mira-1-xl

mira-1-xl is a multimodal (vision + text) 27B-class model merge built on Qwen3.5-27B, blended with Claude-Opus-style reasoning distills and a Fable-style creative distill.

This repo is intended as a premium “daily driver”:

  • strong instruction following
  • improved reasoning / “thinking” behavior vs base
  • better creative tone + narrative output
  • keeps Qwen3.5’s vision capability (image+text conversations)

Not affiliated with Alibaba/Qwen, TeichAI, Jackrong, or Anthropic/Claude. “Claude / Opus / Fable” are referenced only to describe the upstream community models used as merge sources.


What’s inside

  • Architecture: Qwen3.5 multimodal (Qwen3_5ForConditionalGeneration)
  • Precision: BF16 weights
  • Modalities: image + text → text

Merge recipe (DARE-TIES)

This model is a 3-way DARE-TIES merge (drop + rescale, then weighted delta sum), with per-source sparsity (“density”) and weights.

Important: DARE-style merges are stochastic unless you fix RNG seeds. Your merge may differ slightly if you re-run.

Base

  • Qwen/Qwen3.5-27B

Merge sources + parameters

Source model Role / flavor density weight
Jackrong/Qwen3.5-27B-Claude-4.6-Opus-Reasoning-Distilled reasoning + structured solutions 0.70 0.40
TeichAI/Qwen3.5-27B-Claude-Opus-4.6-Distill instruction following + general ability 0.65 0.35
TeichAI/Qwen3.8-27B-Fable-Distill creative writing / planning style 0.60 0.30

Normalization: enabled (per-tensor norm stabilization)
Output dtype: bf16


Intended use

Great for:

  • multimodal Q&A (“what’s in this image?”, “summarize this screenshot”, etc.)
  • long-form writing (stories, scripts, outlines)
  • agent-style planning (multi-step task decomposition)
  • general chat + instruction following
  • “reasoning-ish” tasks where base Qwen can be too shallow

Not ideal for:

  • safety-critical domains (medical/legal/financial advice) without human review
  • guaranteed factuality (hallucinations still happen)
  • strict reproducibility (DARE merges are not deterministic unless seeded)

Usage (Transformers)

1) Quick pipeline (image-text-to-text)

from transformers import pipeline

pipe = pipeline("image-text-to-text", model="Bc-AI/mira-1-xl")  # <- change to your repo id

messages = [
  {
    "role": "user",
    "content": [
      {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
      {"type": "text", "text": "What animal is on the candy? Answer in one sentence."}
    ]
  }
]

out = pipe(text=messages, max_new_tokens=128)
print(out)
