The short version

  • Only PyTorch has a free tier, so it costs nothing to try first.
  • Each has a real cost: PyTorch dynamic computation graph can be less efficient for production inference than static graphs; Quartzy the vendor earns margin on supplies bought through its own Shop, so the recommended purchasing path is not necessarily the cheapest one for a university that already holds negotiated supplier contracts.
  • They diverge on capability: PyTorch covers Dynamic computation graphs, Quartzy covers Inventory tracking.
  • Prices and features above were last checked on 31 August 2026.

Quartzy

  • An academic lab of three postdocs replacing a shared freezer spreadsheet that nobody updates after a reagent runs outnot PyTorch
  • A small biotech that wants requests approved by a lab manager before any money is committednot PyTorch
  • A principal investigator tracking consumable spend against separate grant codes for reportingnot PyTorch
  • A growing company standardising ordering across two lab sites so duplicate reagent purchases stopnot PyTorch

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

PyTorch

  • Dynamic computation graph can be less efficient for production inference than static graphs
  • Requires more manual code for distributed training compared to some alternatives
  • Documentation focused heavily on research use cases rather than production deployment

Quartzy

  • The vendor earns margin on supplies bought through its own Shop, so the recommended purchasing path is not necessarily the cheapest one for a university that already holds negotiated supplier contracts.
  • Seat limits are tight, at three users on Academia and five on Industry, and exceeding them pushes you into a quoted Enterprise contract rather than a predictable per seat increment.
  • It is not a LIMS: there is no sample workflow, instrument integration, electronic lab notebook or 21 CFR Part 11 audit trail, so a lab moving toward regulated work will need a second system.
  • Prices are billed annually, so the USD 250 Industry plan is a USD 3,000 upfront commitment for a five-person team, which is significant for an early-stage company.
  • Supplier catalogue coverage and pricing accuracy vary by region, and labs outside the United States frequently find their usual distributors missing or their contract pricing not reflected.

Answered from the vendors’ own pages

PyTorch: Is PyTorch free and open source?

Yes. PyTorch is an open source machine learning framework that is completely free to use. It was originally created and open-sourced by Facebook (now Meta) in 2016.

Source
Quartzy: How much does Quartzy cost?

USD 50 per month billed annually for up to three users on Academia, USD 250 per month for up to five users on Industry, and quoted pricing for unlimited users on Enterprise.

PyTorch: What platforms does PyTorch support?

PyTorch supports Linux, Windows, and macOS. It provides strong GPU acceleration through CUDA and other backends for high-performance computing.

Source
Quartzy: Do I have to buy supplies through Quartzy?

No, you can record orders placed elsewhere. But the Shop is how Quartzy earns beyond the subscription, and supplier credits are tied to it.

PyTorch: Can I use PyTorch for production deployments?

Yes. PyTorch provides graph-based execution, distributed training, mobile deployment, and quantization features to support production deployments.

Source
Quartzy: Is Quartzy a LIMS?

No. It handles inventory and purchasing. It does not do sample workflow, instrument data or regulated electronic records.

Quartzy: What happens when we exceed the user limit?

You move to Enterprise, which is quoted rather than listed, so budget for a step change rather than an extra seat charge.
