Microsoft RAI benchmark: Ungroundedness
phi-3-medium 14B 0.21 leads since August 2024 Models answer in GPT-4 simulated multi-turn conversations. A judge rates how ungrounded each answer is in the given prompt, from 0 to 4.
In-house Microsoft evaluation from the Phi-3 report. The Phi-4 report uses a Grounding score from 0 to 5 instead.

phi-3-medium 14B leads with 0.21 among models released by August 2024
Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.
The newest model with a score here came out in August 2024, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:
- Claude Fable 5.2
-
Gemini 4 Carbon - GPT-6 Astra
- Claude Opus 5.5
- and 16 more
- 1 phi-3-medium 14B 0.21

- 3 phi-3-small 7.4B 0.30
- 4 phi-3-mini 3.8B 0.60

Labs report it only in system cards
We read the headline results of 522 launch posts from 52 labs, and none of them list this benchmark. Some system cards do, below.
4 system cards report it, from 1 lab
Besides launch posts, we read the system cards, model cards and technical reports labs publish with a release. They report far more, including safety and frontier-risk tests.
