Model Overview

The violetxi/qwen35-9b-harvey-v4-notes-conditioned-100m is a 9 billion parameter model built upon the Qwen/Qwen3.5-9B architecture. This specific checkpoint, checkpoint-6134, is the result of an experiment involving 100 million notes and note-conditioned trajectories, trained over two epochs. The training dataset comprised approximately 70 million note labels and 30 million assistant labels from these trajectories, with a total of nearly 200 million tokens exposed after causal shifting.

Key Characteristics & Training

  • Base Model: Qwen3.5-9B.
  • Training Data: Approximately 100 million supervised tokens, split 70% for note labels and 30% for assistant labels from note-conditioned trajectories.
  • Training Objective: Notes use causal next-token prediction, while trajectory loss is applied to assistant labels.
  • Context Length: Utilizes a packed sequence length of 16,384 tokens during training.

Evaluation & Performance

This model was evaluated on historical thinking-enabled agent generations, regraded with gpt-5.6-sol using the Harvey per-criterion rubric. The metric measures the fraction of attempts passing every criterion across 250 tasks with 4 samples each.

Use Cases

This model is particularly suited for applications requiring:

  • Agentic Workflows: Especially those involving multi-turn interactions and historical thinking.
  • Note-Conditioned Generation: Scenarios where conditioning on specific notes or trajectories is beneficial.
  • Research into Agent Behavior: For exploring and developing agents that can leverage structured 'notes' for improved performance.
