GROK 5 IS NOT COMING THIS QUARTER: XIAI IS BURNING 1.5 GIGAWATTS TO TRAIN IT AND STILL HAS NO RELEASE DATE Elon Musk’s xAI is burning more electricity than a small city to train Grok 5 and still has no idea when it will be ready. The company expanded its Colossus 2 supercomputing cluster to 1.5 gigawatts of operational capacity specifically for this training run, a figure that dwarfs every announced AI training facility currently operating. Despite that scale, prediction market platform Polymarket closed June 30 contracts for a third-quarter Grok 5 release at approximately 3 percent probability, reflecting near-universal market consensus that Q3 is not happening. xAI has not provided a release date or a timeline. The last model in public availability remains Grok 4.3, accessible through Amazon Bedrock at $1.25 per million input tokens and $2.50 per million output tokens. That model has been competitive on coding benchmarks but trails Claude Fable 5 and the GPT-5.6 Sol preview on frontier reasoning tasks. The Colossus 2 investment does carry a message. xAI would not build at 1.5 gigawatts for an incremental release. When Grok 5 arrives, most likely in Q4 2026 at the earliest, it is expected to compete directly at the frontier performance level against Claude Fable 5 and GPT-5.6 Sol. The question is whether Anthropic and OpenAI will have moved the bar again by the time it gets there. For now, Grok 4.3 on Bedrock remains xAI’s best public offering while its competition releases new flagships every few weeks.
