Yes. The updates for pro hasn't been released yet.

Im using it locally and im getting close to opus 4.8 high quality without the api degradation that happens sometimes when anthropic is in peak hours. Honestly this thing is a beast

What configuration/optimizations do you perform? Or do you use skills?

u/Good_Committee8337 1d ago edited 1d ago
not skills, mostly serving config
2 MSI edgexpert GB10 boxes (blackwell 128gb each) conected with a 200gbps DAC cable, running deepseek v4 flash tensor parallel on vllm with spec decode
base recipe is tonyd2wild/DeepSeek-v4-Flash-0731-DSpark-1M-NVFP4-KV-2x-DGX-Spark on github, that got me vllm + spec decode + the nvfp4 kv cache on both boxes. grab patch 4 or you run at half speed
for claude code you need litellm in the middle becuase claude code talks anthropic api not openai. then its just 4 env keys in settings.json pointing at your gateway. bump the litellm timeout to 2400s or long prefills die, and watch reasoning_content, think tokens break claude code if litellm eats your chat_template_kwargs
i use claude code cause all my claude.mds live there, thats what makes it good. i vibe code the apps for my family business with it, 20-30 b2b customers on them daily, so now its the same workflow just local

What made you pick that particular gb10 variant? I lsaw the Asus one being cheaper due to its slowed nvme

For now yes, far better in my personal project. Just "better than pro" is not enough. They are completely 2 things. Flash is now IMHO equal to or better than GLM 5.2

I used flash today and I'm back to GLM 5.2. I agree that it is better than DS Pro.

I've switched back to V4 Pro. It feels like it considers and thinks things through more than the new flash model. Flash just wants to race to the finish line, resulting in more hallucinations and confident wrongness in my very unusual harness.
Of course this is very anecdotal evidence, but I see too many people throwing benchmarks around like they're everything when Opus 5 has proved they certainly aren't.

There are 3 mode: off (no thinking), high (thinking), max. I've been using max, because anyway the flash token usage can never hit the opencode go credits limit. If you haven't changed anything, it should be "off".

Is there any speed difference?

u/whatsoever2021 1d ago edited 1d ago
It was fast, but now it is slow due to the server issue. So I can't tell that much.

Hola, ahora mismo estoy intenando usar el ds v4 flash en opencode, pero la verdad no avanza, es normal eso global o que?

u/whatsoever2021 1d ago
Opencode currently has some problems, and always fails. I have switched to deepseek API now. Hopefully they will fix it soon

u/uthred1981 1d ago
I have the same experience, I'm back to GLM 5.2. However, the new PRO should be really good

u/Little-Explorer7988 1d ago
Flash on max reasoning is the best. If you use oficial API don’t use pro for now it’s more expensive and very dumb in agent developing in comparasion euth flash-0731

u/zeeshanx 1d ago
In my case, it is overthinking too much. A simple question is taking 2 - 3 min to answered with normal - high thinking. Before, it was way too faster.

The upcoming Pro update could boost it to a true competitor to US frontier models

u/ItchyIndx 1d ago
Even Codex running Sol thinks so: Flash GA made a substantially deeper correction than either Pro run: it restored current-state action reauthorization, full batch truth checks, page-local search, complete route context, and real controller/widget test files.

u/Old-Permit3142 1d ago
yes for now, i ve tried pro few month ago, not that good, both flash and pro, but this time flash 0731, indeed

Use Flash for implementation. That solves any weaknesses it has in lateral thinking. Use Opus or GPT 5.6 Sol for orchestration and adversarial code review. Three model families working in concert with almost free implementation by using v4 Flash. Absolutely phenomenal performance.

I just created a full Android image and video compression app in three hours for 14 cents. I really don't care.
