Don't ask if AI is a bubble, watch the canaries.

The term comes from coal mines. Miners carried canaries underground because carbon monoxide is invisible and odorless. The birds would stop singing long before the gas turned deadly, giving everyone time to get out.

Software engineers borrowed the idea for canary releases: ship new code to a small group first, catch bugs early, and limit the blast radius before it spreads.

AI canaries work the same way: spot the risks early, contain the damage before it's too late. Metrics, companies, and trends that should crack first if the AI story starts to break.

If the canaries keep singing, the thesis holds. Listen to them for free at substack in bio.

$NBIS: Many things to be excited about after the earnings release, but I think this will fly under the radar.

“The customer was looking for a large-scale contiguous GB300 cluster. Also, flexibility for future expansion, as well as strong technical support and a long-term strategic partnership. When we closed with them in May, they cited our responsiveness, our transparency, the white glove support they received, and our ability to provide their current U.S. deployment needs as well as future sovereign expansion as key differentiators. We are now in discussions with them for more capacity, and they are exploring our inference solution, Token Factory. All of these wins were earned wins, not inbound walk-ins. We had multiple engagement cycles before closing. The customers validated our technology through hands-on POCs. One of them told us it was quite literally the best POC they have ever had”

Nebius took one page from the $PLTR’s book: be first in class, all the rest will follow.

$NBIS Anyone can sell you GPUs. Few will sit next to you and help you use them.

Higgsfield AI CEO Alex Mashrabov: "From day one, Nebius felt like a co-engineer, not just a cloud provider"

Revolut: the strong engineering synergy is "a core driver" of the partnership

Sword Health got custom speculative decoding built by @nebiustf team specifically for their workload. This allowed their model to grow 8x larger, without becoming unbearably slow in production

SGLang and Nebius engineers have put their heads together to optimize LLMs. "Nebius knew the hardware and scaling. SGLang knew the models"

Recraft worked directly with Nebius's in-house engineering team through their entire Hopper-to-Blackwell migration

Compute gets you started. Engineering is what gets you unstuck.

$CRWV's earnings on August 11 will be a key signal for the whole neocloud story.

In Q1, their adjusted operating margin was only 1%. This is caused by a misalignment between the costs of the shell, lease, power, and depreciation, which start immediately, and fit-out, which usually delays revenue by up to 3 months.

However, now that 1GW+ is already online, management thinks they've reached escape velocity, with margins expanding sequentially.

In the last 4 prints, the market has consistently punished CoreWeave. If 1GW turns out to be the real inflection point, it could be a huge signal for $NBIS and $IREN in the coming months.

$NBIS: after open source summer, next comes orchestrating many open models

Imagine: would you pay Gordon Ramsay $1,000/hour to cook your lunch? Maybe for one of his technically demanding dishes. But for every weekday lunch? Probably not. A local chef who knows the cuisine you love does the job just fine, for $50/hour

This is roughly what's happening with LLMs right now: frontier models reserved for genuinely hard problems, open models starting to be preferred for everything else

But it doesn't stop there. Even your $50/hour chef doesn't need to peel their own potatoes or slice their own onions. The tasks can be assigned to a trainee for $10/hour. Every task in the kitchen gets matched to the cheapest hands that can do it well. You, the diner, don't ask who peeled the potatoes. You care whether the dish was worth what you paid

Nebius's bet is that enterprises will move the same way, from paying for tok/s to paying for $/result. Frontier, mid-tier, and small models all working together, each task routed to whichever one gets it done at the lowest cost without sacrificing quality

Whoever builds the best routing, the "head chef", deciding who does what, has a real edge

And don't get me started on the advantages of designing your own equipment and owning the whole kitchen...

$NBIS: Birmingham Mayor Randall Woodfin revealed in a recent interview that the site had been used for data center operations before and that previous court rulings involving other development moratoriums made it clear the city could not include projects that had already begun the permitting process.

He said the city had no way to stop the Nebius project.

“There was no backroom deal. It was simply legally allowable land use prior to the moratorium.”

$NBIS: lawsuit in Birmingham, Alabama to resume on August 12.

The City, Nebius and Hoar Construction were sued over allegations that the city illegally permitted the project. The preliminary injunction hearing to halt construction was held on July 14–16 and will resume next week.

The plaintiffs argue that the site sits in a mixed-use zoning area, which requires the use case of the project to be part of an enumerated list. None of "data center," "hyperscale data center," or "AI factory" is part of it, making the permits illegal. A gap the city itself only closed when it passed new data-center regulations in June, following a moratorium triggered directly by the Nebius project.

The city and Nebius counter that the ordinance empowers Katrina Thomas, director of Birmingham's Planning, Engineering and Permitting Department, to "categorize new land uses not enumerated in this title according to the most comparable land use classification."

