InertialAI

Pay for what you use.
Nothing else.

No subscriptions, no minimum spend, no sales call. Every new account starts with $5 of free usage — enough to embed, forecast, and train your first model.

Call the models

Metered per request. The rate is the whole price — no platform fee, no tiers.

Finetune on your data

Training is priced on the data you train on — per million training units, with a $5 minimum per job. A first experiment costs about a coffee; a production dataset scales linearly. If the tuned model doesn't beat the base on the held-out eval, the fee refunds automatically.

The production forecaster, trained on larger GPUs

A training unit is one text token; four time-series points count as one unit. Rates are for LoRA adapters — full finetunes update every weight and bill at 4× the rate. $5 minimum per job. Datasets and finetuned weights are stored free (up to 10 GB of retained datasets per account).

Deploy and serve

Finetuned models serve on a dedicated GPU, billed by GPU time at the hourly rates below. A call is metered wall-clock, cold-start included; always-warm replicas bill hourly while reserved. Scale-to-zero endpoints cost nothing between calls.

T4$0.97 / GPU-hourFirst experiments and light traffic
L4$1.32 / GPU-hourThe default for Chronicle finetunes
A10G$1.82 / GPU-hourProduction endpoints at steady load
L40S$3.22 / GPU-hourBigger batches, lower latency
A100 (40 GB)$3.47 / GPU-hourHeavy models
A100 (80 GB)$4.13 / GPU-hourHeavy models, larger context
H100$6.52 / GPU-hourLatency-critical serving at scale

Rates are for the auto region; pinning to a specific region bills at 1.25–1.5× the listed rate.

Full validation before payment

Every record of your file is checked — shape, modalities, labels — and you see exactly what a run will cost before paying a cent.

Before/after eval on every job

Each finetune ends with a held-out comparison against the frozen base model. If your model doesn't beat the base, the training fee refunds automatically.

Deploys, versioning, rollback

One call turns a finetune into a private endpoint with scoped keys, version history, and one-call rollback.

Zero idle cost

Scale-to-zero endpoints cost nothing between calls, and every endpoint has a hard spend cap — alert at 80%, suspend at 100%.
