CursorBench 4.0

Source: Anthropic (reviewed publisher results)
Version: 4.0
Measurement date: 2026-09-22
Metric: % · Higher is better
Evaluation scope: Vendor-reported in Anthropic's Claude Opus 5.5 launch table; adaptive thinking at max effort unless noted; evaluated with production safeguards on, and where they intervened, cybersecurity tasks fell back to Claude Opus 4.8 and biology/frontier-LLM tasks to Claude Opus 5 (Anthropic says this likely lowers scores); Cursor's internal suite of tasks from real Cursor sessions; dated to the announcement

Positions are withheld because at least one result lacks explicit independent provenance or a documented evaluation scope. Missing metadata is shown as unreported; matching imported metadata is not independent verification of the protocol.
