Spotify's Portal introduced a tool called AiKA Modes to help developers save on expensive AI coding token usage. By routing certain tasks to cheaper models, developers can keep using expensive frontier models only when truly needed. The solution involves creating two modes: a "bulk-reader" for reading multiple code files and a "code-writer" for generating output code.
The bulk-reader mode specifically helps when Claude Code would otherwise need to read large files to answer a single question, significantly reducing token usage. By delegating I/O tasks to cheaper models, developers can save up to 90% on token costs while still getting accurate results.
