Important Facts

  • Available with 1.5 or 14 billion parameters (14 probably too much, 1.5 should run on anything)
  • Trained with focus on coding
  • Results looking not that promising compared to f.e. qwen2.5-coder but its fast
  • MIT License

DeepCoder is a code reasoning model developed through a collaboration between Agentica and Together AI. It is finetuned from DeepSeek-R1-Distilled-Qwen-14B using distributed reinforcement learning (RL) methods, and is released as a preview model for evaluation and research purposes.


🔍 Overview

DeepCoder is based on a 14-billion parameter architecture and focuses on improving code understanding and reasoning tasks. It reaches 60.6% Pass@1 accuracy on LiveCodeBench, an 8% gain over its base model performance.
Its results are comparable to models like o3-mini-2025-01-031 (Low) and o1-2024-12-17, despite having fewer parameters.


🔧 Key Features

  • Code Reasoning Improvements:
    Designed to handle multi-step programming tasks, algorithmic challenges, and more complex code generation cases.

  • LiveCodeBench Performance:
    Achieves 60.6% Pass@1 on LiveCodeBench, a notable improvement over baseline 14B models.

  • Finetuning Strategy:
    Built on DeepSeek-R1-Distilled-Qwen-14B and finetuned via distributed RL, focusing on better alignment with coding tasks.

  • Resource Considerations:
    With 14 billion parameters, the model targets a middle ground — aiming to deliver higher reasoning ability without the higher resource demands of 30B+ models.

  • Preview Status:
    Currently released as a preview, with potential for further refinements based on broader testing and feedback.


🧠 Architecture

DeepCoder uses a standard transformer-based architecture, initially optimized via distillation and later refined using reinforcement learning techniques.
The focus during training was on improving code reasoning chains rather than purely enhancing token prediction accuracy.
