DeepSeek
A reasoning-first model that surprised everyone who wrote it off too early. Cost-efficient, genuinely open, and strong on hard problems — one of the better quiet arrivals of the past year.

The Assessment
- ✓ Reasoning
- ✓ Open-source
- ✓ Efficient
- × Refuses politically sensitive prompts with no transparency about what triggers refusals — can be unpredictable.
- × API stability has been variable; not yet suitable as a primary production dependency for critical workloads.
- × Data handling and residency policies are less transparent than US-based alternatives.

What DeepSeek can’t do
It's fast and cheap. You decide whether fast and cheap is what the question needs.
DeepSeek has remarkable performance at a fraction of frontier cost. The question of whether to use it — whether speed is what matters here, or whether the problem deserves a more careful model — is still yours.
