A developer shared a common pitfall in multi-agent LLM workflows where fallback mechanisms inadvertently escalate to more expensive models like Claude Opus, despite being configured for cheaper options like Haiku. This oversight can lead to significant unexpected costs, with Opus calls accounting for 92% of the bill in one example. The author introduces "tokenjam", a tool designed to provide visibility into which specific model handled each API call, enabling developers to track costs accurately and set budget alerts. AI
