a summary:We offer multimedia linguistic models with Apple intelligent via Apple devices and services: IA 3B-Parameter model on the Apple improved device through architectural innovations such as CV-CACHH and training on a 2-bit quantity; The II is a developed server model based on the PT-MOE transformer, the new parallel mix that combines parallel, the branching account of experts, and the intertwined global local interest to provide high quality with a competitive cost on the Apple Special Cloud Calculation platform. Both models are trained in multi -language and multi -media data sets widely by crawling on the responsible web, licensed companies, and high -quality synthetic data, then they are more improved with learning subject to supervision and reinforcement on a new simultaneous platform. The resulting models support several additional languages while understanding images and implementing tool calls. In general standards and human assessments, both the server model and the device model correspond to or bypass open -sized foundation lines.

The new basis framework centered around Swift Generation Generation, inviting restricted tools, and setting a Lora transformer, allows developers to integrate these capabilities with a few lines of software instructions. The latest developments in Apple’s intelligence models are based in our responsible approach to artificial intelligence with guarantees such as filtering content and evaluation of the sites, in addition to our commitment to protecting the privacy of our users through innovations such as Cloud Compute.
