Youāll Love This ā ChatGPT Finally Stopped Spamming Em-Dashes
Quick Summary
OpenAI CEO Sam Altman announced via X that ChatGPT will now respect custom instructions to avoid using em-dashes. The change is being called a āsmall-but-happy winā by Altman.
Key Insights
The em-dash has become a visible ātellā of AI-generated text, due to its frequent use by ChatGPT and similar models.
ChatGPTās custom instructions now include punctuation directivesāusers can tell it not to use em-dashes, and it will comply.
The update highlights how much effort is still required to refine AI writing behaviourāeven for something as basic as punctuation.
Why Itās Relevant
If you use AI tools for content, this matters: formatting and punctuation are important for readability and perceived authenticity. For writers, editors and SEO specialists (like you, Tom), the ability to steer stylistic traits means fewer āAI-tellsā in your output and better alignment with your brand voice. Also, it signals that AI vendors are focused not just on ābig leapsā (like AGI) but on refining small but meaningful user-experience details.

Youāll Gain AI-Skills: Rwanda Launches Claude-Powered Learning
Quick Summary
Anthropic is teaming up with the Rwanda government and ALX to deploy the AI learning companion ā Chidi ā across African education systems. The initiative aims to train thousands of teachers and reach hundreds of thousands of learners.
Key Insights
Rwanda will train up to 2,000 teachers and civil servants to integrate Claude-based tools into classrooms.
Learners will access Chidi via ALX programmes, helping them build skills like data analytics and cloud computing.
Since rollout, the tool logged over 1,100 learner conversations and nearly 4,000 sessions, with 9 in 10 users reporting positive experiences.
The partnership supports Rwandaās āVision 2050ā to develop an AI-ready workforce and knowledge economy.
Why Itās Relevant
For you, this is a major case study in how AI meets education at scale ā useful for writing about AI deployments, workforce readiness, and emerging markets. The initiative shows how public-private partnerships can push AI literacy in regions with fast-growing digital economies. Plus, it may influence how AI for education is marketed, adopted and localized globally ā good material for SEO angles in your research and articles.

You Get Clarity ā OpenAI Builds Traceable Neural Logic

Quick Summary
OpenAI trained new āsparseā neural networks where most weights are forced to zero, producing clearer, smaller circuits that can be mechanistically interpreted. They show that increasing sparsity and model size improves interpretability without losing the learning ability.
Key Insights
Dense neural networks are hard to understand because each neuron connects to thousands of others.
By forcing most weights to zero (i.e., sparsifying the connections), OpenAI created models with ādisentangled circuitsā that perform defined tasks and are traceable.
On test algorithmic tasks, sparse models required up to ~16Ć fewer neurons/circuits to perform the same loss as dense models.
Though promising, the approach currently works on smaller models and simple tasks; scaling to frontier-models remains a challenge.
Why Itās Relevant
For you who write about AI, this is a critical shift: the focus is moving from bigger models to models we can understand. That matters for editorial credibility (you can explain how models work, not just what they do), for safety/regulation (transparent models are easier to audit) and for SEO content (interpretability is a growing trend). Also, if you cover AI tools or workflows, this gives a strong story angle: transparent AI = trust = adoption.

1. Google DeepMind: Hurricane Forecasting
DeepMindās new weather-AI predicts hurricane intensity faster and more accurately than traditional systems. During Hurricane Melissa, it identified rapid intensification earlier, giving responders more time. The model needs less compute, delivers quicker forecasts and could reshape global disaster-preparedness. Concerns remain about limited interpretability.
