Shortwave
What is Shortwave?
Shortwave is an AI email client built by former Google engineers that wraps Gmail with inbox organization tools and an agent you can prompt to search, write, schedule, and filter mail. It runs on iOS, Android, Mac, and Windows and syncs with Gmail accounts. The app positions itself as a spiritual successor to Google Inbox, with bundles, splits, and keyboard shortcuts at the center of daily triage.
Most Gmail add-ons bolt on one feature. Shortwave treats the whole inbox as a workflow surface: you triage with bundles and todos first, then ask the agent to draft replies, run natural language search across years of mail, or spin up filters written in plain English. That combo of Inbox-style organization plus a prompt-driven assistant sets it apart from Superhuman-style speed clients and basic AI summarizers.
Sales reps, founders, and support leads use it to split high-priority threads, track read receipts, and share live threads with teammates without pasting screenshots into Slack. Teams on Gmail who miss Inbox bundles or want calendar-aware scheduling from inside mail tend to stick with it once they adopt the Shortwave Method triage flow.
CM3leon
What is CM3leon?
CM3leon is a multimodal foundation model from Meta AI, introduced in July 2023 on ai.meta.com. Pronounced like "chameleon," it combines text-to-image and image-to-text generation in one architecture instead of separate specialized models.
Meta trained CM3leon with a recipe adapted from text-only language models: large-scale retrieval-augmented pre-training followed by multitask supervised fine-tuning. The causal masked mixed-modal (CM3) design lets the model generate sequences of text and images conditioned on mixed image and text inputs, expanding beyond earlier models that handled only one direction.
On the MS-COCO text-to-image benchmark, CM3leon reported a zero-shot FID score of 4.88 while using five times less compute than prior transformer-based text-to-image methods. Meta positions it for researchers and teams working on unified vision-language generation, editing, captioning, and visual question answering.
