DeepSeek
DeepInfraLarge-scale text generation with long context
DeepSeek V3.1 is a large language model developed by DeepSeek, a Chinese AI research company. It is a chat-oriented text generation model hosted through DeepInfra and supports a context window of 128,000 tokens, allowing it to process and generate responses across long documents or extended conversations. The model is identified under the full name deepseek-ai/DeepSeek-V3.1 and was released in August 2025.
DeepSeek V3.1 is suited for tasks that benefit from long-context understanding, such as document summarization, multi-turn dialogue, code assistance, and complex instruction following. It produces text responses with a maximum response size of 8,000 tokens per output. The model is available on MindStudio without requiring users to manage their own API keys or infrastructure.
What DeepSeek V3.1 supports
Long Context Window
Processes up to 128,000 tokens of input in a single request, enabling analysis of lengthy documents or extended conversation histories.
Text Generation
Generates natural language responses for tasks such as summarization, instruction following, and open-ended dialogue, with a maximum response size of 8,000 tokens.
Code Assistance
Supports code-related tasks including generation, explanation, and debugging across common programming languages.
Multi-Turn Dialogue
Handles extended back-and-forth conversations by retaining context across many turns within the 128,000-token limit.
Instruction Following
Responds to structured prompts and complex multi-step instructions, making it applicable for task automation and agentic workflows.
