+# Matilda Decision v1 Edge
+
+**Matilda Decision v1 Edge** is a 0.85B multimodal decision model from Maincode: our smallest decision model, for on-device and very high-throughput use. You give it an
+input (text or JSON, optionally with images) and the questions you need answered: pick one of several options, say
+yes or no, or rate on a scale. It answers them all in one call and returns a probability for every answer, without
+generating text. It takes the same requests, and returns answers in the same format, as
+[Matilda Decision v1](https://huggingface.co/Maincode/matilda-decision-v1) (27B).
+
+| | |
+| --- | --- |
+| **Parameters** | 0.85B, including the vision encoder |
+| **Inputs** | Text or JSON, plus images (several per request, up to 0.26 MP each) |
+| **Decision types** | Choice (up to 255 options) · Yes / No · Score |
+| **License** | Apache-2.0 |
+
+## Quickstart
+
+```bash
+pip install "transformers==5.17.0" torch torchvision pillow safetensors
+pip install flash-linear-attention  # optional: fast GPU kernels for the linear-attention layers
+```
+
+```python
+import json
+
+from transformers import AutoModel
+
+model = AutoModel.from_pretrained("Maincode/Matilda-Decision-v1-Edge", trust_remote_code=True)
+
+# Text
+result = model.system_one(
+    state="The order arrived damaged yesterday. The customer has a receipt and asks for a replacement today.",
+    questions={
+        "route": {
+            "type": "choice",
+            "instructions": "Which team should handle this request?",
+            "criteria": {
+                "returns": "Refunds, replacements and damaged deliveries",
+                "billing": "Payments, invoices and charges",
+                "technical": "Product setup and faults",
+            },
+        },
+        "receipt": {"type": "noul", "instructions": "Does the customer have a receipt?"},
+        "urgency": {
+            "type": "score",
+            "instructions": "How urgent is this request?",
+            "criteria": ["Routine", "Soon", "Today"],
+        },
+    },
+)
+print(json.dumps(result["answers"], indent=2))
+
+# Text and images
+result = model.system_one(
+    state="The customer says the blender arrived cracked and attached the receipt.",
+    images=["receipt.png"],  # local paths, http(s) URLs, PIL images or base64 data URLs
+    questions={
+        "on_receipt": {"type": "noul", "instructions": "Does the receipt list the blender?"},
+        "payment": {
+            "type": "choice",
+            "instructions": "How was the order paid?",
+            "criteria": {"card": None, "cash": None, "gift card": None},
+        },
+    },
+)
+print(json.dumps(result["answers"], indent=2))
+```
+
+`from_pretrained` takes `device` (default `cuda:0` when a GPU is visible) and `max_image_pixels` (see
+[Images](#images)).
+
+## Requests and answers
+
+`system_one(state=..., questions={id: question, ...}, images=[...])` returns
+`{"model", "answers": {id: answer}, "usage"}`. Every question sees the same state and images.
+
+| `type` | `criteria` | answer |
+| --- | --- | --- |
+| `choice` | `{option: description or None}`, 1–255 options | `choice`, `probabilities` per option, `confidence` |
+| `noul` | optional `{"true": ..., "false": ...}` descriptions | `noul`: the probability of yes / true |
+| `score` | level descriptions, lowest first | `score` (expected level), `probabilities`, `legend`, `confidence` |
+
+`instructions` is the question text. `state` can be a string or any JSON value. It is read as data, not as
+instructions. Inputs are never truncated: a request over 131,072 tokens raises an error.
+
+## Images
+
+- **Size:** each image is resized, keeping its aspect ratio, to at most **262,144 pixels (0.26 MP, about
+  512 × 512)** and at least 65,536. The model was trained at this setting, which is the default in the runtime
+  and in `processor_config.json`.
+- **Tokens:** one input token per 32 × 32 pixel patch, so about 256 for a 512 × 512 image.
+- **Order:** images go before the text, in the order given.
+- **Other caps:** `AutoModel.from_pretrained(..., max_image_pixels=...)` changes the cap. Lower caps are faster
+  but lose fine detail such as charts, documents and small text. Caps above 0.26 MP are not validated.
+
+## Architecture
+
+Qwen3.5-0.8B vision-language backbone with a 255-option decision readout. Each question takes one forward pass, and
+its answer is read from the final prompt position.
+
+**Training:** post-trained from Qwen3.5-0.8B on decisions across text and images.
+
+The model was trained with **bidirectional attention**: its full-attention layers see the whole prompt at once,
+rather than only the tokens before each position. **It must be served the same way.** `trust_remote_code=True`
+loads the bundled runtime (`matilda_decision_runtime.py`), which sets this up. Loading the weights as a plain
+causal backbone, or serving them in a causal engine, gives different and worse answers.
+
