The llama.cpp project now supports vision capabilities, allowing users to incorporate image understanding into their large language models. By leveraging a pre-trained visual question answering (VQA) model and connecting it to the language model, llama.cpp can process both text and image inputs. This is accomplished by encoding images into a feature vector using a model like CLIP, and then feeding this vector to the language model, prompting it with a description of the image's content. This multimodal capability enables applications like generating image captions, answering questions about images, and even editing images based on text instructions.
A Hacker News post describes a method for solving hCaptcha challenges using a multimodal large language model (MLLM). The approach involves feeding the challenge image and prompt text to the MLLM, which then selects the correct images based on its understanding of both the visual and textual information. This technique demonstrates the potential of MLLMs to bypass security measures designed to differentiate humans from bots, raising concerns about the future effectiveness of such CAPTCHA systems.
The Hacker News comments discuss the implications of using LLMs to solve CAPTCHAs, expressing concern about the escalating arms race between CAPTCHA developers and AI solvers. Several commenters highlight the potential for these models to bypass accessibility features intended for visually impaired users, making audio CAPTCHAs vulnerable. Others question the long-term viability of CAPTCHAs as a security measure, suggesting alternative approaches like behavioral biometrics or reputation systems might be necessary. The ethical implications of using powerful AI models for such tasks are also raised, with some worrying about the potential for misuse and the broader impact on online security. A few commenters express skepticism about the claimed accuracy rates, pointing to the difficulty of generalizing performance in real-world scenarios. There's also a discussion about the irony of using AI, a tool intended to enhance human capabilities, to defeat a system designed to distinguish humans from bots.

Several commenters pointed out the significant compute resources still required for training and inference, raising questions about accessibility and environmental impact. Finally, discussions touched upon the ongoing debates surrounding open-sourcing LLMs, safety implications, and the potential for misuse.
Voyage has released Voyage Multimodal 3 (VMM3), a new embedding model capable of processing text, images, and screenshots within a single model. This allows for seamless cross-modal search and comparison, meaning users can query with any modality (text, image, or screenshot) and retrieve results of any other modality. VMM3 boasts improved performance over previous models and specialized embedding spaces tailored for different data types, like website screenshots, leading to more relevant and accurate results. The model aims to enhance various applications, including code search, information retrieval, and multimodal chatbots. Voyage is offering free access to VMM3 via their API and open-sourcing a smaller, less performant version called MiniVMM3 for research and experimentation.
The Hacker News post titled "All-in-one embedding model for interleaved text, images, and screenshots" discussing the Voyage Multimodal 3 model announcement has generated a moderate amount of discussion. Several commenters express interest and cautious optimism about the capabilities of the model, particularly its ability to handle interleaved multimodal data, which is a common scenario in real-world applications.
One commenter highlights the potential usefulness of such a model for documentation and educational materials where text, images, and code snippets are frequently interwoven. They see value in being able to search and analyze these mixed-media documents more effectively. Another echoes this sentiment, pointing out the common problem of having separate search indices for text and images, making comprehensive retrieval difficult. They express hope that a unified embedding model like Voyage Multimodal 3 could address this issue.
Some skepticism is also present. One user questions the practicality of training a single model to handle such diverse data types, suggesting that specialized models might still perform better for individual modalities like text or images.
