Enter your own API key to use APIs from OpenAI, Anthropic, Azure OpenAI, OpenRouter, or 3rd party services that offers OpenAI API compatibility, such as Ollama and OxyAPI. Using API avoids leaking your code to OpenAI or Anthropic training data.
Compare the code output of different LLM models (for example, GPT-4o & Claude 3.5 Sonnet) side-by-side to see which one is the best for your use case.
Craft and save your best prompts as task instructions or custom instructions to use across different tech stacks like Next.js, Python and SQL.
Fine-tune your prompt with various optimization settings to get the best results.
Organize your source code context using workspaces to manage multiple repositories and projects in one place and switch between them easily, for example, a landing page, a blog, and a web app.
You can also include multiple repositories in a single workspace to work on related projects, for example, a frontend and backend repository that are part of the same project.

Got a curd problems that cursor just can’t get around it. Tried 16x with opus and it finished in one go.

Although my prompt engineer is pretty similar but yours reduces the copy paste hassle as i can just drag and drop the file.

Use ChatGPT Classic instead of the default ChatGPT. ChatGPT Classic is better than ChatGPT for coding tasks. The Claude 3.5 Sonnet is a better model than GPT-4o for coding tasks.
ChatGPT Classic provides better responses as it has less noise in system prompt, leading to the model following instructions more closely, and give you more free context token to fit more input. It uses GPT-4 behind the scene and provides better results overall.
According to paul-gauthier, Claude 3.5 Sonnet beats GPT-4o on Aider's code editing benchmark.
