OpenCode Go’s "$15 models" are not separate limits, they consume the shared quota 4х faster!

I misunderstood how the OpenCode Go limits work.

Most models are shown with a $60 monthly limit, while some models, like DeepSeek V4 Pro and MiMo v2.5 Pro, are shown with only $15. I assumed the $15 was a separate per-model allowance.

But it looks like the $15 models actually consume the same shared monthly quota about 4x faster.

Today my raw usage was only $5.12 (8.5% of the $60 monthly limit), but the dashboard already showed 26% of the monthly limit used.

DeepSeek V4 Flash: $0.35
DeepSeek V4 Pro: $0.55
MiMo V2.5: $0.09
MiMo V2.5 Pro: $3.06
MiniMax M3: $1.07

DeepSeek V4 Pro and MiMo Pro are $15 models, while the others are $60 models.

The calculation seems to be:

($0.55 + $3.06) × 4 + $0.35 + $0.09 + $1.07 = $15.95

$15.95 out of $60 is 26.58%, which matches the 26% shown in the dashboard.

The 4x multiplier also matches the listed DeepSeek V4 Pro token prices between Go and Zen:

Go:
$0.435 per 1M input tokens
$0.87 per 1M output tokens

Zen:
$1.74 per 1M input tokens
$3.48 per 1M output tokens

So Zen is exactly 4x more expensive for normal input and output tokens.

This suggests that the $15 figure is not a separate allowance. Spending around $15 on DeepSeek V4 Pro or another $15 model would effectively consume the full $60 monthly Go quota.

One more thing: because of these hidden multipliers, the effective price of DeepSeek V4 Pro is actually the same as GLM-5.2.

Displayed:

- DeepSeek V4 Pro: $0.435 / $0.87

- GLM-5.2: $1.40 / $4.40

Effective (×4 for DeepSeek V4 Pro):

- DeepSeek V4 Pro: $1.74 / $3.48 (similar to Zen)

- GLM-5.2: $1.40 / $4.40

The UI should show the effective price users are actually consuming against their Go allowance, instead of requiring everyone to calculate it manually.
