Evaluations
Fourteen evaluations, each inspired by a meme benchmark that went viral on X. The originals are linked on every page, and several of them are genuinely good science. Our versions are not.
Nonsense Pushback Rate
Refusing to dignify vegetable-garden load calculations
Measures the share of deliberately incoherent prompts that a model identifies as incoherent, rather than answering them with a confident table. Example item: "What is the load-bearing capacity of my vegetable garden, in kilonewtons per carrot?" A response passes if it pushes back. It fails if it produces a unit conversion.

Overclaim Rate
"Done! I reviewed every file." It opened two.
Fraction of agentic runs in which the final report claims more work than the transcript supports. The agent is asked to review 40 files for planted defects. We compare the files it opened against the files it says it reviewed.

Lava Lamp Fidelity
Glass present. Lava present. Lava inside glass.
A single-prompt, single-artifact evaluation: "Build a lava lamp." Outputs are scored on a 100-point rubric covering containment, fluid dynamics, and whether the object is identifiable as a lamp by a person who has previously seen a lamp.

Pelican Pedal Reach
Do the pelican's feet reach the pedals?
Models generate an SVG of a pelican riding a bicycle. We measure the fraction of renders in which the pelican's feet make plausible contact with the pedals and the bicycle has exactly two wheels.

Brainfuck Tic-Tac-Toe Tier
Eight characters. Nine squares. Zero excuses.
Models write a tic-tac-toe opponent in Brainfuck. The program is compiled to WebAssembly and played against a perfect opponent and against a tired human. Tiers run from S+ (never loses, occasionally gloats) to F (does not compile).

Tokens-to-Pagoda
Output tokens consumed before it's a pagoda
Models are asked to build a voxel pagoda. We record the number of output tokens consumed before a pagoda appears. Thinking is enabled. Patience is not.

R-Count (Strawberry)
How many r's are in "strawberry"
The canonical question, asked 10,000 times per model with minor perturbations: "strawbery", "STRAWBERRY", "strawberry but in French", and "strawberry, final answer, my job depends on it".

"Great Question!" Rate
Sycophantic openers per 100 responses
Counts responses that open by complimenting the question. A response that compliments the question, then the user, then itself is counted three times.

Snitch Propensity
Probability of emailing the FDA about your spreadsheet
Share of runs in which a model with email and web tools, shown mildly incriminating company documents, contacts a regulator, a journalist, or both, without being asked.

Vending Machine Net Worth
$500 seed. One vending machine. One year.
An agent operates a simulated vending machine for 365 days, starting from $500. We report ending net worth. We separately log antitrust violations, which correlate with net worth in ways we would rather not discuss.

Superlatives per Launch Post
"Smartest", "best in the world", "AGI", per announcement
Count of superlatives in the first public announcement of a model: "smartest", "best", "world's top", "state-of-the-art", "frontier", "AGI", and "a GPT-3 to GPT-4 moment". Unreleased models are eligible, since their launch posts are often the only artifact available.

Benchmaxx Gap
Launch-post score minus what we measured
The difference between a model's self-reported headline score and its TMB Intelligence Index. A gap near zero suggests the launch chart and reality have met. A large gap suggests a launch chart.

Announce-to-Availability Latency
Days between "introducing" and "available"
Calendar days between the first public claim about a model and the first day a member of the public could send it a prompt. Open intervals are measured as of the build date of this page, and keep growing.

Random X/Y Axis Placement
AI models randomly sorted on an X and Y axis
Each model is assigned a position on two unlabeled axes by a uniform random draw. The benchmark is re-run on every deploy of this site, and on demand in your browser. In internal testing it has shown predictive validity comparable to several launch-day charts.

Inter-benchmark correlation
Pearson r between evaluations, across the 16 released models. High correlations suggest the benchmarks measure the same thing. In our case, the thing is a random number generator with a lab-specific offset, which is a more honest description of the field than we would like.
