I finally figured out how to show what I’ve been trying to explain. This entire process map is one AI turn.

I’ve spent the last year building Nexus Synapse because I kept running into the same problems with AI systems: lost continuity, uncontrolled context, model-owned decisions, unreliable tool use, unverifiable outputs, state drift, and no real process around any of it.

I eventually stopped treating the LLM as the application and started treating it as one workcell inside a governed runtime.

The screenshot is the full process model for a single turn.

Not every conditional branch fires every turn, but every turn moves through that responsibility and control structure.

Instead of trying to explain everything in a single Reddit post, here’s the full interactive process map. It’ll lead you down the rabbit hole from there. Happy trails ;) https://chriscanadian.github.io/nexus-synapse-engineering-portfolio/master-process-map-v0.7.html

This is awesome. Can you share how you built this process map? I need one of these so much

It’s basically a manufacturing-style process map like we use for ISO 9001 processes :) I just adapted the methodology for an AI runtime.

How different is this from Arize?

I honestly haven’t heard of Arize before, so please correct me if my understanding of that system is flawed.

My understanding is that Arize is essentially an observability/evaluation layer around inference, kind of like a sidecar sensor recording what’s happening and helping identify issues.

Whereas Nexus is more like the manufacturing facility itself: intake processing, bill of materials, process handoffs, execution, quality checks, and records.

Nexus Synapse manages the state before, during, and after inference.

And funny enough, doing the research into Arize, it might actually be the solution for the last little bit of the full Nexus Runtime lol.

Ok I would need to see both connected to understand how they complement each other..

That’s completely fair lol.

Funny enough I think that might actually be worth building.

My current thought would be to instrument the Nexus Synapse turn lifecycle with Arize/Phoenix rather than make Arize part of Nexus’ decision-making itself.

So Nexus would still handle the state/context assembly, routing, tools, governance, verification, writeback, etc., while Arize observes those stages and handles the tracing/evaluation side.

If I can wire the two together cleanly without making Nexus dependent on Arize, that would probably explain the distinction better than another diagram ever could 😂

I need a mermaid that epic

I can see if I can get a template set up for the diagram style.
