The application takes a free-text affiliation field and no institution check - the program's creator says an academic affiliation is not required, and a vocational-school applicant and a first-time applicant both describe filling the field by hand. But the quota lands on a Google Cloud project, and getting a project to the point where it can create a TPU VM requires GCP billing verification, which requires a card. The best evidence is a 2026-04 post from an accepted applicant: 'The TPU Research Cloud (TRC) team was awesome enough to grant me a v5e/v6e cluster quota, but I'm totally stuck on the infrastructure side. Since I'm a student in Bangladesh with a $0 budget and no international credit card, I can't pass the billing verification to actually spin up the TPU-VMs or the GCS buckets I need.' So the door is a card, not a degree, and the card obeys Google's billing rules: an authorisation request with 'a value between $0.00 and $1.00 USD' that 'is a hold, not an actual charge', prepaid cards not accepted, virtual cards possibly refused.","country":null},"reliability_note":"no reliability event recorded","confidence":"documented","evidence":[{"url":"https://sites.research.google/trc/about/","date":"2026-10-22","proved":"'TRC enables researchers to access a cluster of more than 1,000 Cloud TPU devices.

What does gate it is a GCP billing account, because the TPU attaches to a project. A 2026-04 post from an applicant who was actually granted v5e/v6e quota is the proof - they could not provision anything without a card. Three facts now stand on quoted evidence. The shape, from an activation email quoted verbatim by an accepted applicant: 5 on-demand v3-8 hosts, 5 on-demand v2-8 hosts and 100 preemptible v2-8 hosts, free for 60 days. The value, by arithmetic over the vendor's own per-chip-hour list price: USD 126,720 of on-demand v3 capacity, preemptible quota excluded. The time box, which is the weakest-evidenced field: the vendor says only 'temporary'; applicant reports give 30 days (three sources), 60 days (two sources), and one month extended to three on request (one source). Treat 30 to 60 days as the working range. Still open: the quota a new grant is actually set to in 2026. Every quoted shape predates the v3 decommission, and the v6e report gives a slice type without a count. No page read settles that; only the activation email does. The program is live as of this read: its publications page carries September 2026 entries. The one recorded is the better-evidenced.","extras":{"facets":{"class":"research-credit","free_tier_kind":"recurring-credit","shape":{"vcpu":null,"ram_gib":null,"gpu_class":"Cloud TPU","gpu_count":null,"tpu_generation":"v4/v5e/v6e as of 2025-10; v2 and v3 were the grant generations through 2023 and v3 was decommissioned","tpu_slice_shape":"per-applicant quota, not a fixed shape.
