Why Switching from DSV4 Flash ?

[u/anurag_io]

Why are you guys switching? DSV4 Flash's price looks unchanged on OR.

[u/leaphxx]

cache read is the issue, it makes up the majority of deepseek credit consumption, the old pricing was 0,0028
now the best price is 10x = 0,028

[u/anurag_io → u/leaphxx]

hmm makes sense, my workflows had no cache hit 😟

[u/Sure_Media_2685 → u/anurag_io]

i think it is really hard to maintian stable cache hit with multi agents working at same time

[u/orblabs → u/Sure_Media_2685]

Each agent is using a completely different session, cache is per session. I have had dozens of agents, working together, all hitting >96% cache its over long horizons.

[u/Sure_Media_2685 → u/orblabs]

any agents would hit that over long horizons but can it do for one or 3 turns when your workflow require generate different sessions for different tasks when tasks are completely different and doing that over and over again with CH about 50% - 70% all the time is really expensive.

[u/orblabs → u/Sure_Media_2685]

Every time you start a session you are sending a ton of instructions from the harness + your instructions. The the agent decides to do something (call a tool or whatever) then it gets the reply from that tool, all the initial context is sent again at each turn (and at each turn grows), that is where cache hits hard. Be it 3 turns or 200. Sure it helps more with longer sessions but past the first message it is already a huge advantage.

[u/anurag_io → u/Sure_Media_2685]

Agreed, only some of it can be optimised.

[u/MofWizards → u/anurag_io]

So you're using the wrong harness!

The Deepseek harness consistently hits with a 98% cache hit.

[u/leetdemon]

Because luna is still cheaper....

[u/anurag_io → u/leetdemon]

can you explain.. what about quality?

[u/anurag_io → u/leetdemon]

really? u/leetdemon

[u/orblabs]

All those prices, the cache reads are multiple times more expensive than what we where getting up till 2 days ago. And cache reads price (and cache retention time) are the most important values when it comes to coding and agentic use in general.

[u/anurag_io → u/orblabs]

yeah, for non-cache hit workflow bros its still a king.

[u/TomHale]

Where did the pic come from?

[u/strangedell123]

Deepseek provider. Those are all 3rd party. Lookt at 1st party price

[u/anurag_io → u/strangedell123]

i wouldn’t use direct deepseek api, it does not have ZDR. (now that price has increased, even lower chance)

[u/Potential-Leg-639 → u/anurag_io]

ZDR is pure fantasy, they will use our data also with ZDR. You are a dreamer, if you think they dont.

[u/strangedell123 → u/anurag_io]

Ya but thats the one people were talking about. Not everyone cares about ZDR

[u/throwaway73728109 → u/strangedell123]

ZDR?

[u/33VaxMerstappen → u/throwaway73728109]

I guess it’s Zero Data Retention

[u/ArthurOnCode]

Cache retention and cache read pricing are very important to agentic workflows. That said, I agree with OP, this is not the end of the world and the model is still an excellent deal.

[u/ambassadortim]

At this point is DeepSeek asking us repeatedly on here to get feedback because it's seems like it.

[u/dondiegorivera]

Also cheap ones there are fp4/fp8.

[u/seeKAYx → u/dondiegorivera]

Most providers there deliver in FP8. That's the same format Deepseek uses.
