xAI has launched Grok 4.5, its new flagship model for coding, agentic work and knowledge tasks, trained alongside Cursor. The company says it was built across tens of thousands of Nvidia GB300 GPUs, with heavy investment in data filtering and reinforcement learning spanning hundreds of thousands of software engineering tasks.

Its own published benchmarks tell an interesting story. Across DeepSWE 1.0 and 1.1, Terminal Bench 2.1 and SWE Bench Pro, Grok 4.5 trails Anthropic's Claude Fable 5 (max) in every comparison shown, sometimes by wide margins. Grok 4.5 does lead on SWE Marathon.

Grok 4.5 is served at 80 tokens per second, priced at $2 per million input tokens and $6 per million output tokens. EU availability is delayed until mid-July across all SpaceXAI products, xAI said.

The model is also being pitched at Office-style work, with xAI touting capabilities in Excel, PowerPoint and Word.

AI for Leaders: Governance, Risk & Why Strategy Must Come First
Is your organisation adopting AI without a defined strategy or governance? If so, you’re not alone — and the consequences range from data breaches to reputational damage to safeguarding failures. AI is a strategic risk, not a silver bullet, and definitely not a magic data fairy. Without clear ownership, rules, and accountability, AI can proliferate across your organisation in ways that cost more — in time, money, and trust — than not using it at all. Speakers: Craig Clark, Director at Clark & Company Information Governance Services, and Stewart Tinson, Project Director, AI-360. You’ll learn: Why “understand your why” must precede any AI rollout Which risks senior leaders most commonly overlook — from data leakage to safeguarding How to measure AI value through outcomes, not adoption metrics Why accountability for AI governance sits with the C-suite, not IT or compliance Key topics: AI strategy • Risk appetite • Data protection • Bias & fairness • Safeguarding • AI literacy • Governance models • Return on investment • Executive accountability • AI use case tiering For CISOs, CIOs, and senior leaders who need to govern AI responsibly — before it governs them.
