I just sent out my August 2025 sponsors-only newsletter summarizing the past month in LLMs and my other work. Topics included GPT-5, gpt-oss, image editing models (Qwen-Image-Edit and Gemini Nano Banana), other significant model releases and the tools I'm using at the moment.

If you'd like a preview of the newsletter, here's the July 2025 edition I sent out a month ago.

New sponsors get access to the full archive. If you start sponsoring for $10/month or more right now you'll get instant access to the August edition in my simonw-private/monthly GitHub repository.

If you've already read all 85 posts I wrote in August the newsletter acts mainly as a recap, but I've had positive feedback from people who prefer to get the monthly edited highlights over reading the firehose that is my blog!

Here's the table of contents for the August newsletter:

  • GPT-5
  • OpenAl's open models: gpt-oss-120b and gpt-oss-20b
  • Other significant model releases in August
  • Image editing: Qwen-Image-Edit and Gemini Nano Banana
  • More prompt injection and more lethal trifecta
  • Tools I'm using at the moment
  • Bonus links
