Great agentic results even with IQ1_S!

I saw some claims that 0731 Deepseek V4 Flash was more affected by quantization.

For fun I wanted to test how well the IQ1_S could do in an agentic workflow, as I can fit it with full GPU offload in 96GB VRAM with 256K context easy.

I gave it a pretty detailed prompt to create a simple Mastadon API local timeline viewer in rust, I chose rust because
1.) It would be a good test that deviates from standard html test prompts
2.) I didn't even have rust installed on my macbook, so having the model figuring that out and getting it set up would be a challenge within itself.

I just let it go to town in Pi coding agent.

Now, it did reason a lot, but the end result was a native compiled MacOS .app file in rust that does exactly what I expected it to do, with a pretty stable 30 t/s generation even at 100k+ context! I'd say that even in the lowest quant, this model is very usable.

@phakio Wowww Amazing! Do you happen to have the same test for something like Qwen 27B Q8? I'm trying to determine if it would be worth trying to fit DeepSeek V4 Flash at Q1 into my setup, or if I should just stick with Qwen 27B Q8 711 by DavidAU.

@je0923 unfortunately I do not, but I am looking forward to testing the new Qwen 3.8 27B next week. I'll probably run the same test with that when it's out!

However I did use this deepseek model yet again for another workflow, this time a TUI application written in rust, that uses multiple API endpoints to parse SoundCloud links and download the songs / convert them to mp3 and properly tag them, and it works flawlessly... it did have to reason a lot though just like before

I'd say if you don't mind waiting (because this model seems to think a lot in order to get its stellar results) give this one a try!
