Stable Diffusion 2.0 and the Importance of Negative Prompts for Good Results. Stable Diffusion 2.0 is out, and it’s a very different model from 1.4/1.5. It’s trained using a new text encoder (OpenCLIP, in place of OpenAI’s CLIP) which means a lot of the old tricks—notably using “Greg Rutkowski” to get high quality fantasy art—no longer work. What DOES work, incredibly well, is negative prompting—saying things like “cyberpunk forest by Salvador Dali” but negative on “trees, green”. Max Woolf explores negative prompting in depth in this article, including how to combine it with textual inversion. # 29th November 2022, 1:22 am

I Resurrected “Ugly Sonic” with Stable Diffusion Textual Inversion (via) “I trained an Ugly Sonic object concept on 5 image crops from the movie trailer, with 6,000 steps [...] (on a T4 GPU, this took about 1.5 hours and cost about $0.21 on a GCP Spot instance)” # 20th September 2022, 3:35 am

When I was curating my generated tweets, I estimated 30-40% of the tweets were usable comedically, a massive improvement over the 5-10% usability from my GPT-2 tweet generation. However, a 30-40% success rate implies a 60-70% failure rate, which is patently unsuitable for a production application.

Tempering Expectations for GPT-3 and OpenAI’s API. Insightful commentary on GPT-3 (which is producing some ridiculously cool demos at the moment thanks to the invite-only OpenAI API) from Max Woolf. # 18th July 2020, 7:29 pm

A List of Hacker News’s Undocumented Features and Behaviors (via) If you’re interested in community software design this is a neat insight into the many undocumented features of Hacker News, collated by Max Woolf. # 6th June 2020, 5:36 pm

Things About Real-World Data Science Not Discussed In MOOCs and Thought Pieces (via) Really good article, pointing out that carefully optimizing machine learning models is only a small part of the day-to-day work of a data scientist: cleaning up data, building dashboards, shipping models to production, deciding on trade-offs between performance and production and considering the product design and ethical implementations of what you are doing make up a much larger portion of the job. # 11th December 2018, 8:51 pm
