Meta<\/strong> has unveiled Chameleon<\/strong>, its new multimodal artificial intelligence designed to tackle the growing competition in the field of generative AI. Chameleon stands out for being natively multimodal<\/strong>, seamlessly integrating components from different modalities such as images, text, and code<\/strong>.<\/p>\n\n\n

According to the paper<\/a> published by the research team, Chameleon’s architecture allows for outstanding performance in tasks that require a deep understanding<\/strong> of both visual and textual information. Among Chameleon’s notable capabilities are image captioning and visual question answering (VQA), as well as its competitiveness in exclusively textual tasks<\/strong>.<\/p>\n\n\n\n

Traditionally, multimodal models are created through a process known as “late fusion”<\/strong>, where the AI system processes different modalities separately and then merges the encodings for inference. However, this approach limits the ability of models to seamlessly integrate information across different modalities<\/strong>.<\/p>\n\n\n\n

Chameleon has adopted an architecture of “early fusion based on mixed tokens”<\/strong>, which means that it has been designed from scratch to learn from an interleaved mixture of images, text, and other modalities<\/strong>. This methodology transforms images into discrete tokens, similar to how language models handle words, and uses a unified vocabulary of text, code, and image tokens.<\/p>\n\n\n\n

Compared to similar models like Google Gemini<\/a><\/strong>, Chameleon offers a more cohesive integration of modalities during content generation<\/strong>, as it does not require specific components for each modality.<\/p>\n\n\n

The Chameleon training was carried out in two stages, using a vast dataset that includes 4.4 trillion text tokens<\/strong>, image-text pairs, and interleaved text and image sequences. The Chameleon models, with 7,000 and 34,000 billion parameters<\/a><\/strong>, were trained for over 5 million hours on 80 GB Nvidia A100 GPUs.<\/p>\n\n\n\n

The experiments showed that Chameleon can perform a wide range of text and multimodal tasks with market-leading performance. In VQA and image captioning tests, Chameleon-34B outperformed models like Flamingo, IDEFICS, and Llava-1.5<\/strong>. Additionally, it matched the performance of other models with fewer training examples<\/strong> in context and with smaller models.<\/p>\n\n\n\n

Despite the complexity of multimodality, Chameleon remains competitive in text-only tasks, comparable to models like Mixtral 8x7B and Gemini-Pro in logical reasoning and reading comprehension tests<\/strong>. Researchers highlight that Chameleon unlocks new multimodal reasoning and generation capabilities, offering user-preferred results in documents that combine text and images in an interleaved manner.<\/p>\n\n\n
