Model Details

Model Description

This model is a fine - tuned version of Qwen3 - 1.7B, enhanced using 1 - shot Reinforcement Learning with Verifiable Reward (RLVR) to improve mathematical reasoning capabilities, as described in Wang et al. (2025). The RLVR method uses a single training example to boost performance on mathematical benchmarks. The model has been evaluated in frameworks like ARIES (Gimenes et al., 2025), a multi - agent architecture for topological reasoning, demonstrating strong performance in tasks such as coding and mathematical problem - solving. Note that the RLVR paper primarily discusses Qwen2.5 - Math - 1.5B; performance metrics for Qwen3 - 1.7B are inferred and may vary. This model card was updated on June 11, 2025.

Uses

Direct Use

The model is designed for zero - shot classification and reasoning tasks, particularly in mathematical problem - solving and coding. It can be used directly for tasks like solving problems from the MATH500 benchmark, HumanEval coding tasks, or simpler topological reasoning tasks (e.g., list sorting, set intersection) without additional fine - tuning.

Downstream Use

The model can be integrated into larger systems for:

• Automated code generation and verification (e.g., HumanEval tasks).
• Educational tools for mathematical problem - solving.
• Multi - agent reasoning frameworks like ARIES, where it can act as a policy or reasoning agent in thought graph environments.
• Further fine - tuning for domain - specific reasoning tasks.

Out - of - Scope Use

• The model is not optimized for non - English tasks or multimodal inputs.
• It may perform poorly on tasks requiring long - horizon planning or highly domain - specific knowledge without further fine - tuning.
• Misuse in generating biased or harmful content is out of scope, as the model inherits biases from the base LLM.

Bias, Risks, and Limitations

Bias and Risks

• Inherent LLM Biases: The model may propagate biases present in the base Qwen3 - 1.7B model, potentially leading to unfair or misleading outcomes in reasoning tasks.
• Stochastic Errors: As noted in Gimenes et al. (2025), the stochastic nature of LLM outputs can result in incorrect reasoning paths, especially in deep decomposition settings.
• Environmental Impact: Inference - heavy approaches like RLVR and ARIES require significant computational resources, raising sustainability concerns (Gimenes et al., 2025).
• Label Noise Robustness: RLVR is partially robust to label noise, but performance degrades with high error rates (e.g., 90% wrong labels), as shown in Wang et al. (2025).

Limitations

• Model Size: Smaller models (e.g., 1.7B parameters) may underperform compared to larger models like Llama - 3.1 - 405B in complex reasoning tasks (Gimenes et al., 2025).
• Decomposition Depth: Performance deteriorates with increased problem decomposition depth, particularly in tasks with low aggregation success probabilities (Gimenes et al., 2025).
• Overfitting in 1 - shot RLVR: Prolonged training on a single example can lead to incomprehensible outputs for the training example, though test performance remains robust (Wang et al., 2025).
• Generalization: Evaluation is limited to specific benchmarks (MATH500, HumanEval, sorting, set intersection), and results may not generalize to ambiguous or multi - modal tasks.
• Model Uncertainty: Limited information on Qwen3 - 1.7B’s base performance; results are extrapolated from Qwen2.5 - Math - 1.5B.

Recommendations

⚠️ Important Note

Users should validate outputs for critical applications due to potential stochastic errors.

💡 Usage Tip

• Consider environmental impact when deploying at scale; optimize query efficiency where possible.
• For complex tasks, consider using larger models or ensemble approaches as in ARIES.
• Monitor for biases and ensure fairness in downstream applications.

Training Details

Training Data

• RLVR Training Data: A single example (e.g., $\pi_1$: solving a physics - related math problem involving cube root calculation) from the DeepScaleR subset (DSR - sub) or similar datasets, as described in Wang et al. (2025). The dataset used is HuggingFaceH4/MATH - 500.
• ARIES Evaluation Data: HumanEval for coding, and custom benchmarks for list sorting and set intersection tasks (Gimenes et al., 2025).

Training Procedure

Preprocessing

• For RLVR, the training example is formatted as a prompt with a ground truth label, encouraging step - by - step reasoning (Chain - of - Thought, CoT).
• In ARIES, thought graph states are represented textually, including node descriptions, edges, and action history.

