📆 ThursdAI - Oct 2 - SORA 2 the new TikTok? Claude 4.5 disappoints, GLM 4.6, DeepSeek DSA & other...

Quick Overview

OpenAI dominated the AI news cycle with the release of Sora 2, a new video generation model that now includes audio and is integrated into a complete social media app, while Anthropic's Claude 4.5 Sonnet received mixed reviews regarding stability despite strong performance in coding benchmarks, and Deepseek introduced Deepseek V3.2 experimental featuring DSA, which dramatically reduces attention scaling costs.

Key Points: OpenAI released Sora 2, which generates 10-second videos with audio and is integrated into a new iOS social media app, with hosts planning to start an invite chain for listeners. Claude 4.5 Sonnet matched or beat Opus 4.1 on several coding benchmarks (SWEBench verified at 82%) but host Ryan noted regressions in stability, forcing them to consider reverting to Claude 4. Deepseek V3.2 experimental introduced Deepseek Sparse Attention (DSA), resulting in a nearly flat cost curve for context scaling up to 128k tokens, making it nearly five times cheaper than previous versions at that length while maintaining similar benchmark performance (85 on MMLU Pro). OpenAI also launched Pulse, a personalized feed collector agent for Pro subscribers, which Alex called potentially bigger news than Sora due to its utility. GLM 4.6 was released as an advanced agentic flagship model with 200k context, showing near Claude parity, scoring 17.2% on Humanity's Last Exam (without tools), significantly above competitors like Deepseek and Claude 3. CoreWeave, the parent company of Weights & Biases, secured massive infrastructure commitments, including a $22 billion pipeline with OpenAI and an Nvidia backstop guarantee of $6.3 billion. The hosts noted that while open-source models like GLM 4.6 are catching up, closed models like Claude 4.5 Sonnet show significant leaps in agentic capabilities, particularly OS World benchmarks, jumping 16% over Opus 4.1 to 61.4%.

Context: The Thursday AI live show on October 2nd featured hosts Alex Vulov (Weights and Biases/CoreWeave), Wolf from Raven Wolf, Ryan, and LDJ, discussing a flurry of major AI releases from the preceding week. The primary focus centered on OpenAI's latest announcements, particularly Sora 2, contrasted with updates from competitors like Anthropic (Claude 4.5) and advancements in the open-source community, specifically Deepseek's new architectural improvements.
