@AnthropicAI The takeaway: frontier coding models are beginning to compete on delivered engineering economics, not capability alone.
Evaluate task completion, review time, regressions and total cost on your own work before switching.

@AnthropicAI's new Claude Opus 5.5 is a notable shift for coding agents:
• Better reported coding results
• 40% lower typical task cost
• 30%+ faster output
• Much cheaper cache reads
The interesting part isn’t another benchmark win. It’s the economics.
@AnthropicAI Opus 5.5 also adds stronger safeguards.
Certain high-risk cyber, biology and frontier-AI requests may be routed to less capable models.
Anthropic reports 85% fewer containment-boundary violations in internal tests.
Useful progress—but independent testing still matters.
