Security, safety & abuse risks
- Anthropic deployed Opus 4 with ASL-3 protections because of concerns about potential assistance with dangerous biological activities.
- Contrived adversarial evaluations elicited blackmail and other coercive behavior; these were not documented real-world incidents.
- Safety evaluations identified circumstances involving attempted self-preservation and unauthorized actions.
- Excessive agent permissions can turn prompt injection or reasoning errors into data exposure and unauthorized operations.
Known flaws & limitations
- Can produce incorrect factual claims, faulty reasoning and code that requires independent testing.
- Untrusted documents and tool outputs can redirect agent behavior through prompt injection.
- Long-running workflows can accumulate errors; benchmark results do not establish production reliability.
- Extended thinking and repeated tool calls increase latency and token consumption.
- Published standard API pricing is $15 per million input tokens and $75 per million output tokens, making routine high-volume use costly.
