Hidden Costs Breakdown

1

W&B Training Inference Costs

medium addon

Inference when using W&B Training is billed based on total input and output tokens, for example, the Qwen3 30B A3B model is priced at $0.10 per 1 million input tokens and $0.30 per 1 million output tokens.

industry

For example, the Qwen3 30B A3B model is priced at $0.10 per 1 million input tokens and $0.30 per 1 million output tokens

2

Data Acquisition and Preparation

high implementation

This general fine-tuning cost, not W&B specific but essential for implementation, can constitute 30-40% of the total fine-tuning cost, including expenses for infrastructure, cleaning, annotation, labeling, and quality assurance.

industry

Expenses include data collection infrastructure ($10,000-$50,000 for enterprise systems), data cleaning and preparation (300-500 person-hours for initial datasets), data annotation and labeling ($0.50-$5.00 per data point), and quality assurance (an additional 15-20% of the preparation budget)

3

W&B Model Evaluation Tools

low addon

Using Weights & Biases tools for model evaluation can add to the cost.

industry

For example, the Qwen3 30B A3B model is priced at $0.10 per 1 million input tokens and $0.30 per 1 million output tokens

4

Additional Storage (Pro plan)

low overage

Additional storage on the Pro plan beyond the included amount costs $0.03/GB.

industry

Weave Data Ingestion: For the Pro plan, additional Weave data ingestion beyond the included amount costs $0.10/MB.

5

Evaluation Tools and Systems

medium addon

Tools like Weights & Biases itself, MT Bench, or custom evaluation scripts can add an estimated $500 to $2,000 to the overall cost.

industry

Evaluation Tools and Systems: Tools like Weights & Biases itself, MT Bench, or custom evaluation scripts can add an estimated $500 to $2,000 to the overall cost, depending on the tooling stack and team size.

6

Infrastructure and Deployment

medium implementation

Running a fine-tuned model in production incurs deployment costs.

industry

Weights & Biases' pricing for fine-tuning, particularly through its W&B Training offering, is based on active usage and comprises three main components: inference, training, and storage.

7

Compute Costs (GPU Time)

critical implementation

The actual GPU time for fine-tuning is a major cost, varying significantly based on model size, dataset, and methods used.

industry

Using Parameter-Efficient Fine-Tuning (PEFT) methods like LoRA can significantly reduce compute costs, allowing fine-tuning of a 7B model on a single 24GB consumer GPU, which would otherwise require approximately $50,000 in H100 hardware.

8

Inference and Serving Costs

high overage

Deploying and running the fine-tuned model incurs ongoing monthly costs.

industry

For example, a 7B model served with vLLM or TGI might cost $2,000 to $4,000 per month, a 13B model $4,000 to $7,000 monthly, and a 40B model can easily exceed $10,000 each month in real-world usage.

9

Storage

low overage

W&B Training stores checkpoints of trained LoRA models, billed monthly based on total checkpoint size and the pricing plan.

industry

Storage is billed monthly based on total checkpoint size and the pricing plan, with all plans including some free storage.

10

Usage-based Billing Overages

medium overage

Even paid tiers can incur overage charges for extensive runs or storage, especially when using AWS, GCP, or Azure cloud services.
