Source-tracked model comparison

How do GPT-4o Mini and DeepSeek V4 Flash API costs compare for structured extraction?

Compare verified pricing and model limits for low-cost structured extraction. The cost example uses a structured data extraction workload and does not assume equal model quality.

Direct cost answer: GPT-4o mini is estimated at $82.50 per month and DeepSeek V4 Flash non-thinking at $56.28 for 4,000 input tokens, 500 output tokens, and 100,000 monthly requests. DeepSeek V4 Flash non-thinking is $26.22 lower under these assumptions. This does not identify a quality winner.

StackLens assessment

Questions to answer before choosing

Is provider availability acceptable for the target regions?
Does the extraction schema work reliably on representative records?
How many repair calls are needed after invalid output?

Workload caveat

What this estimate leaves out

Document parsing, OCR, validation infrastructure, and failed-record handling are outside this token estimate.

Latency, reliability, output quality, retries, regional processing, and provider-specific tool charges can change the practical decision.
