OpenAI switches off the Sora API: why one-vendor AI is a business risk

On 24 September 2026, OpenAI's Sora video API reached its scheduled shutdown, ending developer access to the Sora 2 models, according to several reports. The shutdown had been announced in March, and the consumer Sora app and website had closed earlier, in April. Reports said no direct replacement video model was offered through the API.

For businesses and developers that built products, workflows or client services on Sora, the change meant rebuilding on another provider at short notice. For everyone else, it is a clear case study in a risk that is easy to overlook.

The single-vendor trap

When a new AI capability arrives, the fastest path is usually to build on whichever provider is best at that moment. It works, until:

• the provider shuts down a product, as here
• prices change sharply
• terms change, for example on what content is allowed
• quality changes after an update
• the service is unavailable in your country, or for your payment method

None of these is unusual. AI is a young, fast-moving industry, and providers change direction often. Google, for example, has also announced retirement dates for preview video endpoints, according to AI video release trackers.

How to reduce the risk

1. Avoid hard-wiring one model. Choose tools that let you switch models without rebuilding your workflow.
2. Keep your own assets. Store your finished videos, scripts and prompts yourself, not only inside one provider's system.
3. Keep your brand knowledge portable. Your brand guidelines, characters and templates should live in your own workspace.
4. Watch the announcements. Deprecation notices usually give months of warning; someone on your team should read them.
5. Have a fallback. Know which alternative you would use, and test it before you need it.

How Tari Studio approaches it

Tari Studio offers several image and video models in one place, including our own AK1 and AK2 alongside other leading models under their own names, and lets each team pick the model on every quote. Your brands, characters, templates, scripts and finished results live in your workspace, and every result can be downloaded. When a model changes or retires, you choose another on the next quote; your brand setup, scripts and library stay where they are. How the Studio works.

The bigger picture

Questions to ask any AI provider

Before you build on an AI tool, ask:

• How much notice do you give before retiring a model or feature?
• Can I export my content and data at any time?
• What happens to my data, and how long is it kept?
• How often do prices change, and how will I be told?
• Is the service available in my country, and can I pay in a way that works here?

The answers tell you how much risk you are taking on.
