Editorial Verdict

AI-researched, not hands-on tested

Grok is xAI's assistant, available on grok.com, with an API at api.x.ai that offers text, voice, image and video generation, function calling, web search and a Batch API. It fits developers and users already in xAI's ecosystem. A limitation is that the consumer plans page requires sign-in, so subscription pricing could not be confirmed here. For self-hosting, open-weight models such as gpt-oss with Ollama or vLLM are alternatives.
