Status: Active
Function calling is the foundation of agentic AI, and OpenAI has been steadily improving GPT-4o's reliability. Simple schemas (fewer than 5 parameters, no nested objects) are approaching production-grade reliability. This prediction tests whether the final reliability gap for simple use cases will close by Q3 2026.
