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.
Parsio

What is Parsio?
Parsio is an email assistant that turns incoming messages and attached documents into structured data you can export to spreadsheets or automation tools. It routes each file through one of four parser engines: template rules, AI extraction, GPT parsing, or OCR for scanned PDFs.
Where basic email parsers rely on brittle regex, Parsio lets you pick the engine that matches the document. Template mode handles fixed layouts like invoices, while GPT parsing covers changing formats, and the AI parser auto-extracts 15+ common document types including bank statements and receipts.
Operations teams, bookkeepers, and RevOps leads use Parsio to pull fields from vendor emails, bank alerts, and PDF attachments into Google Sheets, Zapier, Make, n8n, or webhooks. Credit-based pricing starts free at 30 parses per month.
