Language1
Benchmarking LLM comprehension of vague prompts via Taboo
Last verified:
What is Language1?
Language1 is a daily AI prompt game where you play a reverse Taboo game with large language models. The game gives you a target word and a list of 5 forbidden words you cannot use in your clue. Your objective is to help the model identify the correct target word using the fewest guesses, minimizing token usage, and completing it in the shortest time possible.
This is a prompt engineering take on Reverse Taboo that challenges your skills in directing language models with specific input limitations. Scoring is determined by standardized tokenization—fewer tokens in your clues lead to a better score—and the game also monitors how quickly you write your clues. You can play for free without registering, but creating a complimentary account provides access to additional models.
The game includes models with parameters ranging from 3 billion to 20 billion parameters, adding an extra layer of difficulty as smaller models are harder to guide. You can play the daily challenge, race other players, and compete on attempts, tokens, and time through the leaderboard system.
Language1 is designed for prompt engineering enthusiasts, AI hobbyists, anyone interested in testing LLM comprehension, and people who enjoy word games. It serves as both a fun game and a way to benchmark how well different LLM architectures and sizes understand vague or constrained prompts.

Frequently asked questions about Language1
What is Language1?
Language1 is a daily AI prompt game where you play a reverse Taboo game with large language models. You receive a target word and 5 forbidden words, and must give clues to help the LLM guess the target without using those forbidden words.
How do I play Language1?
You receive a target word and 5 prohibited words. Give clues to the LLM to help it guess the target word while avoiding the forbidden words. The model tries to guess in the fewest attempts while you minimize token usage and time.
Is Language1 free to play?
Yes, you can play for free without registering. Creating a complimentary account provides access to additional models and features.
What models are available in Language1?
The game includes LLMs with parameters ranging from 3 billion to 20 billion. Different sizes and architectures are available, with smaller models providing more difficulty.
How is scoring determined in Language1?
Scoring is determined by standardized tokenization—fewer tokens in your clues lead to a better score. The game also tracks how quickly you write your clues and monitors the number of attempts the model takes.
What is the daily challenge?
The daily challenge is a fresh Taboo game that updates daily, allowing you to play new content and compete with other players on the same challenge using attempts, tokens, and time metrics.
Do I need to create an account to play?
No, you can play for free without registering. However, creating a complimentary account unlocks additional models and features.
Why are smaller models more difficult?
Models with fewer parameters (like 3B) have less knowledge and reasoning ability, making them harder to guide with constrained clues. Larger models (up to 20B) understand prompts more accurately.
Can I compete with other players?
Yes, you can race other players and compete on the leaderboard using three metrics: attempts (how many guesses the model takes), tokens (how many you use), and time (how quickly you complete the game).
What makes this different from regular Taboo?
This is a reverse Taboo where you give clues to an LLM instead of a human. It's a prompt engineering take that tests your ability to direct language models with specific input limitations, using standardized tokenization for scoring.
