MISTRAL CEO CONFIRMS ‘LEAK’ OF NEW OPEN SOURCE AI MODEL NEARING GPT-4 PERFORMANCE

The AI community is abuzz with a leaked large language model called "miqu-1-70b" that was shared on HuggingFace and 4chan. The model shows performance rivaling OpenAI's GPT-4 and is linked to Mistral's Mixtral 8x7b. This incident, acknowledged by Mistral's CEO as a leak by an enthusiastic customer, highlights the growing capabilities of open source AI.

MICROSOFT LASERS AWAY LLM INACCURACIES

Dipendra Misra presented Layer-Selective Rank Reduction (LASER), a technique that improves large language model (LLM) accuracy by replacing a weight matrix with a smaller approximation, at the January Microsoft Research Forum.

LLAVA 1.6

The newest version of Llava, a vision language model, has improved OCR, reasoning, and world knowledge. It matches Gemini on some tasks. The Llava team plans to release data, code, and the model.

WEAVER: FOUNDATION MODEL FOR STORY TELLING

Weaver is a series of models specifically trained to tell stories. The largest model (34B params) outperforms GPT-4 on a storytelling benchmark.

TEXT-BASED IMAGE INPAINTING

This paper introduces a benchmark and two datasets for scene and handwritten texts. Featuring original, corrupted, and assistant images, the novel Global Structure-guided Diffusion Model (GSDM) leverages text structure to efficiently recover clean texts. It shows significant improvements in recognition accuracy and image quality.

LONG VIDEO UNDERSTANDING WITH OPTIMAL TRANSPORT

Norton is a new approach to improving long-term video understanding by addressing the multi-granularity noisy correspondence issue in video-language studies.

LIDAR-BASED MOVING OBJECT SEGMENTATION FOR AUTONOMOUS DRIVING

MF-MOS is a new model for better detecting moving objects in autonomous driving using LiDAR technology. It uniquely separates motion and semantic information, using residual maps for motion capture and range images for semantic guidance.

MCTS IMPLEMENTATION IN JAX

Monte Carlo Tree Search (MCTS) is a state-of-the-art search algorithm. It was used in AlphaGo and researchers are now working to integrate it with language models. MCTS is notoriously tricky to implement.

WHAT CAN BE DONE IN 59 SECONDS

AI has gotten good enough to accomplish multiple tasks in under a minute, which means organizations and employees are going to have to emphasize using AI for good, not bad.

COMMERCIALLY LICENSED LLAVA MODEL

FireLlava is a new open vision model trained on data that makes it possible to use for commercial tasks. It matches the performance of the original Llava, but not yet to the level of Llava 1.5.

SERVICENOW’S STATEMENT ON AI

ServiceNow, a $150b market cap company, last week announced that its gen AI products drove the largest net new ACV contribution for its first full quarter of any of its new product family releases ever, including its original Pro SKU. We’re already seeing enterprise-level AI applications drive meaningful revenue growth – that’s cool.
