AI Inference FLOPs Replace Tokens as Currency

AI Inference FLOPs Replace Tokens as Currency

Instead of the gold standard, we can imagine an inference standard of exchange, the FLOP. (As opposed to tokens, this accounts for AI ability) With some AI help, I figure $1 buys roughly 10^17 managed-LLM inference FLOPs. So that $4 coffee would...

Persistent Gender Gap in AI Use Remains Unaddressed

Wish there was information about where this data came from, but this is a very significant change. Since AI use comes from experience, the persistent gender gap in AI use across every study of AI was something that a lot...

AI's Cycle: Hype, Minor Wins, Questionable Breakthroughs

This is becoming a pattern in AI that makes talking about capabilities challenging. First, there are overstated claims (like the flubbed Erdos problems last year), then minor wins (AI helps with discovery) then breakthroughs. The first stage feels like (&...

Compute Limits Trap AI: Stalling Growth Now and Later

Compute constraints are a double bind: On the inference side you need to either (a) raise prices, (b) ration use, and/or (c) serve worse models. This hurts current growth On the training side, you can't train the next gen of models to...

AI Model Names Mislead: Claude 3

Given the messy naming scheme used by all the AI companies, I caused a chart to be made showing the gain in GPQA per 0.1 version in model names (estimated, since model names skip version numbers). There has never been...

Model Version Numbers Don’t Reflect Actual Ability Gains

Model Version Numbers Don’t Reflect Actual Ability Gains

Version numbers are not a very useful way to understand model ability gains at this stage. Unfortunately that means that if you aren’t following closely, you would expect that 5.4 is a small gain over 5, or 4.6 a small...

US Labs Lead Frontier AI Race by Months

And this is a very generous definition of notable. If we are talking frontier models, only the US and China that are even in the race. And that obscures the fact that the Big Three US labs really do seem to...

Most Future Data Centers Will Shift to Rural Areas

Interesting: "Currently, 38% of Americans live within 5 miles of at least one operational data center... Living near a data center doesn’t have much of an effect on public opinion about the facilities." From now on, it looks like most DCs will be rural....

Soon, at each gradual improvement level of AI, you will start to see large discrete jumps in ability in economically important areas, because the previous AI ability level in some aspect of the job bottlenecked progress. When bottlenecks are released,...
