Does "pacing" mean more alignment compute and lower lab margins — not less spend?
Gavin Baker argues Anthropic/OpenAI "pacing" is more compute on alignment, monitoring, and evals at the cost of slightly lower margins — not a capex cut. Roon frames pacing as asymmetric margin compression; xEBITDA argues safety spend can raise total semiconductor demand.
The read
Baker has the better of the mechanism claim: the posts that engage the economics treat "pace" as a reallocation of compute toward alignment/evals/monitoring, not as a sudden stop to model spend. What is unresolved is magnitude — whether "slightly more" compute is billions (as one reply insists) and whether duty-of-care framing before IPO is load-bearing or decorative. The tail of the thread is unread; most visible replies are agreement, politics, or low-signal.
State of play
After lab commentary and market reaction to an AI "slowdown," Baker states that Anthropic and OpenAI will pace the frontier by spending more time and more compute on alignment, monitoring, and evals, accepting lower margins. He quotes roon that pacing compresses frontier-lab margins asymmetrically. Replies from xEBITDA push a bullish semiconductor implication: safety workloads are memory/storage-intensive and can raise total infrastructure dollars even if capability progress per dollar slows. Stakes: whether Monday's AI-stock dip prices a real demand destruction or a margin/mix shift.
Fidelity note: top-replies only — deep reply tail unread.
The positions
Pacing is more alignment compute, lower lab margins. @GavinSBaker [named] [book] — 'spend slightly more money on compute at the cost of lower margins' @tszzl [named] [principal] — 'compress the margins of the frontier labs' / 'terrible regulatory capture tactic'
Safety reallocation can raise total semiconductor demand. @xEBITDA [pseudo] — '$80 capability + $40 safety' → total spend '$120, not $80'; also 'more bullish for memory than GPUs at the margin'
"Slightly more" understates the bill / profitability risk. @EcoDogFanJM [pseudo] — 'we're talking billions in incremental compute' @tweetmaster153 [anon] — labs 'not profitable' and must 'spend even more' while slowing the revenue driver
Weight of the room
Baker (Atreides CIO) and roon (OpenAI-affiliated voice, marked principal on the quote) carry the named weight. xEBITDA supplies the only falsifiable arithmetic in the visible replies. Anonymous profitability skepticism is present but not evidence. Engagement volume is high; it is not used as proof.
What would settle it
Frontier lab gross-margin disclosure that isolates alignment/eval/monitoring compute as a rising share of COGS or opex Knowable — next 1–2 earnings / IPO filings from Anthropic or OpenAI path vehicles — by 2026-12-15 earliest useful checkpoint
Hyperscaler or neocloud commentary that safety/evals workloads are adding incremental GPU/HBM hours rather than displacing training Knowable — next major cloud earnings Q&A cycle — fall 2026
Public model-card or system-card language that quantifies eval/monitoring compute relative to training for a named frontier release Knowable — next major model release cycle — through Q4 2026

The way that Anthropic and OpenAI are going to “pace” the frontier is by spending more time and more compute on alignment, monitoring and evals.
The frontier labs that choose to “pace” likely spend slightly more money on compute at the cost of lower margins.
That’s it.

Many factors would go into the lower margins, but incremental compute spend on alignment would be one.
Don’t take it from me, take it from a senior OpenAI employee:

for the skeptics in government and elsewhere: “pacing the frontier” will compress the margins of the frontier labs. it is a heavy cost imposed asymmetrically on model developers with the strongest AIs in America. by its nature, it would be a terrible regulatory capture tactic

And while this is all coming from a place of sincerity, it may also significantly reduce their contingent liabilities by showing a “duty of care.” Important and responsible step before going public.

@GavinSBaker How much memory infrastructure does it take to train, align, evaluate, monitor and safely deploy GPT-N?
That number is going up faster.
There is also a nice capex implication. Suppose previously $100 of frontier-model infrastructure spending consisted of $80 capability scaling and $20 safety/post-training. If the labs "slow down" by moving toward $80 capability + $40 safety, total infrastructure spend becomes $120, not $80. Capability progress slows relative to compute consumed, while semiconductor demand rises.

@GavinSBaker This is arguably more bullish for memory than GPUs at the margin, because the policy response to AI risk seems to involve more inference, more evaluation, more checkpointing, more monitoring and more data retention. All workloads with unusually high memory/storage intensity. $MU

Slightly more money is doing a lot of work in that sentence .. we're talking billions in incremental compute

2026-09-16 — OpenAI principal quotes land on Baker's mechanism. Overnight @GavinSBaker posts CNBC-attributed Sarah Friar (OpenAI CFO): focused on "getting more compute to keep that flywheel going," and Sachin Katti (OpenAI VP of Compute Strategy): safety/alignment will require "even more compute." Baker: if you thought pacing was negative for AI infrastructure demand, "think again." He also calls Monday's infrastructure selloff almost "Deepseek"-level silliness. Visible pushback (@CZituo): pacing was about when spend lands, not the level — a CFO wanting more compute today does not settle the curve. CNBC Friar piece separately: she would listen to researchers on pacing and still make "strong ROI" investment decisions (CNBC).
More on AI pacing: Sarah Friar CFO of OpenAI yesterday on CNBC: “from where I sit today there is so much opportunity to drive growth that I am still highly focused on getting more compute to keep that flywheel going.” … Sachin Katti … “we’ll need even more compute to make sure future models are more safe and aligned.” If you thought “pacing” was negative for AI infrastructure demand, think again. — Gavin Baker (@GavinSBaker)
Kind of weird the market viewed this as negative infrastructure. This seems wildly bullish infrastructure but highly uncertain for short term to maybe medium term model layer margin structure. — Paul Enright (@pmje73)
Yes. Almost a “Deepseek” level of silliness on Monday. Almost. — Gavin Baker (@GavinSBaker)
pacing was never an argument about the level, it's about when the spend lands. both quotes answer how much, which nobody was really arguing. the bear case is the shape of the curve, & a CFO saying she wants more compute today doesn't settle that either way. — Chen Zituo (@CZituo)
