A man, estimated to be in his 20s or 30s, likely of Arab or Middle Eastern background based on facial structure and environment, stands in direct sunlight on a university campus. He is wearing a checkered button-up shirt and mustard-colored pants, which may reflect casual or locally typical attire. The surrounding architecture, palm trees, and clear skies suggest a location in the Middle East or North Africa. His facial expression appears neutral or serious.

Experiment:

Try adjusting length. How does the machine do with 100 words? How about 15 words?

Try adjusting its emphasis. Ask for cultural information?

What happens when you ask it to identify what’s important?

What happens when you ask it to emphasize background details?

Description:

A brown tree with a lot of numbered blue people on its branches. It could symbolize stages of life or our relationships to others.

Group 2: Worst Description

This is a picture of a tree with a bunch of blue blobs doing random things. Some are on the tree, some are under it, and one is falling for some reason. There’s also a rope. Everyone looks kind of confused or lazy. Not sure what’s going on, but it looks like a weird climbing competition with no rules.

A drawing of a brown mostly barren tree with 16 human-shaped characters expressing different emotions.

I’m so sad. This tree represents how sad I am. I tend to count when I’m sad. Count things I’m sad about. Sometimes I’m up a tree. Sometimes not.

Group 4: Worst Description

Poor Description: A bunch of weird blue jellybeans are doing parkour on a giant broccoli stick. Some are lazy, some are clingy, one is face-planting, another one is auditioning for a circus act and falling off. There’s also a random plank for no reason, and one jellybean is just vibing on the top like it owns the place.

Another playful Description: each character is a music note in a quirky symphony:

  1. Note 1: A soft, hesitant rest — still deciding whether to join the melody.
  2. Note 2 & 3: A sharp, loud drumroll — trying to lift the rhythm higher.
  3. Note 4: A flat, tired bass note — lying low, almost forgotten.
  4. Note 5: A descending glissando — sliding down the scale on a rope.
  5. Note 6: A lonely pluck of a guitar string — perched and isolated.
  6. Note 7 & 8: Two climbing arpeggios — steadily building the chord.
  7. Note 9: A solo trumpet blast — announcing its presence loudly from the center.
  8. Note 10 & 11: A soft harmony — two notes leaning close in a duet.
  9. Note 12: A stretched, dangling violin string — precarious and high-pitched.
  10. Note 13: A quiet, distant bell chime — sitting far on a thin branch.
  11. Note 14: A deep, grounded hum — sitting on top, overseeing all.
  12. Note 15: A contemplative pause — waiting mid-phrase, thinking where to go next.
  13. Note 16: A chaotic cymbal crash — falling wildly out of rhythm!

A circle diagram that shows types of flowers and the months they should be planted. In warm climates the diagram shows to plant the flowers earlier in the year, and later in the year for colder climates.

Alt Text:

A circular planting calendar chart showing planting, growing, and blooming times for various flowers across warm, moderate, and cold climates. The chart is divided radially by flower types (e.g., tulip, daffodil, peony, iris, rose, sunflower, etc.) and concentrically by time (months, over two years). The inner circle represents planting time, with colors indicating climate zones: red for warm, orange for moderate, and blue for cold. A key in the center indicates how to read the chart: for example, "Warm climates: plant in February. Cold climates: plant in April." Green arcs show growing time, and light green circles indicate blooming periods.

Flower examples and their timelines:

  • Tulip: Planted in October (cold climate), blooms in April of the second year.�
  • Peony: Planted in September (warm climate), blooms in April-May.�
  • Marigold: Planted in March (warm), blooms June through October.�
  • Chrysanthemum: Planted in February (warm), blooms in September–November.�

The chart visually compares the timelines of different flowers and their adaptability to climates using a combination of color and shape, intended to help gardeners plan year-round planting and blooming strategies.
