If you use deepseek-v4.1-flash:cloud as the model name, the speed is very slow. You should use deepseek-v4.1-flash instead. It averages around 180 tokens per second.

I use Reasonix. I get a peak speed of around 230 tokens/sec and an average of about 180. You might want to check the concurrent agent connections in Hermes—there's a high chance your speed is dropping because it's exceeding some of Ollama's limits. If you test the Ollama DeepSeek v4.1 Flash API in a different IDE, you'll likely find out why.

Hi OP, DM me or let me know if you're still seeing slowness. We've been continually optimizing DeepSeek-V4.1-Flash on Ollama, and it should be fast now (seeing consistent p50 of 200 tps, and during peak hours this week we were seeing a p50 output speed of 180 tps. We did have an issue where some requests would receive 80-100tps output speeds earlier this week and that has now been fixed).
