1. Mistral Large 4 权重开源：10 月 29 日权重已上线 Hugging Face，仓库是 mistralai/Mistral-Large-4-1T-A52B，约 1 万亿参数、52B 激活、100 万上下文，API 也降到 $0.70 / $2.10 每百万 token。许可证是 Mistral 修改版 MIT，自己跑可用 vLLM 或 SGLang，但做模型即服务需另签商业协议。来源：VentureBeat 报道 https://venturebeat.com/technology/mistral-large-4-le-chonk-arrives-as-the-top-open-model-outside-china-with-improved-coding-performance-and-63-lower-cost-per-task
2. DeepSeek 搜索 / 抓取免费今晚截止：通过 DeepSeek Harness、Claude Code、Codex 的服务端搜索和抓取调用，免费到北京时间 11 月 1 日零点，之后按 $0.75 / 千次计费，今天是最后一天，想用抓紧。deepseek-flash 本身淡季价 $0.15 / $0.60 每百万 token，权重是 MIT。来源：AIVIO 报道 https://aivio.news/news/deepseek-v4-1-flash-1017-search-fetch-api-pricing/
3. 免费 API 额度快照：OpenRouter 的 :free 模型是 20 次 / 分钟、50 次 / 天（曾经充过 $10 后可到 1000 次 / 天），Groq 是 30 次 / 分钟、每天 20 万 token，Cerebras 注册给 $5、每天 100 万 token，Gemini Flash 免费但内容可能用于改进产品。实操建议是 Gemini + Groq + OpenRouter 叠着用，别把关键任务押在单一免费层上。来源：免费 API 对比 https://continuumcode.ai/guides/free-llm-api/
4. MiniMax / Nemotron / Kimi 观察清单：MiniMax M3.1 Flash 权重已可下载，约 428B 参数、23B 激活、100 万上下文，但仅限非商业免费；NVIDIA 的 Nemotron 3.5 Bolt E4B 只有 8B，约 4GB 显存就能跑，适合端侧小模型。Kimi K3.1 Pro 目前只有 API，权重承诺 11 月 4 日前放出，先别等下载，11 月 4 日左右再去 Hugging Face 查。来源：十月模型盘点 https://www.swarchitect.net/en/ai-launches-2026-10-part2/
5. 学生免费算力组合：Kaggle 每周约 30 小时 T4 / P100、Colab 免费层会话最长 12 小时，两者叠加每周约 60 小时；Hugging Face ZeroGPU 免费账号每天 5 分钟、Lightning AI 每月 15 积分约 22 小时 T4。够做课程项目和原型，别指望预训练，额度会变、用前先看自己账号里的配额。来源：学生免费 GPU 指南 https://www.aquanode.io/blog/free-gpu-credits-for-students-and-researchers
6. GitHub Copilot 学生版：经 GitHub Education 验证的学生可免费领 Copilot Student，无限补全 + 每月 200 AI 积分，只能自动选模型，不能手动挑。6 月 17 日已重新开放申请，去 GitHub Education 福利页提交在读证明，每月会复核一次，失效就停。来源：申请指南 https://felloai.com/how-to-get-microsoft-and-github-copilot-pro-free/
