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

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

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).

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)

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.

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

Is it coming to OpenCode et al?
floooof
they must've been using this since 2-3 days when it became free again in OpenCode, it's noticeable smarter, beats GLM

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

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.

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.

So is this the first model that passed China's new export controls introduced yesterday?[1] It goes live November 15, but temporary pre-registration requirements took effect immediately after the announcement, ~20h-ish ago. [1] https://www.reddit.com/r/LocalLLaMA/comments/1x7g3zq/china_p...

The native web search api is 10x cheaper than OpenAIs. I hope they will release the web search api as a standalone API.

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

Censored, no surprise

My favorite model just got better. Gotta love what deepseek is doing

I really like the having DeepSeek Flash + Opus 5.5 as advisor/reviewer at the moment. I run through a $200 Claude Code subscription in less than 24 hours now just for a single project, and I hate fiddling with different accounts every day. Now that I get a 200 USD api credits inlcuded with the subscriptions I have rewritten my coding agent workflow completely.
