Elon Musk's AI lab building the Grok family of frontier large language models, now merged into SpaceX.
Elon Musk's xAI filed a federal lawsuit against a user accused of misusing Grok's image generator to create child sexual abuse material, one of the first times an AI company has sued its own users rather than only banning accounts.
Jul 16, 2026GPT-5.6, Grok 4.5, Claude Fable 5's extended access and a Gemini 3.5 Pro launch expected July 17 have landed within roughly two weeks of each other -- a release pace that's becoming a durable procurement challenge in its own right.
Jul 14, 2026GPT-5.6, Grok 4.5 and a rebuilt Gemini 3.5 Pro have all landed or are landing within weeks of each other -- a release pileup that rewards buyers who wait for real benchmarks over those chasing the newest name.
Jul 13, 2026SpaceXAI's Grok 4.5 launched at $2/$6 per million tokens -- roughly half what comparable frontier models charge -- with Elon Musk calling it "comparable to Opus 4.7, but much faster."
Jul 8, 2026SpaceXAI launched Grok 4.5 priced at $2 per million input tokens and $6 per million output tokens, undercutting Anthropic and OpenAI's premium tiers by more than half while claiming comparable coding performance.
Jul 8, 2026TechCrunch reported July 1 that SpaceX has been developing an AI-focused hardware device that 'sure sounds phone-ish,' citing internal sourcing on a project exploring a Starlink-connected, xAI-powered consumer device. Elon Musk publicly denied the specific report within hours, per The Verge, even as SpaceX's fresh public-market currency (following its roughly $2.1 trillion day-one IPO valuation) and its $60 billion all-stock acquisition of Cursor make a hardware-plus-AI push entirely plausible.
Jul 1, 2026As Elon Musk pitches data centers in orbit to power the next wave of AI compute, skepticism is mounting -- and SoftBank's Masayoshi Son, himself one of AI's biggest spenders, is among the doubters. Critics question the physics, economics and cooling realities of running AI clusters in space, casting the idea as visionary marketing more than near-term infrastructure.
Jun 27, 2026Amazon made xAI's Grok 4.3 generally available on Bedrock, making xAI the third major independent lab on the platform alongside Anthropic and OpenAI. Priced at $1.25/$2.50 per million input/output tokens with a 1-million-token context window, Grok 4.3 lands as the cheapest US-lab frontier reasoning model on Bedrock.
Jun 21, 2026One of the field's most influential researchers publicly argued that xAI has failed to become the frontier challenger Elon Musk promised three years ago, as OpenAI, Anthropic, and Google pull further ahead on both models and revenue. The critique lands as Musk's attention -- and SpaceX's newly public balance sheet -- sits elsewhere.
Jun 18, 2026xAI's Grok 5, the rumored ~6-trillion-parameter flagship, has missed both its Q1 and Q2 2026 windows and remains in training, with full API access now looking like a Q3 story. Prediction markets price a public release before June 30 at roughly 7%, even as xAI ships smaller updates like Grok Voice and Grok Imagine Video.
Jun 16, 2026Gemini 3.5 Pro, Claude Fable 5/Mythos 5, rumored Sonnet 4.8, and Grok 5 -- four frontier launches in a single month signals the arms race has entered a new phase where competitive moats are measured in weeks, not quarters.
