Frozen BFCL Routing-Pressure V6 Replication
This page records the first successful scored run of BFCL routing-pressure v6, a larger untouched replication of the frozen v5 pilot.
Headline result
On 48 fresh BFCL V4 multiple tasks with zero overlap with v5, AgentWeave was the only strategy to achieve any native BFCL successes:
| Strategy | Native BFCL success | Mean tools shown | Input tokens | Mean latency |
|---|---|---|---|---|
| Single-agent / all tools | 0/48 = 0.0% | 16.00 | 124,821 | 55.92 s |
| Random top-8 | 0/48 = 0.0% | 8.00 | 69,790 | 30.56 s |
| Semantic top-8 | 0/48 = 0.0% | 8.00 | 70,271 | 35.87 s |
| AgentWeave | 6/48 = 12.5% | 4.77 | 47,805 | 27.43 s |
AgentWeave's paired native-success difference versus each matched baseline was +12.5 percentage points, with a 10,000-resample paired bootstrap 95% CI of +4.17 to +22.92 pp and exact McNemar p = 0.03125.
Against the all-tools baseline, AgentWeave used approximately 70.18% fewer visible tools, 61.70% fewer input tokens, and 50.95% lower mean local-model latency.
Replication relationship to v5
The frozen v5 pilot used 12 tasks and produced AgentWeave 2/12 = 16.67% versus 0/12 for all three matched baselines, but with McNemar p = 0.5 because the sample was small.
V6 kept the v5 model, routing budgets, baselines, 16-tool pressure, generation settings, and native BFCL evaluation unchanged. It used a new content-blind sample and explicitly excluded all 12 frozen v5 task IDs. The resulting 6/48 = 12.5% vs 0/48 outcome therefore serves as a larger untouched replication of the directional v5 finding.
Routing diagnostics
| Strategy | Mean original-candidate recall | All original candidates retained |
|---|---|---|
| Single-agent | 100.00% | 100.00% |
| Random top-8 | 48.44% | 10.42% |
| Semantic top-8 | 86.81% | 66.67% |
| AgentWeave | 76.91% | 54.17% |
Semantic top-8 retained more original BFCL candidates than AgentWeave, yet still scored 0/48. AgentWeave achieved 6/48 while exposing fewer tools, so the native-success result cannot be explained by candidate retention alone.

Evidence boundary
This is a BFCL-derived routing-pressure replication, not an official full BFCL leaderboard score. The experiment preserves untouched BFCL questions and native BFCL evaluation while deterministically augmenting the model-visible tool context. It is keyless, local, single-turn, and uses $0 external API spend.
The v6 result is frozen. Any tuning or further replication must use a new study ID and a fresh untouched sample.
