# Models & tiers

Foxora resolves a concrete model from two things: the agent's role and the tier it's running at. Tiers — Fast, Pro, Max — set the class of model; your plan gates which tiers you can use.

## role × tier → a model

Two inputs, one model. The agent’s role says what kind of brain it needs; the tier says how capable. Foxora’s gateway combines them — role × tier — into a concrete model, with a provider-fallback chain so a single outage never stalls a run. You never name the model.

## The three tiers

- Fast — snappy, low-latency models for everyday tasks.
- Pro — the default; strong general-purpose work for serious, multi-step jobs.
- Max — the most capable models for your hardest reasoning and trickiest builds.

> Tier names in SettingsIn Settings → Models the managed pools read Fast, Premium, and Max — the Pro tier you pick on a crew is the Premium pool. Same thing, two surfaces.

## Tier lives on the crew

You usually don’t set a tier per agent — you set it on the crew. A crew is a lineup of agents led by an orchestrator, and the crew’s tier is the pool every member routes at. Foxora ships three built-in crews that share one lineup and differ only by tier:

- Foxora Auto — the Fast tier; everyday autonomous work, fast and economical.
- Foxora Pro — the Pro tier; stronger reasoning and coding for serious work.
- Foxora Max — the Max tier; frontier models for the hardest problems.

Switch crews in the composer to move your whole workforce up or down a tier in one move — same agents, same roles, a different class of brain.

## Plans gate the tiers

Which tiers you can run is gated by your plan’s feature flags. The Max pool, for instance, is a Max-plan capability. In Settings → Models, pools your plan doesn’t unlock are shown but locked — upgrade to enable them.

> Design for FastThe Fast tier is the benchmark to design against: if your agent, role, and skills work well there, they only get better at Pro and Max. Reach for a higher tier when you hit a real quality wall, not by default.
