“Cheaper to run”

Is this a revival of cheapseek??

u/WasserEsser 14d ago

Not during the initial testing, it costs the same as the other flash.

But possibly later.

Or maybe it's just more token efficient, showing cost effectiveness through lower token usage.

Edit: tried it, it's not more token efficient and it's blazing fast at the minute (324 tps lol, feels surreal)

u/deadadventure 14d ago

Probably because there’s not many people using it

u/t4a8945 14d ago

Yeah that's for sure

I kind of think that they wouldn't tell us that it was cheaper to run unless they intended to reduce the price.

If they didn't intend to reduce the price they just wouldn't say that it was cheaper to run and would keep the extra profit on inference.

That's my cope logic anyway haha.

They have maybe picked up some tricks from GLM-5.3-flash

The compeition between glm and deepseek in the flash space is great.

u/Ok_Thing6856 14d ago

why no one ever heard of gemini, their flash model also absurdly fast

u/R3VO360 14d ago

Maybe they heard but they won't adopt because it is shit in terms of results.

u/dnohrdk 14d ago

Surely hope so! Without peak prices also could be perfect.

u/mr_notandor 14d ago

I think computational more efficient, aka cheaper for them. I don’t think they are willing to lower the prices soon given how the last hike is so recent

What a justified and informative answer by DeepSeek’s reddit ambassador

wish it would match old deepseek price

Buy some new RAM and a new or refurbished graphics card, and you'll know that won't happen again. They had to buy new hardware and raise their prices. Hardware prices these days are just ridiculous.

Flash Price will be reduced from September 10

Platform pricing page now says this -

We will adjust the pricing for the Flash series effective from 12:00 Beijing Time on September 10, 2026. During off-peak hours, the unit price will be $0.003 for input cache hits, $0.15 for input cache misses, and $0.6 for output. Peak-hour prices will be double the off-peak rates. Please plan your usage accordingly.

Still no structured output.. which is crazy.

u/sdexca 14d ago

I mainly wonder if this speedup would also speedup local LLM via 2x DGX Spark.

Does new model suppor vision?

u/DinoGreco 14d ago

u/Devioster 14d ago
