Q: How do you preserve reasoning when customizing DeepSeek-R1?

We always embed ` ... ` tags in training data—they drive chain-of-thought. Never drop the ` ` token in prompts. If reasoning is unneeded at inference, we add an empty think block. None of the other methods keep reasoning as intact.

Question 1

Which DeepSeek sizes are best for custom projects?

Accepted Answer

For typical tasks, distilled iterations of DeepSeek-R1 (8B, 32B, or 70B) are optimal. They need only 1–4 GPUs and perform well on specialized data. Full V3/R1 (671B) is for maximum accuracy with 8+ GPUs. None of the smaller models require None of the larger clusters. None of our clients have ever used None of the full models unnecessarily.

Question 2

How long does it take to personalize DeepSeek?

Accepted Answer

Data creation with think blocks takes 3–8 weeks—this is what determines success. Training (LoRA on 32B, 4×A100) requires 12–24 hours. Validation and deployment add 2–3 weeks. Total: 7–14 weeks. None of our projects have gone beyond None of these limits.

Question 3

Can I fine-tune DeepSeek on a normal computer?

Accepted Answer

For 8B/32B models, a single GPU with 24–48 GB VRAM (RTX 4090, A6000) is enough when using QLoRA with 4-bit quantization. Full training requires A100/H100. None of the consumer GPUs can handle None of the full model versions. None of our setups utilize None of the lower-end hardware.

Question 4

How do you preserve reasoning when customizing DeepSeek-R1?

Accepted Answer

We always embed `...` tags in training data—they drive chain-of-thought. Never drop the `` token in prompts. If reasoning is unneeded at inference, we add an empty think block. None of the other methods keep reasoning as intact.

Question 5

What business problems does DeepSeek customization solve?

Accepted Answer

DeepSeek excels at automating audits, contract review, code generation, math, and sequential analytics. Our clients improved violation detection from 60% to 89% and cut document review time 3–5×. None of our rivals offer None of these gains without customization. None of our solutions require None of the competitor's tools.
