Key Info
A developer notes that renting 1,000 GPUs—already very hard to find—only gives a generic cluster setup, and such setups cannot match the custom datacenter optimization behind DeepSeek-level inference quality.
Highlights
- Reaching DeepSeek-quality inference takes months of careful engineering, not just raw GPU capacity.
- Cache hit rate is a better indicator of real optimization than headline prices.
- Generic rented clusters miss the many small customizations that create large efficiency gaps.
- Be wary of suspiciously cheap API deals: poor cache rates can hide true costs until you measure them in production.
