Model Overview

Kimi-K2T-ling-coder-sft-sandboxes-1-maxeps-32k is an 8 billion parameter language model developed by laion. It is a fine-tuned variant of the Qwen/Qwen3-8B base model, specifically adapted using the open-athena/Kimi-K2T-ling-coder-sft-sandboxes-1-maxeps-32k dataset. This specialization implies a focus on code-related tasks, likely within simulated or sandbox development environments.

Training Details

The model was trained with a learning rate of 4e-05 over 7.0 epochs. Key training hyperparameters include a train_batch_size of 1, gradient_accumulation_steps of 2, leading to a total_train_batch_size of 16. The optimizer used was ADAMW_TORCH_FUSED with specific beta values and epsilon, and a cosine learning rate scheduler with a warmup ratio of 0.1. The training utilized a multi-GPU setup with 8 devices.

Technical Stack

The training environment leveraged:

  • Transformers version 4.57.3
  • Pytorch version 2.9.0+cu128
  • Datasets version 4.4.1
  • Tokenizers version 0.22.2

Potential Use Cases

Given its fine-tuning on a coder-specific dataset, this model is likely suitable for:

  • Code generation and completion within sandbox environments.
  • Code understanding and analysis for specific programming contexts.
  • Assisting developers with coding tasks that benefit from a large context window (32768 tokens).
