This may be very old man of me, but I feel like there is something about the bluesky algorithm/my feed that is not sucking me in enough. I know, I know, it's sort of the point but still, I need to have some pull to check out the content and it isn't quite itching that scratch.

What a really interesting conversation between two of my favourite people in AI in the form of @karpathy.bsky.social and @dwarkesh.bsky.social. I wish more ppl in this space took the same approach in terms of being open to debate, challenge and overall being humble.

So theoretically LLMs can be deterministic if we set their temperature to zero, but in practice they aren't. This comes down to how we do calculations such as matrix multiplication at inference time. It turns out the order you do these calculations in does matter. (1/6)

Does anyone have cool (or boring) agentic use-cases that they've read about or used?
Doing some horizon scanning work to see what's out there but thought my bluesky network might have ideas!

This was a fun ML problem to tackle, underlined some of the data quality issues with EPCs (92% of the storey count field was missing) 😅.
Think the conclusion around the distinct heating strategies needed for areas with different rise types is definitely a salient one!

Favourite feature from the GPT-5 release is being able to quickly spin out different UIs (which can be previewed), make easy edits without needing to manually edit JS code myself. It's pretty good at instruction following now too!

Brilliant news and about time!
The biggest nuclear programme in a generation will “get Britain off the fossil fuel rollercoaster”, the energy secretary, Ed Miliband, has said, announcing £14.2bn to build a new nuclear power station and a drive to build small modular reactors.

Love this plot of ASHP vs GSHP in terms of their COPs. Really nice illustration of the outdoor temperature dependency of ASHPs vs that of GSHPs (or lack thereof). Observed performance has been interpolated, but based off 2 years of sensor data for a sample size of 883 ASHPs and 124 GHSPs resp. (1/2)

So...many scenarios in which top tech people are predicting AGI within 5 years. Demis Hassabis thinking it'll be just after 2030, and I just can't help but think about how crazy the next 5 years are going to be if these predictions are anywhere close to the mark..

Really cool work done by my colleagues at @nestauk.bsky.social where they use AI to scan for innovation trends/signals. This first edition of Mission radar is on low carbon heating! Check it out.

OpenAI have released a few new models (gpt-4.1, gpt-4.1-mini and gpt-4.1-nano) for their api. I was watching their live release as we've got an application which uses their previous model and wondering about the jump in performance. I'm still guessing based on this plot, where are the values??? 😅

Does anyone find it annoying that Google are force feeding us Gemini in every search. I used to quote that a ChatGPT query was worth 5 google searches in terms of energy. It's now much more accurate to say it's worth 5/6ths of a search. Same goes for Meta's AI feature in WhatsApp. Very in your face.
