Oracle said it has deployed OpenAI GPT-5 across its applications and database portfolio in what amounts to more choices for Oracle customers and additional distribution for OpenAI.

The database giant said that it is using GPT-5 across its Oracle Fusion Cloud Applications, Oracle NetSuite and Oracle industry offerings such as Oracle Health. GPT-5 will also combine with Oracle Database 23ai and Oracle AI Vector.

OpenAI has been using Oracle Cloud Infrastructure for workloads as well as Google Cloud as it diversifies its Microsoft Azure compute base.

According to Oracle, GPT-5 will be available in three sizes to its SaaS and application customers. Oracle customers could also use ChatGPT Enterprise for GPT-5 access.

Last week, Oracle said Google Cloud's Gemini models and Vertex AI will be available to customers.

Holger Mueller, an analyst at Constellation Research, said Oracle's move to add OpenAI GPT-5 is a natural progression given OpenAI is using Oracle Cloud Infrastructure more. If the training is in OCI, it may be possible to get OpenAI on OCI faster.

Mueller said:

"Oracle is on a roll and has three ways with OpenAI to create value. First it trains OpenAI models on OCI. Now it allowed enterprises to use Chat-GPT 5 to use data from the Oracle Database via Vector search and Model Context Protocol. Those same customers can use that custom ChatGPT-5 result with their Oracle Fusion applications."

Separately, Oracle said it is adding OpenAI's two open weight models--gpt-oss-120b and gpt-oss-20b--to OCI Data Science's No Code Interface.
