vanilj / tess-v2.5-qwen2-72b

我们创建了 Tess-v2.5，这是 Tesoro 系列大型语言模型 (LLM) 中的最新最先进模型。Tesoro 是意大利语中的“宝藏”，是 Migel Tissera 创建的旗舰 LLM 系列。Tess-v2.5 在推理能力、编码能力和数学方面带来了显著的改进。目前，在 MMLU（大量多任务语言理解）评估中，它是排名第一的开源权重模型。它在 Qwen2-72B-Instruct、Llama3-70B-Instruct、Mixtral-8x22B-Instruct 和 DBRX-Instruct 等其他所有开源权重模型上都得分更高。此外，在 MMLU 评估中，Tess-v2.5 (Qwen2-72B) 模型甚至优于前沿的闭源模型 Gemini-1.0-Ultra、Gemini-1.5-Pro、Mistral-Large 和 Claude-3-Sonnet。

Tess-v2.5 (Qwen2-72B) 是在新发布的 Qwen2-72B 基础上微调的，使用了包含 30 万个样本的 Tess-v2.5 数据集，这些样本涉及包括商业和管理、市场营销、历史、社会科学、艺术、STEM 学科和计算机编程在内的多个主题。该数据集使用 Sensei 框架和多个前沿模型（如 GPT-4-Turbo、Claude-Opus 和 Mistral-Large）合成生成。

此模型的计算得到了 KindoAI 的慷慨赞助。

在 AGIEval（Nous）子集上的评估中，此模型与首席之父 GPT-4-0314 模型相比也表现非常出色。

训练过程

通过使用Qwen2-72B的基础权重启动Tess-v2.5模型，随后使用Tess-v2.5数据集进行微调，其中Axolotl作为训练框架。大多数Tess模型遵循一个常见的微调方法：低学习率、低迭代次数和采用极高质量和多样化的数据。该模型在微软Azure的4xA100 VM上进行了4天的训练。该模型尚未与RLHF或DPO对齐。

作者认为，模型的能力似乎主要来自于预训练过程。这是Tess模型每次微调的基础，作者认为保持基础模型的熵非常重要。

# Tess-v2.5 (Qwen2-72B)

![Tess-v2.5](https://hugging-face.cn/migtissera/Tess-v2.5-Qwen2-72B/resolve/main/Tess-v2.5.png)

We've created Tess-v2.5, the latest state-of-the-art model in the Tess series of Large Language Models (LLMs). Tess, short for Tesoro (<em>Treasure</em> in Italian), is the flagship LLM series created by Migel Tissera. Tess-v2.5 brings significant improvements in reasoning capabilities, coding capabilities and mathematics. It is currently the #1 ranked open weight model when evaluated on MMLU (Massive Multitask Language Understanding). It scores higher than all other open weight models including Qwen2-72B-Instruct, Llama3-70B-Instruct, Mixtral-8x22B-Instruct and DBRX-Instruct. Further, when evaluated on MMLU, Tess-v2.5 (Qwen2-72B) model outperforms even the frontier closed models Gemini-1.0-Ultra, Gemini-1.5-Pro, Mistral-Large and Claude-3-Sonnet.

Tess-v2.5 (Qwen2-72B) was fine-tuned over the newly released Qwen2-72B base, using the Tess-v2.5 dataset that contain 300K samples spanning multiple topics, including business and management, marketing, history, social sciences, arts, STEM subjects and computer programming. This dataset was synthetically generated using the [Sensei](https://github.com/migtissera/Sensei) framework, using multiple frontier models such as GPT-4-Turbo, Claude-Opus and Mistral-Large.

The compute for this model was generously sponsored by [KindoAI](https://kindo.ai).

When evaluated on a subset of AGIEval (Nous), this model compares very well with the godfather GPT-4-0314 model as well.

# Training Process

Tess-v2.5 model was initiated with the base weights of Qwen2-72B. It was then fine-tuned with the Tess-v2.5 dataset, using Axolotl as the training framework. Most of Tess models follow a common fine-tuning methodology: low learning rates, low number of epochs, and uses very high quality and diverse data. This model was fine-tuned on a 4xA100 VM on Microsoft Azure for 4 days. The model has not been aligned with RLHF or DPO.

The author believes that model's capabilities seem to come primariliy from the pre-training process. This is the foundation for every fine-tune of Tess models, and preserving the entropy of the base models is of paramount to the author.

# Evaluation Results

Tess-v2.5 model is an overall well balanced model. All evals pertaining to this model can be accessed in the [Evals](https://hugging-face.cn/migtissera/Tess-v2.5-Qwen2-72B/tree/main/Evals) folder.
