What's New

Andrej Karpathy is one of the leading AI researcher in the world and currently working at OpenAI. He tweets, his use of Cursor IDE with Sonnet 3.5, makes his coding workflow centers on "half-coding" and natural language prompts.


This shift marks a significant advancement in AI-assisted programming, potentially transforming development workflows.


How to use Cursor with Claude Sonnet 3.5

  • Cursor, available at cursor.com, which offers a premium subscription for $20 monthly. This includes:

  • 500 fast premium requests

  • Unlimited slow premium requests

  • Integration with Sonnet 3.5

Developers write initial code snippets or comments to guide the AI, then use tab completion to generate full code blocks. This method can produce 100-line code diffs in minutes, substantially reducing development time.


What others said about Cursor and Sonnet 3.5

Users report building complex applications, including backend, frontend, search, and filters, in a single day instead of the typical 3-4 days. The AI generates performant code with minimal reliance on external libraries, though it excels more at boilerplate tasks. This will lower the barrier to entry for software development, allowing individuals with minimal coding experience to build competent products.

The system's efficiency stems from its seamless integration of advanced language models into the coding environment.


Limitations

While the tool shows promise, it requires programming knowledge for effective use and error correction. 


Special Note

Andrej Karpathy specifically mentioned in a separate post that he is unaffiliated with anysphere.inc the creators of Cursor in response to some accusations.

How to use Ideogram for generating images

Ideogram 2.0 is the brand new state-of-the-art AI image generator. It's web application allows you to browse and generate images from text. Within the user interface, you can generate images, browse and filter previously generated images, curate your user profile, manage your subscription, and more.


Step-1

Sign up at Ideogram's website. You get free credits to start.


Step-2

Click "Describe what you want to see" and enter your prompt.


Step-3

  • Adjust settings:

  • Choose aspect ratio

  • Select AI model (use 2.0)

  • Pick style (Realistic, Design, 3D, or Anime)

Step-4
Click "Generate" to create four images.


For each image, you can:

  • Pin to profile

  • Like

  • Make public/private

  • Retry generation

  • Remix

  • Upscale (up to 2x)

  • Edit (with subscription)
