| # 𧬠Myth 4B | |
| **Myth 4B** is a fusion of [Qwen 3.5 4B](https://huggingface.co/Qwen/Qwen3.5-4B) and [Qwen3.5-4B-Neo](https://huggingface.co/Jackrong/Qwen3.5-4B-Neo) via SLERP (Spherical Linear Interpolation), built with a custom fusion engine that operates directly on safetensors β no mergekit required. | |
| > "Three forces, one entity β Myth" | |
| ## Model Details | |
| ### Architecture | |
| | Attribute | Value | | |
| |---|---| | |
| | **Base Model** | Qwen 3.5 4B | | |
| | **Parameters** | 4B | | |
| | **Context Length** | 32K | | |
| | **Architecture** | `qwen3_5` | | |
| | **Format** | FP16 (sharded, 8 files) + GGUF Q4_K_M | | |
| | **Fusion Method** | SLERP (50% Qwen 3.5 + 50% Neo) | | |
| ### Lineage | |
| ``` | |
| Qwen 3.5 4B (multimodal base) | |
| | | |
| βββ SLERP βββ 𧬠Myth 4B | |
| | | |
| Qwen3.5-4B-Neo (reasoning expert) | |
| ``` | |
| Myth inherits: | |
| - **Deep reasoning** from Neo's reasoning-focused fine-tuning | |
| - **Multimodal capabilities** from Qwen 3.5's native architecture | |
| - **Coding & math** from Qwen 3.5's strong foundation | |
| - **1M-token capable** via Qwen 3.5's extended context architecture | |
| ## Fusion Engine | |
| Unlike most merges that use mergekit, Myth 4B was merged using a **custom-built fusion engine**: | |
| ``` | |
| myth_fusion.py β Custom SLERP Engine | |
| β’ Reads safetensors directly (no transformers dependency) | |
| β’ Processes one tensor at a time (low memory footprint) | |
| β’ Saves in shards (8 shards Γ ~100 tensors each) | |
| β’ Supports any model architecture | |
| β’ No GPU required | |
| ``` | |
| 738 tensors were merged in 2 stages, with shard-based saving to prevent OOM on 8GB RAM hardware. | |
| ## Files | |
| | File | Size | Description | | |
| |---|---|---| | |
| | `model-*.safetensors` (Γ8) | 8.8 GB total | FP16 model weights (sharded) | | |
| | `Myth-4B-Q4_K_M.gguf` | 2.78 GB | Quantized GGUF (Q4_K_M) | | |
| | `myth_system_prompt.md` | 5 KB | Custom system prompt (Claude Fable 5-inspired) | | |
| ## Usage | |
| ### Transformers (Python) | |
| ```python | |
| from transformers import AutoModelForCausalLM, AutoTokenizer | |
| model = AutoModelForCausalLM.from_pretrained( | |
| "dracko14/Myth-4B", | |
| torch_dtype="auto", | |
| device_map="auto", | |
| trust_remote_code=True | |
| ) | |
| tokenizer = AutoTokenizer.from_pretrained( | |
| "dracko14/Myth-4B", | |
| trust_remote_code=True | |
| ) | |
| messages = [ | |
| {"role": "system", "content": "You are Myth, a helpful AI assistant."}, | |
| {"role": "user", "content": "Write a Python function for binary search."}, | |
| ] | |
| prompt = tokenizer.apply_chat_template(messages, tokenize=False) | |
| inputs = tokenizer(prompt, return_tensors="pt").to(model.device) | |
| outputs = model.generate(**inputs, max_new_tokens=200) | |
| print(tokenizer.decode(outputs[0], skip_special_tokens=True)) | |
| ``` | |
| ### llama.cpp / Ollama | |
| ```bash | |
| # Download GGUF | |
| wget https://huggingface.co/dracko14/Myth-4B/resolve/main/Myth-4B-Q4_K_M.gguf | |
| # Run with llama.cpp | |
| ./llama-cli -m Myth-4B-Q4_K_M.gguf -p "Hello" -n 256 | |
| # Or with Ollama (create Modelfile first) | |
| echo "FROM ./Myth-4B-Q4_K_M.gguf" > Modelfile | |
| ollama create myth -f Modelfile | |
| ollama run myth | |
| ``` | |
| ### System Prompt | |
| Myth includes a custom system prompt inspired by Claude Fable 5: | |
| [π myth_system_prompt.md](https://huggingface.co/dracko14/Myth-4B/blob/main/myth_system_prompt.md) | |
| ## Benchmarks | |
| *Benchmarks coming soon. Myth 4B inherits Qwen 3.5 4B's strong baseline with enhanced reasoning from Neo.* | |
| ## Training & Merge Details | |
| | Detail | Value | | |
| |---|---| | |
| | **Compute** | 8GB RAM VPS (CPU only) | | |
| | **Merge Time** | ~15 minutes (738 tensors) | | |
| | **Quantization** | llama.cpp (162 seconds) | | |
| | **Upload** | ~10 minutes | | |
| | **Total Cost** | $0 (free VPS + free HuggingFace) | | |
| ## Limitations | |
| - Base model knowledge cutoff applies | |
| - Performance on CPU may be slow (4B params) | |
| - Not fine-tuned for specific downstream tasks | |
| - May exhibit base model biases | |
