大模型服務主戰場正轉向檢索增強問答、多文檔摘要和長程Agent。請求prompt由幾十到上百個語義獨立的片段（檢索文檔、技能說明、記憶、歷史輪次）拼接，形成數萬至數十萬token的超長上下文，預填充階段佔據主導算力開銷，成爲服務商最突出的成本來源，且引發更棘手的難題。
馬斯克旗下SpaceXAI發佈Grok 4.5，爲上市後首個重大更新。模型定位通用主力，可完成代碼編寫等任務。馬斯克稱其達到Opus級水平，但速度更快、Token效率更高且成本更低。
騰訊雲開發加碼微信AI小程序成長計劃：免費向開發者提供10億 Token 大模型額度，AI生圖額度從1萬張升至10萬張，大幅降低調用成本。核心模型同步升級。
AI編程的高API調用成本是開發者痛點，新工具pxpipe作爲本地代理，能將龐大上下文信息轉爲圖像，繞過昂貴的文本Token計費，顯著降低Claude Code使用開銷。其原理是在請求發送前精確識別並轉化冗長文本，實現“以圖省字”的降本增效。
