Tool-using & reasoning systems

学習方法

Tool demonstrations, supervised reasoning traces, outcome or process feedback, reinforcement learning, and verifiable tasks can shape behavior. Runtime scaffolding remains necessary even when the base model is post-trained for tool use.

推論の実行方法

The controller may spend multiple model calls and tool operations on one task. Budgets, deadlines, idempotency, approval gates, sandboxing, and explicit terminal conditions bound the loop.

強み

• •Access to current data, calculators, code, and enterprise systems
• •Can decompose, inspect, and verify multi-step work
• •Typed interfaces make capabilities and permissions explicit

トレードオフ

• •More latency, cost, and failure modes than one model call
• •Tool output and retrieved web content are untrusted inputs
• •Loops, repeated side effects, and excess authority create operational risk

適する場合

• The task requires actions or information outside model weights
• Intermediate results can be validated
• Permissions, budgets, retries, and human approval are explicit

避ける・再検討する場合

• One deterministic API call solves the task
• The agent would receive broad credentials without containment
• There is no evaluation for loops, tool errors, or unsafe actions
