Why each one is on the shortlist for deepseek model for writing, what it is genuinely good at, and where we would steer you away from it.
Ranked first here for deepseek model for writing: 89/100 on coding, with the widest margin of anything in this line-up.
DeepSeek's September 10, 2026 release, now its top API model: a natively multimodal, MIT-licensed model with 1M context that DeepSeek says beats its own V4-Pro on coding and agent work — V4-Pro traffic has been routed to it since September 14.
You need long single outputs (32K cap) or independently verified scores before you commit.
DeepSeek's current flagship in practice, since V4-Pro requests now run on it. Cheap and open, with coding claims that still need independent confirmation. A strong pick for self-hosting or budget pipelines with review.

The cost-conscious pick for deepseek model for writing, about 13% less per token than DeepSeek V4.1 Flash than the top choice while holding 93/100 on coding.
DeepSeek's 1.6T-parameter (49B active) MoE flagship with hybrid sparse attention — near-frontier coding and reasoning at roughly a tenth of closed-rival pricing, MIT-licensed open weights.
You need vision input, verified agentic performance, or predictable pricing (surge pricing and an announced increase loom).
Retired in practice: since September 14, 2026 DeepSeek serves V4-Pro API requests with DeepSeek V4.1 Flash. Self-reported numbers flatter it and independent agentic scores land lower, but even discounted it's the most capability per dollar in the directory's upper tier — with MIT-licensed weights.

$0.3/1M input tokens and $1.2/1M output tokens via the API. Context window: 1.048576M tokens. On a moderate month — 10M input and 2M output tokens — that works out to about $5.40, against $1.96 for DeepSeek V4-Flash.
DeepSeek's coding claims are self-reported and not yet independently verified; it trails on hard reasoning by DeepSeek's own account. Price varies by host and by time of day — check the rate you will actually pay. Concretely, avoid it if you need long single outputs (32K cap) or independently verified scores before you commit. If none of that is negotiable, Claude Sonnet 5.5 (Anthropic) is the cross-provider leader at 98/100.
high-volume coding assistance where review catches what the model misses, self-hosted deployments — the weights are on Hugging Face under the MIT licence, and image understanding without a separate vision model. Its 1.048576M-token context window is the practical limit on how much you can hand it in one go.
DeepSeek V4.1 Flash scores 83/100 on writing against 74/100 for DeepSeek V4-Flash, at 2x the input price. That premium is worth it on work where a wrong answer costs real time or money, and hard to justify on high-volume, low-stakes calls. Most teams run both and route by task rather than picking one.
