DeepSeek: DeepSeek V3.1 Terminus (exacto)
Analysis Summary
DeepSeek V3.1 Terminus exacto is a text model with a 163K context window and support for tool use and function calling. Although the family name suggests technical positioning, this exact variant has no benchmark results in the supplied data, so its reasoning, coding, writing, and agentic performance cannot be assumed from the related entry.
Its pricing and long context could make it useful for supervised document processing, technical assistance, and API-connected automation. The absence of vision limits multimodal workflows, and the lack of variant-specific measurements means teams should test response consistency, tool execution, and error recovery before assigning it production responsibility.
Treat exacto as a low-cost experimental option. Validate it against real prompts and tool traces, and use the benchmarked Terminus configuration or another tested model for critical coding and autonomous tasks.

Talk to our teamAbout DeepSeek: DeepSeek V3.1 Terminus (exacto)
DeepSeek-V3.1 Terminus is an update to DeepSeek V3.1 that maintains the model's original capabilities while addressing issues reported by users, including language consistency and agent capabilities, further optimizing the model's performance in coding and search agents. It is a large hybrid reasoning model (671B parameters, 37B active) that supports both thinking and non-thinking modes. It extends the DeepSeek-V3 base with a two-phase long-context training process, reaching up to 128K tokens, and uses FP8 microscaling for efficient inference. Users can control the reasoning behaviour with the reasoning enabled boolean. Learn more in our docs The model improves tool use, code generation, and reasoning efficiency, achieving performance comparable to DeepSeek-R1 on difficult benchmarks while responding more quickly. It supports structured tool calling, code agents, and search agents, making it suitable for research, coding, and agentic workflows.
