 # Changelog
 
+## 2026-01-18 - 1.13.2 - fix(tests)
+stabilize OCR extraction tests and manage GPU containers
+
+- Add stopAllGpuContainers() and call it before starting GPU images to free GPU memory.
+- Remove PaddleOCR-VL image configs and associated ensure helpers from docker test helper to simplify images list.
+- Split invoice/bankstatement tests into two sequential stages: Stage 1 runs Nanonets OCR to produce markdown files, Stage 2 stops Nanonets and runs model extraction from saved markdown (avoids GPU contention).
+- Introduce temporary markdown directory handling and cleanup; add stopNanonets() and container running checks in tests.
+- Switch bank statement extraction model from qwen3:8b to gpt-oss:20b; add request timeout and improved logging/console output across tests.
+- Refactor extractWithConsensus and extraction functions to accept document identifiers, improve error messages and JSON extraction robustness.
+
+## 2026-01-18 - 1.13.1 - fix(image_support_files)
+remove PaddleOCR-VL server scripts from image_support_files
+
+- Deleted files: image_support_files/paddleocr_vl_full_server.py (approx. 636 lines) and image_support_files/paddleocr_vl_server.py (approx. 465 lines)
+- Cleanup/removal of legacy PaddleOCR-VL FastAPI server implementations — may affect users who relied on these local scripts
+
+## 2026-01-18 - 1.13.0 - feat(tests)
+revamp tests and remove legacy Dockerfiles: adopt JSON/consensus workflows, switch MiniCPM model, and delete deprecated Docker/test variants
+
+- Removed multiple Dockerfiles and related entrypoints for MiniCPM and PaddleOCR-VL (cpu/gpu/full), cleaning up legacy image recipes.
+- Pruned many older test files (combined, ministral3, paddleocr-vl, and several invoice/test variants) to consolidate the test suite.
+- Updated bank statement MiniCPM test: now uses MODEL='openbmb/minicpm-v4.5:q8_0', JSON per-page extraction prompt, consensus retry logic, expanded logging, and stricter result matching.
+- Updated invoice MiniCPM test: switched to a consensus flow (fast JSON pass + thinking pass), increased PDF conversion quality, endpoints migrated to chat-style API calls with image-in-message payloads, and improved finalization logic.
+- API usage changed from /api/generate to /api/chat with message-based payloads and embedded images — CI and local test runners will need model availability and possible pipeline adjustments.
+
 ## 2026-01-18 - 1.12.0 - feat(tests)
 switch vision tests to multi-query extraction (count then per-row/field queries) and add logging/summaries

+## Nanonets-OCR-s
+
+### Overview
+
+Nanonets-OCR-s is a Qwen2.5-VL-3B model fine-tuned specifically for document OCR tasks. It outputs structured markdown with semantic tags.
+
+**Key features:**
+- Based on Qwen2.5-VL-3B (~4B parameters)
+- Fine-tuned for document OCR
+- Outputs markdown with semantic HTML tags
+- ~8-10GB VRAM (fits comfortably in 16GB)
+
+### Docker Images
+
+| Tag | Description |
+|-----|-------------|
+| `nanonets-ocr` | GPU variant using vLLM (OpenAI-compatible API) |
+
+### API Endpoints (OpenAI-compatible via vLLM)
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/health` | GET | Health check |
+| `/v1/models` | GET | List available models |
+| `/v1/chat/completions` | POST | OpenAI-compatible chat completions |
+
+### Request/Response Format
+
+**POST /v1/chat/completions (OpenAI-compatible)**
+```json
+{
+  "model": "nanonets/Nanonets-OCR-s",
+  "messages": [
+    {
+      "role": "user",
+      "content": [
+        {"type": "image_url", "image_url": {"url": "data:image/png;base64,..."}},
+        {"type": "text", "text": "Extract the text from the above document..."}
+      ]
+    }
+  ],
+  "temperature": 0.0,
+  "max_tokens": 4096
+}
+```
+
+### Nanonets OCR Prompt
+
+The model is designed to work with a specific prompt format:
+```
+Extract the text from the above document as if you were reading it naturally.
+Return the tables in html format.
+Return the equations in LaTeX representation.
+If there is an image in the document and image caption is not present, add a small description inside <img></img> tag.
+Watermarks should be wrapped in brackets. Ex: <watermark>OFFICIAL COPY</watermark>.
+Page numbers should be wrapped in brackets. Ex: <page_number>14</page_number>.
+```
+
+### Performance
+
+- **GPU (vLLM)**: ~3-8 seconds per page
+- **VRAM usage**: ~8-10GB
+
+### Two-Stage Pipeline (Nanonets + Qwen3)
+
+The Nanonets tests use a two-stage pipeline:
+1. **Stage 1**: Nanonets-OCR-s converts images to markdown (via vLLM on port 8000)
+2. **Stage 2**: Qwen3 8B extracts structured JSON from markdown (via Ollama on port 11434)
+
+**GPU Limitation**: Both vLLM and Ollama require significant GPU memory. On a single GPU system:
+- Running both simultaneously causes memory contention
+- For single GPU: Run services sequentially (stop Nanonets before Qwen3)
+- For multi-GPU: Assign each service to a different GPU
+
+**Sequential Execution**:
+```bash
+# Step 1: Run Nanonets OCR (converts to markdown)
+docker start nanonets-test
+# ... perform OCR ...
+docker stop nanonets-test
+
+# Step 2: Run Qwen3 extraction (from markdown)
+docker start minicpm-test
+# ... extract JSON ...
+```

-- Usually alphanumeric, often starts with letters (e.g., R0014359508, INV-2024-001)

-- Look for labels: "Invoice Date", "Date", "Datum", "Rechnungsdatum", "Issue Date", "Bill Date"

-- Usually near the invoice number
-
-VENDOR NAME:
-- The company ISSUING the invoice (not the recipient)
-- Found in letterhead, logo area, or header - typically the largest/most prominent company name
-- Examples: "Hetzner Online GmbH", "Adobe Inc", "DigitalOcean LLC"
-
-CURRENCY:
-- Detect from symbols: € = EUR, $ = USD, £ = GBP
-- Or from text: "EUR", "USD", "GBP"
-- Default to EUR if unclear
-
-AMOUNTS (Critical - read carefully!):
-- total_amount: The FINAL amount due/payable - look for "Total", "Grand Total", "Amount Due", "Balance Due", "Gesamtbetrag", "Endbetrag"
-- net_amount: Subtotal BEFORE tax - look for "Subtotal", "Net", "Netto", "excl. VAT"
-- vat_amount: Tax amount - look for "VAT", "Tax", "MwSt", "USt", "19%", "20%"
