What they believe

Frontier language models will remain reasoning models trained with RLVR-style chain-of-thought for the foreseeable future.
GPT-6 Astra (and likely any LLM in the foreseeable future) is still a reasoning model.

Coding something from scratch is one of the best ways to truly understand how it works.
So this one will not be coding-related, but coding from scratch is actually a very, very useful technique because it really helps you understand how something is implemented.

AI text detectors and the LLMs they try to catch are locked in a permanent cat-and-mouse arms race.Their words
AI checkers are essentially a cat-and-mouse game. AI checkers may learn to detect a certain pattern that is indicative of AI-generated content. Then, the next LLM may incidentally or deliberately not exhibit that pattern and avoid detection. The AI checker then has to be updated to detect said LLM, and so forth.

Looped/recurrent-depth transformer architectures can improve model quality at a fixed compute budget when the model is large enough.

Building an AI Text Detector From Scratch Said 15 Aug 2026
The special reasoning-trace delimiter tokens used by reasoning models are cosmetic and not required for good reasoning performance.
These <think> and </think> tags are cosmetic with respect to reasoning ability. They do not make the model reason, and they are not required to achieve good reasoning performance.
Controlling Reasoning Effort in LLMs Said 18 Jul 2026
Raising inference-time reasoning effort on a smaller model can match the performance of a larger model run at lower effort.
a smaller model at a higher reasoning effort can sometimes reach a similar score as a larger model at a lower reasoning effort
Controlling Reasoning Effort in LLMs Said 18 Jul 2026
Pushing an LLM's reasoning budget higher eventually yields diminishing returns and becomes uneconomical.
This saturation can be seen more clearly for the GPT 5.6 Sol model, which also shows that increasing reasoning budgets can become uneconomical at some point.
Controlling Reasoning Effort in LLMs Said 18 Jul 2026
Proprietary AI services will become more restrictive over time, making open-weight alternatives valuable as a backup.
proprietary services may become more restrictive over time, and it's maybe a good idea to be comfortable with open-weight alternatives as a backup.
Using Local Coding Agents Said 27 Jun 2026
When an AI lab builds both a model and a coding harness, the model is optimized for that lab's own harness first.
if an LLM developer also develops a coding harness, it is somewhat safe to assume that their model is optimized for their own harness first
Using Local Coding Agents Said 27 Jun 2026
In coding agents, untrusted repositories should be treated as hostile by default because they can steer the agent into risky actions via approved tools.
untrusted repos should be treated as hostile by default because they can steer the agent toward reading files, running commands, or sending data through approved tools.
Using Local Coding Agents Said 27 Jun 2026
Long-context efficiency has become a central priority in LLM development because agent harnesses require working with increasingly long contexts.
In 2026, long-context efficiency is king as more and more LLMs get plugged into agent harnesses (OpenClaw etc.), which requires working with longer and longer contexts.
LLM Research Papers: The 2026 List (January to May) Said 6 Jun 2026
As reasoning models and agents retain more tokens for longer, KV-cache size and attention cost become the main constraint on scaling context.
As reasoning models and agent workflows keep more tokens around (for longer), KV-cache size, memory traffic, and attention cost quickly become the main constraints, and LLM developers are adding a growing number of architecture tricks to reduce those costs.
Recent Developments in LLM Architectures: KV Sharing, mHC, and Compressed Attention Said 16 May 2026
Larger language models already have enough capacity that extra per-layer embedding tricks add little benefit to them.
However, larger models already have sufficient capacity where these extra embeddings may not help that much.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.

- MiMo-V2.6 is "simply" the best (for now). Despite its simple architecture design it's currently No.1 in the open-weight benchmarks (weighted average). With "simple," I mean a classic Grouped Query Attention (GQA) with Sliding Window Attention (SWA) at a tiny 128-token window size. So, that underlines one of the points I've been trying to make in recent months: most of the progress still comes from the data and post-training recipe improvements. Fancy attention variants are just mostly efficiency tweaks. What are some of the training data improvements and recipe improvements? The MiMo team sha… 22 Sept 2026
- It’s easy to dismiss Jev it as “just a classifier”. But people (me included) who have been training encoder-style models for classification for many years know they were usually special-purpose and limited in some way. The breakthrough of Jev is that it generalizes well. And I’d say the secret sauce is probably more in the data than in the training algorithm. (Plus a nice API design on top of it.) 20 Sept 2026

The task here was to recreate the image in the center using the Paint UI. Super interesting how the two different LLMs+Harnesses approached this totally differently by default. I.e., Astra tried to approach this by drawing and layering geometric shapes. Qwen approached this pixel by pixel. (Of course, the pixel-by-pixel result looks closer to the original, it's essentially a low-res version of that by nature.) So, the Qwen-generated image would surely… 15 Sept 2026
- Since I had to discuss the "pacing" with a lot of people this weekend, here are my two cents: I don't think pacing literally means that these companies will be "slowing down" training and development in any way. "Pacing" here means adding a framework for more checks. We have seen some of that "pacing" already in recent months, when Mythos wasn't released as-is but instead a delayed, nerfed Fable variant was released. Or when Astra wasn't released right away / there is an existing Astra model that hasn't been released yet. These Mythos/Fable and Astra pacing decisions were ad hoc. If you are a… 14 Sept 2026
