+
+## Overview
+
+**OmniCoder-9B** is a 9-billion parameter coding agent model built by [Tesslate](https://tesslate.com), fine-tuned on top of [Qwen3.5-9B](https://huggingface.co/Qwen/Qwen3.5-9B)'s hybrid architecture (Gated Delta Networks interleaved with standard attention). It was trained on **425,000+ curated agentic coding trajectories** spanning real-world software engineering tasks, tool use, terminal operations, and multi-step reasoning.
+
+The training data was specifically built from **Claude Opus 4.6 agentic and coding reasoning traces**, targeting scaffolding patterns from Claude Code, OpenCode, Codex, and Droid. The dataset includes successful trajectories from models like Claude Opus 4.6, GPT-5.4, GPT-5.3-Codex, and Gemini 3.1 Pro.
+
+The model shows strong agentic behavior: it recovers from errors (read-before-write), responds to LSP diagnostics, and uses proper edit diffs instead of full rewrites. These patterns were learned directly from the real-world agent trajectories it was trained on.
+
+### Key Features
+
+- **Trained on Frontier Agent Traces** : Built from Claude Opus 4.6, GPT-5.3-Codex, GPT-5.4, and Gemini 3.1 Pro agentic coding trajectories across Claude Code, OpenCode, Codex, and Droid scaffolding
+- **Hybrid Architecture** : Inherits Qwen3.5's Gated Delta Networks interleaved with standard attention for efficient long-context processing
+- **262K Native Context** : Full 262,144 token context window, extensible to 1M+
+- **Error Recovery** : Learns read-before-write patterns, responds to LSP diagnostics, and applies minimal edit diffs instead of full rewrites
+- **Thinking Mode** : Supports `<think>...</think>` reasoning chains for complex problem decomposition
+- **Apache 2.0** : Fully open weights, no restrictions

+## Quickstart
+
+### Transformers
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model_id = "Tesslate/OmniCoder-9B"
+
+tokenizer = AutoTokenizer.from_pretrained(model_id)
+model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype="auto", device_map="auto")
+
+messages = [
+    {"role": "system", "content": "You are a helpful coding assistant."},
+    {"role": "user", "content": "Write a Python function to find the longest common subsequence of two strings."},
+]
+
+text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+inputs = tokenizer([text], return_tensors="pt").to(model.device)
+
+outputs = model.generate(**inputs, max_new_tokens=2048, temperature=0.6, top_p=0.95, top_k=20)
+print(tokenizer.decode(outputs[0][inputs.input_ids.shape[-1]:], skip_special_tokens=True))
+```
+
+### vLLM
+
+```bash
+vllm serve Tesslate/OmniCoder-9B --tensor-parallel-size 1 --max-model-len 65536
+```
+
+```python
+from openai import OpenAI
+
+client = OpenAI(base_url="http://localhost:8000/v1", api_key="token")
+response = client.chat.completions.create(
+    model="Tesslate/OmniCoder-9B",
+    messages=[{"role": "user", "content": "Explain the difference between a mutex and a semaphore."}],
+    temperature=0.6,
+)
+print(response.choices[0].message.content)
+```

+
+## Training Details
+
+| | |
+|:---|:---|
+| **Base Model** | [Qwen3.5-9B](https://huggingface.co/Qwen/Qwen3.5-9B) |
+| **Method** | LoRA SFT (r=64, alpha=32) |
+| **Dataset** | 425K agentic trajectories from 5 sources |
+| **Packing** | Sample packing with 99.35% efficiency |
+| **Hardware** | 4x NVIDIA H200 (DDP) |
+| **Framework** | Axolotl |
+| **Precision** | bf16 |
+| **Optimizer** | AdamW (lr=2e-4, cosine schedule) |
+
+---
+
+## Architecture
+
+OmniCoder inherits Qwen3.5-9B's hybrid architecture:
+
+- **Gated Delta Networks** : Linear attention layers interleaved with standard attention for efficient long-range dependencies
+- **VLM Backbone** : Built on `Qwen3_5ForConditionalGeneration`
+
+---
+
+## Recommended Sampling Parameters
+
+| Parameter | Value |
+|:---|:---|
+| Temperature | 0.6 |
+| Top-P | 0.95 |
+| Top-K | 20 |
+| Presence Penalty | 0.0 |
+
+For agentic / tool-calling tasks, consider lower temperature (0.2-0.4) for more deterministic behavior.
+
+---
+
+## Limitations
+
+- Performance on non-English tasks has not been extensively evaluated
+- Tool-calling format is flexible but works best with the scaffolding patterns seen in training
