The true cost of the price increase for agentic coding.
Since the new price increases are not uniform across input/output/cached, we need to look at the typical token split for coding agents to determine the average price increase. Luckily Opencode publishes data on the typical token split per request.
Let's do the math.
###V4 Flash
Average request: 790 input, 280 output, 68,000 cached.
Old price cost per 1000 requests: $0.3794
New off-peak price cost per 1000 requests: $0.8346
###V4 Pro
Average request: 750 input, 290 output, 82,000 cached.
Old price cost per 1000 requests: $0.8758
New off-peak price cost per 1000 requests: $2.8732
###Comparison Table
Here's a table that compares new prices to old baseline.
| V4 Flash | V4 Pro
---------|----------|---------- Old price | 1x | 1x New off-peak price | 2.2x | 3.28x New peak price | 4.4x | 6.56x
