Trinity Large (400B)

Overview

Trinity Large (Preview) is a 400B-parameter (13B active) sparse mixture-of-experts language model, engineered to scale model capacity while maintaining inference efficiency over long contexts, with strong performance in reasoning-heavy workloads including math, coding-related tasks, and multi-step agent workflows.

Key Features

• Sparse mixture-of-experts architecture: Uses an extremely sparse MoE design with 400B total parameters and 13B activated per token. Sparse expert routing constrains per-token activation, enabling efficient inference at scale.

• Long-context training and utilization: Trained at 256K sequence length with support for 512K inference (hosted at 128k), using architecture and training procedures designed to operate effectively over long inputs and extended multi-turn interactions over large inputs.

• High throughput efficiency: Designed with inference-time efficiency as a primary objective, leveraging both extreme sparsity and optimized attention mechanisms to achieve strong throughput on modern accelerator hardware.
