Getting started
Call DeepSeek V4 Pro through AI Gateway with the AI SDK generateText and streamText functions, or through the OpenAI Chat Completions, OpenAI Responses, and Anthropic Messages APIs by changing the base URL. AI Gateway authenticates the request and routes it to an available provider.
Install the AI SDK (pnpm add ai dotenv), create an API key from the API Keys page, and set it as AI_GATEWAY_API_KEY in your environment. Full setup is covered in the text generation quickstart.
import { generateText } from 'ai';import 'dotenv/config';
async function main() { const result = await generateText({ model: 'deepseek/deepseek-v4-pro', prompt: 'Why is the sky blue?', });
console.log(result.text);}
main().catch(console.error);Top-level parameters
The same DeepSeek V4 Pro request in each API format AI Gateway supports.
import { generateText } from 'ai';import 'dotenv/config';
async function main() { const result = await generateText({ model: 'deepseek/deepseek-v4-pro', system: 'You are a concise technical assistant.', prompt: 'Summarize the tradeoffs between static generation and SSR.', maxOutputTokens: 1024, });
console.log(result.text);}
main().catch(console.error);Standard parameters like prompt, messages, temperature, and tools work as documented in the AI SDK docs. These are the parameters with model-specific behavior.
| Parameter | Type | Required | Description |
|---|---|---|---|
model | string | Yes | Model ID in the form creator/model, e.g. deepseek/deepseek-v4-pro. AI Gateway routes the request to an available provider. |
maxOutputTokens | number | No | Hard cap on generated tokens. DeepSeek V4 Pro supports up to 1,048,600 output tokens. Reasoning tokens count toward this limit. |
reasoning | 'provider-default' | 'none' | 'minimal' | 'low' | 'medium' | 'high' | 'xhigh' | No | Provider-agnostic reasoning effort, available in AI SDK 7 or later. Maps to the provider’s native reasoning configuration; reasoning settings under providerOptions take precedence when both are set. See the Reasoning section below. |
providerOptions | Record<string, JSONValue> | No | AI Gateway routing options under gateway, plus any provider-native options under the provider’s own namespace — see the table below. |
Input limits
| Input | Formats | Sources | Max count | Max size | Limits |
|---|---|---|---|---|---|

Provider options
Set AI Gateway routing options under providerOptions.gateway. For provider-specific options, pass them under the provider’s namespace as documented by the AI SDK.
Learn more in the AI SDK deepseek provider docs.
import { generateText } from 'ai';import 'dotenv/config';
async function main() { const result = await generateText({ model: 'deepseek/deepseek-v4-pro', prompt: 'Why is the sky blue?', providerOptions: { gateway: { only: ['deepseek', 'novita'], }, }, });
console.log(result.text);}
main().catch(console.error);These AI Gateway routing options apply to every model. Provider-specific options pass through under the provider’s own namespace (for example providerOptions.anthropic) exactly as documented by the AI SDK.
| Parameter | Type | Required | Description |
|---|---|---|---|
providerOptions.gateway.only | string[] | No | Restrict routing to these provider slugs. Requests fail over only within the listed providers. |
providerOptions.gateway.order | string[] | No | Preferred provider order. Listed providers are tried first; unlisted providers remain available as fallbacks. |
providerOptions.gateway.sort | 'cost' | 'ttft' | 'tps' | No | Rank candidate providers by price, time to first token, or tokens per second instead of the default routing order. |
providerOptions.gateway.zeroDataRetention | boolean | No | Route only to providers with a zero-data-retention policy for this model. |
Routing across providers
AI Gateway serves the same model through multiple providers and fails over automatically. order expresses a preference while keeping every provider eligible; only is a hard allowlist — if none of the listed providers are available the request fails instead of falling back.
Options under a provider's own namespace (for example providerOptions.anthropic) are forwarded to that provider with the request. Providers ignore option namespaces that don't apply to them, so it is safe to set provider options alongside gateway routing options.