The plaintiffs' attorney, Mark Parnell, argues Thomas should have known a hyperscale facility didn't belong in that category, since her own office's investigation is what prompted the city to seek a moratorium in the first place.

Thomas testified that because data centers had previously been permitted in Oxmoor Valley under that same zoning, she had little choice: "The use of their property was permitted. To deny a permit, even though they meet the requirements of the ordinance, would be arbitrary on our part."

Judge Crayton has set aside all of August 12 to finish the hearing.

A separate lawsuit, filed by the Greater Birmingham Humane Society, is also seeking judicial review of the project's approvals and permits, driven by concern over noise, heat, and light from the facility affecting animals at its planned adjacent campus.

$NBIS is considering an auction model for preemptible machines, where the bid determines the level of compute guarantee.

Current options:
- Pay-as-you-go: highest price, highest priority

- Reserved: lower price in exchange for a long-term commitment

- Preemptible: discounted spare capacity that can be reclaimed by Nebius for higher-priority customers, suitable for workloads that can tolerate interruptions

Nebius says its platform is currently strong on reservations, but it wants to continue investing in pay-as-you-go and evolve the platform to provide “more and more spot-like capabilities.”

$NBIS: Aerial image of the Schuylkill County, Pennsylvania site.

On August 8, John Sutter (Nebius Vice President of Public Affairs) and the team proactively organised an open house to hear directly from Schuylkill County residents. As expected, the biggest concerns were energy and water usage.

Nebius assured residents that ratepayers would not be burdened with higher electricity costs and water usage would be in line with other businesses in the park. The company reiterated its intention to protect the environment and be a net positive to the community.

Some residents said that if these concerns are properly addressed, they could absolutely get behind the project moving forward.

The plan is to start with 2 buildings and eventually expand to 4 as part of a 3-year project.

$NBIS: The board is not going to vote today 🟡

Some takeaways from tonight's planning board meeting (mostly debunking false claims about modern datacenters):

- Grid: No impact on the city grid, the project will not cause any increase in electricity prices

- Gas: South Jersey Gas retains the right to interrupt service to prioritize the community during periods of high demand. Nebius will manage that risk via its on-site LNG tank

- Water: Bloom cells use only a small, one-time amount of water to fill. Same for the facility's closed-loop cooling system. A reservoir will supply the ~8M gallons/year needed (up to 20M during exceptional heatwaves). This will not impact the city water system, and keeps the datacenter below the 5th-largest water user

- Emissions: Bloom fuel cells do not require permitting in New Jersey. NOx emissions are 96% lower than conventional generation, and CO2 emissions are 15-30% better. The expected lifecycle of the power modules is 5 years. Servers are quiet, and heat generation will not affect nearby properties

- Noise: A report from July 2026 shows that noise measurements comply with ISO standards and New Jersey regulations

- Overall: All regulations, permits, and procedures required for the project and components have been followed correctly

$NBIS: August 5th could be a big day for the Vineland data center. Here is the full story, and why I am cautiously optimistic.

The Vineland Planning Board meets August 5 to vote on DataOne's amended site plan.

This hearing has already slipped multiple times since its original date of March 26, each time tied to DataOne revising its plans, including the shift from gas engines to Bloom Energy fuel cells. Residents are actively organizing opposition ahead of the hearing over noise, water use, and electricity demand.

Worth understanding how this actually works: it's a quasi-judicial hearing, not a town hall. DataOne presents its case through expert witnesses (engineers, traffic consultants, planners) testifying under oath. The public gets a comment period, but it's more structured and limited than an open town-hall format.

Why am I leaning optimistic on approval?

- It's an amendment, not a fresh entitlement. Phase 1 is already built and operating, and the original site plan was approved back in 2024.

- Power: DataOne's original natural-gas plan already called for producing 85% of the site's energy on-site, limiting reliance on grid power. On top of that, the shift to Bloom Energy fuel cells is a real emissions improvement over the original gas-engine design (for comparison, Oracle reported a ~92% NOx cut from a similar fuel-cell switch at its Doña Ana site in NM).

- Water: DataOne says the facility uses a closed-loop system needing only an initial fill plus occasional top-offs, with overall consumption below some existing industrial users already in Vineland.

- Noise: On March 10th, Cumberland County's Health Dept issued a formal Notice of Violation for noise exceeding 50 dB between 10pm–7am. DataOne says it's since fixed this, citing county monitoring showing full compliance as of April.

Finally, Nebius just published its 2025 Sustainability Report on July 30th, showing concrete engagement with the community and a drive to minimize disruption in the areas where it operates.

I think it was said quite a few times: having something working in a PoC is not the same as scaling in production. And many times the unit of economics doesn't work. A lower cost per token will unlock many more use cases and attract on Token Factory many more enterprise customers, which are the most important segment for Nebius (big budget, but no dedicated AI/ML team, so happy to pay Nebius for serving and managing infra)
