Nebius today acquired Inferize and folded the team into Token Factory. Terms were not disclosed. The cash print is elastic inference on racks already in the hall — not another megawatt. On the [neoclouds layer](https://www.sotkn.com/stack/neoclouds/) the stuck step is utilisation: who can sell the next token without holding spare GPUs warm to hit the SLA.

## What happened

On 1 October 2026 Nebius said it has acquired Inferize and put the team into Token Factory. The named problem is **cold starts** — load time before the first request — which leave assigned GPUs idle at launch, when demand spikes, when new instances spin up, and when weights update mid-run (including reinforcement learning). That idle time, Nebius says, forces platforms to hold spare capacity to hit service-level targets. Inferize “cuts this idle GPU tax,” so capacity can scale closer to usage ([Nebius newsroom, 1 Oct 2026](https://nebius.com/newsroom/nebius-acquires-inferize-to-strengthen-nebius-token-factorys-production-inference-stack?ref=sotkn.com) — company; same text on the [EQS issuer wire, 13:00 CET](https://www.eqs-news.com/news/corporate/nebius-acquires-inferize-to-strengthen-nebius-token-factorys-production-inference-stack/f17d6c50-11a1-4f87-b8d8-89c91afc33d6?ref=sotkn.com)). Founded in January 2026, Inferize had a working prototype within three months. Terms were not disclosed.

The same calendar day, the public on-demand GPU card stepped up from 1 October for B300, B200, H200 and H100 — the hike this desk covered on 21 September, now live ([Nebius Compute pricing](https://docs.nebius.com/compute/resources/pricing?ref=sotkn.com) — company). Token Factory’s Q3 notes added Batch Inference 2.0, in private beta, which “scales to zero between jobs” ([Nebius, What was new in Q3, 1 Oct 2026](https://nebius.com/release-notes/posts/q3-2026?ref=sotkn.com) — company).

| ---------------------------- | ------------------------------------------- | --------------------------- |
| Event                        | Nebius acquires Inferize into Token Factory | Company, 1 Oct 2026         |
| Terms                        | Not disclosed                               | Same                        |
| Founded / prototype          | January 2026 / within three months          | Same                        |
| Named problem                | Cold starts → “idle GPU tax”                | Same                        |
| Eigen AI                     | \~$643m; signed 1 May, closed 10 Jun 2026   | Company                     |
| On-demand B300               | $7.85 → $9.50 / GPU-hour                    | Price list, from 1 Oct 2026 |
| On-demand B200 / H200 / H100 | $7.15→$8.50 / $4.50→$5.40 / $3.85→$4.50     | Same                        |
| Preemptible B300–H100        | Unchanged vs the pre-1 Oct on-demand column | Same                        |

On-demand percentages are **our arithmetic**: (new − old) / old. B300 is 1.65 / 7.85 = **21.0%**. B200 is 1.35 / 7.15 = **18.9%**. H200 is 0.90 / 4.50 = **20.0%**. H100 is 0.65 / 3.85 = **16.9%**. That 17–21% band is **not** Inferize’s price.

## Why cash cares

On the neoclouds layer the usual earn is billed accelerator time: utilisation times realised price, after hardware carry, power, and hall cost. See [What Is GPU as a Service?](https://www.sotkn.com/explained/gpu-as-a-service-explained/). Inferize does not add a hall. It tries to make more of the existing fleet billable. Who gets paid is the operator that can turn a spike into tokens without spare GPUs sitting warm. Who pays, on the Token Factory meter, is still the customer buying tokens. The second-order move is on Nebius’s cost line: every idle GPU-hour at today’s card is list carry with no token against it.

Our arithmetic, from the 1 October price list, not from a run:

- **One spare B300 is $228 a day of list.** $9.50 × 24 = $228 if the card sits assigned and serves zero tokens. One hundred spare B300s is $22,800 a day — **$8.3m a year** if that headroom never billed (100 × 9.50 × 24 × 365 = $8,322,000). That is list, not realised, and not a company saving. It is the size of the tax Inferize is hired to cut.
- **The hike and the tax sit on the same day.** On-demand is already 17–21% higher. Preemptible rows did not move — B300 preemptible is still $4.30 against $9.50 on-demand.
- **Eigen was a $643m inference buy.** Signed 1 May 2026, closed 10 June. Clarifai, 12 May, had **no disclosed terms**. Do not back-solve Inferize from Eigen.

The 21 September [Wire on the October PAYG hike](https://www.sotkn.com/wire/nebius-raises-gpu-prices-october-2026/) was the rate-card print. Today is software that tries to raise utilisation on the same card.

