ARIES-RLVR: Advanced Reasoning Model
A Qwen3-4B model enhanced with Tree-of-Thoughts (ToT) reasoning and RLVR-inspired training techniques for improved multi-step problem solving.
🎯 Overview
This model extends the base Qwen3-4B with advanced reasoning capabilities through a custom training pipeline that combines tree-based exploration with reward-guided learning. The goal is to improve performance on complex reasoning tasks that require multi-step thinking and logical deduction.
🧠 Training Methodology
Core Components
1. Tree-of-Thoughts (ToT) Generation
- Multi-branch exploration of reasoning paths
- Adaptive depth based on problem complexity
- Parallel evaluation of alternative solutions
- Best-path selection using learned heuristics
2. Multi-Agent Policy System
Four specialized reasoning agents work in parallel:
- Conservative Agent: Focuses on proven, reliable reasoning patterns
- Exploratory Agent: Seeks novel solution approaches
- Balanced Agent: Optimizes between exploration and exploitation
- Reflective Agent: Validates and self-corrects reasoning chains
3. Adaptive Complexity Scaling
- Automatically adjusts search depth (1-3 levels) based on problem difficulty
- Dynamic branching factor (2-5 branches)
- Early stopping when high-confidence solutions are found
- Resource allocation proportional to problem complexity
4. Hybrid Reward System
Multi-objective reward function combining:
- Correctness: Answer accuracy
- Format Quality: Proper structure and presentation
- Semantic Coherence: Logical consistency in reasoning steps
Training Process
- Problem Analysis: Difficulty assessment and strategy selection
- ToT Exploration: Multi-path reasoning with adaptive depth
- Path Evaluation: Quality scoring of reasoning chains
- Supervised Fine-Tuning: Training on high-quality reasoning examples
- Reward Optimization: RLVR-style reinforcement of effective patterns
📊 Training Data
Trained on diverse reasoning tasks from multiple domains:
- HuggingFaceH4/MATH-500: Mathematical problem solving
- openbmb/RLPR-Train-Dataset: Reward-based reasoning patterns
- ai2lumos/lumos_multimodal_ground_iterative: Multi-step reasoning
- SAGI-1/reasoningData_200k: General reasoning tasks
Data selection emphasizes:
- High variance in difficulty
- Multiple reasoning types (math, logic, pattern recognition)
- Problems requiring multi-step solutions
🚀 Usage
Basic Generation
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
model = AutoModelForCausalLM.from_pretrained(
"ziadrone/airesupdated-v3",
torch_dtype=torch.bfloat16,
device_map="auto",
trust_remote_code=True
)
tokenizer = AutoTokenizer.from_pretrained(
"ziadrone/airesupdated-v3",
trust_remote_code=True
)
prompt = "Solve step by step: If 5 machines take 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(
**inputs,
max_new_tokens=256,
temperature=0.7,
do_sample=True,
top_p=0.9
)
result = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(result)
Recommended Settings
