Summary
This video is a tech news roundup produced and narrated by the YouTube channel AI Revolution. It covers four major AI developments: the accidental leak of Anthropic’s next-tier model Claude Mythos (also codenamed Capybara), Meta FAIR’s brain-response foundation model TRIBE v2, the openJiuwen community’s task-executing agent JiuwenClaw, and Alibaba’s RISC-V-based XuanTie C950 agentic AI chip.
What is shown
- [00:03] Title cards and preview graphics highlighting Anthropic’s leaked Claude Mythos, Meta’s TRIBE v2, JiuwenClaw, and Alibaba’s RISC-V chip.
- [00:39] Screenshots of the leaked Anthropic research preview draft for Claude Mythos / Claude Capybara dated March 2026, including text explaining the new tier above Opus and its cybersecurity preview testing.
- [00:53] Mentions and mockups of Claude Cowork and social media posts on X discussing the leak before Anthropic took it down.
- [02:51] Reference to a BBC headline regarding a Chinese state-linked group targeting ~30 organizations with automated attacks using Claude Code.
- [03:36] Fortune headline regarding an unreleased model and an invite-only Anthropic CEO retreat in the UK.
- [04:05] Presentation of Meta FAIR’s research paper and interactive demo interface for TRIBE v2, showing simulated 3D cortical activations side-by-side with video stimuli.
- [05:04] Diagrams of TRIBE v2’s three-stage multimodal architecture (Llama 3.2-3B, V-JEPA2-Giant, Wav2Vec-BERT 2.0 feeding into a Transformer).
- [08:16] Overview slides and text excerpts introducing the openJiuwen community's JiuwenClaw agent, detailing its three-layer memory model and "Context Slimming" feature.
- [10:39] Media reporting (CNBC, South China Morning Post) and chip graphics introducing Alibaba T-Head's XuanTie C950 RISC-V processor for data center agent inference.
Claims & numbers
- Anthropic Claude Mythos:
- The presenter states nearly 3,000 assets (images, PDFs, CMS configurations, internal documents) were accidentally left accessible in a public cache.
- The model sits above Claude Opus as a new model class, described internally as a "step change" in performance, but is very compute-intensive and costly to serve.
- Anthropic reportedly restricted release to a small group of early-access cybersecurity defenders because of risks of autonomous exploitation.
- Meta TRIBE v2:
- The model was trained on 451.6 hours of fMRI data from 25 individuals across movies, podcasts, and silent videos, and evaluated on 1,117.7 hours from 720 people.
- Predicts neural activity across 20,484 cortical vertices and 8,802 subcortical voxels across a 100-second context window.
- Achieved a group correlation near 0.4 on the Human Connectome Project 7T dataset, described as roughly twice as good as the median subject's group-predictivity.
- Fine-tuning for one epoch on up to 1 hour of subject data reportedly outperformed linear models by 2x to 4x.
- JiuwenClaw:
- Features a three-layer memory architecture (Stable Identity, Long-term Background, Dynamic Trajectory) and context slimming to prevent context drift and token explosion.
- Natively integrates with Huawei Celia (Xiao Yi), Telegram, WhatsApp, Feishu (Lark), and Web, supporting private enterprise deployment.
- Alibaba XuanTie C950:
- Built on the open-source RISC-V architecture specifically targeting data center agentic AI inference and multi-step workloads.
- Alibaba claims over a 30% performance improvement compared to some mainstream products due to workload-specific architectural customization.
Notable quotes
- [01:58] "The company said the model represents 'a step change' in performance and is 'the most capable we've built to date.'"
- [02:20] "Although Mythos is currently far ahead of any other AI model in cyber capabilities, it presages an upcoming wave of models that can exploit vulnerabilities in ways that far outpace the efforts of defenders."
- [04:26] "For years, neuroscience has mostly studied the brain in pieces... what Meta is trying to do with TRIBE v2 is build one system that can look across video, audio, and language together..."
