The AI models we measure with
The AI models this report covers. New models are added over time and shown here.
These are the models our measurement asks about your company. We query them directly to see how they describe and recommend you. The set is chosen to cover the assistants people actually use, and we update it as the landscape changes.
Where shown, the percentage is how often a company is reflected in that model across the companies we have analysed.
When each model's knowledge ends
Each model is placed at the point in time its knowledge ends, grouped by provider and ordered oldest to newest. Models freeze their knowledge at different dates, so newer models can know more recent things about a company than older ones.

Anthropic acquired biotech startup Mithril Medicine to develop treatments for rare muscular dystrophies and accelerate drug discovery for cancer therapies and food allergies, partnering with firms including Bristol Myers Squibb. An internal Claude model produced a Lean 4 proof refuting the Exponential Time Hypothesis, while Anthropic and OpenAI both claim to have found algorithms challenging the hypothesis regarding 3-SAT.
Artificial Analysis updated its Intelligence Index, ranking Claude Opus 5.5 as the leader over GPT-6 Astra and GPT-6.1 Sol. Additionally, Anthropic released Claude Duet, and a study using Claude Opus 4.8 found that professional analysts often blindly adopt AI reasoning as their own.
