Router (Website)
Router claims to reduce AI inference costs by 40% by dynamically matching incoming requests to the most cost-efficient model that meets performance requirements.
What: Router is an AI infrastructure tool that balances inference workloads by monitoring latency and failure rates to route requests to the lowest-cost model capable of handling the task.
Why it matters: This represents a move toward 'model-agnostic' serving, where infrastructure platforms prioritize resource optimization rather than being locked into a single model provider.

- LoRA (Low-Rank Adaptation): A technique for fine-tuning large models by freezing most original parameters and training only a small, modular set of weights, making adaptation significantly faster and less memory-intensive.

PorTAL: Portable Task Adaptation for LoRA
Learn a task adaptation once in a base-agnostic form, then port it to new frozen models by refitting only a thin per-base alignment — recovering ~98% of per-task LoRA's lift on an unseen model within the same family and ~94% across families.
