Hard to calculate exactly without an input/output split but I did the math and for 831,962,136 tokens, Anthropic Opus 4.7 would cost:
- 100% input (floor, unrealistic): 831.96M × $5/M = $4,159.81
- 90/10 (typical for coding agents like opencode — most tokens are codebase context re-fed each turn): $3,743.83 $2,079.91 = $5,823.74
- 80/20 (more conservative): $3,327.85 $4,159.81 = $7,487.66
- 50/50 (worst plausible case): $2,079.90 $10,399.53 = $12,479.43
So that $10.57 DeepSeek bill would probably become roughly $5,000–8,000 on Claude Opus 4.7.
In other words, DeepSeek is 500–700× cheaper, for similar-ish capabilities.
Now you start to understand why Anthropic is worried...
Is DeepSeek V4 Pro cheap?
I consumed 831,962,136 tokens in under 2 days and paid $10 for it.
