Migration support Learn how to migrate from other OpenAI models to the GPT‑5 series. Model best practices Learn how to optimize GPT‑5.6 performance from our startup community. The all-in-one platform for agents Build agents that use your context and tools to get work done across your systems. Create agent workflows with the Agents SDK and Responses API, and add voice with the Realtime API. Give agents relevant context through built-in tools like web search, file search, and remote MCP servers. Connect agents securely to business systems so they can take action across workflows. Bring AI experiences to life Build natural-sounding voice agents with Realtime API ⁠ (opens in a new window) for rich customer experiences and support. Zillow makes home and financing searches easier with voice using the Realtime API. Use cases driven by our platform Accelerate development cycles with models that write, review, debug, refactor, and migrate code. Customer support Deliver faster customer support with models that resolve issues autonomously and handle customer queries. Personalized recommendations Surface recommendations tailored to your customers to drive engagement, retention, and revenue. Research & data analysis Turn complex data into clear insights and synthesized findings. Content generation Produce high-quality content across text and image to match your brand's look and feel.
