looks like https://github.com/deepseek-ai/DeepSeek-V3/issues/407

      const completion = await this.client.chat.completions.create(
        {
          messages: [{ role: 'user', content: prompt(type, name, comments) }],
          model: this.model, // deepseek-reasoner
        },
        {
          signal: controller.signal,
        },
      )

Same here and most of the time things just timeout. Sometimes the chat model works but I mostly get the same issue invalid json response body" for both

It is not supported by the deepseek-reasoner model so far.

The same thing happens here. I'm having to set a waiting time before each use to mitigate the problem a little.

Anyone found a solution? Or is it just a problem on DeepSeek's side, that we have no chance to fix ourselves?
Thanks!

Yes, exactly. I've switched to an OpenAI model in the API for now, and will
wait a couple weeks maybe till the boom around DeepSeek cools down a bit
and they upgrade their servers and implement some basic security features,
haha. And then switch back to DeepSeek in my API.

Facing the same issues, I am pushing 6-10 API requests at once, most of them fail, only works when I send one at a time.
Even the deepseek-coder one is giving the same problem

So it seems like a their issue? I have a 80% chance of getting it while using the api. Sometimes it works fine tho.

Yes, @Joonas12334 , sometimes it works, but it's awful because you never know when it's going to fail. That's why, even though ChatGPT's API is expensive, it offers much more reliability.

I just switched to google gemini. It's also fantastic if guided well. Also damn. It's really fast compared to deepseek. Howerver still eager to try out deepseek more when it becomes actually usable (if that ever happens)

their service status suggests that api performance has been degraded.... will this ever get better?

They probably can't handle the load at that super low price.

It would be useful to at least output some better error, like "Server is temporary down", to prevent people from spending time, wondering if they can do something to fix it.
