Hilarious sentence: "DeepSeek-V4.1-Flash-1017 is a minor update to DeepSeek-V4.1-Flash, delivering substantial improvements across reasoning, coding, agentic tasks, and visual benchmarks." (emphasis mine)

It passed my threshold for not caring to try new models back with DS4, I use it for literally everything. Announcements of new models in the series always feel curious, because it doesn't really feel like there's much left to fix that would improve on what's already there for any task I know of.

It's a bit like obsessing over patch releases of some software after a major upgrade already solved the original problem long ago.

Above GLM 5.3, nice! That is a very capable model. I do wish that we will see some smaller "flash" models again though - running this one locally is tough (very costly).

Very keen to try this out tonight. What coding harness do people like to use with these models?

Thank you deepseek, we are eating good today.

Looks very impressive especially considering the price and speed. Let's wait for AA to confirm how well their benchmarks hold up.

I'd never heard of the BabyVision benchmark they do so well on. Pretty interesting stuff:

Is it coming to OpenCode et al?

It's better than GLM 5.3 and Kimi K3 and way cheaper.

Those are crazy numbers for a Flash model. Hopefully they can scale what they are doing to 4.1 Pro.

So this is the reason for the crash a few days ago.

beating K3 and GLM-5.3 is kinda insane

Another big win for opensource AI.

BTW who would have thought China would be the champion of freedom and opensource in the AI arena, while US is fighting for corporate/government control.

"a minor update" they say before showing off benchmarks that display a substantial improvement.

floooof • today at 9:08 AM

they must've been using this since 2-3 days when it became free again in OpenCode, it's noticeable smarter, beats GLM

We're in a crisis

Censored, no surprise

Those benchmarks can't possibly be real, right? Right? <insert padme 4-panel meme here>
