Elon’s xAI Startup

xAI is an AI startup founded by Elon Musk on July 12, 2023. Led by Musk himself, xAI brought together top talent from Microsoft, Google, OpenAI, and Tesla right from its inception. The team members have previously worked on projects like AlphaCode, GPT-3.5, and GPT-4.

About four months after its establishment, xAI released its first product in November 2023: an AI chatbot named “Grok.” One of Grok’s standout features is its claim to “answer almost anything.”

Unfortunately, both the Grok chatbot and the Grok series models are confined to the social media platform X (formerly Twitter) and are only available to Premium subscribers, with a subscription fee of $8 per month.

Now, there’s another way to experience Grok: through an API. xAI recently launched its API service, allowing developers to build on the Grok model. 

From now until the end of 2024, each developer (i.e., each registered user) will receive $25 of free API credits per month.

The currently available API model is called grok-beta, not Grok 2, but in testing, its intelligence is comparable to, or even better than, GPT-4 mini. 

This model has a context window of 128K, supports function calls, and system prompts. xAI has announced that a multimodal version of Grok, supporting image input, will be released next week.

Notably, xAI’s REST API is fully compatible with OpenAI and Anthropic, making the migration process very simple.

How to Get Started with Grok API?

To get started, visit the xAI website or directly open the xAI developer link. Click on “Try now” and sign in.

Once you’re on the xAI developer platform, click “Generate API key” on the homepage. It takes about a few seconds to set up completely. Like all other API keys, this key is displayed only once, so it’s recommended to copy it to avoid losing it.

You can view detailed usage of your API keys in the left-side menu. In the “API Models” section, you can see the currently supported models and pricing details.

The input token price is $5 per million tokens, and the output token price is $15 per million tokens. The RPM (Rate Per Minute) is 60, meaning the maximum number of calls per minute is 60.

The price for the grok-beta model is slightly high, considering that OpenAI’s latest GPT-4o model is cheaper. However, with the current $25 free monthly credit, it’s still quite affordable.

Finally, you can check how much of your credit you have used in the “Billing Overview” section. Not needing to bind a credit card is also an advantage of the xAI API.


How to use Grok API with 0 Code?

xAI Base_url/Endpoint：https://api.x.ai/

For those who can code, using Crok’s API is straightforward. It’s similar to using the OpenAI API or Claude API. Just replace the Base URL with xAI and select the grok-beta model.

If you have no coding background but want to experience, you can use an existing front-end UI. 

I recommend NextChat: https://app.nextchat.dev/. 

This popular open-source project on GitHub supports multiple large models and has a great user interface. You can use the xAI API key with zero coding required.

To get started, visit the homepage(https://app.nextchat.dev/) and click on the settings in the bottom left corner. Scroll down and click on “custom endpoint.”

Set it up as shown in the image, and enter the API Key you copied from xAI. After that, create a new mask and start chatting!

That’s it.
