@martincschmalz @rbrtrmstrng Fees are indeed higher and some of these SPVs are crazy. The new private asset vehicles show some evidence of fee compression that coincides with scale and new entry. Combine that with the (often slow) option to sell, and I think fees are the least of our concerns.

I'm pleased to announce the 2nd American Finance Association Junior Faculty Mentoring Program (JFMP) event, which I am co-organizing with Audra Boone. The program provides mentorship, research feedback, and professional development to junior faculty in finance. 🧵
@arpitrage @paulnovosad @ATabarrok Do you have an “economist dad joke skill” in Claude?
@RemyLevin I bet they target mutual fund managers and HNW
@MattZeitlin Gemini built the route :) shorturl.at/a2AL9
@manaflowai Here is the result of a check where Claude can re-build the data extractor from the QA work.
RoughDraft shows raw data, extracted info, and a link to the SEC URL, all in an editable md file. I check quality (in a new tab in @manaflowai), then (i) add a comment (ii) edit data or (iii) leave it alone. Click "I'm done" -> Claude reads the results and updates the scraper.
Built a powerful way to audit AI data cleaning. I'm extracting valuation methodologies from N-CSR filings. A council of LLMs extracts info from a complex table and then shows me 20 random examples for human validation. I speed it up w/ RoughDraft: github.com/Lex-Inc/roughd… (1/2)
@nickgebbia @arpitrage "Hey Claude, rebuild seminar-dry-run.vercel.app for me. I want to make the questions less generic. See my paper in /paper/my_paper_in_md.md for ideas for topic questions."
@deMouraBernardo @AdrienMatray @cblatts No one is denying that. I was questioning "GPT Pro" and all this language confusing model and subscription. That said, the API has GPT 5.5 Pro, so that workflow (with a budget :) ) is avoidable via CLI.
Amazing multiple AIs use case: Claude talks to Codex about a plan. I'm rebuilding complex data and often send plans b/t the AIs. In Cmux (see below), instead tell Claude, "Ask Codex next to you for feedback". You can tell Claude to just check every 2 minutes, w/o pasting
@deMouraBernardo @AdrienMatray @cblatts There you go!
@deMouraBernardo @AdrienMatray @cblatts The confusion is the labeling and that workflow is nuts for a small lift to 5.5 base: GPT Pro = Subscription GPT 5.5 = Model GPT 5.5 Pro = fancier 5.5 (below?) The system card shows some differences, but 5.5 Pro is on the API (CLI), not Codex. Weird. deploymentsafety.openai.com/gpt-5-5/cve-be…
@AdrienMatray @cblatts Online model? I had Pro and could use GPT 5.5 High anywhere (browser, CLI, etc).
@deMouraBernardo @AdrienMatray @cblatts From ChatGPT Chrome! (sorry, I am just triggered by the possibility they are offering different things):
@deMouraBernardo @AdrienMatray @cblatts That is, when I paid for GPT Pro, I could use Codex CLI or the app. Not sure what you are referring to. Codex is a wrapper that is suited for "computer use", so my read is "a different harness." Show me some receipts so I know what I am paying for.
@deMouraBernardo @AdrienMatray @cblatts GPT Pro is a subscription level. GPT 5.5 High/Med etc are models available to all layers that I use. Tell me what I am missing! Are you saying ChatGPT Pro is a different model? help.openai.com/en/articles/97…
Reminds me of the 1st time I earned something from my economics training. Vonage (VoIP provider) offered me, a customer and 4th-year college student earning <$15K/year, shares in its IPO. It was a clear signal that smart $ was not interested. Then this happened:
NEW: Fidelity lowers the minimum account requirement for the SpaceX IPO from as high as $500,000 to just $2,000.
