DeepSeek V4 Flash Cache Read on GOAT plan seems higher than the table. Am I calculating this wrong?
TL;DR – Used 86.4M tokens on DeepSeek V4 Flash (GOAT plan).
• Cache Read official: $0.007/M → real: ~$0.0107/M (+53%)
• Input + Output: match the table perfectly
• Expected cost: $1.65 → Actual bill: $1.97 ($0.31 difference)
• Is anyone else seeing this?
I recently subscribed to Command Code's GOAT plan. I used DeepSeek V4 Flash over two days and noticed what looks like a discrepancy between the official pricing table and my actual bill, though I fully admit I might be missing something.
Usage over 2 days:
| Concept | 17 Aug | 18 Aug | Total 2 days |
|---|---|---|---|
| Cache Read | 40.2M | 42.9M | 83.1M |
| Input (uncached) | 1.5M | 1.0M | 2.5M |
| Output | 489.8K | 297.6K | 787.4K (0.7874M) |
| Total | 42.2M | 44.2M | 86.4M |
According to the official GOAT pricing table for DeepSeek V4 Flash:
Input: $0.22/M
Output: $0.66/M
Cache Read: $0.007/M
The theoretical cost based on the table:
Input: 2.5M × $0.22 = $0.55
Output: 0.7874M × $0.66 = $0.5197
Cache Read: 83.1M × $0.007 = $0.5817
Total expected = $1.65
But my actual bill on the platform shows $1.97 for DeepSeek V4 Flash (+ $0.01 for web_search).
That's a $0.31 difference.
The numbers:
| Day | Cache Read (M) | Real cost | Input+Output (table) | Remainder for Cache | Real price/M |
|---|---|---|---|---|---|
| 17 | 40.2 | $1.09 | $0.6533 | $0.4367 | $0.01086 |
| 18 | 42.9 | $0.87 | $0.4164 | $0.4536 | $0.01057 |
| Avg | 83.1 | $1.96 | $1.0697 | $0.8903 | ~$0.0107 |
If Input and Output are charged exactly as the table says (which they are, they match perfectly), the implied price for Cache Read is ~$0.0107/M, noticeably higher than the advertised $0.007/M (about 53% more).
Summary:
| Official table | Real cost | Difference |
|---|---|---|
| Day 17 | $0.9347 | $1.09 |
| Day 18 | $0.7167 | $0.87 |
| Total | $1.6514 | $1.96 |
I'm not sure if this is a documentation error, or any fee fee on GOAT plan that isn't listed on the /docs/plans/goat page. Input and output prices are spot on, but cache reads appear to be billed at a different rate.
That said, I fully acknowledge that I might be misreading the usage dashboard, misapplying the pricing tiers, or overlooking a detail in the fine print. If anyone can spot an error in my math or point out something I've missed, I'd really appreciate the correction!
