I'm a little skeptical of going below 4-bit quants due to the potential for significant degradation in quality. I'm running 4-bit quants on an RTX Pro 6000 rented for approximately $1/hour and getting about 1.2 million tokens out and 40 million tokens in per hour with caching. The quality of 4-bit quant is good enough for difficult but well-scoped coding tasks. Here is the inference stack I am using: <a href="https://www.reddit.com/r/BlackwellPerformance/s/FrKwk3GoDK" rel="nofollow">https://www.reddit.com/r/BlackwellPerformance/s/FrKwk3GoDK

  Can you say more about where you're renting the RTX Pro 6000 for $1/hour?

    I am renting spot VMs from Nebius. I've tried a variety of other providers like Vast and Spheron. Vast worked well for renting 5090s but I like the large memory and pricing I'm getting at Nebius for RTX Pro 6000. The extra RAM really matters because I need PLE to offload the ngram to RAM.
