# Estimate on-demand model resource cost

`POST /rl/model-resources/estimate-cost`

Estimates a model resource's on-demand hourly price without creating it.

## Request body

- RLCreateModelResourcesRequest — Request to provision a standalone model resource
  - `base_model` string, required — Base model to provision the resource for
  - `compute_config` RLComputeConfigCreateRequest — Compute layout to provision for a model resource
    - `num_generator_replicas` integer — Number of generator replicas. 0 runs the trainer only, with no generator.
    - `gpu_type` 'H100-80GB' | 'B200-SXM' — GPU type to provision. Omit to use the model's default GPU type.
  - `lora_enabled` boolean — Whether the resource hosts LoRA sessions or a single full-weight session
  - `optimizer_config` RLOptimizerConfig — Optimizer configuration
    - `adamw` RLAdamWOptimizerConfig — AdamW optimizer configuration
    - `muon` RLMuonOptimizerConfig — Advanced configuration for the Muon optimizer.
      - `scaling_strategy` 'MUON_SCALING_STRATEGY_UNSPECIFIED' | 'MUON_SCALING_STRATEGY_MATCH_ADAMW' | 'MUON_SCALING_STRATEGY_ORIGINAL'

## Response `200`
