Why did OpenAI decide to shut down Sora: Costs, Focus, and Competitive Pressure

OpenAI announced the closure of Sora, an AI video generation tool, just six months after its launch, sparking initial speculation about data usage and strategic intentions. However, closer analysis suggests practical reasons: Sora was costly to operate, struggled to maintain users, and diverted essential resources from other more competitive areas.

After a promising debut, Sora's global user base dropped from one million to under 500,000, despite significant operational costs. Video generation is an extremely resource-intensive AI task, and Sora consumed nearly one million dollars a day in computing capacity.

At the same time, competition in the AI field is intensifying, with rivals like Anthropic gaining ground in more valuable segments. CEO Sam Altman decided to shut down Sora to redirect computing capacity towards areas with stronger adoption and monetization.

The abrupt closure of Sora underscores a broader reality in the AI industry: technical innovation is not enough; products must balance usage, infrastructure costs, and strategic alignment.
