xAI's Grok 4.7 is now accessible through Amazon Bedrock via cross-Region inference profiles, offering a 500K token context window and four configurable reasoning effort levels. The model supports the Responses, Chat Completions, and Converse APIs, with Bedrock features including prompt caching, Guardrails, and structured outputs.

xAI's Grok 4.6 is now available on Amazon Bedrock via both bedrock-mantle and bedrock-runtime endpoints, adding Converse API support, cross-Region inference profiles, and Bedrock Guardrails. The model offers a 500K token context window and four reasoning effort levels, with input pricing starting at $2.00 per million tokens on the global inference profile.

xAI has released Grok 4.7, the successor to Grok 4.6, listed on OpenRouter with a 500K token context window and pricing of $1.60 per 1M input tokens and $4.80 per 1M output tokens. The company claims improvements in long-running software engineering tasks, self-verification, and professional document drafting.

xAI's Grok Bot lets users connect agents to services like X, Google Calendar, and Freshdesk through a simple browser login instead of API keys or MCP configuration. A five-day hands-on report compares it to OpenClaw 2.0, released the same week, framing the two as a managed agent computer versus a user-owned agent platform.

xAI's new Imagine Image 2.0 lands in second place globally on both the Image Edit and Text-to-Image Arena leaderboards, trailing OpenAI's GPT-Image-2. The model ships with editing tools including Magic Wand, Multi-Ref Editing, and Smart Resize.

xAI has made Grok 4.3 generally available on Amazon Bedrock, marking xAI's debut as a Bedrock model provider. The multimodal model offers a 1 million token context window, configurable reasoning effort (none/low/medium/high), and runs on Bedrock's Mantle inference engine using OpenAI-compatible APIs.

Yann LeCun, former Meta chief AI scientist and founder of AMI Labs, called Elon Musk's xAI a "failure" that won't be able to compete with OpenAI and Anthropic. LeCun warned that AI labs are at risk of a "big bubble explosion" because current pricing doesn't cover operational costs, with services funded primarily by investors.

xAI has released Grok Build 0.1, a coding-specialized model with a 256K context window and unlimited text output. The model is designed for agentic software engineering workflows and powers xAI's Grok Build CLI tool.

xAI has released Grok Build, a coding agent and CLI tool positioned to compete with Anthropic's Claude Code and other AI coding assistants. The early beta is available exclusively to SuperGrok Heavy subscribers at $300 per month.

xAI is deploying Grok to Apple CarPlay following iOS 26.4's April 2026 update that introduced a Voice Control template for third-party AI chatbots. The move puts Grok alongside ChatGPT, Perplexity, Claude, and Gemini on 800 million iPhones, marking xAI's first deployment outside the Musk ecosystem.

xAI has released Grok 4.3, a reasoning model with a 1 million token context window and no output token limit. The model accepts text and image inputs, has always-on reasoning that cannot be disabled, and uses tiered pricing starting at $1.25 per million input tokens and $2.50 per million output tokens.

xAI has released Grok 4.20 Multi-Agent, a variant designed for collaborative agent-based workflows with a 2-million-token context window. The model scales from 4 agents at low/medium reasoning effort to 16 agents at high/xhigh effort levels, priced at $2 per million input tokens and $6 per million output tokens.

xAI released Grok 4.20 on March 31, 2026, its flagship model featuring a 2 million token context window, $2 per million input tokens and $6 per million output tokens pricing, and toggleable reasoning capabilities. The model includes web search functionality at $5 per 1,000 queries and claims industry-leading speed with low hallucination rates.

xAI's Grok 4.20 scores 48 on Artificial Analysis' Intelligence Index—6 points ahead of Grok 4 but trailing Gemini 3.1 Pro Preview and GPT-5.4 at 57. The model distinguishes itself with a 78% non-hallucination rate on the AA Omniscience test, the highest recorded across any model tested.
