Meta is raising the bar in the world of artificial intelligence by introducing its latest version of Llama, an open source language model. latest version, Llama 2, a major upgrade, offering users a comprehensive toolkit to spur innovation and push the boundaries of their digital creativity. Let’s dive into the great features of Llama 2 and explore how to tune this modern model.

Open source AI

have been pre-trained using a wide range of publicly available online resources, Llama 2 He is distinguished by his amazing dexterity and enhanced abilities. Llama -2 chat, the exact model, is the product of integrating publicly available educational data and over 1 million human annotations. This careful approach has ensured that Llama 2 models have a context length twice as long as Llama 1, with an impressive training base of 2 trillion tokens.

Llama 2’s ability to outperform others Open source language models On many external benchmarks, including coding, reasoning, aptitude and knowledge tests, it is a testament to its high level performance.

Training the Llama-2-chat model is a complex process, supported by the incorporation of several technological strategies. At first, Llama 2 uses publicly available online data for pre-training, followed by supervised fine-tuning to create an initial version of Llama-2-chat. The model is then subjected to iterative refinement through reinforcement learning from human feedback (RLHF), using techniques such as rejection sampling and proximal policy optimization (PPO).

When you download the Llama 2 Template, your package will include the following: Template Code, Template Weights, Reading (User’s Guide), Responsible Use Guide, License, Acceptable Use Policy, and Template Card.

One of the main attractions of the Llama 2 is its fine-tuning ability. A comprehensive tutorial is available, instructing users on how to fine-tune the Llama 2 model using quantum low-order approximation (QLoRA) and then upload the model to the Hugging Face model hub.

For example, the tutorial embedded below demonstrates this process using a French dataset, thus enabling the Llama 2 model to generate French text. This involves tuning the model using French quotes, a process inspired by the Hugging Face tutorial, which reduces model accuracy and memory requirements through QLoRA.

In this example tutorial, fine-tuning of the Llama 2 model requires the use of Google Colab, a useful tool that allows less than 15 GB of memory to be used due to the quantum model. It also includes the use of four core libraries: Accelerate, PiFT, Transformers, and Datasets. In addition, weights and biases are used for 4-bit quantization and monitoring of the training process.

The dataset, available on the hub of the Hugging Face model, contains prompts and responses formatted for training the model. During the training process, it is necessary to monitor convergence, and expect that the training loss will decrease over time. Upon completion of the training, the model can be saved and used for text generation. In the video above, also learn how to authenticate your notebook using the Hugging Face form hub and upload the form for future use.

Fine tuning of the Llama 2 expands its capabilities, enabling it to handle a variety of tasks more effectively. It empowers individuals, creators, researchers, and companies to responsibly experiment, innovate, and scale their ideas. Whether you are a beginner or a seasoned professional in the field, taking the time to learn how to tune Llama 2 will surely enhance your AI applications and bring your ideas to life.
