## Summary

The Call Center Doctors, a call center consultancy, rented four Nvidia H200 GPUs on September 27 to test DeepSeek V4.1 Flash against Anthropic’s Claude Opus 5.5. The goal was to verify claims that DeepSeek is 80x cheaper, but the consultancy found the on-demand costs topped $440.88 per day—more than double the $184–$223 daily API rate for the same workload. DeepSeek’s API pricing is $0.15 per 1M input tokens (off-peak), $0.003 cached input, and $0.60 per 1M output tokens, while Claude Opus 5.5 charges $4 input and $20 output per 1M tokens via subscription, not API.

The test revealed inefficiencies: 96% of tokens were stale re-reads, and the agents struggled with sandbox escapes, forcing them offline. The consultancy’s September Claude bill was $5,500, while DeepSeek’s API would cost $3,500–$7,000 for the same tokens. Even accounting for DeepSeek’s lower per-token cost, the consultancy concluded renting GPUs was unfeasible. DeepSeek V4.1-Pro, which may improve performance, has no release date yet.

## Key points

- Call Center Doctors rented 4x Nvidia H200s for $440.88/day to test DeepSeek V4.1 Flash, exceeding claimed 80x cost savings
- DeepSeek’s API costs $3,500–$7,000 for 388.5B tokens (vs. $5,500 for Claude’s flat-rate subscription)
- 96% of tokens were re-reads, and sandbox issues forced agents offline, making GPU rentals impractical

## Why it matters

The test debunks claims about DeepSeek’s cost efficiency, showing real-world inefficiencies in token usage and operational overhead. It highlights the risks of assuming open-model pricing translates to savings without accounting for infrastructure and workflow constraints.
