Ask once. Answer with the model that fits the task.
Mimir.SI Chat™. Every frontier model, one conversation. Ask a question and pick the model that fits the task. Mimir.SI Chat puts the current frontier models from every major lab behind one composer, so you can move between them without moving your work.
The name
The head that answers, asked a different way.
Odin did not only ask Mímir one kind of question. The head was kept because it knew things no single living mind did, and it was consulted whenever the answer mattered more than the asking.
Mimir.SI Chat is the same well, drawn from differently. No single model is best at everything, so the question goes to whichever one fits: the reasoner for a hard problem, the fast one for a first pass, the coder for the implementation. The well is the same. The bucket you lower is your choice.
Mímir/Old Norse, a name kin to “memory”
What it does
The right model for the question.
No single model is best at everything. Mimir.SI Chat lets you reach for the one that is, without leaving the conversation you are already in.
Choose
Choose the model
Pick from the current frontier models across every major lab, filtered by what the task needs: reasoning, speed, vision, coding or a long context.
Switch
Switch per task
Move between models inside the same conversation. The transcript stays, so you can ask a second model to check the first.
Keep
Keep the thread
Every conversation is saved to your account, with the model that produced each answer, so you can return to it later.
Connected
It works with the rest of the platform.
Mimir.SI Chat is a general assistant. Where a question belongs to a specific product, it points you there rather than guessing.
For questions about your own machines and records, Mimir.SI (the plant-floor copilot) answers from your documents with citations.
Plant floor
Mimir.SI
Answers questions about your equipment from your own manuals and history.
Compliance
Heimdall.SI
Classifies AI systems against the EU AI Act and keeps the evidence.
World models
Norns.SI
Simulates how a physical system responds before you act on it.
Use cases
Wherever the model matters.
The same question can land differently on different models. Mimir.SI Chat makes that a choice rather than a constraint.
Hard reasoning
Reach for a reasoning model when the problem needs working through, not recalling.
Fast drafts
Use a fast model to get a first pass, then a stronger one to refine it.
Code
Pick a coding model for implementation, review and refactoring.
Long documents
Use a long-context model to work across a whole report or codebase.
Second opinions
Ask a different model the same question and compare the answers.
Cost control
Match the model to the task instead of paying frontier prices for routine work.
