Artificial Analysis Openness Index

A composite measure providing an industry standard to communicate model openness for users and developers.
See example tasks

The Artificial Analysis Openness Index assesses how 'open' models are on the basis of their availability and transparency across different components (e.g. models weights, training data, and model architecture).
Availability represents the ability to use a model via API, self-hosting through open weights, and use freely with permissive licensing. Transparency captures the degree to which a model's methodology and data have been disclosed, shared, and permissively licensed for the community to use to understand a model's inputs and replicate or build on its approach.

All evaluations are conducted independently by Artificial Analysis. More information can be found on our Intelligence Benchmarking Methodology page.

Transparency vs. Availability

Artificial Analysis Openness Index: Model Availability vs. Model Transparency

Model availability reflects the availability of a model for usage and associated license (maximum 6 points) · Model transparency reflects methodology and data disclosures, data sharing, and code and licensing associated with a model's training process (maximum 12 points)

Scoring methodology

Each component is scored on a 0-3 qualitative scale based on the best-fitting openness 'archetype', with each model assessed based on the full set of public first-party information available.

We synthesize these underlying factors into a unified metric, the Artificial Analysis Openness Index, as follows:

  • Data elements are averaged between pre- and post-training (to give a total of 6 possible points across data)
  • All component scores are added (up to a maximum of 18/18 points)
  • This score is normalized to a 0-100 scale

Where models are derived from a third-party base model, they may be constrained by the licensing or limited disclosure of the upstream model. For incremental/update releases, we only consider disclosures explicitly about the new release (including allowing model creators to declare which components remain consistent with an earlier release).

Frequently Asked Questions

The Artificial Analysis Openness Index is a composite score that measures how openly available and transparently documented AI models are, including model weights, licensing, training data, training methodology, and training code.

The Artificial Analysis Openness Index scores models on a qualitative 0 to 3 scale across model availability (weights access and license) and model transparency (training data access and license, methodology disclosure, and training pipeline release). Data scores are averaged between pre- and post-training, and the component scores are summed to a maximum of 18, then normalized to a 0 to 100 scale.

Molmo 7B-D currently has the highest Artificial Analysis Openness Index score, with a score of 89 among models with published Openness Index results. View model

Open and transparent models support reproducibility, independent evaluation, customization for specific use cases, and commercial use without lock-in. The Artificial Analysis Openness Index gives a single comparable score for how open a model is, so users can weigh openness alongside intelligence, speed, and price when choosing a model.

No. Open weights means the model weights are available, but it does not guarantee that source code, training data, training recipes, or permissive licenses are available. The Artificial Analysis Openness Index scores these factors separately to distinguish models that are accessible from models that are broadly open and transparent.
