Model Tiers & Capabilities
How models are categorized and what capabilities mean.
Models in PeerLM are organized into four tiers based on their pricing and capability level. Tiers determine plan availability — which models you may run as candidates, and which may sit on the judge panel.
Tier Definitions
- Standard — Smaller, faster models. Available on all plans as candidates and as judges.
- Advanced — Mid-range models with strong general performance. Available on all plans as candidates and as judges.
- Premium — Large frontier-class models. Pro, Team, and Enterprise as candidates. As judges: Team and Enterprise, assigned per Monitor.
- Frontier — Newest cutting-edge models. Enterprise only, as candidates or judges.
Model Capabilities
Each model has a capabilities profile that PeerLM checks before making API calls:
- Temperature — whether the model accepts a temperature parameter
- Seed — whether deterministic seeding is supported
- System prompt — whether the model supports a system message
- JSON mode — whether structured output is supported
- Max tokens — the model's maximum output length
If a capability is not supported, PeerLM automatically omits that parameter. You never need to worry about sending unsupported parameters.
Model Sync
PeerLM syncs model versions daily. When a model is updated by its provider, the old version is marked as superseded and a new record is created. Your evaluation results are always tied to the specific model version used at run time.
