The best text-only setup glm-5.2 + mm outperformed gemini-3.5-flash, the top vision model, by 5.4 points (6.5%). It was also:
• 1.5x faster (100s vs 150s mean per task) • the only setup with zero timeouts (46/46 completed; gemini timed out 4x on bulk-image and long-video tasks) • the only setup stable across runs (88.5 / 88.4) • top on video (100.0), image (91.7), and PDF (90.0) tasks
The trade-offs: the toolkit consumed 3.3x more tokens (4.25M vs 1.28M), and lost on audio (85.6 vs 71.3).
On completed tasks alone the two are nearly identical (91.0 vs 88.4): the toolkit's edge is efficient extraction that keeps long media tasks inside the time budget.
