This is cool. But why don't people know how to pour coffee? www.biorxiv.org/content/10.6... the paper asks how to pour a coffee and the answer is "not like this!"

And all of this, is better with better “training“ goals. Wherever truth is defined, push towards this truth (D). And where it is not defined, use LLMs to check answers ("self evaluation", (E))

A third idea (C) for making answers, combine many components into "Agents", : coordinate component large language models (LLMs), memory, databases, and tools

Konrad Kording @kordinglab.bsky.social · 25/08/2026
A second idea (B) for making answers, tool use. Call programs like databases, internet search, calculators etc.

A first idea (A) for making answers, inner speech. Produce words that are just like a scratchpad which the user never sees.

Konrad Kording @kordinglab.bsky.social · 25/08/2026
The thing that makes Neural networks so powerful is that there is a direct way (4) of improving them with examples and towards any definition of answer quality (training).

Konrad Kording @kordinglab.bsky.social · 25/08/2026
The real work is done by a core machine, the neural network which is used to generate one word at a time based on its inputs. The probability of each word depends on prior words. And words are chosen one by one according to those probabilities.

Konrad Kording @kordinglab.bsky.social · 25/08/2026
All that LLMs do is convert prompt words into answer words (1). And the old recipe does that with two goals, language imitation (2) and people's rating of answer quality (3). Answers are produced word by word using a neural network.

Konrad Kording @kordinglab.bsky.social · 25/08/2026
We will use everyday language where possible and mark technical terms in purple. Key is that modern LLMs have a component of making answers (in blue, called "inference") and a component of improving answers (red, called "training").

Thread. I have yet to see a proper explanation of how LLMs actually work that is targeted to an informed general audience. So here is an explainer that I put together along with Tim @countzerozzz (inspired by @CIFAR_News LMB discussions).

Here is the preregistration. Missing: Primary outcome; exact ROI definitions; model family; interaction term; prediction direction; preprocessing/exclusions; multiple-testing correction; classifier plan; confirmatory vs exploratory hierarchy.

A useful feature that, I think, all reference managers should provide - every (AI selected) relevant paper comes with a summary of how it matters to the project at hand (AI generated). Check it in planyourscience.com

Konrad Kording @kordinglab.bsky.social · 04/05/2026
Ok. Then this aspect of word-use is the only thing leading to the disagreement, it would seem. How do you fit your use to the Merriam Webster definition?

My app that helps students think more carefully through their projects now looks really pretty by 2026 standards (imho). Try it out at planyourscience.com

From my talk in italy last summer (Neuroscience in data deluge age): docs.google.com/presentation... --- would be super curious on you two's general take on this

Here are the most popular neuromodulators (made you a new github repo): github.com/koerding/neu...

Konrad Kording @kordinglab.bsky.social · 28/04/2026
After rereading the cool hidden brain paper (www.frontiersin.org/journals/sys...) I decided to make a new version. Code and everything available here: github.com/koerding/neu... Most popular: hippocampus. Why are diagonal band, medial geniculate nucleus, and interposed nucleus so unpopular?

Others believe having the right amount of micro data would enable better AI. Or simulations of whole nervous systems. While everyone has their own goals, the value of compilers would help everyone.
100
Konrad Kording @kordinglab.bsky.social · 31/03/2026
What would it enable? Entirely depends on whom you ask. Single cell modeling needs parameters, which we currently can't measure. Many physiology questions require micro-parameters. Many disease related questions require micro-data.

Konrad Kording @kordinglab.bsky.social · 31/03/2026
For now there is a wide gulf between imaging giving us structure and physiology giving us function. We argue that we need to build a compiler that translates the former into the latter.
110
Konrad Kording @kordinglab.bsky.social · 31/03/2026
The time is ripe for compilers because imaging is getting better and cheaper at an unbelievable speed - voxels per dollars is doubling every roughly 1.5 year, at rapidly improving quality. 3d-imaging becomes attractive for neuroscience.

