xAI's Grok Bot introduced Data Bot, a Shared Bot built by the data science team at SpaceXSI that lets any employee query the data warehouse, run analyses, and get results without waiting for a data scientist. It learns from shared memory, adapts output formats to individual preferences, and can join Slack channels to post proactive updates. Last week alone, Data Bot handled an estimated 70 hours of work that would otherwise have fallen on the data team.

Anthropic has launched Message Threads in public beta for its Claude Messages API, allowing long-running agents to send only new messages each turn instead of resending the full conversation history. For sessions with 500,000 to 1 million tokens, median time to first token drops by about 35%. Threads are held encrypted in memory and expire after five minutes of inactivity. The feature is available on Claude Platform, AWS, Microsoft Foundry, and Google Cloud at standard token rates.

OpenAI has launched the Grid Protectors Program, a national initiative to help its future AI compute campuses reduce electricity demand when the US grid is under strain. Working with utilities, regulators, and policymakers, OpenAI will design facilities to cut power use during peak periods. A pilot agreement with Georgia Power at the planned Effingham County campus includes up to 1,000 megawatts of flexible demand response, enough to power roughly 700,000 households, with Georgia Power projecting approximately $950 million in annual customer savings beginning in 2029.

Israeli startup 42AI has exited stealth with $62.5 million in seed funding to build a behavioral world model that predicts human decisions. The transformer-based system converts observations of user behavior into mathematical trait representations, then calculates decision probabilities under various conditions. Currently deployed at 10 large financial brokerages, it helps manage liquidity, margin requirements, and hedging exposure. The company claims 98% accuracy in predicting trading flows and an F1 score of 0.8–0.85, and says one brokerage generated $30 million in additional value through dynamic hedging.

Elon Musk confirmed that SpaceX cut Grok Bot usage limits after costs became unsustainably high relative to revenue. Over Halloween weekend, some users found their weekly limits maxed out despite not using the agentic AI overnight, with usage jumping from as low as 50% to 100%. Musk acknowledged the issue in an X reply but has not addressed it on his main feed. SpaceX's Super Intelligence division turned a $431 million profit, though $1.2 billion in one-time costs from its Cursor acquisition reduced gains.

Hume AI has launched its Audio Decision API, an audio-native model that answers custom questions about speech and sound in real time. Unlike transcript-based systems, it processes raw audio directly, returning structured probability scores for yes/no, multiple choice, scale, or span questions — no retraining required. Use cases include detecting caller frustration, identifying AI-generated voices, and searching 40,000 recordings in minutes. The model achieved 70.7% agreement with human panel judgments, outperforming existing methods on accuracy, speed, and cost.

Runway has launched Dev plugins for Claude Code, Codex, and Cursor, connecting coding agents to its generative media API platform via the Runway Dev MCP. A single install gives agents access to account details, credit balances, model pricing, and Runway's skills for building with official SDKs. Agents can create Model Routers, build on ready-made Recipes, or call published Workflows as API endpoints. No API key is stored in the plugin. Targets indie developers, technical founders, and product engineers.

Starting in December, OpenAI will merge usage limits for ChatGPT and Codex into a shared token allowance across Plus, Pro, and Business plans. This change comes as OpenAI integrates Codex's agentic capabilities into the main ChatGPT experience. Usage is measured in tokens, with more advanced models and complex tasks consuming more of the allowance. Instant chat will not draw from the shared pool. Users can monitor combined usage in Settings → Usage, and may wait for resets, upgrade, or buy credits if limits are reached.

Andrej Karpathy built HackerTube, a YouTube alternative recommendation tool, in roughly 2 hours using Claude Opus 5.5. Frustrated with YouTube's algorithm, he had Claude filter 43 million Hacker News comments spanning 20 years down to 6,454 highly recommended videos. The tool requires no login, stores state locally in the browser, and uses mid-video frames as thumbnails instead of A/B-optimized uploads. Karpathy used Claude Code on Mac, manually only handling a Google Cloud API key, VPS setup, and domain purchase.

xAI has added invisible watermarks to text outputs from supported Grok models to comply with the EU AI Act. Starting November 7, 2026, the feature is enabled by default across all API endpoints for models including grok-4.7, grok-4.6, and grok-4.5. The watermark works by subtly shaping token selection during generation, adding no visible characters. Developers can check watermark status via the x-watermark response header. Team admins can opt out per model in the xAI Console, with all changes logged in the audit log.
