OpenAI Announces Function Calling, Longer Context, and API Price Reductions
OpenAI introduced function calling capabilities to its API, enabling models to reliably output structured JSON for calling developer-defined functions. The update also includes longer context windows, more steerable models (gpt-3.5-turbo-16k and gpt-4 updates), and reduced pricing on several API tiers. These changes significantly expand the practical utility of OpenAI models for agentic and tool-use applications.
DeepSeek API Major Upgrade: Function Calling, FIM, Chat Prefix Completion, JSON Output, and 8K Token Limit
DeepSeek has released a significant API update adding Function Calling (up to 128 parallel calls, OpenAI-compatible), JSON Output, Chat Prefix Completion, and FIM (Fill-In-the-Middle) Completion to both deepseek-chat and deepseek-coder models. The update also raises the max_tokens ceiling to 8K in the Beta API. Several features are in Beta and will be open-sourced once stable. The Function Calling and JSON Output implementations are explicitly designed to be compatible with the OpenAI API.
