    Revenue Model

    Usage-based API fees (per token for training and inference) and hourly compute unit billing.

    Pricing Tiers

    8B Models Training
    $0.48 per 1M tokens

    Supervised fine-tuning for models with ~8B parameters.

    14B Models Training
    $1.50 per 1M tokens

    Supervised fine-tuning for mid-sized models.

    70B+ Models Training
    $2.90 per 1M tokens
