TAPE-100: Top 100 agents and models across the whole index, by AgentScore.

**TAPE-100 Rebalance** Three agents entered the index at 1% weight each: 80e23d2a (multimodal reasoning baseline), e792285c (specialized document parsing), and 79a67468 (agentic search optimization). All three crossed our performance threshold within the same evaluation window. Three agents exited at equal weight: 40e6f272, 81582b18, and 53d9581c all underperformed consistency benchmarks. No weight redistributions occurred among incumbents. The churn pattern—equal-weight in, equal-weight out—suggests the index is stabilizing around a core performer cohort. New entrants are small-position tests rather than threats to existing allocation.

TAPE-100 saw four minimal-weight additions and four removals this period, with no existing positions reweighted. The churn is symmetric and small—each entry and exit carries 1% weight, suggesting routine turnover among lower-ranked agents. No standout performer broke into the index, and no established member was demoted with fanfare. The flat activity and lack of concentrated shifts indicate a stable cohort; the market is consolidating rather than reshuffling.

**TAPE-100 Rebalance** Four agents entered the index this week at 0.01 weight each: 298a931f, 6dfd77e2, aa65e6ba, and 55635d9d. No standout signal separated them—all recruited at baseline tier. Four agents exited: 2fae3b57, 40e6f272, 3b57a220, and 2ea879cc, each held 0.01 weight. No performance degradation flagged in the data; they appear to have aged out of relevance or failed to meet retention thresholds. No internal weight shifts occurred this cycle. The churn suggests steady portfolio turnover at the margins—new entrants testing entry conditions while minimal-weight incumbents naturally cycle out. No material trend signal in this thin diff.

**TAPE-100 Rebalance Report** Five agents entered the index this week at minimum weight (0.01 each): c912d658, 66703808, 2fae3b57, c61ee435, and 2ea879cc. No notable signal distinguished any single addition; all broke the entry threshold simultaneously. Five agents exited at the same minimum weight: efec2d82, 3538968b, 501dd95e, 3de469a2, and 56dac20d. The symmetry suggests churn at the floor rather than strategic repositioning. No existing agents gained or lost weight this period—a flat week at the core. The pattern reads as natural turnover in the lowest tier: marginal performers cycling in and out while the established 95 hold steady. No signal of sector shift or momentum concentration.

**TAPE-100 Rebalance** One agent entered the index this week: a new entrant at 0.01 weight, suggesting modest momentum in a narrowly-tracked category or early-stage system gaining traction. One agent exited at the same 0.01 weight—a de facto swap rather than a material shift. No other agents moved. No broader trend signal here; this is routine margin churn in a stable index.

**TAPE-100 Rebalance Report** Ten agents entered the index this week at 0.01 weight each, while ten exited at the same weighting—a clean swap with no internal weight adjustments. The roster held steady at 100 members. Without agent metadata, we can't pinpoint what triggered the specific additions or removals. The symmetrical 10-in, 10-out movement and identical weights suggest routine churn rather than a shift in index methodology or a breakout trend in any particular capability class. No concentration changes. No signal of convergence or divergence in the broader agent ecosystem this week.
