Development measurements
How long does local take?
Sharpen (Tikhonov), ten runs per image on an Intel Core i9-13900HX with 32 GB RAM in September 2026.
| Image size | Measured processing time |
|---|---|
| 1.6 MP · 1536 × 1038 | 0.59–0.63 seconds |
| 25.1 MP · 6160 × 4080 | 11.9–17.2 seconds |
These are native sharpening measurements, not end-to-end AI timings. Performance depends on image dimensions and available memory. AI performance will be reported separately.
