On September 12, 2026, Anthropic CEO Dario Amodei published “We Must Pace the Frontier,” committing Anthropic unilaterally to METR-class evaluators with employee-like access. Sam Altman said OpenAI will do the same; Elon Musk said Dario is right. Pacing is not a halt.

On August 28, 2026, OpenAI said it will stop serving Cursor after SpaceX’s acquisition of Anysphere closes, with a proposed November 12 cutoff. Cursor CEO Michael Truell said OpenAI is about 5% of Cursor traffic; Anthropic’s Tom Brown said Claude compute will fill the gap.

On August 26, 2026, SpaceXAI put Grok 4.6 on Microsoft Foundry in public preview at the same $2 / $0.50 cached / $6 per million tokens as Bedrock and the first-party API, two weeks after the model GA and a week after Amazon and Google cloud ports.

On August 24, 2026, Nvidia said SpaceXAI will deploy Vera CPUs—the 88-core Olympus CPU Nvidia bills as built for agents—to orchestrate Grok’s next agentic workloads, scale Grok infrastructure on Vera Rubin toward gigawatts, and base its first-generation Starmind AI satellite on an optimized Vera Rubin NVL72 rack.

On August 21, 2026, SpaceXAI made Grok 4.6 available on Google Enterprise Agent Platform via Model Garden at $2 / $0.50 cached / $6 per million tokens—the same list as Bedrock two days earlier—with a 500k context window and low through xhigh reasoning effort.

On August 21, 2026, SpaceXAI expanded Grok Bot from the August 11 Heavy/Ultra/Teams Premium beta to SuperGrok Plus, Cursor Pro+, Cursor Ultra, and all Cursor Teams plans. Enterprise remains on a waitlist. Same product line as the beta, new seat map.

On August 19, 2026, SpaceXAI made Grok 4.6 generally available on Amazon Bedrock at the same $2 / $0.50 cached / $6 per million tokens as the first-party API, with a 500k context window and low/medium/high/xhigh reasoning effort, in supported AWS Regions.

On August 19, 2026, SpaceXAI moved Grok Build out of SuperGrok Heavy early beta: describe an app, game, site, or dashboard in Grok and it builds live in chat on web, iOS, and Android, on every plan. Publish to grok.me, remix, custom domains, GitHub export, and in-app SpaceXAI APIs ship the same day.

On August 18, 2026, Guidelight AI Standards published its first public Control assessment of Anthropic, OpenAI, Google, xAI, and Meta. Information current through August 18; no lab scored above 3/5 on any of six practices. Anthropic and OpenAI tied at C+ (2.50); Google D+ (1.50); xAI D− (0.83); Meta F (0.67).

On August 14, 2026, SpaceXAI said Grok 4.6 is live in GitHub Copilot across VS Code, cloud agents, and the Copilot CLI, with some businesses needing to enable the model in Copilot settings; API pricing remains $2/$6 per million tokens.

On August 12, 2026, SpaceXAI released Grok 4.6—a post-training upgrade of Grok 4.5 aimed at long-running agents, coding, and interactive visual work—that ties GPT-5.6 Sol Max at 61 on the Artificial Analysis Intelligence Index, ships at $2/$6 per million tokens, and is live in Cursor, Grok Build, and the SpaceXAI API.

On August 11, 2026, SpaceXAI launched Grok Bot in early beta—always-on agents that share a cloud computer, sign into the same apps a coworker would, and hand work back only when they need approval—available first to SuperGrok Heavy, Cursor Ultra, and Cursor Teams Premium subscribers on desktop and iOS.

On July 31, 2026, SpaceXAI upgraded Imagine Video 1.5 with text-, image-, and voice-reference conditioning (up to seven image references), native 1080p generation, and text-to-video—rolling out first to SuperGrok Heavy and Plus in the US on grok.com/imagine and iOS, with API support for image refs and 1080p on grok-imagine-video-1.5.

On July 29, 2026, SpaceXAI released Grok Voice Think Fast 2.0—its next-generation speech-to-speech voice model—claiming 82.9% on Artificial Analysis’s Speech-to-Speech Quality Index, 0.70s time-to-first-audio, $0.08/min pricing, and a default swap for grok-voice-latest on August 5.

On July 28, 2026, SpaceXAI announced that Grok 4.5—its flagship coding model—is available in GitHub Copilot across cloud agents, Copilot CLI, and VS Code, selectable from the model picker (enterprise enablement required for some orgs), with API pricing at $2/$6 per million input/output tokens.

On July 28, 2026, SpaceXAI introduced Build Mode—an early-beta product for SuperGrok Heavy subscribers that turns a chat prompt into a live website, app, game, or dashboard and publishes it to a shareable grok.me (or custom-domain) link on web, iOS, and Android.

On July 24, 2026, SpaceXAI launched a free Grok add-on for Google Workspace—one install for Sheets, Slides, and Docs from the Workspace Marketplace—so users can ask questions against open files, write formulas and charts, build decks, and draft documents in place, with optional connectors to email and Drive.

On July 16, 2026, SpaceXAI launched Automations in Grok—describe a job once and Grok runs it on a schedule or when matching email arrives—available on grok.com and iOS/Android, with scheduled runs for everyone and email triggers on SuperGrok.

On July 15, 2026, SpaceXAI open-sourced Grok Build—its terminal coding agent and TUI—on GitHub (xai-org/grok-build), publishing the agent loop, tools, terminal UI, and extension system so developers can inspect, extend, or run the harness fully local-first.

On July 8, 2026, SpaceXAI (formerly xAI under the SpaceX/AI stack branding) launched Grok 4.5—its strongest model yet for coding, agentic work, and knowledge tasks—trained alongside Cursor. It ships at $2/$6 per million tokens, ~80 tokens/sec, as default in Grok Build and on all Cursor plans, with API access via the SpaceXAI console; EU availability deferred to mid-July.

On July 6, 2026, SpaceXAI released 21 new flagship voices for Grok Voice—joining the original five—all natively multilingual and available in the realtime Voice Agent API, Text-to-Speech API, and Grok Voice Agent Builder. The company also improved naturalness of the original five voices.
