Every AI turn has to run somewhere. Argand decides where.
Five things get chosen every time an agent does anything — the folder, the hardware, the model, the harness, the cost. Today you pick them by hand, or you don't get to pick at all and everything lands on the most expensive option.
Not an IDE. Nobody sits in it.
It sits underneath the tools you already use.
What gets decided, every turn
Folder
Which repository or workspace the turn actually operates in.
repo · worktree · scopeHardware
The machine underneath. Selectable, not something you degrade into.
laptop · serverrented GPU · none
Model
Frontier when the work needs it. Open weights when it doesn't.
frontier APIlocal open weights
Harness
Which agent runtime wraps the turn. The axis nobody else automates.
Claude Code · CodexGemini · raw API
Cost
Which tier the spend lands on — with a ceiling that holds.
metered · cappedMost agent work is cheap work
Extraction, drafting, classification, routing, screening. None of it needs a frontier model — but almost all of it gets one, because nothing is deciding otherwise.
At any plausible seat price, routing every turn to the most capable model available costs more than the seat. This is the wall every agent platform is currently walking into.
Stanford's FrugalGPT work reports roughly 95% of frontier quality at about 14% of the frontier calls. The mechanism is published. As of today, no funded product does it automatically.
The market split in two, and neither side crossed
Model routers
- Route across model and provider APIs
- Deep catalogues, real traction, well funded
- Will happily call a local endpoint — as one more URL
Compute schedulers
- Place workloads across clouds and spot markets
- Gang scheduling, failover, GPU monitoring
- Excellent at deciding where code runs
And nobody automates harness selection at all — the closest tools make it a setting you configure once, not a decision made per turn. Argand is the join: one control plane, five axes, resolved together.
Run it yourself, or don't
Same arbitration layer at every rung. What changes is who owns the machine and who carries the operations.
Honestly, early
The routing layer runs in production today — on one operator's system, which is the point of saying so.
- Per-turn execution target across folder, tier, harness and model
- Four agent harnesses behind one interface
- Cost accounting by tier
- Records where a turn actually ran, not just where it was sent
- Local model serving and rented-GPU provisioning
- The spend ceiling
- Machine-enforced authority per turn
- Automatic selection — the part that matters most
It’s being built in the open.
No waitlist theatre and no launch date. If you run agent work at enough volume that the bill has started to matter, that’s the conversation worth having now — while the routing policy is still being shaped by real workloads.
Alpha. Invite only. Nothing has been validated on anyone but the operator — and that’s the first thing we’re trying to fix.
