DeepSeek chat model for instruction following, coding, and analysis
DeepSeek V3.1 Terminus is offered by 12 providers on this page. Public prices are shown for 11 of them. Its reference price is $0.27 per 1M input tokens and $1.00 per 1M output tokens.
Artificial Analysis rates it 14.8 on the Intelligence Index, with 43.5 for coding and 6.8 for agentic tasks. Against its lowest blended price of $0.362 per 1M, that is roughly 41 index points per dollar, which is the value ratio the leaderboards rank on.
The context window is 163,840 tokens at the reference host, but hosts report different limits, from 128,000 to 164,000, so the usable window depends on the provider you pick. It supports reasoning, tool use, and structured output. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use. Its training knowledge cuts off at 2025-03-31.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

2 / 12 providers expose no reasoning control (reasoning_options: []).
Individual evaluations run by Artificial Analysis, on the same reasoning tier as the intelligence score above. Each benchmark has its own task set and harness, so rows are not comparable with one another. The Intelligence Index above draws on a different, newer set of evaluations.
