0zhr is an open conversational language model designed for reasoning, long-form dialogue, and tool-aware agent workflows.
Unlike lightweight chat models optimized only for response speed, 0zhr is designed to spend additional computation on planning, structured reasoning, and maintaining coherent conversations across longer interactions.
Source code & release:github.com/0penAGI/0pen — dataset pipeline, LoRA training script (lora.py), adapter weights, and GGUF conversion.
Highlights
🧠 Thinking / reasoning capable
🔧 Designed for tool calling workflows
💬 Strong conversational abilities
🌍 Multilingual (English + Russian)
📚 Long-form explanations
🤝 Natural dialogue style
⚡ Optimized for local inference
Philosophy
0zhr was trained with a focus on dialogue quality rather than benchmark optimization alone.
The goal is to produce responses that remain coherent during long conversations, reason before answering when appropriate, and integrate naturally into agent systems.

Why does this mathematical proof fail?
0zhr
The proof becomes invalid when it divides by (a - b). Since the assumption is a = b, we have (a - b) = 0, making that step a division by zero. Every step after that no longer follows logically.
