Fine-tuning cost calculator

Dataset size, epochs, method. Out comes GPU-hours and dollars, so you know what owning your model costs before you start.

$23 × H100 · 18 minutes · 6.0M tokens at $2.49/GPU-hr

That buys one run. A build session quotes the whole project flat: training, serving, and the compounding loop that keeps the model improving after launch.

How it works

1
Size the run
Training tokens (validate your JSONL first to get this number), epochs, and the base model.
2
Pick the method
QLoRA is the budget path, LoRA the production default, full fine-tuning the maximum-quality option.
3
Read the estimate
GPU count, wall-clock hours, and rental cost at current H100 market rates.

Common questions

How accurate is the estimate?

It assumes H100-class GPUs at current market rental rates with realistic multi-GPU scaling efficiency. Real runs vary with sequence length, batch size, and checkpointing, but the estimate lands in the right bracket for planning.

LoRA or full fine-tuning?

LoRA trains a small adapter on top of frozen weights and captures most task gains at a fraction of the cost; it is the production default. Full fine-tuning updates every weight and only pays off for deep domain shifts with large datasets.

How many epochs should I train?

Two to four epochs is typical for instruction data. More epochs on a small dataset overfits; better data beats more passes.

Is the fine-tuned model mine?

On open-weight bases, yes when your platform lets you keep the weights. On Allocate, fine-tuned weights stay inside your isolation boundary and belong to you; leave, and they go with you.

What does the same run cost on Allocate?

Training runs on Allocate are quoted flat before you commit, as part of the forecast: fees and usage in writing, no surprise at the invoice. Book a build session and we scope it on the call.

These numbers are the rent-a-GPU path. On Allocate the same run is quoted flat in your forecast, the weights are yours, and every task your agents complete keeps training the model.
