The development
DeepSeek has made its 75 percent discount on V4-Pro permanent, according to The Decoder’s May 23 report. The reported rates are $0.435 per million uncached input tokens and $0.87 per million output tokens. The output rate is about 34.5 times below GPT-5.5’s listed $30 per million at that time. This unit-price gap matters for token-intensive applications, but token consumption and output quality determine whether a completed task actually costs less.

Modelwire analysis
Analyst takeOur AI-generated reading of the wider context and the next developments to watch.
Making the discount permanent changes the planning horizon: teams can compare a recurring published rate rather than assume a promotion will end. It still leaves the economics of their own workloads unresolved.
For an agent that calls a model repeatedly, a token-price difference can accumulate across a workflow. But cheaper tokens do not guarantee cheaper accepted results if the model needs more attempts or produces errors. Teams should compare the same tasks, quality criteria and total usage before switching.
Watch for task-level comparisons reporting token consumption, retries, latency and accepted outputs. Those measurements would show whether the advertised unit-price advantage survives actual deployment constraints.
