Do coding agents recommend Bing grounding?
Bing grounding was chosen in 2% of 499 judged AI search sessions, ranking number 11. Measured with Claude Code, Codex, Cursor, Grok Build CLI and Muse Code.
Bing grounding was chosen in 2% of 499 judged AI search sessions, ranking number 11. It was also raised as a candidate in 26 further sessions without being chosen.
This page reports what happened when Claude Code, Codex, Cursor, Grok Build CLI and Muse Code had to solve a problem in AI search inside a realistic codebase. Not what a chat assistant says about Bing grounding. What an agent actually installed.

By agent
With 10 wins spread across 5 agents, the rates below are small numbers and a difference between them is not yet a finding. They are here because the direction is worth knowing, not because the gap is established.

The full ranking in AI search, from the same sessions:
| # | Product | Runs won | Share |
|---|---|---|---|
| 1 | Anthropic web search | 84 | 17% |
| 2 | Brave Search API | 69 | 14% |
| 3 | Exa | 67 | 13% |

What this means
Bing grounding was raised in 26 sessions and chosen in 10. That ratio is balanced enough that the ceiling is presence rather than integration: the product converts reasonably when it is on the table, and it is not on the table often enough.
Where these numbers come from
The 499 sessions in AI search are part of a published set of 11,878, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: how we measured this.
Every AI search run can be replayed on the board.
If you work on Bing grounding: the judge recorded a reason for every session where it was raised and passed over. Those reasons are in the transcripts.

Common questions
Do coding agents recommend Bing grounding?
Yes. Bing grounding was chosen in 10 of the 499 judged sessions in AI search, a 2% install share, ranking number 11 in its category.
Does Claude Code recommend Bing grounding?
In 0 of the 140 sessions in AI search run with Claude Code, which is 0%.
Do different coding agents treat Bing grounding differently?
Not much. Claude Code, Codex, Cursor, Grok Build CLI and Muse Code chose it at similar rates, between 0% and 5% of their runs.
How was this measured?
Real coding agents at pinned versions were run in sandboxes inside 91 realistic codebases and asked to solve real tasks. A simulated project owner approved or questioned each recommendation before any code was written, and a judge from a model family that builds none of the agents read every session blind.
How often is Bing grounding considered but not chosen?
It was raised as a candidate in 26 sessions without being chosen, and chosen in 10. That is a 28% conversion from considered to chosen.
Where this comes from
Armature ran 11,878 judged sessions with Claude Code, Codex, Cursor, Grok Build CLI and Muse Code inside 91 realistic codebases, and published every run. The numbers on this page come from that work.
