GMLP: what it requires, and the records to keep

Ten guiding principles issued by the FDA, Health Canada and the UK MHRA in October 2021 for developing safe, effective machine-learning medical devices across the total product lifecycle. IMDRF finalized a near-identical international version in January 2025, and FDA people reviewing it use the same concepts when assessing AI-enabled device submissions.

01 / What it requires

What GMLP requires

Manufacturers developing AI/machine-learning-enabled medical devices for the US, Canadian and UK markets, and the regulators reviewing them.

  1. 01Use multidisciplinary expertise throughout the total product lifecycle and follow good software engineering and security practices.
  2. 02Use clinical study participants and data sets representative of the intended patient population.
  3. 03Keep training data sets independent of test sets, and base reference datasets on best available methods.
  4. 04Tailor model design to the available data and intended use, and evaluate performance of the human-AI team.
  5. 05Test device performance under clinically relevant conditions and give users clear, essential information.
  6. 06Monitor deployed models for performance and manage retraining risks.

02 / AI work

Where it touches AI work

AI-specific. The principles were written for medical devices that use machine learning, including models that are retrained or updated after release.

04 / Enforcement

Who enforces it

None directly; the principles are not binding. FDA, Health Canada and MHRA apply related expectations through device premarket review and quality-system rules.

05 / Records

Records an organisation keeps

What an auditor or an inquiry usually asks to see. Your obligations depend on your role and your facts.

  1. 01Dataset documentation showing representativeness and train/test separation
  2. 02Reference standard (ground truth) method and rationale
  3. 03Clinical performance testing report under intended-use conditions
  4. 04Post-market performance monitoring plan and retraining change records

Optional evidence · where Planisphere fits

Keep a record anyone can check

When your team meets a duty, Planisphere can seal the event it reports as a receipt.

01 · Your teamRecord the event

A disclosure shown, a review signed, a model change approved: the event your system reports.

02 · PlanisphereSeal it

The event becomes a sealed receipt, dated and attributed to whoever is signed in.

03 · AnyoneCheck it

Paste the receipt into Verify. No account or key.

A record supports your compliance evidence process. It is not a legal finding or a certification. Systems that call Planisphere's gate API can also hold or refuse an action before it runs.

QUESTIONS

The questions that come next

What are the 10 Good Machine Learning Practice (GMLP) principles?+

The 10 principles, published by FDA, Health Canada and the UK MHRA in October 2021, are: multidisciplinary expertise across the product life cycle; good software engineering and security practices; clinical study participants and data sets representative of the intended patients; training data independent of test sets; reference datasets based on best available methods; model design tailored to the data and intended use; focus on human-AI team performance; testing under clinically relevant conditions; clear, essential information for users; and monitoring deployed models while managing retraining risks. They are principles, not a checklist. IMDRF issued a near-identical final version in January 2025. Read the full answer
