Elon Musk's AI company, xAI, has announced that its application programming interface (API) is now open to the public, offering developers a free API usage credit of $25 per month until the end of the year. This decision was made three weeks after the xAI API entered its public beta phase, aiming to attract more developers to try its tools and platform.

Although the $25 free credit may seem modest, it could be a worthwhile opportunity for developers new to xAI. The API pricing is set at $5 per million input tokens and $15 per million output tokens. In comparison, OpenAI's GPT-4o model and Anthropic's Claude3.5Sonnet model have lower pricing. This means that the $25 credit can only support developers in processing approximately two million input tokens and one million output tokens per month.

xAI noted in its release that its API supports "function calling," allowing large language models to accept user instructions and access application and service functions, even executing these instructions with user authorization. Additionally, the AI's API is compatible with OpenAI and Anthropic's SDKs, facilitating switching between different models for developers.

It is worth mentioning that xAI recently activated the "Colossus" supercluster in Memphis, Tennessee, which houses 100,000 Nvidia H100 GPUs, providing powerful computing power for training new models. This enables xAI to further advance in the field of large language models, with more new models expected to be launched in the future.

Although the current xAI API capabilities are still limited, with users only able to access text functions and lacking image generation capabilities, the company has revealed that it will introduce a new Grok visual model next week. With new features continuously being rolled out, xAI hopes to attract more developers to participate in the construction of its platform.
