Group Model

This is a merge of pre-trained language models created using mergekit.

Merge Details

Merge Method

This model was merged using the TIES merge method using Qwen/Qwen3-1.7B as a base.

Models Merged

The following models were included in the merge:

Configuration

The following YAML configuration was used to produce this model:

# TIES merge configuration for 4 specialized Qwen fine-tunes
# Goal:
# - Preserve strong domain expertise from each model
# - Reduce destructive interference between skills
# - Keep general reasoning stability from the base model
#
# Recommended for:
# - Qwen2 / Qwen2.5 instruction-tuned variants
# - Same architecture + same parameter count
# - Same tokenizer + same base checkpoint lineage

models:
  # ---------------------------
  # Math specialist
  # ---------------------------
  - model: cs-552-2026-claude-bots/math_model
    parameters:
      # High density because math capabilities are usually sparse
      # and easily lost during merging
      density:
        - filter: self_attn
          value: 0.72
        - filter: mlp
          value: 0.82

      # Strong contribution in reasoning-heavy blocks
      weight:
        - filter: self_attn

  # Knowledge / factual model
  # ---------------------------
  - model: cs-552-2026-claude-bots/general_knowledge_model
    parameters:
      # Moderate density:
      # factual tuning tends to be more distributed
      density: 0.58

      # Slightly lower than math to avoid overwriting reasoning
      weight:
        - filter: self_attn
          value: 1.00

  # ---------------------------
  # Multilingual specialist
  # ---------------------------
  - model: cs-552-2026-claude-bots/multilingual_model
    parameters:
      # Language capabilities are often spread broadly,
      # so use reasonably high density
      density:
        - filter: embed_tokens
          value: 0.90
        - filter: self_attn
          value: 0.68

    parameters:
      # Lower density prevents excessive refusals
