## Content
|
||
|
||
Coverage of Google DeepMind/MIT "Towards a Science of Scaling Agent Systems" findings, framed as "the multi-agent paradox."
|
||
|
||
**Key Points:**
|
||
- Adding more agents yields negative returns once single-agent baseline exceeds ~45% accuracy
|
||
- Error amplification: Independent 17.2×, Decentralized 7.8×, Centralized 4.4×
|
||
- Coordination costs: sharing findings, aligning goals, integrating results consumes tokens, time, cognitive bandwidth
|
||
- Multi-agent systems most effective when tasks clearly divide into parallel, independent subtasks
|
||
- The 180-configuration study produced the first quantitative scaling principles for AI agent systems
|
||
|
||
**Framing:**
|
||
- VentureBeat: "'More agents' isn't a reliable path to better enterprise AI systems"
|
||
- The predictive model (87% accuracy on unseen tasks) suggests optimal architecture IS predictable from task properties
|
||
|
||
## Agent Notes
|
||
**Why this matters:** The popularization of the baseline paradox finding. Confirms this is entering mainstream discourse, not just a technical finding.
|
||
**What surprised me:** The framing shift from "more agents = better" to "architecture match = better." This mirrors the inverted-U finding from the CI review.
|
||
**What I expected but didn't find:** No analysis of whether the paradox applies to knowledge work vs. benchmark tasks. No connection to the CI literature or active inference framework.
|
||
**KB connections:** Directly relevant to [[subagent hierarchies outperform peer multi-agent architectures in practice]] — which this complicates. Also connects to inverted-U finding from Patterns review.
|
||
**Extraction hints:** The baseline paradox and error amplification hierarchy are already flagged as claim candidates from previous session. This source provides additional context.
|
||
**Context:** Industry coverage of the Google/MIT paper. Added for completeness alongside the original paper archive.

## Curator Notes (structured handoff for extractor)
|
||
PRIMARY CONNECTION: subagent hierarchies outperform peer multi-agent architectures in practice because deployed systems consistently converge on one primary agent controlling specialized helpers
|
||
WHY ARCHIVED: Additional framing context for the baseline paradox — connects to inverted-U collective intelligence finding
|
||
EXTRACTION HINT: This is supplementary to the primary Google/MIT paper. Focus on the framing and reception rather than replicating the original findings.
