation: Google Veo 3.1 for product-integration, Chinese Kling 3.0 for standalone-platform, Runway Gen-4.5 for marketer-friendly workflow. Each tier now has a single clear procurement-decision path.
The substantive piece is the procurement-decision simplification. Through 2025, AI-video procurement was a confused multi-vendor evaluation across five-plus comparably-capable tools with different pricing, integration patterns, and quality profiles. Sora 2's exit removes the largest US-based standalone-platform player from the field; the remaining three (Veo, Kling, Runway) occupy non-overlapping procurement segments where buyer decisions become deterministic rather than evaluation-heavy. Pricing: Sora at $0.75/sec, Veo at $0.15/sec fast mode, Kling at $0.10/sec, Runway varies — three orders of magnitude price spread justified by integration-depth differences.
The structural read for Veo 3.1's product-integration deployment pattern is that Sora's exit removes the head-to-head competition Google was running against OpenAI on consumer-facing video generation; Veo now operates as the only frontier-class video-generation model with full Big Tech product-stack distribution. Kling holds the standalone-platform Chinese-physics-quality lead; Runway holds the marketer-workflow segment. Each tier has a clear category-leader through H2 2026.
