Meta unveiled new AI technologies at its first developer conference in California.

CEO Mark Zuckerberg presented a new Application Programming Interface (API) that allows developers to create AI products based on Meta's Llama model while combining characteristics from other models such as DeepSeek and Qwen, according to Reuters.

The API is currently available in preview for select users, with pricing yet to be announced. APIs are a key revenue source for competitors like OpenAI, the creator of ChatGPT.

Meta has released a standalone AI assistant app focusing on natural voice interaction. Chris Cox, Chief Product Officer, stated that it provides low latency, expressive voice answers, and personalized experiences by tying to users' Facebook and Instagram activity.

Reuters reports that Meta plans to test a paid subscription for its AI assistant in the second quarter.
