Together Compiler: Continual Compilation for AI inference

Together AI introduces Together Compiler (TKCC), a continual optimization loop that uses high-throughput agents to generate inference-engine optimizations, built on "persistent engines" that hot-reload candidate forward passes without restarts and a two-tier engine design balancing measurement throughput against fidelity. TKCC reports up to 2.6x higher TPS across frontier open-source models in under 24 hours, state-of-the-art low-latency results on SemiAnalysis' InferenceX benchmark (1111 TPS on MiniMax M3.1-Flash, 1205 TPS on DeepSeek v4.1-Flash), and 1.7x over open-source megakernels on Llama 1B at batch size 1, enabled by 252x higher experiment throughput than baseline agentic systems. The post also says TKCC generalizes to weather modeling, PDE, time-series, and biology workloads, and is serving trillions of tokens today.
