AesCode 8B
Microsoft's multimodal family turns content requirements and optional visual references into editable HTML/CSS documents. The 8B and 32B checkpoints derive from Qwen3-VL-8B-Instruct and Qwen3-VL-32B-Instruct respectively. They produce code, not raster images or video files. The reference provides composition and style, while the prompt remains the source of truth for text, figures and relationships. The verified public release is October 11, 2026; earlier repository creation is not its release date.

Slides, posters, dashboards and reports where tables and charts need to remain inspectable as code. The 8B variant is the smaller checkpoint; it uses SFT and 400 GDPO steps with seven reward channels. The provider measures a loss of just 1.00 Visual point when removing the reference for 8B: we do not transfer that figure to 32B. The card declares English and requires Transformers 4.57 or later.
The 24,576-token context and 12,000-token output belong to the published experiment. config.json declares 262,144 positions, but this does not establish evaluated quality at that limit. Likewise, two images allowed in the server example are not a universal guarantee. Generated HTML can contain scripts: review it and render it in an isolated environment without credentials or network access before publication. Do not confuse AesCode with the older AesCoder-4B or the AesCode-358K dataset.

The weights declare Apache 2.0; the official repository's code uses MIT. These are different licenses for different artifacts. We have not verified a hosted commercial API or token prices: numeric fields remain empty. Budget for GPU, memory, rendering and operations. The reference-creation pipeline may use external image and vision providers whose costs and terms are not included in the checkpoint.

05 / EVALUATIONS
How to read the results
“
Microsoft reports nine metrics on 300 infographics, averaging three generations per prompt without selecting the best. Rule combines Text, Bound and Chart; Visual combines Content, Layout and Style; Overall averages Rule and Visual. Recorded results use a visual reference, temperature 0.8 and top-p 0.95. They are not a general coding benchmark or independent Inferama tests. Full reproduction requires equivalent data and judges: the repository publishes code, not datasets.
| Benchmark | Result | Metric | Source |

| AesCode Infographics Text | 94,06 % | Percentage | View source ↗ |
| AesCode Infographics Bound | 88,36 % | Percentage | View source ↗ |
| AesCode Infographics Chart | 87,79 % | Percentage | View source ↗ |
| AesCode Infographics Rule | 90,07 % | Percentage | View source ↗ |

Inferama only highlights a “best result” when the metric, test set, configuration, and date allow for an equivalent comparison. The supplier's figures are presented as claims from its own source.
