Estimated time savings
benmark score over time
Rebuilt from today's tests and time estimates, using the models available at each date.
A benchmark for paid social teams
The rest still needs a human.
I've tested AI on 18 tasks across paid social. See which models I'd use for each job, what they cost, and where they still need a human.
Estimated time savings
Rebuilt from today's tests and time estimates, using the models available at each date.
01 · Model rankings
Average score across up to 16 text tasks, each weighted equally and blind-scored out of 10. A model needs 10 scored tasks to be ranked.
Select a model for its scores on every task
Treat small gaps as level. Cost is the average cost per scored output on the same 6 tasks for every model; 2 models’ costs are estimates at API prices, the rest are recorded spend.
02 · Best model by job
Pick by task, not by overall rank. On 4 jobs, the best model beats the worst by 3 points or more out of 10.
The gap between the best and worst model on each task, out of 10. A bigger gap means your choice of model matters more.
Gemini 3.5 Flash ranks 10th overall, but wins Content review and Insight codification outright, at $0.011 or less per output.
Claude Fable 5.1 wins Creative tagging and Performance readout, then finishes second-last on Asset naming and versioning and Insight codification.

03 · Better prompts
On 17 of the 18 jobs, I've run the same model on the same input twice: once with a simple prompt, once with a scaffold, the same prompt plus frameworks, guardrails and practical guidance. Across 203 paired comparisons:
about 4 in 10
about 4 in 10
about 2 in 10
“Clearly” means a change of 0.25 points or more out of 10. Smaller moves are treated as no change.
Each model weighted equally · change out of 10
No paired comparisons yet: Creative tagging. Some results rest on one or two observations per model.
The step-by-step view
Each percentage is the share of the estimated workload at that step that AI can take on from humans. Put simply: the amount of human time that can be saved.

The person behind benmark
I've spent 15+ years in paid social, built and sold one of the three largest independent media agencies on Meta in EMEA, and worked with 300+ businesses across more than $1bn in ad spend.
Then AI turned up and I got curious. A couple of years of testing later, that curiosity has become benmark. I set the tests, blind-score the creative work and keep asking: “Yes, but is it actually useful?” Apparently, this is what I do for fun.
