Context · A

The first publicly available frontier reasoning model. Trained to spend extra inference compute on a "private chain of thought" before answering, setting the template the open community would chase with R1.

Context · B

An incremental post-training refresh of the 70B class that approached 405B-class quality on several benchmarks without the deployment cost. The last dense Llama before Llama 4 went MoE.
