About DeepSeek V3

DeepSeek V3 is a 671B-parameter mixture-of-experts model from the Hangzhou lab that made headlines for reaching GPT-4o-level quality on most public benchmarks at roughly 1/30th the cost. Open weights, strong at code and reasoning.

What it's good at

1

Frontier-quality reasoning at budget prices

2

Excellent at code — benchmarks near Claude 3.5 Sonnet

3

Open weights (self-host if you want)

4

64k context

Frequently asked — DeepSeek V3

What is DeepSeek V3?

DeepSeek V3 is a 671-billion-parameter mixture-of-experts model from DeepSeek (a Hangzhou-based lab). Released December 2024, it benchmarks close to GPT-4o and Claude 3.5 Sonnet at roughly 1/30th the training cost.

Is DeepSeek really as good as GPT-4o?

On most public benchmarks, yes — it's within a few percentage points on code, math, and reasoning. On creative writing and some edge cases, GPT-4o is still ahead. Try both on the same prompt.

Are the weights open source?

Yes — DeepSeek V3's weights are on HuggingFace under a custom licence that allows commercial use with attribution. You can self-host if you have the compute.

How cheap is DeepSeek V3 per message?

Often under 1,000 credits per message (compare GPT-4o at 3,750–9,200). Some of the best quality-per-credit on the platform.

Is my data safe with DeepSeek?

We route through upstream hosts, not DeepSeek directly. Check the specific host's terms in the model details — some US-based hosts explicitly prohibit cross-border training.

What's the context window?

64,000 tokens. Smaller than Claude (200k) or Gemini (1M), but still comfortable for most tasks.

Is DeepSeek V3 multimodal?

No — text-only. DeepSeek has separate vision models; our picker lists them if you need image input.

How does it compare to DeepSeek R1?

R1 is the reasoning-focused variant with visible chain-of-thought, optimised for math/logic. V3 is the general-purpose chat variant. Both are in our picker.

Can I call DeepSeek V3 from the API?

Yes. Model slug: deepseek/deepseek-chat. OpenAI-compatible SDK works with base_url=https://api.faceb.ai/v1.

Why is it so much cheaper?

Mixture-of-experts architecture activates only a subset of the 671B parameters per token (~37B active), plus aggressive training optimisations. Both factors drop inference cost.

Is DeepSeek V3 good for English / non-Chinese tasks?

Yes — it was trained on a substantial multilingual corpus. English output quality is comparable to the big Western labs.

Will DeepSeek V4 show up when released?

As soon as our upstream aggregator adds it, yes — automatically.
