Walkthrough

The changes involve updates to multiple files in the project, focusing on enhancing the model configuration and initialization processes. Key modifications include the introduction of a new enumeration for model sizes, refactoring of the TextGenerator class to streamline model loading, and significant alterations to the GPTModel class to support size-based configuration. Additionally, updates to dependency management and .gitignore entries were made to improve project organization and maintainability.

Changes

File	Change Summary
`.gitignore`	Updated to ignore PyTorch model files and directories (`.pt`, `models/`).
`pyproject.toml`	Added a comma after the last dependency entry for proper formatting.
`toyllm/model/config.py`	Introduced `GPTModelSize` enum and updated `GPTModelConfig` with a new `name` attribute. Renamed and added model configurations.
`toyllm/model/generate.py`	Refactored `TextGenerator` to simplify initialization by accepting a `gpt_model` parameter.
`toyllm/model/gpt.py`	Modified `GPTModel` to accept `model_size` parameter and added methods for saving/loading model state.
`toyllm/model/train.py`	Updated to use `GPTModelSize` for model instantiation and configuration, reflecting changes in model management.

Poem

🐇 In the garden of code, changes bloom bright,
With models and sizes, a new guiding light.
Text flows like rivers, smooth and so clear,
As rabbits rejoice, for the updates are here!
Hops of delight in the code's gentle dance,
Celebrate progress, give change a chance! 🌼

🪧 Tips

### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit , please review it.` - `Generate unit testing code for this file.` - `Open a follow-up GitHub issue for this discussion.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit testing code for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.` - `@coderabbitai read src/utils.ts and generate unit testing code.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` - `@coderabbitai help me debug CodeRabbit configuration file.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (Invoked using PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. ### Other keywords and placeholders - Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. - Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description. - Add `@coderabbitai` anywhere in the PR title to generate the title automatically. ### CodeRabbit Configuration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](http://discord.gg/coderabbit) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
