xAI
xAI is an artificial intelligence company founded by Elon Musk, dedicated to developing advanced AI models and supporting infrastructure. Its core products include the large language model Grok, backed by a large-scale AI computing cluster called Colossus for model training. xAI focuses on advancing AI research and integrates its products with other platforms under Musk's portfolio, including X.
Core Facts
xAI provides an OpenAI-compatible API interface, which was the basis for early @ai-sdk/xai being able to adapt via the Chat Completions endpoint.
@ai-sdk/xai is the adapter-layer provider package in the AI SDK targeting the xAI Grok series of models.
@ai-sdk/zai is the official Provider in the Vercel AI SDK for Zhipu AI models.
Timeline (last 90 days)
A multi-source cross-check of the official OpenAI image generation guide, the Google AI developer forum and the xAI image generation documentation concludes that the only mainstream AI image generation tool that truly supports transparent output is OpenAI.
Grok (xAI) has no documented transparent background output option.
Currently OpenAI, Anthropic, Google Gemini, DeepSeek, Mistral, xAI, and Qwen all offer prompt caching capabilities in different forms.
xAI's speech-to-speech price changed from Starting at $0.05/min to $0.08/min, an increase of 60%.
In the UplinkSwitch sample, xAI's Grok 4.20 Multi-Agent (0309) lowest-price model is $0.75 input and $1.50 output, with absolute prices higher than the entry-level products of the other vendors.
The Grok series launched a joint membership that splits subscription tiers into Plus, Premium, Super, and Ultra, with half price for new users in the first month.
SuperGrok is a standalone subscription tier for individual users, offering higher usage limits and priority access to new models, and previously required separate payment.
Grok is set to an edgy, unfiltered persona aimed at attracting users seeking novelty and directness.
@ai-sdk/xai does not implement xAI's communication protocol from scratch, but is built on top of the compatibility layer @ai-sdk/openai-compatible.
xAI said its enterprise zero-data-retention team has never stored code or trace data, and consumers can run /privacy in the CLI to turn off retention and delete already-synced data; Musk said the previously uploaded data will be thoroughly and completely deleted.
