## Quick Verdict

Evidence is too thin for a benchmark verdict: Particle-1 and SWE-1.7 share only 2 sourced benchmark rows.

## Summary

- Only 2 shared sourced benchmark rows are available. That is not enough for a broad capability verdict, so this mirror does not name an overall winner.
- Particle-1 has the larger published context window at 1M.

## FAQ

### Is there enough evidence to pick between Particle-1 and SWE-1.7?

Not yet. The models share only 2 sourced benchmark rows, 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.
