One field, one race, sitting fifth with room to climb.
Where it wins. In LLM & Agent Evals, Arize AI earns a 36% mention rate, meaning models surface it in more than a third of relevant buying conversations. The 'Enterprise pick' prompt theme confirms it registers as a credible option when buyers frame the question around scale.
Where it loses. A 12.5% first-pick rate against 14 rivals means it trails whatever sits above it in the same category, and the complete absence from startup and small-team conversations hands those buyers to Langfuse and LangSmith before Arize enters the frame.
