1 · How to choose

Use Flash by default; pay the Pro multiplier only when it helps

Both routes share one token pool. Flash uses one plan token per raw input/output token. Pro uses ceil(tokens × 87 / 28) plan tokens, or about 3.11×, so a 25M five-hour pool represents about 8.05M raw Pro tokens if every request uses Pro.

DeepSeek V4 Flash

Default · 1×

deepseek-v4-flash

Use for everyday coding, repository exploration, chat, repeated tool calls, and higher-volume agent work.

DeepSeek V4 Pro

Hard tasks · ≈3.11×

deepseek-v4-pro

Switch to Pro for difficult reasoning, architecture decisions, deep reviews, and final-pass verification where quality matters more than token volume.

2 · Switch models

Keep the Key and Base URL; change only model

Start with deepseek-v4-flash. For a hard reasoning or review pass, replace the request's model value with deepseek-v4-pro. Switch back to Flash for routine tool loops so the shared token pool lasts longer.

// Default
model: "deepseek-v4-flash"

// Hard task
model: "deepseek-v4-pro"

3–4 · Protocol, test, then Agent

The Key and models are shared; the wire contracts are not

Select the exact protocol your client sends. Each option below has a different endpoint, request body, and response shape, followed by a matching API test and Agent configuration.

These examples already use the API endpoint provided with the Token Plan athttps://api.deepseekv4pro.com/v1. Replace only YOUR-TOKEN-PLAN-KEY with the access Key delivered in Dashboard. This product does not transfer a DeepSeek account or credentials from the DeepSeek console.

Protocol A · Responses

OpenAI Responses

Public route configured

Base URL: https://api.deepseekv4pro.com/v1
Exact endpoint: https://api.deepseekv4pro.com/v1/responses
Authentication: Authorization: Bearer <access key>

Request → response contract

input request → output items and Responses events

Compatible tools

Codex

Do not mix /v1/responses, /v1/chat/completions, and /v1/messages. The Key and model aliases are shared; the wire contracts are not.

API connection test

Expected marker: responses-ok

curl https://api.deepseekv4pro.com/v1/responses \
  -H "Authorization: Bearer YOUR-TOKEN-PLAN-KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "deepseek-v4-flash",
    "input": "Reply with: responses-ok",
    "max_output_tokens": 32

# Put this in the shell that launches Codex:
# export DEEPSEEK_TOKEN_PLAN_KEY="YOUR-TOKEN-PLAN-KEY"

Switch model

Change only the top-level model value to deepseek-v4-flash or deepseek-v4-pro, then start a new Codex task.

Verify

Run codex with a small read-only prompt and confirm the request reaches the Responses route without an authentication or model error.

Requires an OpenAI Responses-compatible API route. The provided endpoint exposes /v1/responses for that purpose.
