Flare
Flare is a specialized local inference server designed for NVIDIA SM120/SM121 GPUs, optimized for long-context conversations, coding agents, and repeated tool use. It utilizes a two-part architecture where Python-based 'Ignition' prepares models and a high-performance Rust-based 'Helios' runtime serves them without Python dependencies.
