TokenCast: Forecasting Token Consumption During LLM Agent Execution
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- TokenCast predicts token consumption for LLM agent tasks by tracking execution segments and context growth, updating forecasts as runs unfold.
- Why it matters
- Matters for engineers building agentic systems who need to budget API costs and predict resource requirements before or during execution.
- Watch out
- Method tested on specific benchmarks and agent models; generalization to other task types or novel agent architectures remains unclear.
