Deepseek

Supercharge your AI agent with DeepSeek's reasoning models

Give your AI agent access to DeepSeek's powerful language models for deeper reasoning and more accurate answers. The agent uses DeepSeek-Chat for general conversations and DeepSeek-Reasoner for complex problem-solving, delivering thoughtful responses that go beyond surface-level answers.

Chosen by 800+ global brands across industries

Reasoning and generation on demand

Your agent taps into DeepSeek's chat completion and reasoning APIs to produce nuanced, context-aware responses with tool calling, structured output, and thinking mode capabilities.

Generate Chat Completions

A customer asks a complex question. Your AI agent routes the conversation through DeepSeek's Chat Completion API, selecting the deepseek-chat model with appropriate temperature and token limits. The response arrives with the nuance and accuracy of a frontier language model.

Enable Deep Reasoning

A customer poses a multi-step technical problem. Your agent switches to the deepseek-reasoner model with thinking mode enabled, allowing the model to reason step by step before answering. Complex logic, calculations, and structured analysis become part of the conversation.

Call Functions Dynamically

Your agent needs to look up data while answering a customer. Using DeepSeek's tool calling capability, the model identifies which function to call, provides the parameters, and incorporates the returned data into its response, all within a single interaction.

Use Anthropic-Compatible Format

Your existing workflows use the Anthropic Messages API format. The agent routes requests through DeepSeek's Anthropic-compatible endpoint, supporting system prompts, tool calling, and extended thinking without changing your integration architecture.

Check Available Models

Your team wants to verify which DeepSeek models are currently live. The agent queries the List Models endpoint and returns the available model IDs, ownership details, and availability status so you always know what capabilities are accessible.

Monitor API Balance

Before launching a high-volume campaign, your agent checks the account balance using the Get User Balance endpoint. It returns granted and topped-up balances broken down by currency, so you can confirm sufficient credits are available for upcoming API calls.

Use Cases

Smarter conversations powered by reasoning

See how businesses leverage DeepSeek's chain-of-thought reasoning and chat models to deliver expert-level answers through their AI agents.

Technical Support That Actually Understands the Problem

A developer asks why their API returns a 429 rate limit error intermittently. Your AI Agent activates DeepSeek-Reasoner with thinking mode, which breaks down the issue: examining retry logic, checking if the customer's plan includes rate limit headers, and considering time-based throttling patterns. The customer receives a step-by-step diagnosis with concrete code fixes. Complex technical questions get resolved in the conversation instead of being escalated to engineering.

Personalized Product Recommendations with Context

A shopper describes their home office setup and asks which monitor fits their needs. Your AI Agent uses DeepSeek-Chat to analyze the requirements, call product catalog functions to check inventory, and reason about compatibility with the described setup. The customer gets a tailored recommendation with justification, not a generic product list. Conversion rates improve because the recommendation feels consultative, not algorithmic.

Multilingual Knowledge Base Queries

A customer writes in Japanese asking about subscription cancellation policies. Your AI Agent sends the message through DeepSeek's Chat Completion API, which understands the query natively, retrieves the relevant policy details via function calling, and responds fluently in Japanese. No translation layer required. International customers receive the same quality of support as your primary language audience.

FAQs

Frequently Asked Questions

What is the difference between deepseek-chat and deepseek-reasoner models?

DeepSeek-Chat is optimized for general conversations, instruction following, and quick responses. DeepSeek-Reasoner excels at complex, multi-step problems requiring chain-of-thought reasoning like math, logic, and technical troubleshooting. Your agent can dynamically select the right model based on the complexity of each customer query.

How does thinking mode work and when should I enable it?

Thinking mode lets the model reason through a problem step by step before producing the final answer. Enable it via the thinking parameter for complex technical questions, calculations, or scenarios requiring logical deduction. The reasoning process happens server-side and the customer sees only the refined final answer.

Can the DeepSeek integration call other tools during a conversation?

Yes. DeepSeek's function calling feature allows the model to identify when external data is needed, specify which tool to call with the correct parameters, and incorporate the results into its response. You can define up to 128 tool functions. The agent orchestrates these calls automatically during the conversation.

What is the Anthropic-compatible endpoint and why would I use it?

DeepSeek offers an API endpoint that accepts requests in the Anthropic Messages format. If your existing systems already use Anthropic's API structure, you can route them through DeepSeek without rewriting integration code. It supports system prompts, tool calling, streaming, and extended thinking in the same familiar format.

Does Tars store the prompts or responses from DeepSeek API calls?

Conversation content is processed through DeepSeek's API during active sessions. Tars logs conversation flows for your review in the dashboard but does not independently store raw API payloads. DeepSeek's data handling policies apply to the API layer. Review their privacy documentation for retention details.

How does DeepSeek pricing work for API calls made by the agent?

DeepSeek charges per token for input and output. Pricing varies by model. The agent can check your current balance using the Get User Balance endpoint before high-volume operations. DeepSeek supports both CNY and USD billing. You manage credits through your DeepSeek platform account.

Can I control the response style with temperature and sampling parameters?

Yes. The temperature parameter (0 to 2) controls randomness. Lower values produce more deterministic responses for factual queries. Top_p adjusts nucleus sampling for diversity. Frequency and presence penalties reduce repetition. Configure these per request to match the conversation context.

What context length does DeepSeek support for long conversations?

DeepSeek models support extended context windows. The max_tokens parameter controls response length. For long conversation threads, the agent manages context by passing relevant message history. The stop parameter lets you define custom sequences to control where generation ends, keeping responses focused and relevant.
