xAI has launched the Grok API public beta program, which will run until the end of 2024. During this period, developers can access $25 worth of free API credits per month. The API supports OpenAI and Anthropic SDKs, features a 128k token context, function calling support, and custom system prompt support. The initiative aims to attract developers by offering easy integration and competitive features. Additionally, xAI's Grok Beta is noted for its high intelligence, surpassing Llama 3.1 70B, although pricing remains a concern for competitiveness. Image support is expected soon.
