Pretty sure Reflection-70B was a complete scam. They did the ole bait and switch. The model that they uploaded was completely under-performing compared to their own benchmarks and the "secret API" was just a GPT-4 & Claude wrapper.
I'm aware of the issue with their purported benchmarks, in fact some testing had Reflection 70B performing a bit worse than plain Llama-3.1 70B. Does G1 do any better?
