# PR #435: Workflow Design Impact Analysis

## Affected Workflows

None.

The PR titled "Update README.md" only modifies the `README.md` file by enhancing its content with additional sections for better user guidance, such as model specifications, requirements, quick start instructions, example usage, hardware guidance, troubleshooting, and contributing guidelines. It also refines the downloading weights section and license information.

This documentation update does not impact the code files relevant to any workflows defined in `.exp/workflows.json`:

- Grok-1 Inference and Sampling (relevant: run.py, runners.py, model.py, checkpoint.py, tokenizer.model)
- Model Loading and Initialization (relevant: model.py, runners.py, checkpoint.py)
- Model Forward Pass and Logits Computation (relevant: runners.py, model.py)

No changes to model code, runners, or checkpoint handling that would affect these workflows' designs or implementations.

## Summary of PR Changes

Key updates to README.md include:

- **Introduction**: Clarified the purpose and setup process.
- **Model Specifications**: Detailed parameters, architecture (314B MoE with 8 experts, 2 per token), layers, heads, embedding size, tokenizer, features like RoPE, sharding, quantization, and context length.
- **Requirements**: Listed Python version, GPU needs, JAX, SentencePiece, optional huggingface_hub.
- **Quick Start**: Step-by-step installation and running instructions.
- **Checkpoint Layout**: Explained directory structure.
- **Tokenization**: Described SentencePiece usage.
- **Example Usage**: Basic and advanced command-line examples for prompts, sampling params.
- **Hardware Guidance**: Tips on GPUs, multi-GPU, memory management.
- **Performance Notes**: Noted implementation priorities and optimizations.
- **Troubleshooting**: Common issues and solutions.
- **Contributing**: Guidelines for forking, changes, PRs.
- **Downloading the Weights**: Updated HF Hub instructions.
- **License**: Minor rephrasing.

These improvements enhance accessibility and usability without altering functionality or workflow designs.

No design documents in `.exp/` require updates, as there are no changes to workflow implementations or diagrams.
