Ixian Runtime Licence

This licence governs the engines Ixian builds, the packages that carry them and the Ixian runtime inside them, from evaluation through to robots in production. It is part of the agreement between ZETICai, Inc. ("ZETIC") and the customer named in the workspace or Order ("Customer", "you"), alongside the Terms of Service. Words defined in the Terms mean the same here.

1. Definitions

• Engine: one model on one robot computer, built by Ixian and kept fast and verified, including a ready engine.
• Package: what Ixian delivers for an engine (an .ixpkg file or its contents). It holds two things:
  • the compiled engine (a compiled plan, which carries your trained weights) and the Ixian Runtime libraries, licensed under this licence;
  • a manifest and a report of your Customer Results (Terms of Service, section 6).
• Ixian Runtime: ZETIC's inference runtime, kernels and libraries included in or required by a Package, in object code.
• Robot Computer: the computer an engine is built for, such as NVIDIA Jetson AGX Orin or Qualcomm Dragonwing IQ9.
• Runtime Class: the class of a Robot Computer by its compute (XL, L, M or S), as the App's catalogue shows for each one.
• Licensed Robot: one unit of your product whose Robot Computer runs an engine.
• In Production: a Licensed Robot is in production in a Licence Year if, at any time in that year, it has been delivered to a customer of yours or is used in your operations, other than for development, testing or a pilot.
• Programme: one robot product line, or one deployment, that runs the same engines, as named in your Order or in the App.
• Licence Year: each 12-month period starting on the date in your Order, or on the date the first Licensed Robot of a Programme goes into production.
• Chipmaker's Stack: the Robot Computer vendor's own standard toolchain and runtime for the same model (for example NVIDIA TensorRT on Jetson, Qualcomm AI Runtime on Dragonwing), as measured in the engine's report.

1A. Who owns what

This licence follows the one rule in section 6 of the Terms of Service:

• ZETIC owns the Ixian Technology, or holds from its affiliates the right to license it. That includes the Ixian Runtime, and the code and structure of every compiled engine. ZETICai, Inc. is the licensor under this licence. This licence lets you use them; it transfers no ownership.
• You own your trained weights, wherever they appear, including inside a compiled engine, and your Customer Results in a package's report and manifest. Nothing in this licence restricts what you do with them.
• What a package does not contain. Packages contain the compiled engine and the Ixian Runtime, plus your Customer Results. They do not contain recipes, search or candidate records, sensitivity analyses or decision records. Those are not delivered, and this licence does not cover them.
• Audit. If you need to audit a result, ZETIC can show you how it was produced, on request, from its own records.

2. What you may do

While you comply with this licence and the Terms, ZETIC grants you a non-exclusive, non-transferable (except under section 17 of the Terms), worldwide licence, subject to section 10:

• to install and run Packages and the Ixian Runtime for evaluation, development, testing and pilots; and
• to install and run them on Licensed Robots in production as section 4 provides, and to distribute them in object code as part of those robots to your customers, who may use them only as part of the robot.

3. Evaluation, development and pilots

Engines built on the Free plan are for evaluation only and may not be used in production. On a paid plan, building, testing and evaluating engines, and running them in development and pilots, is covered by the plan.

4. The runtime licence

Fee. For each Licensed Robot in production in a Licence Year, you pay the yearly runtime licence for its Runtime Class, as listed in the App's price list (or your Order) at the start of that year. On 2026-11-13 the list is: XL US$1,000, L US$600, M US$300, S US$100 per robot per year. A robot counts once per Licence Year, however many engines it runs, at the class of its Robot Computer.

The first robots are free. The first [100] Licensed Robots of each Programme carry no fee.

Only for engines that earn it. The fee is owed only for robots whose engines are at least [1.3]× faster than the Chipmaker's Stack on the same Robot Computer, within the same accuracy budget, as the engine's report measures. A robot whose engines all fall short owes nothing for that Licence Year.

Paying once. Instead of yearly, you may pay [4] years' fee for a robot once. It licenses that robot for as long as it is in service, with rebuilds and re-verification for [5] years.

Renewals. The fee for a renewal year rises at most [20]% over the year before.

