okay i think this is a much better visualization of what i mean by "log-centric agent architecture"

babyagi has ~200 citations, but 0 papers... i just published my first paper on arXiv 😆
"The Log is the Agent: Event-Sourced Reactive Graphs for Auditable, Forkable Agentic Systems"
arxiv.org/abs/2605.21997
the case for agents that coordinate through persistent replayable state — no conversation loops, no workflows, no A2A — with auditability, forking, and causal lineage built in.
check it out and let me know what you think!

in arxiv paper #2, i tackle the last topic from paper #1: @activegraphai as an architectural affordance for self-improving agents
"Regimes: An Auditable, Held-Out Gated Improvement Loop Demonstrated on LongMemEval with ActiveGraph"
i demonstrate this with a reproducible gated self improvement loop which autonomously shows modest improvement on longmemeval questions
paper: arxiv.org/abs/2606.10241

two things ready to share from this weekend:
📖 learn.activegraph.ai
interactive site teaching activegraph concepts
blog: activegraph.ai/blog/introduc…
💻 AG coder (open source)
reference coding agent on activegraph
GH: github.com/yoheinakajima/ag-…
blog: activegraph.ai/blog/ag-coder
still in progress: deep research agent, bounded self-improvement research, core packs...

Authorship and authority are different events.
Generated code shouldn't automatically become live behavior. It should enter as inert state, pass gates, and only get runtime authority at explicit promotion.

"Self-modification" is treated as binary: either the agent rewrote its code or it didn't.
Under event sourcing, every durable action is weak self-change. The question isn't did it modify itself: it's what kind, and can you fork/diff/promote/replay it.

A task triaging system built over @ActiveGraphAI that assesses all open tasks periodically and helps me with their status updates. In this example, it is suggesting that a task (Blue node) should be marked as done (Orange node) based on a project log entry (Yellow node).

a parallel experiment building a coding agent on top of @activegraphai. you can see everything flattened down to a single event log trace

Our third LongMemEval experiments by adding semantic ingestion to deterministic retrieval.
The hybrid approach improved end-to-end QA accuracy to 87.6% and evidence retrieval to 90.0%, but the QA gain did not reach statistical significance in this run.

[New Technical Blog Post] In our second longmemeval experiment, we introduce semantic ingestion into recall leveraging the ActiveGraph runtime.
We started from a 60.6% baseline and improved to 83.4%/84.8% for flat/agentic retrieval with LLM ingestion.

Building a custom UI to view objects, relations, behaviors, logs in @ActiveGraphAI.
The UI starts with a pack. The pack lists all the objects, relations and behaviors. Selecting an object shows the lifecycle from creation to current state and what behavior triggered a change in its state.

If you are into DAG workflows, n8n and all that, stop what you are doing and look at @ActiveGraphAI. It's a bigger deal than what Claude released with Dynamic Workflows today. Believe me, you won't be disappointed!
It's still a new project but shows a lot of promise. Keen to integrate this into my existing workflows.

"If I had Cofounder three years ago," says @yoheinakajima, "BabyAGI might have been a company."
Our newest case study tracks our most active user, Yohei Nakajima, building @ActiveGraphAI - the event sourced graph runtime for long running agents.

ActiveGraph is not the highest public LongMemEval number. Its narrower position is that it is a low-context, non-generative-ingestion substrate result: 85.6% QA at 2.4k context tokens, with paired statistics, pinned artifacts, and a replayable event-sourced runtime underneath.

Reproducibility:
The benchmark harness is in github.com/yoheinakajima/act…. The repo pins the LongMemEval submodule, Python version, reader settings, judge model, embedding model, lockfile, dataset checksums, per-run manifests, and token counts
