Orbit-SpaceStar-0.01

🛰️ Orbit — 0.01

Orbit Ultra is a compact, built-from-scratch Causal Language Model based on the classic Transformer architecture. The model has been trained locally and optimized to handle specific logical reasoning tasks, mathematical patterns, and interactive dialogues using a built-in Chain of Thought (CoT) loop.

Thanks to an advanced procedural data engine, Orbit learns abstract logic and the Copy Mechanism via attention routing, rather than simply memorizing static phrases.

🔥 Key Features

1. Live Chain of Thought (CoT) Stream

Orbit is trained to think before it speaks. Every interaction generates an internal thought process encapsulated within a <|thought|> tag. In this sandbox, the model analyzes the prompt, writes down mathematical steps, or walks through logical inferences before formulating its final response.

2. In-Context Attention & Copy Mechanism

Due to the dynamic and perfectly balanced synthetic dataset, the model avoids overfitting on specific training examples. Its attention heads are tuned to actively extract variables (such as names in logical riddles or digits in math problems) directly from your prompt and inject them correctly into the output.

📂 File Structure

To function properly (e.g., within a Hugging Face Space or a local inference environment), this model requires the following core files in the repository:

• best_model.pth — The trained matrix weights of the model.
• vocab.json — The BPE vocabulary dictionary.
• merges.txt — The BPE merge rules for tokenization.
• app.py — The Gradio / Flask script powering the interface.
