Summary
OpenAI announced on June 3, 2026, that it is deprecating Agent Builder, its no-code tool for creating AI agents. The company is notifying affected developers and recommending migration to either the Agents SDK for programmatic development or ChatGPT Workspace Agents as replacements. This move reflects OpenAI's broader strategy of consolidating its agent development offerings around more capable and flexible solutions.
Developers using Agent Builder have time to plan their migration. OpenAI follows a standard deprecation notice policy of at least 3 months for specialized product variants, allowing time to evaluate alternatives and complete transitions. ChatKit remains available as an additional platform option for developers seeking no-code or low-code agent development capabilities.
The deprecation is part of OpenAI's ongoing product evolution as it regularly retires older tools and models to make room for safer, more capable alternatives. The company communicates all deprecations via email to affected customers and maintains detailed documentation of migration paths.