Training Hyperparameters

• RL Algorithm: GRPO (default) or PPO, with policy gradient loss and entropy loss to promote exploration (Wang et al., 2025).
• Entropy Loss Coefficient: Tuned to enhance performance, critical for post - saturation generalization.
• Training Steps: Approximately 1.4k steps before overfitting in 1 - shot RLVR.
• Training Regime: Not specified; likely fp16 mixed precision based on standard LLM practices.
• Temperature: 1.0 for sampling in ARIES experiments (Gimenes et al., 2025).

Speeds, Sizes, Times

• RLVR Training: Conducted on unspecified hardware; assumed to be GPU - based given the model size.
• ARIES Experiments: Llama - 3.1 - 70B used 8×A6000 GPUs, Llama - 3.1 - 405B used 16×H100 GPUs, totaling ~3k GPU hours (Gimenes et al., 2025).

Evaluation

Testing Data, Factors & Metrics

Testing Data

• MATH500: 500 mathematical reasoning problems (Wang et al., 2025).
• Other Math Benchmarks: AIME24, AMC23, Minerva Math, OlympiadBench, AIME25 (Wang et al., 2025).
• HumanEval: Python coding problems with test cases (Gimenes et al., 2025).
• Sorting and Set Intersection: Custom benchmarks at varying difficulty levels (32, 64, 128 elements) (Gimenes et al., 2025).

Factors

• Model Size: Evaluated with 1.7B (assumed), 7B, and 405B parameter models.
• Decomposition Depth: Impacts performance in topological reasoning tasks.
• Training Example: Specific examples (e.g., $\pi_1$, $\pi_{13}$) yield varying improvements.
• RL Algorithm: GRPO vs. PPO.
• Ensemble Size: Policy agent ensemble size (1–15) in ARIES.

Metrics

• Accuracy: Percentage of correct solutions (HumanEval, MATH500).
• Error Function ($\mathcal{E}$): Task - specific error for sorting and set intersection, defined as incorrect pairs or missing/extra elements (Gimenes et al., 2025).
• Query Cost: Number of LLM queries for search ($C_s$) and inference ($C_i$).
• Average Performance: Mean accuracy across multiple benchmarks.

Results

• RLVR Results (Wang et al., 2025):

  • Assumed performance for Qwen3 - 1.7B based on Qwen2.5 - Math - 1.5B: improved from 36.0% to 73.6% on MATH500 and 17.6% to 35.7% on average across six benchmarks with 1 - shot RLVR using example $\pi_1$.
  • 2 - shot RLVR slightly outperformed full - set RLVR (74.8% on MATH500, 36.6% average).
  • Cross - domain generalization observed (e.g., geometry example improving algebra tasks).
  • Robust to 60% label noise, but performance drops at 90% noise.

• ARIES Results (Gimenes et al., 2025):

  • Achieved 89.0% accuracy on HumanEval with Llama - 3.1 - 405B, 28.9% higher than the best static schedule baseline (GoT_{100%}). Qwen3 - 1.7B performance assumed to be comparable but less robust.
  • Reduced inference cost by 54% compared to optimized static schedules.
  • 2.3× error reduction on set - intersection32 with 116× lower query cost.
  • Failure modes: smaller models (e.g., 1.7B) and high decomposition depth reduce performance.

Summary

The model likely excels in mathematical and coding tasks with minimal training data, leveraging RLVR for efficient reasoning enhancement and ARIES for dynamic topological reasoning. However, performance is constrained by model size and task complexity, with uncertainty due to limited Qwen3 - 1.7B - specific data.

Model Examination

• Post - Saturation Generalization (Wang et al., 2025): Test accuracy improves even after training accuracy saturates, driven by non - zero policy gradient loss and entropy loss.
• Self - Reflection (Wang et al., 2025): Increased frequency of self - reflective terms in outputs during RLVR training.
• Transition Probabilities (Gimenes et al., 2025): Refinement ($\phi_{\text{ref}}$) has low success probability (e.g., 0.29 for HumanEval), impacting exploration strategies.
