xAI Rolls Out Grok 4.7 as Base Model and Introduces Proactive Primary Bot

SpaceXAI has given Grok Bot a proactive Primary Bot that spots work and offers to handle it before you ask, and Grok 4.7 is now the base model across the Fast, Expert, Build and Heavy modes in the Grok apps. We cover how Primary Bot works, what free suggestions really cover, Grok 4.7’s benchmark gains, what is still undocumented, and what it means for businesses.

‘Apple Intelligence saw minimal usage’: OpenAI complains that ChatGPT in Siri was ‘dramatically underperforming’ as hardly anyone was using Apple’s AI

OpenAI told a federal court in Texas on 22 September 2026 that Apple’s integration of ChatGPT into Siri was “dramatically underperforming” by the summer of 2025 and “persistently underperforming” by March 2026, consistent with its internal view that Apple Intelligence saw minimal usage. The admission sits in OpenAI’s summary judgment brief in the antitrust case brought by Elon Musk’s X Corp. and SpaceXAI. This article covers what the 59-page filing says, what its redactions hide, why the opt-in integration struggled, how Gemini, Anthropic and xAI grew regardless, and what comes next for the case and for ChatGPT inside Apple’s new Siri AI.

Discover Grok 4.7, Freshly Added to AIxploria

AIxploria added SpaceXAI’s Grok 4.7 at 01:29 UTC on 24 September 2026, a little over two days after launch. Its blurb calls the model “twice as fast and half the cost,” but SpaceXAI’s own announcement says Grok 4.7 is served “at the same price and speed as Grok 4.6,” and its “half the price” claim referred to rival models such as GPT-5.6 Sol, which OpenAI replaced the next day. We checked 13 claims, worked through the 200K-token pricing threshold, compared Grok 4.7 with GPT-6 Sol and Claude Opus 5.5 on three job sizes, and tested Musk’s pre-launch forecasts.

xAI Develops Remote Control Feature and Grok Desktop Application

xAI has spent four months building a remote control capability for Grok Build in public without naming it. The evidence is a Computer Hub command hidden from the agent’s own help output, roughly 6.1 megabytes of Rust across eight crates in xAI’s own open-source repository, and a trail of changelog entries running from 3 June to 20 September 2026. A Grok desktop application is referenced three times in those release notes and appears on no download page. This article dates every step from primary sources, measures the shipped code, and sets out what the trust boundary looks like if Grok Build already runs on a machine with credentials on it.

Anthropic Updates Claude Projects and xAI Launches Grok Bot Voice

On 17 September 2026 Anthropic rebuilt projects in Claude Code from a folder into a single coordinating conversation: you describe the work, Claude starts a thread for each piece, and every thread is a full cloud session on its own branch with shared project memory and instructions behind it. Hours later, xAI switched on voice mode for Grok Bot, its always-on agent, powered by the same Grok Voice engine it had shipped to developers on fal the day before. This article covers the new architecture, the naming collision with the older Claude Projects workspace, the 200-thread daily ceiling, what Grok Bot voice mode actually is, and what both launches say about agent coordination.

Grok 4.7 Spotted on GCP Quotas Page Ahead of Potential Release

A Google Cloud quota entry for grok-4.7 was reported on 17 September 2026, ten days after a dated identifier leaked through Cursor’s configuration. Neither xAI nor Google has announced anything, and both catalogues still stop at Grok 4.6. We set out what the two artifacts actually prove, why a quota row is the strongest pre-launch signal short of a model card, what the Kalshi and Polymarket books price it at, and how it sits against four public release windows that have already passed.

Grok 4.8 to Feature 2.5T Parameters and New C++ Software Stack

Elon Musk says Grok 4.8 is a 2.5-trillion-parameter model trained with xAI’s new C++ software stack and will start reinforcement learning this week. We check the claim against every parameter count and stack post Musk has made, the delayed Grok 4.7, Grok 4.6’s published benchmarks, and what a 2.5T model means for memory, speed and price.
