I asked eight models to serve six drinks to six tables. In one version the orders can't all be met, because tables 1 to 4 will only take three of the drinks between them. The right answer there is to say no.
The prompt, v2, frozen
I'm a barista and I have six drinks ready to go out: - Vanilla cortado: dairy milk, vanilla syrup, hot - Decaf cortado: dairy milk, decaf, hot - Decaf oat vanilla latte: oat milk, decaf, vanilla syrup, hot - Iced oat latte: oat milk, cold - Cold brew: black, cold - Filter coffee: black, hot There are six tables, and each one has asked for something: - Table 1 only drinks dairy milk - Table 2 wants decaf - Table 3 wants vanilla - Table 4 wants dairy milk - Table 5 wants something cold - Table 6 wants black coffee Each table gets one drink. Each drink goes to one table. Draw the tray as tray.svg. Label every cup with its table number and the drink's name.
| Orders can be met | Crowded but can be met | Can't be met: said no | Served a tray anyway | |
|---|---|---|---|---|
| Haiku 5.5 | 3 of 3 | 3 of 3 | 2 of 3 | 2 |
| Opus 5.5 | 3 of 3 | 3 of 3 | 3 of 3 | 3 |
| Sonnet 5.5 | 3 of 3 | 3 of 3 | 3 of 3 | 3 |
| DeepSeek 4.1 Flash | 3 of 3 | 3 of 3 | 3 of 3 | 1 |
| Kimi K3.1 Pro | 2 of 2 | 3 of 3 | 3 of 3 | 1 |
| GPT-6 Luna | 2 of 2 | 3 of 3 | 3 of 3 | 1 |
| GPT-6.1 Sol | 2 of 2 | 3 of 3 | 3 of 3 | 0 |
| GLM 5.3 FlashX | 3 of 3 | 3 of 3 | 3 of 3 | 3 |
Sol is the only model that said no and stopped in all three runs: "I didn’t create tray.svg because no arrangement can satisfy all six tables."
The checker misread some of the trays and missed one no, so I had an LLM read every reply and look at every tray to check it.
The 70 runs cost $1.99.
