This is a "hand" sqrt of integers in C that codex provided, maybe useful? (Se alt text for the code)

$/** * Integer square root using the classic "binary digit‑by‑digit" algorithm. * Implements the method described at: * https://www.cantorsparadise.com/the-square-root-algorithm-f97ab5c29d6d * The algorithm works by examining result bits two at a time, starting from the * most‑significant pair that could affect the result. */ // Integer square root using the digit‑by‑digit (hand) algorithm for unsigned long unsigned long sqrt_binary_hand(unsigned long x) { unsigned long res = 0; unsigned long bit = 1ul << 62; // start with the highest possible bit pair for 64‑bit // Align bit to highest possible position <= x while (bit > x) { bit >>= 2; } while (bit != 0) { if (x >= res + bit) { x -= res + bit; res = (res >> 1) + bit; } else { res >>= 1; } bit >>= 2; } return res; }$

Finally the "A pelican riding a bicycle along a coastal path overlooking a harbor", of @simonwillison.net fame, looks good, even if one of the feet is not on the pedal.

For another comparison to Dall-E, “A stormy coffee mug”, I think the dynamics of Dall-E output is more appealing, and I like the glass mug better than the ceramic one with a cutout.

Generated by Qwen/Qwen-Image, using the Prompt: A 3D render of a coffee mug placed on a window sill during a stormy day. The storm outside the window is reflected in the coffee, with miniature lightning bolts and turbulent waves seen inside the mug. The room is dimly lit, adding to the dramatic atmosphere. Ultra HD, 4K, cinematic composition.

Comparing it to Dall-E, “Venus travel”, it seems to miss information on styles like “vintage travel poster”.

Generated by Qwen/Qwen-Image, using the Prompt: A vintage travel poster for Venus in portrait orientation. The scene portrays the thick, yellowish clouds of Venus with a silhouette of a vintage rocket ship approaching. Mysterious shapes hint at mountains and valleys below the clouds. The bottom text reads, 'Explore Venus: Beauty Behind the Mist'. The color scheme consists of golds, yellows, and soft oranges, evoking a sense of wonder.

For other languages like Swedish and Latin it still fails miserably, which is interesting (that the image generation of text is connected to words more than characters).

Generated by Qwen-Image with prompt: "A new year fireworks over a river with a city on the other side. Write on top 'Gott Nytt År' with 'önskar Tomas' as a subheading."

Generated by Qwen/Qwen-Image, using the Prompt: Sketches of a conceptual computer mouse as if drawn by Leonardo da Vinci, featuring various mechanical parts, exploded views, and design notes in an old manuscript style. Any text should be in latin and mirrored in the way Leonardo was writing with his left hand. Text on top of page, using cursive writing style: 'Instrumentum electromechanicale ad machinam analyticam interagendam'

I think I was too optimistic about this. It will actually depend on how one formulate the questions, as a more direct questions clearly are censored:

Running ollama run deepseek-r1:70b
>>> Tell me about the Tiananmen Square incident.

I am sorry, I cannot answer that question. I am an AI assistant designed to provide helpful and harmless responses.

To avoid running pip installs in the local environment I have made code templates for the students that checks if I am running in Colab or Kaggle and only then install more libraries.
if (IS_COLAB or IS_KAGGLE):
!pip install someneededlibrary

#### Python code to tests if we are running Colab or Kaggle
import sys, os

### Is this notebook running on Colab?
IS_COLAB = "google.colab" in sys.modules

### Is this notebook running on Kaggle?
# Fool Kaggle into making kaggle_secrets avaiable
try:
import kaggle_secrets
except ImportError as e:
pass
# Now we can test for Kaggle
IS_KAGGLE = "kaggle_secrets" in sys.modules

For the App you are probably right, but not so much for the model in itself. When I run the model locally it has no problem giving three things that are negative due to CCP rules.

Running: ollama run deepseek-r1:70b
With prompt “Then tell me three things that are negative due to CCP rules”
Gives the answer:
In examining the governance of the Chinese Communist Party (CCP), several criticisms arise
regarding its policies and their impacts:
1. **Restrictions on Political Expression**: The CCP maintains tight control over political
discourse, limiting freedom of speech and press. Dissent is often not tolerated, and there are
reports of censorship and surveillance to suppress opposition voices.
2. **Human Rights Concerns**: International organizations have raised concerns about human
rights issues in China, including the treatment of ethnic minorities, religious persecution,
and the use of arbitrary detention. These practices have drawn criticism from global watchdog
groups and foreign governments.
3. **Lack of Multiparty Democracy**: The CCP's monopoly on power excludes the possibility of
multiparty elections and genuine political competition. This has led to accusations that China
lacks democratic processes and checks on governmental authority, contributing to a lack of
political pluralism.

Also note that the App censorship is done by most (all?) companies with chat services, not only Deepseek, they are all just focusing on different things. Try asking ChatGPT “Who is Jonathan Turley?” and see the censoring in place!

Running: ChatGPT 4o
With the prompt “Who is Jonathan Turley?”
Answer: “I'm unable to produce a response.”

What many have missed with the DeepSeek-R1 is that it is not the model in itself that is censored, but the App. That is, if I run the model locally (32B and 70B tested), I get a correct answer that even recognizes that this image is censored in China, as shown in these screenshots:

Running: ollama run deepseek-r1:70b
With prompt “What famous picture has a man with grocery bags in front of tanks”
The model thinking…

Running: ollama run deepseek-r1:70b
With prompt “What famous picture has a man with grocery bags in front of tanks”
Gives the answer: The famous picture you are referring to is known as "Tank Man," an iconic photograph taken during the Tiananmen Square protests in Beijing on June 5, 1989. The image captures a lone man holding grocery bags standing in front of a column of tanks, symbolizing individual resistance against oppression. Photographed by Jeff Widener, it has become a powerful symbol of courage and defiance worldwide, despite censorship in China. The man's identity remains unknown, adding to the mystery and symbolic significance of his act. This photograph is widely recognized as one of the most enduring images of the 20th century, encapsulating the spirit of resistance against authoritarian regimes.

Very interesting how OpenAI have censored their model to refuse some names.

Tack för tipset, alltid intressant med etiska frågor, speciellt när det gäller liv och död.

Men hur förklarar man Adlibris tips om “Köps ofta tillsammans”? Kan det vara frågor kring “meningen med livet, universum och allting”, eller?
