日报：ChatGPT 内建 MCP 部署与 Sol 成本基准
汇总 ChatGPT Sites 托管 MCP 服务器、GPT-6.1 Sol 单任务成本降至 0.72 美元、OpenRouter 选型框架及 GitHub 热榜。
AI and open-source updates today: OpenAI expanded the MCP ecosystem by letting users build and deploy MCP servers directly inside ChatGPT; Artificial Analysis benchmarked GPT-6.1 Sol task costs at $0.72 (a 30% drop); OpenRouter published a 3-step cost-versus-quality selection framework for Agent models. On GitHub, spec-kit led daily trending with +168 stars alongside qbittorrent/search-plugins with +150 stars. 1. ChatGPT Enables Direct Building and Deployment of MCP Servers ChatGPT Sites now hosts Model Context Protocol (MCP) servers. Developers can build and deploy MCP servers directly within the ChatGPT interface, turn them into plugins, and install them across web, mobile, and desktop clients, complete with granular private or public access controls. 🔗 https://x.com/thsottiaux/status/2105519215092584786 2. Artificial Analysis: GPT-6.1 Sol Task Cost Drops to $0.72 Independent benchmark tracker Artificial Analysis released new run metrics. GPT-6.1 Sol achieved an average Cost per Task of $0.72—30% lower than GPT-6 Sol ($1.05) and roughly 63% below GPT-5.6 Sol ($1.99), reducing operational expenses for long-horizon agent execution. 🔗 https://x.com/ArtificialAnlys/status/2105449959554441580 3. OpenRouter Releases Cost-vs-Quality Selection Framework for Agent Models OpenRouter introduced a three-step evaluation workflow to replace raw leaderboard picking: set a task-specific quality threshold, test cheap, mid-tier, and frontier models against 20-50 real examples to calculate cost per quality point, and deploy the lowest-cost model that clears the variance buffer. 🔗 https://openrouter.ai/blog/insights/cost-vs-quality-tradeoff-framework-for-agent-models/ GitHub Trending Today 4. github/spec-kit: +168 stars today GitHub's official toolkit for Specification-Driven Development (SDD). It standardizes specifications, prompt contracts, and AI-assisted engineering workflows from requirements through automated acceptance. 🔗 https://github.com/github/spec-kit 5. qbittorrent/search-plugins: +150 stars today The official search engine plugin collection for qBittorrent, providing maintained scraping and discovery scripts across major indexers. 🔗 https://github.com/qbittorrent/search-plugins
