Flower Labs introduced Endeavor 1.1, its third model release this year after Lizzy and Endeavor 1.0. Flower reports gains over 1.0 on GPQA (92.0 to 94.4) and HumanEval (98.2 to 99.9). Endeavor 1.1 also adds image input. It can be deployed as a Flower-managed service, in a private cloud, or on premises, with a new option for inference on GPUs located in the EU. Customers can read the model's thinking traces and keep its outputs and traces to train their own models. Access is by request, and the benchmark comparisons are Flower's own.
