14 days ago
- InstantVideos allows users to generate documentary videos quickly by typing any topic, with a promise of a finished video in under a minute.
- Upon payment, credits are added to the user's account, indicating a credit-based system for video generation.
- Users can choose between short formats like TikTok videos, long-form content, or a 'Surprise me' option for automated selection.
- The 'Generate Video' button initiates the video creation process, with a 'Loading credits...' message and a 0.0s timer suggesting real-time or rapid processing.
Show HN: Adaptive Recall, persistent memory for AI assistants over MCP
8 days ago
- Adaptive Memory for AI Applications: a memory system that learns from every interaction, improving retrieval quality over time, powered by cognitive science and machine learning.
- Goes beyond standard vector search with six unique capabilities, including adaptive retrieval, cognitive scoring, knowledge graph integration, memory lifecycle management, self-improving system, and a simple API.
- Features adaptive retrieval with four parallel search strategies, cognitive ranking using ACT-R modeling, automatic knowledge graph creation, dynamic memory progression, ML-based self-improvement, and an easy-to-use API with eight tools.
- Built and maintained by AI Apps API, designed to work with Claude Code and other CLI tools via MCP or plain HTTP REST for any application.
xAI's Grok Build CLI Uploads Git Repositories to a Google Cloud Bucket
7 days ago
- xAI disabled the Grok Build CLI's ability to upload entire developer repositories to cloud storage after a security researcher exposed the behavior.
- The CLI was bundling and uploading full repositories, including Git history and secrets, to a Google Cloud Storage bucket, unrelated to the specific coding task.
- A toggle labeled 'Improve the model' did not stop the uploads; it only governed training consent, not data collection.
- The fix was implemented silently via a server-side flag, with no official advisory or statement from xAI on the purpose or fate of already collected code.
- The researcher's findings highlight undisclosed collection but do not confirm misuse, such as whether xAI trained on or viewed the uploaded code.
AXI – Agent EXperience Interface
2 days ago
- AXI (Agent eXperience Interface) is a set of 10 design principles for creating agent-ergonomic CLIs that aim for 100% task success at the lowest cost.
- Benchmarks show AXI outperforms both raw CLI and MCP (Model Context Protocol) approaches in browser automation and GitHub tasks, achieving higher success rates with lower average costs and durations.
- Key AXI principles include using TOON (Token-Optimized Object Notation) for 40% token savings, returning aggregate fields to eliminate round trips, truncating large text, and providing contextual next-step suggestions.
- AXI's specialized commands like 'tables --url' combine multiple operations, reducing turns, while shell composability (e.g., '| grep') keeps token volumes compact.
- The interface ensures mutations are idempotent, errors are structured, and commands avoid interactive prompts, with a 'home view' showing live data instead of help text.
- Community and official AXI implementations exist for various domains, including GitHub, browser automation, Slack, AWS, Docker, and databases.
