I bet we’re ~6mo from a vibe shift back to OpenAI GPT5.5 is very impressive and 40% cheaper, limits are higher. Codex is stellar and taking mindshare of the top devs I know. Teams I talk to are disillusioned with ROI from soaring Anthropic costs. It’s becoming untenable.

so what is the current industry standard to build agents? do people still use langchain/langgraph?

Insane how there's one (1) insight you need to be good at applied AI and 99% of people completely miss it

@Lux_Stella_ In 3 years we went from “it can’t do basic algebra” to “actually this proof only requires deep knowledge of graduate-level math and the intuition to challenge conventional wisdom, it’s not a true breakthrough”

bro it isn’t generally intelligent bro its only read every book and paper ever written and just making connections between them bro. its only thinking for twenty hours bro it’s just brute force thinking bro. its only solving erdos problems bro it could never be an accountant bro

Chicken is the moat. Beans are the orchestration layer. Cheese is a high-signal taste indicator. Corn is orthogonal to salsa, which will see diminishing returns as compute scales. Guac is the system of record to which all of the value will accrue.

one take that always ages really badly is that the models are intelligent enough and nobody can really notice the improvements anymore

Introducing my new model SubLinear. It's built on O(1) super-sparse attention. The context window is 1 billion and inference costs .000001 cents per million tokens. Also it gets 95% on SWE-Bench. No you cant try it out but please join my waitlist.
Alexander Whedon@alex_whedon

Introducing SubQ - a major breakthrough in LLM intelligence. It is the first model built on a fully sub-quadratic sparse-attention architecture (SSA), And the first frontier model with a 12 million token context window which is: - 52x faster than FlashAttention at 1MM tokens - Less than 5% the cost of Opus Transformer-based LLMs waste compute by processing every possible relationship between words (standard attention). Only a small fraction actually matter. @subquadratic finds and focuses only on the ones that do. That's nearly 1,000x less compute and a new way for LLMs to scale.

Corcoran is listing newly renovated Flatiron building and you are looking at ~4000 dollar per sqft which is a bit insane because this is same tier as central park tower.

@blip_tm LLMs are not messy and random on saturated benchmarks. Just need to wait for SWE to become saturated