## What idle GPU tax is

Idle GPU tax is not [take-or-pay](https://www.sotkn.com/explained/take-or-pay-gpu-contracts-explained/). Take-or-pay bills the *customer* for reserved hours after delivery, used or not. Idle GPU tax, as Nebius defined it today, is the *operator* holding extra GPUs so Token Factory can still hit latency when a model is loading, a replica is spinning, or weights swap mid-run.

**Cold start.** Weights have to land in GPU memory before the first token; until they do, assigned cards are on the power bill and off the token meter. **Headroom.** Token Factory advertised a 99.9% SLA at launch on 5 November 2025 — spare capacity sitting ready ([Nebius, 5 Nov 2025](https://nebius.com/newsroom/nebius-launches-nebius-token-factory-to-deliver-production-ai-inference-at-scale?ref=sotkn.com) — company). Guy Bortnikov, Inferize’s co-founder and CEO: “Keeping spare GPUs running is the price of being ready for demand.” **Mid-run updates.** Reinforcement learning that hot-swaps weights is the same tax. The Q3 notes already advertise Batch Inference 2.0 that **scales to zero between jobs** — the batch twin of Inferize’s online claim.

Eigen made tokens cheaper per card. Clarifai was the system layer. Inferize is supposed to make the *fleet* thinner for the same SLA. Software does not connect a dark hall. It can change how many billed tokens a live hall produces. The [Stack](https://www.sotkn.com/stack/neoclouds/what-does-nebius-do/) still has connecting contracted megawatts as the delivery bind.

## The second-order read

| Who                          | Seat                 | What this means                                                        |
| ---------------------------- | -------------------- | ---------------------------------------------------------------------- |
| Nebius / Token Factory       | Operator             | Paid on tokens; idle headroom is unbilled carry at the new card        |
| Inferize team                | Seller of elasticity | Joins Token Factory; cash terms not disclosed                          |
| Token Factory customers      | Who pays             | Still buy tokens — no automatic discount because Nebius cut *its* idle |
| Eigen + Clarifai             | Already inside       | Model/kernel ($643m) and system layer (terms n.d.)                     |
| On-demand GPU buyers         | Same-day card        | 17–21% higher from 1 Oct; preemptible unchanged                        |
| Nvidia / HBM / CoWoS / power | Upstream             | No new tray or watt; more tokens from attached cards                   |

**Who gets paid.** Nebius, if spare-GPU hours become serving hours at a card that just went up. Inferize’s founders get paid on an undisclosed cheque. **Who pays.** Token Factory customers still pay the meter. **Upstream.** GPUs, HBM, CoWoS and power still bind the next hall. **Downstream.** Interactive agents feel cold-start first; batch can already scale to zero.

**By clock.** Rate card: 1 October on-demand step, live today. Software: Inferize acquired today, integration “starting.” Funding: Eigen closed 10 June at \~$643m; Inferize unknown. Delivery: 5 GW contracted versus 0.8–1 GW connected (Q2 guide). Our read: the stuck step is **utilisation of live inference seats**. Ready is not paid. Spare is a cost.

## Two cautions

Terms are **not disclosed**, and no millisecond, GPU-count, or utilisation percentage printed. Do not treat “cuts this idle GPU tax” as a measured saving. Do not import Eigen’s $643m, or Token Factory’s November 2025 “up to 70%” fine-tuning claim, as Inferize results. Integration has started; it has not printed.

Do not mix books. Take-or-pay idle is a customer invoice after delivery. On-demand idle is unbilled operator carry. Preemptible / spot is a third clock — dynamic PVM pricing takes effect **8 October**, announced 22 September, and is interruptible capacity, not Token Factory headroom ([Nebius, 22 Sep 2026](https://nebius.com/blog/posts/introducing-spot-pricing-for-preemptible-vms?ref=sotkn.com) — company).

## What would change the view

- A dated Token Factory utilisation or cold-start print after Inferize is in production.
- Disclosed consideration, or a filing that puts Inferize next to Eigen’s $643m.
- On-demand rows reversing the 1 October step while installed GPUs keep rising.
- Connected power at year-end 2026 well below the 800 MW–1 GW Q2 guide.

## What to watch

- **Integration:** next Token Factory note that names Inferize in production, with a cold-start or idle-GPU figure.
- **Price list:** whether the 1 October on-demand column holds through October, and whether preemptible rows stay flat.
- **8 October:** PVM spot pricing goes live — a different idle pool.
- **Q3 2026 results:** connected megawatts versus the 0.8–1 GW guide, and any Token Factory utilisation language.
- **Batch Inference 2.0:** from private beta to a dated scale-to-zero print.
