I only did a quick first test of DeepSeek V4 Pro 0813 tonight, so take this as a tiny sample, not a verdict.
The first Pro run failed. I put the same demo through Flash, and Flash completed it. I honestly did not expect that result, so I ran Pro a second time before writing this. Same failure.
The odd part is that it did not feel slow while generating. I was seeing roughly 80 to 90 tokens/s tonight. That looks fine on a counter, but it matters a lot less when the demo itself does not make it across the line.
For my next pass, I will put the same requests through ZenMux and record the model route and provider with each request. That makes the comparison easier to inspect. It still does not turn two failed runs into a benchmark.
My first impression is negative. Two runs are nowhere near enough for a broad claim, but two failures on a demo that Flash completed are worth writing down.
What are people seeing right now with V4 Pro 0813? If you tested it against Flash, did you keep the same prompt and setup, and did Pro actually finish the demo?
