Brightray targets a one-year build for a 10MW Indiana AI data center on a nonbinding letter of intent

Brightray has signed a nonbinding letter of intent for a 10MW Indiana AI data center that it aims to deliver within a year using factory-built modules. The twelve months run from a definitive contract that has not been signed, so the date cannot yet go into a plan.

Three US providers host Moonshot's Kimi K3 at a tenth the cost of going to the source

Kimi K3's 1.4 terabytes of weights take eight Nvidia GB300s just to sit in memory. Export controls keep those chips away from Moonshot. Modal, Fireworks and Baseten price the hosted result at $3 in and $15 out.

OpenAI's first Jalapeno numbers buy it leverage, not a procurement input

The 1.7x to 3.6x latency range is set by the baseline systems, not the chip, and the report's own publication date is unsettled. Read it as direction, not evidence.

Microsoft's $19.4bn Nebius contract works out to under $194,000 per GB300

The deal is the largest slice of more than $33bn Microsoft has committed to specialist GPU clouds. It leaves the fleet, the debt behind it and the 18-month depreciation clock on someone else's balance sheet.

G42 reportedly explores selling control to Americans to keep chips flowing past April 2027

Bloomberg says executives have discussed an American majority shareholder. G42 already pulled Huawei gear out of its racks and wired US-specified monitoring into its own data centres, and each concession came with an expiry date.

DeepSeek's MIT-licensed V4-Pro hands API buyers a credible walk-away option

The release attaches speculative decoding to weights it publishes under MIT, which lowers what a self-hosting threat costs to stand up, even though the performance claim behind it is still the vendor's own.

Nvidia's power pitch: 40,000 Rubin GPUs in 100MW, or 2.5kW a GPU at the meter

The zettaFLOPS figure is an estimate. The measured one, sitting in a GB300 example, is a 25 percent density gain, and it is paid for out of the safety margin.

A 180kW rack, an 18-month transformer, and a shortfall nobody has shown the math for

Nvidia's newest racks draw more than utilities planned for, and grid equipment is the queue that matters. But the headline gigawatt figures do not add up to the shortfall being advertised.
