Cost Optimizer Tracks cumulative LLM costs across DAG execution and makes real-time decisions to stay within budget: downgrade models, skip optional nodes, or stop early. --- When to Use ✅ Use for : - Setting and enforcing cost budgets for DAG executions - Real-time cost monitoring during execution - Deciding when to downgrade model tiers mid-execution - Identifying which nodes are most expensive and why - Post-execution cost analysis and optimization recommendations ❌ NOT for : - Choosing which model to use per node (use ) - Provider pricing comparisons (static data, not a skill) - Billing o…
