Description

FLUX.1 Krea [dev] is a cutting-edge, open-source diffusion transformer with 12 billion parameters, developed through the collaboration of Krea and Black Forest Labs, aimed at providing exceptional aesthetic precision and photorealistic outputs while avoiding the common “AI look.” This model is fully integrated into the FLUX.1-dev ecosystem and is built upon a foundational model (flux-dev-raw) that possesses extensive world knowledge. It utilizes a two-phase post-training approach that includes supervised fine-tuning on a carefully selected combination of high-quality and synthetic samples, followed by reinforcement learning driven by human feedback based on preference data to shape its stylistic outputs. Through the innovative use of negative prompts during pre-training, along with custom loss functions designed for classifier-free guidance and specific preference labels, it demonstrates substantial enhancements in quality with fewer than one million examples, achieving these results without the need for elaborate prompts or additional LoRA modules. This approach not only elevates the model's output but also sets a new standard in the field of AI-driven visual generation.

Description

Leanstral 1.5 is a model licensed under Apache-2.0, designed for effective proof engineering in Lean 4, aimed at enhancing the capabilities and accessibility of formal verification. It boasts a total of 119 billion parameters, with 6 billion of them being active, marking a significant improvement in performance for tasks such as theorem proving, agent-based proof engineering, and the verification of practical code. The development of Leanstral 1.5 involved a comprehensive three-stage training process, which included mid-training, supervised fine-tuning, and reinforcement learning utilizing CISPO. In a multiturn environment, the model is tasked with receiving a theorem statement, submitting a proof, and refining its approach based on feedback from the Lean compiler until the proof is either successfully compiled or the available resources are depleted. In the code agent setting, Leanstral functions similarly to a developer navigating a raw filesystem, allowing it to edit files, execute bash commands, and interact with the Lean language server to monitor goals, errors, and type information in real time. This innovative approach not only streamlines the proof engineering process but also significantly enhances the user experience in formal verification tasks.
