chandra-ocr-2-oq2-mlx is a image-text-to-text model from 1qh. Use it for the image-text-to-text task on the model card, and read the license before you ship it in a product. It is set up for mlx. The card lists the license as apache-2.0.

1qh/chandra-ocr-2-oq2-mlx
datalab-to/chandra-ocr-2 quantized with oQ (oMLX v0.5.3) at level 2.0,
data-driven mixed precision: oQ measures each layer's quantization error through calibration and
allocates bits where the measurement says they matter, rather than by a fixed per-tensor rule.
| Base | datalab-to/chandra-ocr-2 |
| oQ level | 2.0 (effective ~2.8–3.0 bits/weight) |
| Size | 2.3 GB (from 9.1 GB bf16) |
| Sensitivity entries | 248 |
| oMLX | v0.5.3 |
Table-column fidelity: PARTIAL / unstable. On the OCR fidelity check this build produced a correct table on one page and an unreadable one on another, with no column shift observed. Table output is unreliable at this level; prefer 2.5 or 5+ when structure matters.
Vision weights are kept fp16; only the language tower is quantized.
