Train AI models on Bittensor

You want a custom AI model trained on your own data. Gradients is the easiest place to start because it doesn't need machine learning knowledge. Aurelius can check your dataset before you pay to train, and iota is for bigger training jobs.

Start with these 3

SN56Live

Gradients

Train a custom image style or fine-tune a text model from the web app, with no ML know-how.

First stepTrain an image style model on 20 of your own pictures. Check the price first, because it didn't load for us.

Web app and APIPricing not listed

Prices didn't load on the pricing page, so costs are unverified.

Aurelius

Predicts what a dataset will teach a model, including bad habits, before you pay to train it.

First stepRun your candidate dataset through Proba before any training run.

Web appPricing not listed

There's a 'Launch Proba' button, but the site doesn't state pricing, sign-up or whether it's beta.

SN9Live

iota

Runs larger training jobs across many machines, yourself with an SDK or managed by the team.

First stepEmail the team with the size of the job you have in mind.

APIPricing not listed

No pricing or sign-up is described; the managed option starts by emailing the team.

Type a description and get a 3D model, in the browser or inside Blender, Unity or Unreal.

  • Generate a 3D model from a text prompt in the web app
  • Use the free Blender plugin from Gumroad
  • Use the free Unity plugin from the Unity Asset Store
Web appFree

Plugins are stated as free; the web app's pricing and sign-up aren't described.

SN26Beta

Perturb

Tests your image AI model with tricky inputs and sends a report on where it breaks.

  • Order a $99 robustness scan of an image classification model
  • Try a live demo that makes an image designed to fool AI
  • Contact them for enterprise testing with CI/CD and SLAs
Web appPricing not listed

Only image classification models are supported now, the Pro plan is early access and orders go through a contact form.

Score

Build, train and run AI that understands camera video, like detecting, tracking and counting objects.

  • Build vision AI workflows visually and deploy to cloud or locally
  • Upload and label images, with saved dataset versions
  • Train a model or pick ready ones for detection and tracking
Web appPricing not listed

Score Studio has open sign-up, but pricing and beta status aren't stated on the page.

Questions

Do I need TAO to use these?

Gradients, Aurelius and iota don't say on their site how you pay, so check before you sign up.

What doesn't Bittensor cover yet?

Pricing is unclear for most training subnets, so get a quote before you plan around one.

What is a Bittensor subnet?

Bittensor is a network of 128 subnets. Each one is a competition where miners do a job, like serving AI models or renting out GPUs, and validators score the work. Some subnets also sell what they produce as a normal product. This guide only recommends those.