Reasoning
AI Gateway bridges reasoning across every API format. The AI SDK exposes a provider-agnostic top-level reasoning level (none, minimal, low, medium, high, or xhigh); the Chat Completions and Responses formats take the same effort under reasoning.effort; and the Anthropic Messages format uses a native thinking token budget. Whichever you send, the gateway maps it to the target model’s native configuration, converting between effort levels and token budgets as needed. Reasoning-related settings under providerOptions take full precedence over the top-level reasoning value and are never merged. Reasoning tokens typically count toward your output-token usage, though how they’re reported and billed varies by provider.
Learn more in the AI Gateway reasoning guide.
import { generateText } from 'ai';import 'dotenv/config';
async function main() { const result = await generateText({ model: 'deepseek/deepseek-v4-pro', prompt: 'Explain the Monty Hall problem step by step.', reasoning: 'high', });
console.log(result.text);}
main().catch(console.error);Tool calling
Expose tools the model can call. Define each tool’s inputs with a Zod schema.
import { generateText, tool } from 'ai';import { z } from 'zod';import 'dotenv/config';
async function main() { const result = await generateText({ model: 'deepseek/deepseek-v4-pro', prompt: 'What is the weather in San Francisco?', tools: { getWeather: tool({ description: 'Get the current weather for a location', inputSchema: z.object({ location: z.string() }), execute: async ({ location }) => ({ location, temperatureC: 18 }), }), }, });
console.log(result.text);}

DeepSeek V4 Pro was released April 23, 2026 as the high-capability tier of DeepSeek's V4 generation. The V4 series introduces a hybrid attention architecture that combines Compressed Sparse Attention (CSA) with Heavily Compressed Attention (HCA), and uses ManifoldConstrained Hyper-Connections (mHC) in place of standard residual connections. The combination supports efficient inference at the 1.0M tokens window.
DeepSeek V4 Pro is positioned for complex reasoning, multi-step problem solving, and agentic workflows. Tool use, reasoning, and implicit caching are all supported, so DeepSeek V4 Pro fits planner-style pipelines where the model decides on tool calls, integrates results, and iterates toward an answer. Maximum output is 1.0M tokens, which gives long-form reasoning chains and tool-call sequences room to complete in a single response.
Access is through AI Gateway with an AI Gateway API key or OIDC token. You can integrate through the AI SDK, Chat Completions, Responses, or Messages API formats. Implicit caching applies when a long input prefix repeats across calls, charging the cached input rate instead of the standard input rate for cached tokens.
Copy link to headingWhat To Consider When Choosing a Provider
- Configuration: DeepSeek V4 Pro is priced higher than the V4 Flash variant. If your workload is short-form instruction following or classification, DeepSeek V4 Flash delivers similar output limits at lower per-token rates.
- Zero Data Retention: Zero Data Retention is available for this model. It is offered on a per-provider and model basis. See the documentation for details.
- Authentication: AI Gateway authenticates requests using an API key or OIDC token. You do not need to manage provider credentials directly.
Copy link to headingWhen to Use DeepSeek V4 Pro
Best for
- Complex reasoning workloads: Analytical research, technical synthesis, and structured derivation benefit from the 1.0M tokens window and V4 architecture
- Multi-step agent pipelines: Planning, tool calls, and result integration combine in a single endpoint
- Software engineering automation: Reasoning and reliable tool use across long context support code-generation pipelines
- Multi-format API integrations: AI SDK, Chat Completions, Responses, and Messages API formats route to the same high-capability model
Consider alternatives when
- Short-form throughput: Use DeepSeek V4 Flash for classification, routing, and instruction following at lower per-token cost
- MIT-licensed reasoning: DeepSeek-R1 remains the open-weights reasoning specialist when license terms drive the selection
- Earlier-generation cost: DeepSeek V3 family models may meet capability needs at lower cost when V4 context and architecture aren't required
Copy link to headingConclusion
DeepSeek V4 Pro is the capability tier of the V4 generation, suited to complex reasoning and agentic workloads at the 1.0M tokens window. For short-form, high-volume tasks within the same generation, DeepSeek V4 Flash is the cost-efficient alternative.
