Fly.io

Nobody new: Fly.io no longer rents GPUs. Teams that ran inference on Fly GPUs need another provider.

medium portability Movable with effort. Expect to redo images, storage wiring and networking.

Fly.io retired its GPU Machines on 31 Jul 2026

Fly's pricing page carries no GPU line on 9 Oct 2026, fly.io/docs/gpus/ redirects to the February 2025 post 'We Were Wrong About GPUs', and a Fly email quoted on Fly's community forum (11 Feb 2026) says GPUs are fully deprecated as of 31 Jul 2026.

Checked 9 Oct 2026 on fly.io. The profile below is kept so links to it still answer, and describes what was offered.

What you are buying

Business model
Purpose-built GPU cloud. Owns or leases its own datacentre capacity and sells it directly.
How you reach it
You push a container image and it runs. No cluster to operate.
Accelerators
None since 31 Jul 2026. Fly.io rented A100 and L40S GPU Machines; its pricing page lists no GPUs on 9 Oct 2026.
Regions
No GPU regions since the retirement.
Pricing model
No GPU pricing: GPUs are no longer on Fly's pricing page (read 9 Oct 2026). When offered, GPU Machines were billed per second and scaled to zero.
Getting started
Not available: the GPU product has been retired.
Capacity
None. GPU Machines were deprecated as of 31 Jul 2026, according to a Fly email quoted on Fly's own community forum on 11 Feb 2026.
Ownership
Private.

Verified 2026-09-09. Fields reading “not published” are exactly that — we do not estimate a figure a vendor withholds.

The counterparty

The GPU product was an extension of an established application platform, and Fly has since withdrawn it.

A multi-year GPU commitment is a credit decision wearing a cloud contract. This is the section no benchmark covers and the one that decides what happens to your workload in 2028.

The catch

The GPU product is gone. fly.io/docs/gpus/ now redirects to Fly's February 2025 post 'We Were Wrong About GPUs'.

The economics

Not applicable since the retirement.

No rate is quoted on this page on purpose. Published list prices at this layer move weekly and essentially nobody signing a real contract pays them. Dated, sourced figures live in the GPU cost calculator, where the cheapest and dearest published on-demand price for the identical H100 sit 5.6× apart.

The layers underneath this one

Whatever you rent here is a chip in a building that needs power. In 2026 megawatts, not silicon, are the binding constraint on the whole industry — a frontier rack draws 120–200 kW against a 2026 average near 27 kW, and the US interconnection queue exceeds 2,600 GW.
