+TinyLLaVA Qwen3 Standalone Model - Factory-Aligned Implementation
+================================================================
+
+This file contains a standalone implementation of TinyLLaVA specifically for Qwen3 models
+that replicates the behavior of the factory-based model system without requiring the full 
+factory infrastructure.
+
+KEY DIFFERENCES FROM STANDARD TINYLLAVA LIBRARY:
+==============================================
+
+1. QWEN3-SPECIFIC ARCHITECTURE:
+   - Uses Qwen3ForCausalLM as the language backbone
+   - Adapted for Qwen3's tokenization and attention patterns
+
+2. STANDALONE OPERATION:
+   - Self-contained model file that doesn't require tinyllava library installation
+   - Includes all necessary components: vision tower, connector, and language model
+   - Embeds prompt formatting logic directly (matches qwen3_base_template.py behavior)
+
+3. FACTORY ALIGNMENT:
+   - Replicates exact prompt formatting from tinyllava.data.template.qwen3_base_template
+   - Uses identical image processing pipeline as factory system
+   - Maintains same generation parameters and stopping criteria behavior
+
+4. HUGGINGFACE INTEGRATION:
+   - Designed for HuggingFace AutoModelForCausalLM.from_pretrained() loading
+   - Includes proper model registration and auto_map configuration
+   - Supports trust_remote_code=True loading pattern
+
+5. QWEN3 TOKENIZATION:
+   - Handles Qwen3's <|im_end|> tokens correctly (vs Llama's </s>)
+   - Uses pad_token_id=151643 and eos_token_id=151643 (Qwen3 specific)
+   - Adapted stopping criteria for Qwen3's token patterns
+
+USAGE:
+======
+model = AutoModelForCausalLM.from_pretrained(path, trust_remote_code=True)
+tokenizer = AutoTokenizer.from_pretrained(path)
+output, time = model.chat(prompt="Question?", image="path/url", tokenizer=tokenizer)
+
+This implementation enables seamless deployment of Qwen3-based TinyLLaVA models
+without requiring the full factory codebase dependencies.

+=============================================================================
+STEP-BY-STEP GUIDE: Creating a Factory-Aligned Standalone Model
+=============================================================================
+
+To convert a factory-based TinyLLaVA model to a standalone HuggingFace model
+that produces identical results, follow these steps:
+
+STEP 1: Copy Factory Template Logic
+===================================
+- Copy prompt formatting from tinyllava/data/template/llama_template.py
+- Key components:
+  * system message (exact text with trailing space)
+  * format_user = "USER: {{content}} "  
+  * format_assistant = "ASSISTANT: {{content}}</s>"
+  * format_image_token = "<image>\n{{content}}"
+
+STEP 2: Fix Critical Prompt Format Bug  
+======================================
+CRITICAL: The prompt MUST end with "ASSISTANT:" (NO SPACE)
+- Factory format: "...USER: <image>\nQuestion ASSISTANT:"
+- Wrong format: "...USER: <image>\nQuestion ASSISTANT: " (causes repetition)
+- This single space difference causes completely different generation behavior
+
+STEP 3: Add Stopping Criteria
+===============================
+Copy KeywordsStoppingCriteria from tinyllava.utils.eval_utils
+- Must stop at ["</s>"] tokens
+- Without stopping criteria, model generates infinite repetitive loops
+- Add to generate() call: stopping_criteria=[KeywordsStoppingCriteria(["</s>"], tokenizer, input_ids)]
+
+STEP 4: Fix Tokenization
+=========================  
+Copy tokenizer_image_token from tinyllava.data.template.base
+- Use _insert_separator (with underscore) function name
+- Handle BOS token offsets correctly
+- Process <image> tokens properly
+
+STEP 5: Fix Image Processing
+============================
+- Pass images as list: process_images([image], processor, config)
+- Handle both list and tensor return types
+- Apply proper device placement: .to(self.device)
+
+STEP 6: Add Output Cleaning
+===========================
+Clean outputs like factory does:
+```python
+outputs = outputs.strip()
+if outputs.endswith(stop_str):
+    outputs = outputs[:-len(stop_str)]
+outputs = outputs.strip()
+```
+
+STEP 7: Test and Validate
+=========================
+Compare outputs between factory and standalone:
+- Factory: python simply_inference.py
+- Standalone: python hugging_face_inference.py
+- Outputs should be nearly identical
+
+DEBUGGING CHECKLIST:
+====================
+□ Prompt ends with "ASSISTANT:" (no space)
+□ KeywordsStoppingCriteria added with ["</s>"]
+□ Images processed as [image] list
+□ _insert_separator function name used
+□ Output cleaning implemented
+□ Exact system message from factory template
+□ Generation parameters match factory
+
+RESULT COMPARISON:
+==================
+Before fixes: "1. Be cautious... 2. Wet and muddy... 3. Noisy... (repeats)"
+After fixes:  "When I visit the beach at the waterfront, I should be cautious about several things. First, I should be cautious about the water..." (matches factory)
+
+This documentation ensures future standalone models can be created without
+repeating the debugging process that identified these critical alignment issues.
