To avoid subjectivity, "flagship LLM" will be any LLM that gets within 30 points of the top ranked LLM on trackingai's offline IQ test.

The advertisements must be a part of the model's response. Not a banner ad on the same webpage as the chatbot. Implicit advertisements count, like if the LLM "just happens" to recommend one company more often when asked for suggestions.

In order to resolve YES, there must be strong evidence that the advertising is intentional by the creator, or if the chatbot is agentic and cross-context, that it was paid or otherwise convinced directly to advertise. Simply observing a few instances where it seems particularly attached to one company isn't sufficient, since we'd expect that to happen by chance.

It does count if the LLM is advertising itself or its parent company, it doesn't have to be an advertisement that some other company purchases. But again it must be intentional, not just self-aggrandizing bias on the part of the LLM.
