R1 0528

DeepSeek's 671-billion parameter reasoning model with fully transparent chain-of-thought reasoning tokens and a 163k token context window.

Strengths

Delivers reasoning-focused performance comparable to o1 while making its reasoning process fully visible through open reasoning tokens.

Best for

Complex reasoning tasks, multi-step problem solving, and applications where transparent model reasoning is valuable or required.

Limitations

Large parameter count means inference is computationally expensive; reasoning token expansion can significantly increase context usage on complex queries.
