DeepSeek V4 Flash Vision Exp Listed: $0.44 Input, 1049k Context Window

What's new

DeepSeek added DeepSeek V4 Flash Vision Exp to its lineup on 2026-08-21. It's an open-source model handling text+image inputs and returning text outputs, priced at $0.44 per 1M input tokens and $1.32 per 1M output tokens.

Why the context window matters

The 1049k token context is the headline spec here. For vision workloads that require processing long documents alongside images — think multi-page PDFs with diagrams, or large codebases with screenshots — that context ceiling gives you meaningful headroom without mid-task truncation.

Cost reality check

At $0.44 input / $1.32 output, this sits in budget-to-mid-range territory for vision models. The 3:1 output-to-input price ratio is fairly standard, so workloads that generate verbose outputs (detailed image descriptions, long-form analysis) will feel the output cost more than the input cost. If your use case is high-volume, low-output (classification, tagging, quick captions), the economics look better.

Being open-source also means self-hosting is on the table if you have the infrastructure — potentially dropping per-token costs to near zero at scale.

Who should care

• Developers building document-intelligence or visual-QA pipelines who need a large context window without paying frontier-model prices.
• Teams already using DeepSeek's API who want to consolidate vision and text workloads under one provider.
• Budget-conscious builders who want to benchmark a cheaper option before committing to pricier multimodal models.
