Do coding agents recommend Vercel AI Gateway?
Vercel AI Gateway was chosen in 16% of 140 judged AI gateways sessions, ranking fourth. Measured with Claude Code, Codex and Cursor.
Vercel AI Gateway was chosen in 16% of 140 judged AI gateways sessions, ranking fourth. It was also raised as a candidate in 51 further sessions without being chosen.
This page reports what happened when Claude Code, Codex and Cursor had to solve a problem in AI gateways inside a realistic codebase. Not what a chat assistant says about Vercel AI Gateway. What an agent actually installed.

What this means
A solid second or third position in a category means the agent is genuinely choosing rather than reaching automatically. That is a winnable position, because the inputs it uses can be changed.
The fastest gains are usually in the sessions that were nearly won: read them, find the step where the agent moved on, and fix that step.
Where these numbers come from
The 140 sessions in AI gateways are part of a published set of 5,292, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: how we measured this.
Every AI gateways run can be replayed on the board.
If you work on Vercel AI Gateway: 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 Vercel AI Gateway?
Yes. Vercel AI Gateway was chosen in 22 of the 140 judged sessions in AI gateways, a 16% install share, ranking fourth in its category.
Does Claude Code recommend Vercel AI Gateway?
In 5 of the 45 sessions in AI gateways run with Claude Code, which is 11%.
Do different coding agents treat Vercel AI Gateway differently?
Yes, and by a wide margin. Codex chose it in 21% of its runs and Claude Code in 11%.
How was this measured?
Real coding agents at pinned versions were run in sandboxes inside 51 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 Vercel AI Gateway considered but not chosen?
It was raised as a candidate in 51 sessions without being chosen, and chosen in 22. That is a 30% conversion from considered to chosen.
Where this comes from
Armature ran 5,292 judged sessions with Claude Code, Codex and Cursor inside 51 realistic codebases, and published every run. The numbers on this page come from that work.
