# OpenAI Announces Major API Updates with Function Calling and Price Cuts

OpenAI has rolled out significant updates to its API platform, introducing function calling capabilities alongside improvements to model control, context length, and pricing.

The most notable addition is function calling, which allows developers to describe functions to AI models and receive structured data back. This enables applications to reliably connect ChatGPT and GPT-4 to external tools and APIs, making it easier to build AI-powered apps that can take actions like querying databases, sending emails, or retrieving real-time information.

The company also announced more steerable API models, giving developers greater control over AI responses and behavior. Context windows have been extended, allowing models to process longer conversations and documents in a single request.

Perhaps most significant for developers, OpenAI is lowering prices across its API offerings, making AI integration more accessible for startups and smaller projects.
