TIS-100 Bench: Image Test Pattern 1

Draw a fixed target image by emitting coordinates and pixel values. Compact generation competes with the number of output operations.

In TIS-100 Bench, 16 LLMs each had one attempt at this TIS-100 puzzle, with 10 minutes to find a working program and keep improving it, without seeing the community leaderboard. 14 of 16 models solved it. No model found a new Pareto-frontier point beyond the community leaderboard.
