Anthropic says three Claude models each wrote routes to four targets in 26 to 84 minutes. Professors reviewed the plans blind; none has been tested in a lab.

Why it matters #
Route planning consumes expert time before a chemist runs a single reaction, so a model that can draft a credible route from one structure image could change how laboratories allocate graduate-student and postdoc hours. Anthropic's blind design using unpublished targets addresses the recall problem that weakens many chemistry demonstrations.
Anthropic said on November 9th that three Claude models each produced a complete synthetic route to four targets from unpublished syntheses after receiving one image of each target, with no internet, literature or reaction-database access and local code as the only tool. Claude (@claudeai) described the work in a thread on X, and Anthropic published the fuller account in a [report by David…
