Editor's note
GLM-5.1 is the GLM tool to watch for long autonomous coding runs. Z.ai's own benchmark claims are strong, but we keep the tool at solid until independent score rows are imported into VerdictPal's ledger.
Benchmark placements

Where GLM-5.1 places on each public benchmark source that publishes a row. Rank counts every model with a latest row in the same test — not a universal quality score.
