DeepSeek V4 Pro at 75% off until 31 May

A few days ago we were hearing about how the "free lunch is over", now we're seeing discounts and increased usage limits.

Is anyone concerned about these services and China’s National Intelligence Law?

Per 1M tokens (input cache hit / input cache miss / output) v4-pro (75% off): $0.003625 / $0.435 / $0.87 v4-pro (regular): $0.0145 / $1.74 / $3.48 v4-flash: $0.0028 / $0.14 / $0.28 that is damn cheap.

I've been using DeepSeek V4 a lot in the last week and I am very happy with it. If you have a really gnarly bug, you might need a SOTA model like Opus. For most things it is very very good, and costs significantly less (even without the discount). I've been using it as part of a complex DOS game decompilation project[0]. I'm working on refactoring the software rendering pipeline so that we can add GPU rendering. The hardest part of this so far is converting the 90's polygon rendering from screen to world space. It spun its wheels a few times doing a large mostly mechanical change. After resetting and improving my prompts it was able to get through it. I'm using Matt Pocock's skills[1] for this work, which has been quite nice. [0]: https://github.com/FatalDecomp/ROLLER [1]: https://github.com/mattpocock/skills

What coding agent(ideally CLI) have people found works well with this? Occasionally I go and try different agents with openrouter models, but nothing seems to really get close to the proprietary ones like claude-code.

I find it hard to understand why nobody in this thread considers that the current pricing might still be below cost. The discount was supposed to end on May 5, and then shortly after that they extended it to May 31. They clearly made a judgment call there, rather than treating it as a desperate loss-leader. If you have actually used DeepSeek, you would notice that the cache-hit rate is extremely high, and the cache invalidation window is much longer than every other provider's. That suggests DeepSeek is simply much better at utilizing its infrastructure than other vendors. I am also highly skeptical that the average user's input is worth more than the API cost of processing it. Do people really think DeepSeek researchers enjoy panning for gold in a river of boilerplate and half-baked code?

Have any regular Opus users taken V4 for a spin? What’s your take?

Anecdatally, out of all the popular LLMs I’ve only found Gemini to be any use for entry-level Ford Power Stroke Diesel mechanics and diagnostics. :)
