Tessera: A Temporal Foundation Model for Earth Observation
with Sadiq Jaffer and Frank Feng
Last week Frank Feng and I joined Robin Cole on his satellite image deep learning podcast to talk about Tessera: how it works, how it differs from existing models, and our future plans. Thanks for hosting us, Robin!

Earth Observation on a Budget: Finding Solar Farms with a 42k-Parameter Model
- Sadiq Jaffer
It still surprises me you can get good performance with even tiny models on top of TESSERA embeddings. Here's how to find solar farms in the UK with a small ~42k CNN: toao.com/blog/earth-o...

Three Steps for OCaml to Crest the AI Humps
- Sadiq Jaffer
There's relatively little LLM training data for niche languages and this causes poorer coding agent performance. I think this is an existential threat for smaller language communities like OCaml.
My talk at the OCaml workshop gave some actionable steps to mitigate that: toao.com/blog/ai-exis...

The most incredibly fun part of this Nature comment on evidence synthesis we published today is that the cartoonist (David Parkins) also did Beano and Dennis the Menace (!) A true legend. www.nature.com/articles/d41...

The rapid rise in AI-generated fraudulent academic papers is "poisoning" scientific literature, say Cambridge researchers in Nature magazine today. But though AI is the problem, it could also help in ensuring the integrity of scientific discovery... buff.ly/AuSNcGd

I'm pleased to announce OxCaml!
OxCaml is Jane Street's branch of OCaml. We've given it a new name and a snazzy logo, and done a bunch of work to make it easy for people to try.

One thing I probably should highlight more in the post is that the proprietary models (like Claude and Gemini) that most students currently have access to can already ace the assignments.

This is a thorny question and mostly comes down to what we're trying to teach. I wonder if a progressive approach where at early stages of teaching there is no automatic tooling but as critical skills are learnt more can be automated. It's a bit of a moving target at the moment though.

Qwen3 Leads the Pack: Evaluating how Local LLMs tackle First Year CS OCaml exercises
- Sadiq Jaffer
Just how good are locally hostable code models on Cambridge first year OCaml assignments? @anil.recoil.org , @jon.recoil.org and I wanted to find out, so ran some tests. TL;DR Qwen3 means we might need new assignments. toao.com/blog/ocaml-l...

New preprint from our work on using LLMs to accelerate conservation evidence synthesis across millions of papers. We crosscheck 3 retrieval strategies against 10 LLMs and benchmark against human experts and find quite a bit of variance https://www.researchsquare.com/article/rs-5409185/v1
