I built a working AI computer by hand from Amazon parts for under $10k. It replaced a cloud bill that was pushing $10k a month.

@TheCoinCollect8 @willdepue damn you beat me to this comment

@gakonst Is there any software that isn't better when designed this way?

[Charlie Martin @char_mar_]

I was half joking when I posted this, but I'm dead serious now. Time to download those weights!

My essentials:
- GLM 5.3
- GLM 5.3 Flash
- DeepSeek V4.1 Flash
- Qwen3.8-27B

Go download the GLM 5.3 weights while you still can. The great regulatory games have begun https://t.co/J09gZxquhZ

You'll also notice something else about that chart. It reliably mean reverts. If it doesn't, then the most liquid options market in the world is not efficient. There's a strategy in that too

[Charlie Martin @char_mar_]

This holds up at every expiry too. Go out to 7-DTE, 14-DTE. Long term return is 0%. Straddles are a free hedge. A strategy that will profit whenever things get crazy and cost you nothing long term. Just be sure to combine it with other strategies.

How efficient is the market?

If you bought the SPX 0DTE straddle at 9:31 every morning since May 2022, you paid $3,422,010.

You got back $3,416,418.

1,111 sessions and you're down $5,592. That's 0.16%.

(1 lot at mids before cost)

The path is interesting..

@MyopiaCapital @Duderichy Yeah that's Citadel

From Jan 2025-Jun 2026, there were 362 trading days. Regular trading hours are 6.5 hours per day. That means that Trump's money manager made:
- 79 trades per day
- 12 trades per hour
- 1 trade every 5 minutes

@quasicoh is optimism a function of proximity to open source model creation?

@Shepher05365963 @wallstengine @jukan05 No, they're not. You might be confusing them with Citron Research

[boaz weinstein @boazweinstein]

Gonna show this to my mom who thinks she’s usually correct. @CliffordAsness I find it incredible how many problems surfaced in funds over the past month when the direction of the market has been so sharply up over the past 1.5yrs.

Relationships of all kinds breaking down. CCC rated credits at the wide end of the range with B rated at the very tight end of the range isn’t something seen before.

@yenwod_ One perk of focusing on latency first is you lose all your money faster and get back some of that opportunity cost 😀

[Charlie Martin @char_mar_]

@DeepDishEnjoyer HFT has high sample size of bets and easily measurable performance metrics. So yeah it's cooked

[Charlie Martin @char_mar_]

The game is not really about the direction of technology in history. It's about the prices you pay. In the late 1800s and early 1900s, countless people got carried out betting electricity would be ubiquitous in the future. There are no risky assets. Only risky prices.

[Will Manidis @WillManidis]

one of the great tragedies of markets is you can be staggeringly right about the direction of technology in history but if you're not willing to be near term commercial, near term prideless, you'll get carried out

no one's gonna stop you from dying young and miserable and right

@ze98426 @9K6hf1Kj6B @0xSero Oh yes they’re definitely losing money

@OddStats Sorry to say but below $667 is where put sellers begin losing money and put sellers never lose money

A computer built this entire video on it's own 🤯 https://t.co/kEll3OBAVg

This was not a one-shot

It was a two-shot

I told Fable 5.2 to make the video of it's dreams, and 9 hours later:

@zeeg @jarredsumner The part that's hardest to believe for me is $550 at API pricing. I can spend $300+ per day just building web apps at API pricing. I guess demos like this don't need authentication or unit tests or anything else a production application requires but still
