Two editor’s notes to start. First, we released our OLMo 2 1B model last week and it’s competitive with Gemmas and Llamas of comparable size — I wrote some reflections on training it here. Second, my Qwen 3 post had an important factual error — Qwen actually did not release the base models for their 32B and large MoE model. This has important ramifications for research. Onto the update.

As GPT-4.5 was being released, the first material the public got access to was OpenAI’s system card for the model that details some capability evaluations and mostly safety estimates. Before the live stream and official blog post, we knew things were going to be weird because of this line:GPT-4.5 is not a frontier model. The updated system card in the launch blog post does not have this.
