## Scatter Plot: Chain of Thought Accuracy vs. Answer Only Accuracy for Various Tasks
### Overview
The image is a scatter plot comparing the accuracy of "Chain of Thought" (CoT) and "Answer Only" (AO) approaches for different language models (InstructGPT, Codex, and PaLM 540B) across a range of tasks. The x-axis represents the accuracy difference (CoT - AO), and the y-axis lists the tasks. Each data point represents the accuracy difference for a specific model and task.

### Key Observations
* InstructGPT consistently benefits from the Chain of Thought approach across all tasks.
* Codex shows mixed results, with some tasks benefiting from CoT and others not.
* PaLM 540B shows a moderate benefit from CoT, generally less pronounced than InstructGPT.
* The "All Tasks (avg)" data points for each model reflect the general trend observed for the individual tasks.
### Interpretation
The data suggests that the effectiveness of the Chain of Thought approach varies significantly depending on the language model and the specific task. InstructGPT appears to be the most sensitive to the benefits of CoT, while Codex shows more task-dependent performance. PaLM 540B exhibits a more consistent, albeit less dramatic, improvement with CoT.
The vertical lines could represent thresholds or benchmarks for acceptable accuracy differences. The dashed black line at 0 indicates the point where CoT and AO have equal accuracy. The other lines may represent target accuracy improvements or significant performance differences.
The tasks themselves likely vary in complexity and the degree to which they benefit from explicit reasoning steps. Tasks with a higher "λ" symbol may be more amenable to the Chain of Thought approach. Further investigation into the nature of these tasks and the internal mechanisms of each language model would be needed to fully explain the observed differences.
