CM3leon launched on July 18, 2023 with 101 votes, #596 of 4,347 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 3 years on.

What it does

CM3leon (pronounced like "chameleon") is the first multimodal model trained with a recipe adapted from text-only language models. It undergoes a unique two-stage training process for superior performance.

Today, we’re showcasing CM3leon (pronounced like “chameleon”), a single foundation model that does both text-to-image and image-to-text generation.

Interest and research in generative AI models has accelerated in recent months with advancements in natural language processing that lets machines understand and express language, as well as systems that can generate images based on text input. Today, we’re showcasing CM3leon (pronounced like “chameleon”), a single foundation model that does both text-to-image and image-to-text generation. CM3leon is the first multimodal model trained with a recipe adapted from text-only language models, including a large-scale retrieval-augmented pre-training stage and a second multitask supervised fine-tuning (SFT) stage. This recipe is simple, produces a strong model, and also shows that tokenizer-based…from ai.meta.com

    I saw this [0] pretty cool thread by user revskill, and wanted a quicker way to search through it, but also to keep them all in one place so I can read them at my leisure whenever I get time. Right now is like 60 lines of Ruby using Nokogiri, but I will certainly look into it further down the line and improve the list. There's a cronjob checking the thread every 12 hours but I will eventually shut that down and it will become static after that. There are some really awesome blogs in there. I really recommend going through the list, it made my day. [0] "Could you share your personal blog…
