Maybe the Chinese are playing the long game by trying to bankrupt the US competition? Because there's no way this is financially viable.

Federal ban incoming then. They did it with cars already.

Won't that be impossible as long as VPN is viable?

AFAIK the two most popular open source harnesses right now are OpenCode and Pi. They take a pretty different approach, OpenCode includes a lot of features while Pi is very minimal by design and focused on extensibility, to the point where many people are just asking Pi to write a plugin for itself whenever they want it to have a new feature. I personally like Pi's philosophy more and I think its developer justified t…

I'm more curious about the caching: > (2) For all models, the input cache hit price has been reduced to 1/10 of the launch price. This price adjustment takes effect from 2026/4/26 12:15 UTC. There is no end date. Currently, it's 2% of the input price for DeepSeek V4 Flash and 0.8% with this new V4 Pro pricing, which is extremely low compared to competitors to the point that it affects the unit economics a bit and I t…

Sonnet : Cache Read $0.30 Gemini 3.5 flash : Cache Read $0.15

Anthropic's caching requires you to pay a $0.75/Mtok for Sonnet and $1.25/MTok for Opus as a surcharge on top of the original input token cost. It's not even automatic.

If you are reading ~8 times (8 total back and forth tool calls) that means that cache reads in some sense cost ~$0.4 / M toks (Amortizing the write surcharge over all reads).

It's really quite ridiculously expensive considering what you are paying for is some residence on a VRAM that sometimes gets offloaded to NVMe.

Once they have their own coding agent which they seem to be working towards, I may start predominantly using their models. They seem to be doing all the "right" things, open sourcing models, publishing research, and keeping prices low for everyone.

You can use V4 Pro with Claude Code [1]. I tried it and it's impressive. [1]: https://api-docs.deepseek.com/quick_start/agent_integrations...

I've been using V4 flash consistently with Claude. Pretty great fast and darn cheap. I use it about 3h/day and so far haven't crossed $1 USD/week.

FWIW, I this is what I have in my settings.json

For Sonnet, that's 10% of input cost (and requires paying for the cache) For Gemini 3.5 Flash, it's also 10% of input cost. Which is why 2%/0.8% change the economics in a meaningful way, given the input/cache-heavy way agents operate.

And their disk-based caching is amazing. I got a long 700k context session spanning more than a week, with pauses in between that was longer than a day, and some rewinds mixed in as well.

Stats from pi:

↑400k ↓438k R432M 71.9%/1.0M

Half a billion tokens, $2.12

Oh damn, I haven't noticed because my browser removes the referer header. But I think the image on the block page is a pretty good answer to why he did that.

What's the image trying to convey? Genuine question, I just come here to read nerd stuff and I'm not aware of any controversy

This looks suspiciously cheap.

The same model hosted by other providers is much more expensive [0]. So either DeepSeek can host it much cheaper than anyone else, or their business model is different. I suspect the latter, especially since their privacy policy [1] says personal data, including “User Input,” can be used "To improve and develop the Services and to train and improve our technology".
