Will I be able to generate photorealistic images?

No, and the sprint is explicit about that from the first session. Photorealism is a function of model scale and training compute, neither of which fits in two weeks on a laptop. What you get is the mechanism, on data small enough to see clearly.

Is this the same technique as Stable Diffusion or Midjourney?

The same core idea, at a much smaller scale and without the latent space and text conditioning those systems add. The final module explains exactly which pieces they have that your model does not, so you can read their papers afterwards.

Can I use images I found online?

For learning, use images you drew or that are clearly public domain. Beyond the copyright question, a consistent set of eighty of your own doodles trains better at this scale than a varied set scraped from the web.

Make images with diffusion

Take this if you have used an image generator and want to understand the process rather than collect prompts for it.

What you’ll be able to do

You can explain why generation is framed as reversing a noising process, describe what the network is actually predicting at each step, and train a small denoiser on your own image set.

What it assumes

Comfortable Python and one prior neural network, ideally the CNN sprint or equivalent.

What’s taught, in order

01
Destroying an image on purpose
Adding Gaussian noise in steps until nothing remains, and plotting the schedule. Generation is easier to understand backwards, and this forward process is the part you can see completely.
02
Learning to undo one step
The network's job is smaller than it looks: predict the noise that was added, once. Grasping that the model does not generate an image but removes a little noise is the whole conceptual hurdle.
03
Sampling, and the many-step walk back
Chaining the denoiser from pure noise to an image, watching structure emerge, and seeing what changes when you take fewer, larger steps.
04
Steering the result
Conditioning at the level this scale allows, and an honest account of how text prompting works in the large systems — which is the same idea plus a text encoder you are not training here.

What you build

Draw or collect at least eighty simple images of your own in one consistent style — doodles, symbols, letterforms. Train a small diffusion model on them and ship a grid of generated samples, the noise schedule you used, and an honest assessment of what the model captured and where it produced mush.

Check it yourself against this

At least eighty of your own images in a consistent style.
A generated grid that is clearly related to your data and not copied from it.
The noise schedule is stated and you can explain the effect of changing it.
You compared sampling with many steps against few, and reported the difference.
You can state what the network predicts at a single timestep.

Then answer this

The model only ever learns to remove a little noise from a slightly noisy image, so how does chaining that produce something entirely new?

Two or three sentences, in your own words. If you cannot, the course is not finished — go back to the module it came from.

What this course does not do

Small, low-resolution, single-style images and a model with no text encoder, so you will not build anything resembling a production image generator. Latent diffusion, classifier-free guidance at scale and the compute that makes modern systems work are all outside a two-week sprint.

Where this leads

The diffusion visualiser is free to use on its own page, and dragging the noise level up and back down is the fastest way to see the forward and reverse processes that this whole sprint is built on.
