# COSMOS 9B V1 (Base Merge)

COSMOS 9B V1 is a merged base model combining the advanced reasoning and massive context window of Qwythos-9B with the agentic coding capabilities of OmniCoder-9B.

## Merge Details

### Merge Method
This model was merged using a custom DARE-TIES implementation (50% density, 50% weight) to preserve the distinct specializations of both parent models.

### Models Merged
- **[empero-ai/Qwythos-9B-Claude-Mythos-5-1M]**: A full-parameter reasoning model post-trained on Claude Mythos traces with a 1,048,576-token context window (YaRN).
- **[Tesslate/OmniCoder-9B]**: A coding agent model fine-tuned on 425,000+ curated agentic coding trajectories from Claude Opus 4.6.

### Configuration
The merge was anchored to the Qwythos-9B base to strictly preserve the YaRN 1M context window, native function calling, and the Qwen3.5 hybrid architecture (Gated Delta Networks).

## Intended Use
This is a base merge intended for further fine-tuning, specifically for educational purposes, programming instruction (C/C++), and Portuguese language specialization.
