## Quick Verdict

Evidence is too thin for a benchmark verdict: GLM-5.2 and GPT-4.1 share only 1 sourced benchmark row.

## Summary

- Only 1 shared sourced benchmark row is available. That is not enough for a broad capability verdict, so this mirror does not name an overall winner.
- GLM-5.2 has the lower published output-token price.

## FAQ

### Is there enough evidence to pick between GLM-5.2 and GPT-4.1?

Not yet. The models share only 1 sourced benchmark row, so this mirror reports the available measurements and metadata without naming a broad winner.

### What can I compare safely on this page?

Published pricing, context windows, model type, and individual shared benchmark rows are directly comparable. Independent overall scores and non-overlapping benchmark coverage are labeled separately and should not be read as a controlled head-to-head result.
