The practical trade-offs
Documented strengths
- SWE-bench Pro 65.7% at $0.834/$2.501 is outstanding price-performance
- Apache 2.0 with FP8 weights on four mirrors - the most permissive frontier-scale open release here
- Arena WebDev Frontend rank 10 (1638) despite preview status
- 1M+ context with sparse attention designed for long-horizon dev work
Limitations to check
- Preview-labelled: no GA commitment, and no AA coverage for independent speed/intelligence measurement
- Modalities are not documented on the fetched pages
- Only 1,330 Arena votes (+/-18)
- Serving needs 8-way tensor parallelism; single-provider hosting on OpenRouter

- Exact row hy4-preview; source results dated 2026-09-05; human preference; confidence interval +/-18; 1330 votes; preliminary. This is a checked source snapshot, not a newly run September 8 evaluation.
Source reports, measured results, and editorial assessments are separate evidence types. Source dates do not imply a new benchmark run. Capture dates are shown when recorded; otherwise we say the capture date was not recorded. Recorded dates are compared with this catalogue snapshot (Sep 11, 2026), not today’s date.
