Training Llama 2

The training process for Llama 2 involves three core steps: pre-training, fine-tuning to make it a chat model, and a human feedback loop to produce different reward models for helpfulness and harmlessness. The team found that high-quality data set annotation was crucial for achieving high-quality supervised fine-tuning examples. They also used rejection sampling and proximal policy optimization techniques for reinforcement learning with human feedback. This iterative improvement process showed a linear improvement in both safety and helpfulness metrics, indicating that it’s possible to improve both aspects simultaneously.

The team behind Llama 2 also conducted both automatic and human evaluations, with around 4,000 different prompts evaluated for helpfulness and 2,000 for harmlessness. However, they acknowledged that human evaluation can be subjective, especially when there are many possible valuable responses to a prompt. They also highlighted that the distribution of prompts used for evaluation can heavily affect the quality of the evaluation, as people care about a wide variety of topics.

AI models

Llama 2 has been introduced as a competitive model that performs significantly better than open-source models like Falcon or Llama 1, and is quite competitive with models like GPT 3.5 or Palm. The team also discussed the concept of “temporal perception”, where the model is given a cut-off date for its knowledge and is then asked questions about events after that date. This feature allows the model to provide more accurate and contextually relevant responses.

Despite the advancements made with Llama 2, the team acknowledges that there are still many open questions to be resolved in the field. These include issues around the hallucination behavior of models, the need for models to be more factual and precise, and questions about scalability and the types of data used. They also discussed the use of Llama 2 as a judge in evaluating the performance of other models, and the challenges of using the model to evaluate itself.

Fine tuning

The team also mentioned that they have not released their supervised fine-tuning dataset, and that the model’s access to APIs is simulated rather than real. They noted that the model’s tool usage is not particularly robust and that more work needs to be done in this area. However, they also discussed the potential use of language models as writing assistants, suggesting that the fine-tuning strategy and data domain should be adjusted depending on the intended use of the model.

Llama 2 represents a significant step forward in the development of large language models. Its improved capabilities, coupled with the team’s commitment to open-source tooling and community feedback, make it a promising tool for a variety of applications. However, as with any technology, it is important to continue refining and improving the model, addressing the challenges and open questions that remain. The future of large language models like Llama 2 is bright, and it will be exciting to see how they continue to evolve and shape the field of artificial intelligence.
