GPAI Model Provider Obligations

Understanding general-purpose AI model obligations under Articles 51-56 and how KlarvoEngine handles them.

GPAI Model Provider Obligations

If your AI system uses a foundation model (GPT, Claude, Gemini, Llama, etc.), KlarvoEngine automatically checks for GPAI-related obligations under Chapter V (Articles 51-56).

What Is a GPAI Model?

A general-purpose AI model is trained with large amounts of data using self-supervision at scale, displays significant generality, and can perform a wide range of tasks. The EU Commission's guidelines add a technical threshold: models trained with more than 10²³ FLOPs that generate language, images, or video.

GPAI models: GPT-4, Claude 3/4, Gemini, Llama, Mistral, DALL-E, Stable Diffusion

NOT GPAI: Weather models, protein folding, game AI, transcription-only models

Two Tiers

Tier 1 — All GPAI Providers (Article 53):

  • Technical documentation (Annex XI)
  • Downstream provider information (Annex XII)
  • Copyright policy
  • Training data summary publication
  • Cooperation with authorities
  • Tier 2 — Systemic Risk (Articles 51 + 55):

    Additional obligations for models trained above 10²⁵ FLOPs:

  • Model evaluation with adversarial testing
  • Systemic risk assessment and mitigation
  • Serious incident reporting
  • Cybersecurity for model and infrastructure
  • Commission notification within 2 weeks
  • What Klarvo Users Need to Do

    Most Klarvo users are DEPLOYERS, not GPAI providers. Your obligations:

  • Verify provider documentation — check your model provider supplied Annex XII docs
  • Check copyright policy — confirm provider has a published policy
  • Verify training data summary — check provider published this
  • Assess fine-tuning scope — if you fine-tuned, does your compute exceed 1/3 of original?
  • Document model version — record which version you use for traceability
  • When You Become a Provider

    You become a GPAI provider if:

  • You fine-tune with compute exceeding 1/3 of original training
  • You develop a GPAI model from scratch
  • You place a GPAI model on the EU market for the first time
  • You do NOT become a provider if:

  • You use a model via API (you're a deployer)
  • You do prompt engineering or RAG
  • You build an AI system on top of a model (you're an AI system provider)
  • KlarvoEngine Detection

    During classification, KlarvoEngine automatically:

  • Identifies if a GPAI model is mentioned in the description
  • Checks the model against known providers (OpenAI, Anthropic, Google, Meta, etc.)
  • Flags relevant GPAI obligations in your obligation list
  • Notes systemic risk status where known
  • Enforcement Timeline

  • GPAI obligations enforceable since August 2, 2025
  • GPAI fines applicable from August 2, 2026 (up to €15M or 3% turnover)
  • Pre-August 2025 models have until August 2, 2027 to comply
