Speed. And separately, instruction fine-tuning an LLM for a specialized task like function calling or guardrails == better performance. Even Anthropic and other model providers suggest you separate tasks for LLMs to improve overall user experience

We happen to take those tasks that are non-business or domain specific related and trained our models to offer SOTA performance for 1/10th the cost and 10x the speed. For e.g. Arch-Function can process 5k/tokens per sec
