🔎 Overview

Logics-PPT-Qwen3.6-35B-A3B-SFT is a presentation-generation model built on top of Qwen3.6-35B-A3B, an MoE backbone, for single-page HTML slide generation.

The model is trained for end-to-end presentation generation through a slide-wise HTML generation paradigm within the OpenClaw framework. In our study, Single-HTML is adopted as the final generation setting because it offers stronger robustness and optimization efficiency than multi-page HTML and Python-based generation.

This release corresponds to the SFT stage of our unified training pipeline for presentation intelligence:

1. Cross-validated data synthesis
2. Guided supervised fine-tuning
3. Reinforcement learning with verifiable rewards

This checkpoint is the final pre-RL SFT model for the 35B-A3B MoE backbone.

Why this model?

PPT generation is a long-horizon task that jointly requires:

• document understanding,
• information acquisition,
• content organization,
• layout planning,
• and visually coherent slide construction.

This model is designed to improve presentation generation beyond a generic base model through:

• cross-validated synthetic task and rubric construction
• teacher-enhanced trajectory distillation
• mixed-teacher supervision
• lightweight filtering of low-quality trajectories

The goal of this SFT stage is to substantially improve both:

• benchmark-level presentation quality, and
• basic slide aesthetics before RL refinement.

🧠 Training Recipe

Stage 1: Cross-validated data synthesis

The paper constructs a synthetic PPT-generation training corpus through a five-stage pipeline:

• source profiling
• task construction
• rubric generation
• principle audit
• rubric tightening

Stage 2: Guided SFT with mixed teachers

The model is trained from Qwen3.6-35B-A3B using supervised fine-tuning on distilled presentation-generation trajectories.

Teacher models:

• Qwen-3.8-Max: strong general coding and agentic reasoning
• GLM-5.2: presentation-specialized teacher

Teacher guidance is strengthened through progressively richer prompts:

• Base
• Pro
• Max

Training corpora are combined under:

• Single
• Mixed
• Mixed+Filter

The released model corresponds to the selected mixed+filter checkpoint used as the RL initialization for the MoE backbone.

Selected setting for this release:

• Target backbone: Qwen-3.6-35B-A3B
• Training regime: mixed + filter
• Selected teacher composition: qwen + glm_pro (filter)

📊 Experimental Results

Main SFT results

Reported overall benchmark scores from the paper:

Compared with the base model, this SFT checkpoint improves:

• PresentBench: 64.93 → 74.28 (+9.35)
• GDPVal (PPT subset): 74.01 → 78.17 (+4.16)

These results show that the SFT pipeline produces substantial gains on both the in-domain benchmark and the external PPT evaluation subset.

🎯 Intended Use

This model is intended for research use in:

• automatic presentation generation
• HTML-based slide generation
• multimodal layout generation
• long-horizon agentic generation
• supervised post-training for deck synthesis
• MoE backbones for structured generation

It is especially suitable for research on systems that:

• read source materials,
• plan a multi-slide presentation,
• generate one HTML file per slide,
• and render outputs for downstream evaluation or refinement.

⚠️ Limitations

• This is an SFT checkpoint, not the final RL-refined model.
• Although it significantly improves overall presentation quality, post-render visual issues may still remain, including:
  • excessive whitespace,
  • imperfect balance,
  • element overlap,
  • and other fine-grained layout defects.
• The model is optimized for single-slide HTML generation rather than native .pptx output.
• Real deployment still requires the broader agent and rendering stack used in the paper.
• Performance depends on task prompting, reference-material access, and rendering setup.

🚀 Quickstart

Transformers: text-generation smoke test

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "Logics-MLLM/Logics-PPT-Qwen3.6-35B-A3B-SFT"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    dtype=torch.bfloat16,
    device_map="auto",
)
model.eval()

messages = [{
    "role": "user",
    "content": (
        "Create an 8-slide presentation as separate HTML slides for a technical topic. "
        "Use a consistent design system, clear hierarchy, and readable visual layout."
    ),
}]

inputs = tokenizer.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_dict=True,
    return_tensors="pt",
).to(model.device)

with torch.inference_mode():
    output = model.generate(
        **inputs,
        max_new_tokens=2048,
        do_sample=True,
        temperature=1.0,
        top_p=0.95,
        top_k=20,
    )

completion = output[0, inputs["input_ids"].shape[-1]:]
print(tokenizer.decode(completion, skip_special_tokens=True))

This is only a minimal text-generation smoke test.
Actual presentation generation in our setup additionally uses:

• the OpenClaw-style agent framework,
• task instruction files and reference materials,
• browser rendering
