DeepSeek

Open-source frontier reasoning, via BYOK on OpenRouter.

DeepSeek V4 and V4 Pro are open-source models that punch in the same weight class as Claude Sonnet and GPT-5 on reasoning benchmarks, at a fraction of the price. MoClaw doesn't include DeepSeek in your monthly credits, but you can route every call through your OpenRouter key and pay provider rates directly with no markup.

How it works

3 steps to wire up DeepSeek, no engineering required.

  1. 1

    Top up an OpenRouter balance

    Go to openrouter.ai, add $10 to your account. OpenRouter passes through DeepSeek's pricing — currently around 90% cheaper than Claude Sonnet for the same task.

  2. 2

    Paste your OpenRouter key into MoClaw

    Settings then Models then BYOK then OpenRouter. Stored encrypted at rest, decrypted only at request time.

  3. 3

    Pick DeepSeek V4 or V4 Pro in the model picker

    Switch on a per-chat basis. The rest of MoClaw — skills, browser control, cloud computer, scheduled jobs — keeps working the same.

Try saying

Real prompts you can paste into DeepSeek.

  • › On DeepSeek V4 Pro, walk through this 2,000-line algorithm and find the off-by-one bug.
  • › On DeepSeek V4, summarize these 50 customer interview transcripts into 5 themes.
  • › On DeepSeek V4, classify 10,000 support tickets in batch — I care about cost more than quality.

What actually happens when you send the prompt.

Prompt 01 4 steps

“On DeepSeek V4 Pro, walk through this 2,000-line algorithm and find the off-by-one bug.”

What MoClaw does

  1. 1 Reads the file top-to-bottom in one pass (V4 Pro has a 128K context window).
  2. 2 Builds a data-flow trace through the loop in question.
  3. 3 Flags line 1,847 as the off-by-one: index runs i ≤ n.len, should be i < n.len.
  4. 4 Suggests a 1-line fix and the failing test case that would catch it.
Result

Returns a code review with the bug pinpointed at line 1,847, a 1-line patch, and a Go test that fails before and passes after. Costs about $0.04 on OpenRouter — roughly 4 credits if it had been Claude Sonnet.

FAQ

Quick answers about pricing, privacy, and limits.

Why isn't DeepSeek in the included plan?
OpenRouter is a third-party gateway and DeepSeek is open-source. Bundling it would mean MoClaw eats the variable cost. BYOK keeps you paying provider rates directly with no MoClaw markup.
How does DeepSeek compare to Claude Sonnet on real tasks?
On reasoning benchmarks (MMLU, MATH, HumanEval) V4 Pro is within ~5% of Sonnet 4.6 at roughly 1/10 the cost. On creative writing and complex multi-step agentic work, Claude is still ahead. Try both for your own workload.
Can I use DeepSeek with skills, browser control, cron?
Yes. BYOK only changes the model billing. The MoClaw runtime — skills, browser control, cloud computer, scheduled jobs, file handling — works identically.
What about V4 vs V4 Pro?
V4 is fastest and cheapest, comparable to Haiku in speed. V4 Pro adds reasoning ability, comparable to Sonnet. Both are available on OpenRouter.
