By 2025, LLM agents are widely deployed in customer support, devops automation, and internal workflows. With improved memory, tools, and reasoning, they can execute multi-step tasks autonomously.

Key improvements

• Better long-term memory systems.
• Tool-use reliability improved dramatically.
• Guardrails and safety filters are now standard.

When to use agents

• Repetitive multi-step workflows.
• Data extraction and cleanup.
• Customer support automation.

Risks

• Over-execution loops if not constrained.
• Requires clear sandboxing.
• Needs strong observability.

Summary

LLM agents in 2025 are production-ready—but must be deployed with monitoring, constraints, and audit logs.
