Vareon Duplex is your AI model and an ACI model, working as one.
The combination is the product: runtime intelligence for your AI and your agents, for one person or the whole enterprise. Together they learn, plan, simulate, decide and act at runtime: they learn from every result, choose the route, plan the steps, simulate each one, act within your rules, acquire skills and carry decisions and learning across sessions, agents, apps and models. What it builds is yours.
A persistent learning runtime for AI agents.
Duplex makes AI agents remember, learn, plan, simulate, decide, improve, obey and continue, across sessions and models. It is not just a vector database, a memory plugin, a prompt manager, an MCP server, a workflow engine, a policy gateway or a fine-tuning system. It combines parts of all of them into one runtime that learns.

Built on ACI.
Duplex is built on ACI, Adaptive Continual Intelligence: a new category of intelligence that learns, plans, simulates, decides and acts at runtime, in tandem with AI models. With ACI, your AI learns on the spot, plans, simulates, decides and acts on what it learned, keeps up with every change, gets faster and cheaper with use, and what it learns is yours.
Duplex
The product you useDuplex works inside the assistants your team uses and inside the agents your company builds. It starts informed, decides the route, acts within your rules and carries its decisions, its learning and your context forward.
- Inside your assistants
- Inside your own agents
- Within your rules
- In the placement you choose
ACI
The intelligence in DuplexIt learns, plans, simulates, decides and acts while the work happens, leaves your model’s weights alone, and everything it learns belongs to you.
- Learns from every result
- Acts within your rules
- Keeps up with every change
- Yours, wherever you work
What Duplex does for your AI.
24 ways it makes your AI better. Watch them play, or press any one.
Every conversation becomes intelligence your company owns.
The answers, fixes and decisions your AI works out stay with your company, and every task makes the next one better.
See it at work →Step 1 of 4: Confirmed
Confirm a result, and Duplex learns it on the spot.
Continual learning is the holy grail of AI.
Duplex is built on ACI, Adaptive Continual Intelligence: Vareon’s proprietary algorithms and architecture for intelligence that learns, plans, simulates, decides and acts continually at runtime. It learns from every confirmed result, still knows what it learned before, and lets you change any piece of it: plasticity, stability and editability, all at once.
Duplex learns from every confirmed result, and builds on it.
Step 1 of 5: It learns
Intelligence, not retrieval.
RAG, vector databases, knowledge graphs, caches and memory store what happened and find what looks like it. Duplex learns: it understands the pattern behind each result, compresses it into what generalises, predicts what comes next, and acts on it.
When a request only looks familiar, retrieval returns the nearest match. Duplex understands the pattern, and sees the difference.
Step 1 of 5: A look-alike
A look-alike
Retrieval Returns what looks similar, right or wrong.
Duplex Understands the pattern, and sees the difference.
New words
Retrieval Finds nothing close enough.
Duplex Learned the pattern, so it still knows.
A rule changes
Retrieval Serves the old answer until someone edits the store.
Duplex Follows the new rule from the next request.
With use
Retrieval Only grows, and every search gets bigger.
Duplex Compresses what it learned, and gets faster and cheaper.
What comes next
Retrieval Waits to be asked.
Duplex Predicts the next step, and acts on it within your rules.
- RAG Finds passages that look like the question
- Vector databases Find close matches
- Knowledge graphs Find what someone linked
- Caches Return what was asked before
- Memory Recalls what was saved
Duplex can use every one of them as a tool, and it learns from what they return.
For many tasks, you no longer need to fine-tune.
Teams fine-tune for their knowledge, their way of working and better results. Duplex brings all three from your own work, and your model stays as it is.
- Your terms and knowledge, learned from results your team confirms
- Your format, tone and rules, on every answer
- Better results: it beat tuned fine-tuning in 6 / 6 tests*
- Lower cost: 90.3% fewer model calls*
- A change in your work, live by the next request
- 0 retraining when you change models*
- Any lesson taken back on its own
- No training runs, and no GPU of its own
A fine-tune rewrites the weights, one model and one training run at a time.
Step 1 of 4: A training run
It learns, plans, simulates, decides and acts, at runtime.
An ACI model beside your AI gives it what it lacks while the work happens. Follow one job through everything Duplex does.
Step 1 of 5: Learns
A job arrives that needs a skill Duplex does not have yet, so it learns it where it is safe to try, and checks it before the job relies on it.

The work it changes.
Each kind of work, and what changes once Duplex learns it.
Step 1 of 6: Coding
Coding and desktop assistants: Your project’s conventions, applied in every session.

Your project’s conventions, applied in every session.
Duplex applies your project’s conventions and confirmed fixes in new files and new sessions, inside Claude, Codex, Cursor and Hermes.
See the plugins →Support and operations agents
A policy change takes effect on the next request.
Returns, routing and exceptions are answered in milliseconds, and a changed policy applies on the next request.
See the agent benchmark →Enterprise workflow automation
Agents that know how your systems respond.
Duplex learns what each action changes and plans the route. It beat three frontier models at predicting system changes.
See the workflow benchmark →High-volume AI products
90% fewer model calls, with accuracy up from 59.8% to 94.6%.*
Duplex answers the decisions it has learned, in milliseconds, and your AI reasons through the rest.