Konrad Kording @kordinglab.bsky.social · 31/03/2026
Preprint out arguing that we should build the techology to translate (compile) molecularly annotated connectomes into dynamics. I think this is incredibly important. arxiv.org/abs/2603.25713

Wow. LLMs are starting to self-reflect on being LLMs doing pattern matching. From a discussion about one of my papers:

Planyourscience.com now applauds the good changes you make - and pushes back on the less good one.

Substack makes it super easy to test different titles against one another. I experimented for a while. I did learn something through testing with a range of titles over a few months. Whoever reads my substack posts does not care one bit what my posts are titled as.
Two titles. One gets 27.3 and the other 27.7 open rate.

Konrad Kording @kordinglab.bsky.social · 27/12/2025
I think this was not very good LLM probing. See the screeenshots of me trying to help. Do you see how I think you could get dramatically more mileage out of LLMs by probing better?

In any case, this is me trying to provide Konrad style mentoring as an app. It won't be perfect. It is far too ambitious. Open to collaboration on this. However, it is not open source and won't be. Why not? Automating (even parts) of science could open doors to junk.

If you have already started a project (e.g. written an abstract) or you want to see how a given project should have been planned you can import from files:
110
Konrad Kording @kordinglab.bsky.social · 20/11/2025
Obviously, science is collaborative. So you can share your project with someone else and edit it jointly in real time, google docs style.

Konrad Kording @kordinglab.bsky.social · 20/11/2025
To give better feedback/ chat experience, the app also knows you if you give it your @orcid.org . Planning science avoids wasted time, enshrines scientific rigor, leads to better papers. And makes science more fun.

Konrad Kording @kordinglab.bsky.social · 20/11/2025
When asking for feedback, the app obtains literature and insights from Semantic Scholar, Open Alex, and Consensus NLP - this far improves AI performance at knowing the literature:

Konrad Kording @kordinglab.bsky.social · 20/11/2025
It is an important skill to learn how to write papers. But there are also a lot of standards for writing. So the app exports as outlines/ papers/ todo lists.
110
Konrad Kording @kordinglab.bsky.social · 20/11/2025
For unconstrained questions/ brainstorming there is a chat that has detailed knowledge of the process and the project and helps in planning (and will eventually propose changes to the plan):

Konrad Kording @kordinglab.bsky.social · 20/11/2025
AI provides feedback based on extensive criteria designed for the app (also shout out to @gunnarblohm.bsky.social and Brett Mensh for feedback for me writing this). This feedback aims to help improve a concrete part of the project. Very constrained:

Konrad Kording @kordinglab.bsky.social · 20/11/2025
The user interface is designed to make it easy to enter the relevant information - it has full templates for most science use cases. It also automatically saves on a database and has professional grade login via orcid, google, or github.

Konrad Kording @kordinglab.bsky.social · 20/11/2025
I think almost all scientific projects should be planned carefully. And I think an app can dramatically improve that. So I wrote an app for that (free for now, if you can fund this let me know). I tested it quite a bit (>8000 users in beta so far). try it: planyourscience.com

AI is growing exponentially at a timescale of months while the economy is growing at a timescale of decades. How should we model the economy with rapidly increasing intelligence tech and slowly increasing physical tech? New AI+econ paper.

Its a new term and a lot of us are preparing their lectures. I am a huge fan of online ways of teaching. And my student Joey Rudoler @jrudoler.bsky.social made a great online stats course. Shiny app and all. Modern take on stats. Thought some of you may appreciate.

Every generation has been richer for a long time and, yet, people feel we live in worse times than the past. Are you all believing the future will tank? Mostly because of AI? Difference academia vs industry? Are my friends just drawn non-randomly?

Apparently people appreciate highly focused talks. I will do my best to comply in the future. 1 talk, 1 idea it is. Its a bit hard for us older folks as we probably have accumulated many ideas.
How many ideas should a scientific talk be about? 1 (56%), 3 (30%) As many as possible (10%).

Wow. Twitter is a lot more concerned about neuroscience than me!
most people believe most papers do not contribute.

The transmitter post on embracing complexity in brains (through AI) just came out. I love embracing complexity. But I fear we have not yet figured out what we should do in this new complex space.
