Well, it turns out Dynamic workflows in Opus 4.8 can burn 7.7m tokens in 53m. Definitely something to use sparingly!

This article misunderstands how you can effectively use LLMs for academic writing. The error is common among my colleagues. I teach my students to write using LLM+RAG and writing style prompts. scholarlykitchen.sspnet.org/2025/03/11/g.... Comment is in the image
The author misunderstands how LLMs can be useful in writing articles. Using LLMs without using RAG is just relying on the patterns learned in the training of the model. If you know the relevant literature, using RAG, it fetches the relevant info from the papers you give it, adds it to the prompt and generates a response based on the relevant retrieved information. This addresses issues with hallucinations, cut off dates and citations. Tools like ChatGPTs Deep Research, and The-Literature add search to the beginning of this process.

My students know that if want an essay out of an LLM, upload the PDFs of the papers in the reading list, the assessment guidance and the marking criteria. If they are using notebookLM, they could listen to a chatty podcast, or chat to the podcast in interactive mode to give them ideas for prompts.If you can’t train your students to do better than LLMs plus RAG, then their graduate jobs aren’t going to be around for long. Pretending LLMs fed with the relevant literature and trained in a academic writing style (like notebookLM is trained to generate output in a podcast style) is to bury your head in the sand. Knowledge work is going to change and we have to prepare ourselves and our students for what’s coming. If Google trained a LLM on all the lectures that were captured over the pandemic, they could have create an automatic lecture generator, that fed with relevant papers could generate a lecture. It’s so obvious someone will. Like Uber drivers are really training the driving model that will replace them, all our open papers and lectures, not to mention all our feedback on Turnitin, are training the models that will replace us if we can’t to do more than just regurgitate knowledge. This article doesn’t illuminate the work we’ve got ahead of us

Challenged myself to write a single prompt for gpt4o that makes a game - came up with this after lots of iteration - now got a challenge going at work - who can make the best game from a single prompt (prompt in the alt text) #gamefromaprompt
Create an Asteroids-style game where I control a spaceship that moves with the arrow keys and fires lasers with the space bar. The game should start with multiple asteroids that move randomly across the screen. When a laser hits an asteroid, the asteroid should explode into two smaller asteroids if it's large enough, or disappear if it's small. If asteroids collide with each other, they should also shatter into smaller pieces. Additionally, if an asteroid collides with the spaceship, the game should end. When all asteroids are cleared, a new wave should appear, increasing the number of asteroids by one in each new wave. Also, add a score counter that increases when I destroy asteroids. Provide the full game as an HTML file with a link so that I can download and run in my browser, with all JavaScript included in the HTML file itself.

Bit of a write up in @digitalhealth2.bsky.social of my @healthfoundation.bsky.social remarks on the need for proper evaluation of AI models in health www.digitalhealth.net/2025/02/ai-c...
Shah also called for robust evaluation of AI products to screen out the “snake oil” and “grifters” which he said were inevitable in a lucrative market.

“How do we know that somebody is not just relabelling a simple algorithm as AI, which has certainly been happening, or that the products are just not very good, as you’ve seen from multiple apps on medical and app stores?

“The trouble is it’s just very hard to get independently verified evidence in the space.

“You have a mixture of hyped press releases from the companies themselves, and, on the other hand, newspapers laying into the faults that you’ve seen in particular models, but it’s very hard to get a kind of actual, genuine evidence base,” he said.

thelancet.com
SPIRIT-DEFINE explanation and elaboration: recommendations for enhancing quality and impact of early phase dose-finding clinical trials protocols
Transparent and accurate reporting in early phase dose-finding (EPDF) clinical trials is crucial for informing subsequent larger trials. The SPIRIT statement, designed for trial protocol content, does not adequately cover the distinctive features of EPDF trials. Recent findings indicate that the protocol contents in past EPDF trials frequently lacked completeness and clarity. To address this gap, the international consensus-driven SPIRIT-DEFINE checklist was developed through a robust methodological framework for guideline development, with the aim to improve completeness and clarity in EPDF trial protocols.
