Reflection Llama-3.1 70B: Testing & Summary of What We Know

Reflection Llama 3.1: A Self-Correcting LLM Released September 6, 2024

Reflection Llama 3.1, a refined version of the Llama 3.1 70B Instruct model, debuted on September 6th, 2024. Its innovative "reflection-tuning" allows for self-error detection and correction, aiming for heightened accuracy. This article explores the model, its functionality, and how to access and test it.

Reflection Llama 3.1: Development and Timeline

The model's launch generated significant buzz, initially boasting superior performance to closed-source models like GPT-4o and Claude 3.5 Sonnet on benchmark tests. However, subsequent testing by Artificial Analysis revealed inconsistencies. An initial upload to Hugging Face contained a weighting error. A corrected version, deployed on OpenRouter, uncovered an unexpected self-identification as Claude Sonnet 3.5, raising questions about its true foundation. While private API testing showed improved performance, independent verification remained impossible. The latest Hugging Face iteration, while accessible via this link [link omitted as per original text], demonstrated performance inferior to the private API version. Reproducibility issues persist, leaving the model's actual capabilities uncertain.

Understanding Reflection Llama 3.1

Reflection Llama 3.1 leverages the Llama 3.1 70B Instruct model and incorporates reflection-tuning. This process involves:

• Thinking tags (<thinking></thinking>): The model details its reasoning process.
• Reflection tags (<reflection></reflection>): The model identifies and corrects errors in its reasoning.
• Output tags (<output></output>): The model presents its final answer.

This structured approach enhances transparency and accuracy. The model was trained using synthetic data from Glaive AI, highlighting the importance of high-quality datasets. Despite being in the research phase, it reportedly outperforms leading closed-source models on benchmarks like MMLU, MATH, and GSM8K. Its creators anticipate the forthcoming Reflection Llama 405B to significantly surpass these models.

Setting Up Reflection Llama 3.1 on Google Colab

Accessing Reflection Llama 3.1 is straightforward with the right tools. It's available on Hugging Face, Ollama, and Hyperbolic Labs. Google Colab Pro, with its A100 GPU (requiring purchased compute units), is recommended for the 70B model.

Step 1: GPU Access

Connect to an A100 GPU via Runtime → Change runtime type.

Step 2: Ollama Installation and Model Download

Use the terminal in Colab (using !pip install colab-xterm and %xterm) to install Ollama (curl -fsSL <https:> | sh</https:>) and run it (ollama serve). In a second terminal, download the Reflection model (ollama run reflection).

Step 3: LangChain Integration

Install LangChain (!pip install langchain langchain_community langchain-openai langchain-ollama) and define the prompt template (using PromptTemplate from langchain.prompts and ChatOllama from langchain_ollama). Initialize the model using ChatOllama(model="reflection", temperature=0) and invoke it with your input. Example:

reflection_model.invoke({'input': "Hi, how are you?"})

Reflection Llama 3.1 in Action

The model was tested with various prompts:

• Numerical reasoning: Successfully calculated and compared returns, though the reflection section showed inconsistencies.
• Simple comparisons: Initially erred in comparing 9.9 and 9.11, but adding "Think carefully" improved accuracy.
• Counting occurrences: Accurately counted the "R"s in "strawberry."
• Ambiguity resolution: Correctly solved the doctor riddle, demonstrating bias recognition.
• False information correction: Initially accepted a false statement about the Eiffel Tower's location but self-corrected.
• Commonsense reasoning: Successfully reasoned through a cause-and-effect scenario, acknowledging multiple possibilities.
• Code generation: Generated functional code for a simple Snake game.

Reflection Llama 3.1: Applications and Limitations

Reflection Llama 3.1's self-correction makes it suitable for math, logic, code generation, debugging, and fact-checking. However, its self-correction adds complexity, potentially impacting speed and cost. Inaccuracies may still occur. The upcoming Reflection Llama 405B promises significant improvements.

Conclusion

Reflection Llama 3.1's reflection-tuning is a promising development, but reproducibility issues highlight the ongoing challenges in AI model development. While the self-correction is valuable, rigorous testing and validation remain crucial.
