Factory has made GPT-5 the default model across all its droids, including Code Droid, Knowledge Droid, and Reliability Droid.
The company states that GPT-5 is highly agentic and detail-oriented, with built-in behaviors such as scanning context, forming and executing plans, testing results, and checking completeness.
Factory collaborated with OpenAI to integrate GPT-5 into its platform.
