Hugging Face announces upskill, a tool to generate agent skills using large models (like Claude Opus 4.5) and transfer them to smaller open models, demonstrated on CUDA kernel writing for diffusers models.
Lovable added Claude Opus 4.5 as a core model for chat mode and code generation, reporting 15% fewer mistakes when making edits, 5% higher project success rate, and noticeably better designs, at no additional cost to users.
Amp is offering a limited-time trial of Claude Opus 4.5 as the main agent in smart mode in its product. The company notes that while the model is cheaper than Opus 4.1, it remains more expensive than Gemini or Claude Sonnet 4.5.
