Llama 3.1 405B Instruct Turbo
Llama 3.1 405B Instruct Turbo is Meta's largest publicly released model — a 405-billion-parameter instruction-tuned checkpoint from the Llama 3.1 generation, with Turbo optimizations applied for improved inference throughput. At this scale it approaches the performance envelope of leading closed-source models on complex language tasks while remaining accessible as an open-weight model.
The Turbo designation indicates additional inference-side optimization to reduce the latency penalty typically associated with models at this parameter count, making it more viable for applications that previously would have considered this scale impractical. It excels at complex reasoning, nuanced writing, and challenging code generation.
