Work you repeat
Teach it by showing an input and the output you expect. After one explicit example, it can repeat that transformation whenever the same input appears again.
Recently, TypeSafe AI introduced Jev and its System One role in multi-model agent design, opening up a different way to think about how agents work. Today, we want to introduce you to Conceiver, a System Two counterpart to Jev. Conceiver learns from experience and brings what it knows to the task at hand. It can predict intermediate steps or supply relevant information, backed by evidence you can inspect. When it cannot support an answer, it abstains.
The wrapper, included in the Developer plan and above, learns from your agent’s requests and tool calls. After observing a request handled the same way twice, it can recognize a matching request and execute the learned tool call directly, bypassing the LLM API call and saving the tokens you would have spent.
Reflexive models like Jev give you a fast response. Conceiver handles the other half. It works with your LLM, recalls evidence from what you've done before, weighs that evidence, and records where every decision came from. It learns from your examples and from what happens when it acts, so it gets better at your work over time. It is not an LLM. It has no weights and doesn't use backpropagation, and it isn't meant to replace your LLM.
Teach it by showing an input and the output you expect. After one explicit example, it can repeat that transformation whenever the same input appears again.
You can teach it data transformations by showing it unorganized input and the organized output you expect. For example, it can learn to sort and relabel a large, messy file system into organized data sources.
If you run agents in a harness, the agent wrapper lets them learn from what they've already done. When it recognizes a supported step, it may be able to handle it without calling the agent's LLM.
If it has enough evidence, you get an answer. If it doesn't, you get UNRESOLVED together with the relevant evidence it has. Your application can use that evidence for the next decision, such as passing it to an agent's LLM or a person. Conceiver won't make up an answer to fill the gap.
/finance/vendors/acme/Comes with the evidence it usedEvery decision comes with a short Markdown note you can read. It shows you where the answer came from, which examples backed it up, and which examples pointed the other way. That full record is what we mean when we say the provenance is lossless.
A first observation supports a hypothesis. A second independent example establishes confidence in the reusable pattern. A third raises it to high confidence. Conceiver reports these distinctions through evidence levels, not probability percentages.
One supporting example.
Two independent supporting examples.
Three or more independent supporting examples.
Contradictions lower its confidence. A multi-step answer is only as strong as its least-supported step. When answers disagree, Conceiver abstains instead of choosing one and provides the available evidence for downstream decision-making. The API returns ANSWER or UNRESOLVED with the evidence level, so you choose how much evidence you need before you act.
Everything you teach is saved to your training sequence. You can teach that sequence to a new Conceiver in seconds, giving it the same capabilities it had when you left off. Releasing an instance clears its working context, not the saved sequence.
We ran 50 Conceivers at once against Stockfish at level 0. As they played, they all contributed what they learned to one shared knowledge store. The demonstration used hand-tailored chess rules that the base Conceiver does not include. You can download the separately loaded research starter model built from the initial games. It does not contain the later 1,000-game match records.
Each one added what it learned to the shared knowledge store.
Every game was against Stockfish at level 0.
We started them with about 400 games, and we taught them the legal moves for every piece.
We used no GPU, no LLM inference and no LLM API calls.
Conceiver starts with a Unicode lexicon. You teach it the vocabulary and transformations it needs for your workflows. All prices are in US dollars.
Conceiver already knows Unicode characters and a small vocabulary. We kept its vocabulary sparse, so its own words won't clash with your workflow or count as evidence against it. You can teach it how to change natural language and how to handle structures nested inside other structures. Support for raw JSON syntax is in active development.

Usage comes from one shared credit pool. A standard prediction or retrieval costs 1 credit. A memory-enabled query that uses contextual evidence and can recall full episodes costs 2 credits. Teaching costs 5 credits. You can prepay for credits or choose a workspace plan for storage and additional features.
We recommend adding storage before you use episodic memory. Without storage, your Conceiver instance and its episodic memories are ephemeral and disappear when that instance retires. With storage, its memories and learned capabilities are saved as an artifact that you can load into a fresh session.
$0 a month. You don't get storage on this plan, so upgrade to Developer or Pro to keep what you teach.
$29 a month or $290 a year. You get 2 GB of storage and the agent wrapper.
$49 a month or $490 a year. You get 10 GB of storage.
If you need more storage, it costs $0.50 per GB-month, prorated, and you approve it through Stripe first. On the Free plan, you need to upgrade before you can add storage.
You get your 250,000 signup credits once. They don't refill, there's no monthly free top-up, and they don't roll over. Now and then we may hand out promotional credits.
When you sign up for a free account, you're entered in our monthly Workflow Workshop. Each month we pick one person's workflow problem to automate. Over seven days we write down how you work, find the spot where automation helps you most, show you how Conceiver works, and build the solution with you. By the end, you'll know how to take on bigger real-world problems yourself.
We record everything. Hydra-Dynamix reserves the right to use the footage in promotional material, including a tutorial video that will come with open-source code for the solution.
