Honestly cerebras is good. I can recommend it. I talked to their team once on discord as a literal free user so that was something really nice personally
They were also the faster one compared to groq but they were always a little slow on adding new models compared to groq but not sure what changed right now.
Definitely recommend cerebras tho now that groq's been eaten up from inside basically
I had the feeling that Cerebras only supports smaller modes. Maybe something to do with their hardware arch? I never dove into it. I wanted to use Kimi K2 fast for coding and Groq was the only fast provider at the time
