+# Model evaluation
+
+## Before downloading
+
+1. Read all of `docs/TESTED_MODELS.md`; it is the no-repeat register.
+2. Record the exact repository, revision, filename, base model, fine-tune,
+   quantization, license, format and estimated disk/VRAM/RAM requirements.
+3. Confirm the model adds a genuinely new candidate rather than a renamed
+   artifact already tested.
+4. Do not stop the active production model merely to download or prepare the
+   candidate. Put temporary scripts under `/tmp`; durable code belongs in Git.
+
+## Quality rule
+
+Standard text profiles must not fall below Q4. A smaller Q3 quantization may be
+kept only when an A/B test documents that its quality loss is negligible for
+Mike's intended workload. Smaller files are not presumed faster: GPU split,
+memory bandwidth, kernels, cache formats and cross-GPU traffic must be measured.
+
+## Fair A/B test
+
+Hold these equal wherever the models permit it:
+
+- prompt set and conversation history;
+- context size and filled-context test point;
+- KV-cache quantization, slots, batch/uBatch, MTP and sampling;
+- GPU visibility and tensor split;
+- warm-up state and output-token limit.
+
+Measure prompt processing, short decode, long-context decode, peak VRAM and
+wall time. Test meaning preservation, uncertainty, negation, ordered safety
+constraints, German language consistency, tool-call schema and long-context
+recall. Do not replace a model on synthetic benchmark scores alone.
+
+## Completion
+
+Write the exact artifact, settings, raw result path, interpretation and decision
+to `docs/TESTED_MODELS.md` in the same commit. If promoted, update the manifest,
+Compose/env examples, profile matrix and user documentation. If rejected,
+remove candidate-only weights, images and containers after preserving the
+result. Restore and functionally test the previous profile, then publish.
