First impressions continue to improve with Stepfun Flash 3.7. I built another Northwind full CRUD database example app, similar to what I've built with Deepseek-4-pro, Qwen 3.6, and other favorite models. It only took 2 prompts to complete, and would likely have been only 1 prompt if I'd asked for full CRUD functionality in the initial query:

Along the way, it provided a link to a web site containing the Northwind database as a downloadable SQLite file, and built the code of the app to work with this file:
https://github.com/jpwhite3/northwind-SQLite3
Results worked perfectly first shot.
Then I had the agent build a zip file package with everything needed to install the app on another server, and it yielded the file linked above, which included detailed install instructions.
I also had it build a 3D space invaders game. This was the first-shot result - bullets don't work yet, but a decent initial output:

Additionally, I asked the model set up Rustdesk to be restarted every time the computer restarts, and it did a perfect job first shot.
So far, step-3.7-flash feels more similar to a frontier model than most of the other models I've self hosted. I do wish it was just a bit smaller at q4 compression, because there's not a ton of room for KV cache (I had it set up to use ~89k).
I don't think it will dethrone Qwen 3.6 for basic coding tasks yet, but it's another great tool - the best yet for knowledge, which still runs at a fast speed.
