Anthropic API: Claude API for developers

Conversational AI assistant from xAI with multimodal capabilities and local model support
Overview
Grok is a conversational AI assistant developed by xAI, Elon Musk's AI research company. The platform combines text generation, image understanding, video creation capabilities, and function calling for tool use. Grok competes with ChatGPT, Claude, and Perplexity as a general-purpose conversational AI assistant. xAI offers Grok through multiple channels: a web application at grok.com (402-blocked, unaccessible), integration within X platform, and programmatic access via the xAI Python SDK (xai-sdk). The SDK supports synchronous and asynchronous clients, requiring Python 3.10+. Authentication occurs through API keys stored in environment variables or passed explicitly. The platform offers reasoning models with configurable effort levels, structured outputs via Pydantic models, and agentic tool calling for autonomous web searches and code execution. Grok-1 is available as an open-weight model with 314 billion parameters using a Mixture-of-Experts architecture. xAI maintains active development with recent releases including Grok-4.6 and specialised models like grok-imagine-video. The ecosystem includes cookbooks demonstrating real-world usage patterns. Specific pricing is not published publicly; access appears to require contact with xAI directly. The platform differentiates through Elon Musk's backing, integration with X for social media context, and open-weight model availability.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Grok.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Softwr does not host reviews and shows no star rating for Grok, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it. Tell us if any of it is wrong.
