Levent Alpöge
Vintage: 2026-09. Primary evidence is Buckmaster’s fetched statement PDF as synthesized in 2026-09-08-x-morning-buckmaster-alpoge-ai-fluid-proofs-openai-credit. Not a diarized source — claims are source-attributed. No independent Alpöge primary this pass.
Levent Alpöge
One-line summary: Anthropic-affiliated mathematician; collaborator with tristan-buckmaster on Lean-checked smooth-forced IPM / Boussinesq / 3D Euler blowups (announced 8 Sep 2026). Buckmaster alleges OpenAI proposals that would drop him from credit — contested.
What it is
A named collaborator in Buckmaster’s statement. The clip identifies him as Anthropic’s Levent Alpöge. This page exists so the math and credit-dispute pages have a durable person-link. Full math: buckmaster-alpoge-forced-blowups. Full dispute: openai-fluid-proofs-credit-dispute.
Why it matters to this thread
Frontier-lab employment + AI-assisted formal math. The statement says the collaboration is personal — “free of any institutional agreements” with either employer — and that Alpöge was not on the Sep 6 calls with sebastien-bubeck.
Key facts (from 2026-09-08-x-morning-buckmaster-alpoge-ai-fluid-proofs-openai-credit)
- From 2026-09-08-x-morning-buckmaster-alpoge-ai-fluid-proofs-openai-credit (statement PDF): co-author of the three public forced-blowup results; Lean repo github.com/tristanbuckmaster/fluid_lean.
- From the same source (same PDF): Alpöge not on the Sep 6 calls with Bubeck. Buckmaster alleges two proposals — coordinated announce, or Buckmaster alone writing OpenAI’s NS result while dropping Alpöge (twice, citing Anthropic employment as “annoying”). He declined. Allegation, not established fact.
- From the same source: sebastien-bubeck (@SebastienBubeck) called the circulating allegations “false and inflammatory.”
Afternoon OpenAI / Bubeck account (from 2026-09-08-x-afternoon-openai-navier-stokes-images-2-5)
- From 2026-09-08-x-afternoon-openai-navier-stokes-images-2-5 (@OpenAI + issuer Concurrent work): OpenAI congratulates Alpöge & Buckmaster; forced-Euler priority; no-specific-user-data language.
- From the same source (@SebastienBubeck): Bubeck says he did not ask to remove Levent from Levent’s own Euler authorship; Levent declined meetings. OpenAI-side account — no independent Alpöge statement in this clip either.
What this source does not establish
- No independent Alpöge statement fetched this pass (morning or afternoon).
- Not a rewrite of anthropic ARR / FLT / AAR pages. Employment is color on the collaboration, not a lab SKU.