What it covers. For each Licensed Robot under a current licence: rebuilding and re-verifying its engines when the model (with the same architecture), JetPack or the board support package changes; a signed record of each engine version, kept for five years; and security fixes to the Ixian Runtime.

Reporting. Within [30] days after each calendar quarter, you report the number of Licensed Robots in production by Programme and Runtime Class. [Alternatively, a committed number of robots per year set in the Order.] We invoice [annually in advance, from your forecast, with a true-up after each quarter's report]. Fees are due under the Terms and exclude taxes.

Records and audit. You keep reasonable records of Licensed Robots for [3] years. Once a year, on [30] days' notice, an independent auditor bound by confidentiality may check them. If the audit finds an underpayment of more than 5%, you pay its reasonable cost as well as the shortfall.

Volume pricing may be agreed in an Order.

5. Restrictions

You may not, and may not let anyone else:

• use a Package with a model other than the one its engine was built for (including revisions made through Ixian), or use the Ixian Runtime apart from a Package;
• run a Package on a Robot Computer of a type other than the one it was built for;
• distribute a Package or the Ixian Runtime separately from a Licensed Robot, or make it available as a service to third parties;
• modify, reverse engineer, decompile or disassemble the Ixian Runtime or the code and structure of a Package's compiled plan, except to the extent the law allows despite this limit. Your own weights and Customer Results are not limited by this;
• remove or alter notices, the manifest or the report.

6. Your customers

When you distribute a Licensed Robot, the terms under which your customers receive the software must, as to the Package and the Ixian Runtime, be at least as protective of ZETIC and its licensors as sections 5, 9 and 10, and must disclaim liability on their behalf. You are responsible for your customers' compliance.

7. Third-party components

Packages include, or rely on, components licensed by others, listed in the Package's notices:

• NVIDIA. Packages for Jetson Robot Computers use NVIDIA libraries such as the TensorRT, CUDA and cuDNN runtimes. NVIDIA licenses them under its own agreements, and they may only be used on NVIDIA hardware. [Decision pending: whether Packages bundle these runtime files or use those installed with NVIDIA JetPack on the module; see docs/legal.md.] You must comply with NVIDIA's terms for the NVIDIA software on your robots.
• Qualcomm. Packages for Dragonwing Robot Computers use Qualcomm AI Runtime libraries, licensed by Qualcomm under its own terms.
• Open source. Open-source components are licensed under their own licences, which this licence does not restrict.
• Your model. Your model's own licence (for example AGPL-3.0, Llama or Gemma terms, OpenRAIL) continues to apply to your model inside the Package and may impose obligations on you and your customers. Meeting them is your responsibility under section 6 of the Terms.

8. Ready engines

A ready engine is an engine for a model whose architecture Ixian already has a recipe for, compiled with your weights without a search. It is bought once per model and Runtime Class, comes with [12] months of rebuilds for new checkpoints of the same architecture, and is refunded in full if it does not pass verification on your weights. Once in production it is covered by the runtime licence like any other engine.

9. Safety

The Ixian Runtime and Packages are not designed, tested or certified for use as the sole means of performing a safety function, or in systems whose failure could directly cause death, serious injury or severe damage, unless ZETIC agrees otherwise in writing. You are responsible for the functional safety, validation and certification of your robots. [ZETIC will not include any mechanism that stops a deployed robot from running a Package because of a licensing event; to confirm with the engine team.]

10. Export

You will comply with section 15 of the Terms for every Licensed Robot and every Package.

11. Warranty

For [90] days after a Package is delivered, it will perform materially as its report describes when run on the measured Robot Computer with the same software versions and inputs. Your sole remedy for a breach is for ZETIC to rebuild the engine or, if it cannot, to refund the runtime licence fees paid for the affected robots for the current Licence Year. Otherwise section 13 of the Terms applies.

12. Term and termination

This licence lasts as long as the Terms, and then, for each Licensed Robot, for the Licence Year paid, or for the life of the robot where it was paid once. If you do not pay runtime licence fees within [30] days of notice that they are overdue, or break section 5 and do not fix it within [30] days of notice, ZETIC may end your right to put further robots into production. Robots already in production keep running their Packages for the rest of the period paid for them. [Counsel to decide what happens to robots in the field after that.]

13. Liability

Section 14 of the Terms applies.
