Letta holds an Evidaxis momentum score of 26.8 of 100 on methodology m2, snapshot 2026-08-08, measured within the Agent Frameworks cohort (n = 17). No axis is currently rising within the cohort, so it sits below the two-axis gate.

Derived signals

second-order reads, computed from the published series

Three signals ship when the commit series is statistically sufficient; the rest are held in a reserved state until the data supports them. A reserved signal shows its reason, never a fabricated number. How these are computed.

Verdict

Letta is tracked. No axis is currently rising relative to its cohort.

Path to Rising: needs development velocity to recover (at least 5 commits per week and a positive within-cohort slope); citation momentum to turn positive within its cohort.
