This week in AI, the dominant theme was the realignment of the entire industry following the US government export controls that suspended access to frontier models like Fable 5 and Mythos 5. This event triggered a rush to fill the vacuum with alternative models, such as Chinese open-weight GLM 5.2 and new model architectures like OpenRouter's Fusion API, highlighting the risk of over-reliance on single AI models.

The US government export controls effectively banned Fable 5 and Mythos 5, leading to a realignment week where businesses and developers sought alternative AI models to reduce dependency risk.
Chinese open-weight model GLM 5.2 became a standout replacement, passing the 'vibe check' and being praised by experts like Jeremy Howard as a frontier model that is 'super fast' and 'not too verbose'.
OpenRouter launched its Fusion API, which claims to deliver Fable-level intelligence at half the price by fanning out prompts to a panel of models with a judge model selecting the best response.
SpaceX's acquisition of Cursor, following its IPO, suggests potential new competition in the AI model space, though its direction between efficiency and state-of-the-art remains unclear.
European leaders at the G7 faced a dilemma, caught between seeking access to suspended models and planning a sovereign AI path.
"GLM 5.2 is a marvel. It is at least as good as Opus 4.8 and GPT-5.5. It's super fast and expensive and not too verbose. It responds with nuance and judgment and handles long context very well. I've never experienced an open weights model like this before."
"For the first time in around three years, it feels like the AI table has been flipped over. Yes, the labs and hyperscalers will have the highest chance of resetting it before everyone else, but there is now a window for a new ecosystem to emerge."
"Folks who are running GLM 5.2, how are you doing it? What harness and provider are you using? Getting FOMO about an open weights model for the first time."
