Model overview

DeepSeek-V4-Pro: features, use cases and important details

DeepSeek-V4-Pro is DeepSeek’s production V4 Pro model, generally available since August 13, 2026.

Verified model facts

DeepSeek documents a 1M-token context window, maximum 384K output, thinking and non-thinking modes, JSON output, tool calls, Responses API and Anthropic-compatible access.

Current status

It is active on the DeepSeek API with separate peak and off-peak prices.

Best fit

It fits long-context agents, coding, repository-scale work and production automation.

Limitations

Pricing varies by time window, no public knowledge cutoff is stated on the model pricing page, and long outputs can become expensive.

Get started

How to use this model

  1. Create a DeepSeek API key.
  2. Set model to deepseek-v4-pro.
  3. Choose thinking/non-thinking behavior and reasoning effort.
  4. Use JSON output, tool calls or Responses API as needed.
  5. Schedule cost-sensitive workloads during off-peak windows when practical.

Pricing

What does it cost?

Current DeepSeek-V4-Pro peak/off-peak pricing: cached input $0.022/$0.044 per 1M, uncached input $0.66/$1.32 per 1M, output $1.98/$3.96 per 1M (off-peak/peak).

Input$0.66 off-peak / $1.32 peak per 1M uncached input tokens
Output$1.98 off-peak / $3.96 peak per 1M output tokens
Simple summaryDeepSeek uses peak and off-peak billing; off-peak V4-Pro uncached input/output rates are $0.66/$1.98 per million tokens.

What stands out

  • Very large context/output
  • Low off-peak pricing
  • Tool and JSON support
  • Current production model

Things to consider

  • Peak pricing can be 2x off-peak
  • Proprietary API
  • No open weights claimed for Pro
Limitations

Important restrictions and trade-offs

  • Knowledge cutoff is not stated in the pricing docs
  • Agent/tool outputs still require validation
  • Long outputs can create large bills
SimplifyAITools verdict

Our editorial take

A strong current-value model for long-context agents, especially when workloads can take advantage of DeepSeek’s off-peak pricing.
