What it does

RTK is a CLI proxy that reduces Large Language Model (LLM) token consumption by 60-90% on common development commands.

When to use it
  • •When developing applications that rely heavily on LLMs and token usage needs to be optimized
  • •When using LLMs for tasks like code completion, text summarization, or natural language processing
  • •When trying to reduce costs associated with LLM token consumption in development workflows
Ready-to-paste prompt
rtk my-llm-model --prompt 'Summarize the following text: ...'
Heads up: RTK requires a valid LLM API endpoint and credentials configured in the `rtk.yaml` file to function correctly
