xAI is releasing Grok 4.6 (2 trillion parameters) and 4.7 (4-6 trillion parameters) within weeks of Grok 4.5, backed by a 555,000-GPU Colossus cluster expanding toward 1 million GPUs. The pricing—$2 per million input tokens, 60% below Anthropic and OpenAI—and release cadence create renewal pressure on enterprise API customers locked into costlier competitors.
This Wire brief sits within Fusion42's coverage of AI Frontier Models.
◆ ◆ The Wire takeaway
If you've locked your team into an OpenAI or Anthropic API contract, your renewal conversation just got harder: xAI is shipping models fast enough to keep your renewal cycle short and pricing them 60% lower on the tier that actually matters for agents. Your contract is only safe if switching costs exceed what you'll save.
