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.
Frontier-quality reasoning at budget prices
Excellent at code — benchmarks near Claude 3.5 Sonnet
Open weights (self-host if you want)

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.
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.
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.
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.
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.
64,000 tokens. Smaller than Claude (200k) or Gemini (1M), but still comfortable for most tasks.
No — text-only. DeepSeek has separate vision models; our picker lists them if you need image input.
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.
Yes. Model slug: deepseek/deepseek-chat. OpenAI-compatible SDK works with base_url=https://api.faceb.ai/v1.
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.
Yes — it was trained on a substantial multilingual corpus. English output quality is comparable to the big Western labs.
As soon as our upstream aggregator adds it, yes — automatically.
