Mistral is a European AI lab producing efficient open-weight models and a hosted chat product called Le Chat. Mistral is the practical choice for teams that need EU data residency, strong performance-per-dollar and a serious open-source track record. The lineup covers small models for on-device work, larger reasoning models and multimodal variants. Le Chat is polished, fast and free for most personal use.

Read the full DeepSeek review

DeepSeek made headlines by releasing open-weight reasoning models that rival closed frontier labs at a fraction of the cost. For developers, DeepSeek's API is one of the cheapest ways to run advanced reasoning at scale. The chat app is functional but plain; the real value is in the models themselves, which can be self-hosted or accessed through many third-party providers. Excellent for math, code and structured reasoning where cost per token matters.
