人工智能太昂贵乎?吾于膝上之机,免费运行之。
Lingdas1 · 2026-05-24 · via DEV Community

Lingdas1

人工智能之费过巨乎?吾以笔记本电脑免费运行之(此乃其法也)

医学生之指南,以无分文之订阅费使用人工智能


吾忆彼时,弃人工智能之精确时刻

时在二零二六年正月。吾目视ChatGPT Pro每月二百美元之价签,复视吾之银行账户。吾为中国医学生——吾每月之“额外”预算,仅足购两杯珍珠奶茶而已。

"人工智能,乃富贵者之玩物也。"吾思之。或其公司所费者。

吾閉之,復學。

然我终不能释怀,似有所失。众皆言人工智能——编程之助,研习之器,作文之援。而我独困于谷歌,惟祈愿而已。

三月之后,吾以五年之旧机,运行GPT-4级之模。无偿。无订阅,无API账单,无云服务积分。

吾之行事如是,尔虽非程序师,亦可如是为之。


所欺之妄言

此乃人工智能之要义,鲜有人道也。尔无需云。

凡AI之公司,皆欲使尔信尔需其月费贰拾元之计。或其月费贰佰元之Pro计。或其企业计(询价!)。

何哉?盖其每使尔键一语,即得利也。

然其术乎?其真AI之模乎?乃开源也。无价。公诸。任人可下载而运行。

吾之所以未为之者,盖因无人告吾可也.


所思与所学

昔者:

"欲于本地运行AI?需五千美元之游戏PC,兼液冷之属。"

今者:

吾之笔记本电脑,内存八千兆,GPU乃二零二一年中档之器。运行AI模型,答问、撮要、助学——皆于本地,皆无偿。

前:

汝须为编程者,方得设此。

其后

吾乃医学生也。吾知解剖,不知API。吾能之,则人皆能之。

前:

地之AI,不若ChatGPT。

其后

凡日常之事——为文、研习、谋篇——其别不察。且于某些事(如隐私、无审查、用之无度),本地之智实


今示君以吾日常所为,皆于 laptop 上,且皆免费:

1. 学问之助

吾抄录课本章节,而问之。此模解难义,以简明言。不复观费资之YouTube教程.

2. 文书助手

文辞、书简、笔记——吾速草之。此模献善策,然不更易全篇(吾尚习英语,故需此练).

3. 研究之伴

吾以PDF之形下载研习之文,复询其义。"撮其要旨,列三点。" "此研之主弊何在?"

4. 脑力之伴

每困于思,吾与AI论之。若友,未尝厌吾之问。

5. 语言之习

吾有所作,命AI正其文,察其谬而习之。若七日二十四时皆在侧之师,无费而得教也。


所需何物(直言)

诚言尔所需。勿饰以商贾之辞,但陈其实。

最简之设

  • 凡机可任(Windows、Mac、Linux——纵二百金之旧机亦可)
  • 至少需八吉内存(十六吉为佳,然八吉亦可)
  • 网络之连以供初载(需时十至十五刻)

止此而已。无需殊异之GPU。无昂贵之硬器.

"噫,吾闻需博弈之显卡耶?"

欲得速效,需以游戏GPU——然不可得。所需一。运行于CPU之模型,其速较缓(思5-10秒应答,非1-2秒),然于多数之事,皆可无碍。

其形如何

通篇大要,不过如是。

1. Download a free program (Ollama) — 2 minutes
2. Pick a model (the "brain") — 1 click
3. Start chatting — immediately

入全景模式 出全屏模式

此乃全程。吾将继以图文,分步详述之。今且知其然耳。甚为简明胜于所思。


无人言之隐私之赏

此乃吾所未期。隱私。

尔用ChatGPT或Claude,所书皆往其服务器。尔之问,尔之文,尔之私思。

尔于本地运行AI:

  • 🔒 诸事皆留于尔之机。
  • 🔒 无人得见尔之语。
  • 🔒 无数据之集。
  • 🔒 无网亦能作。

医学生于轮转期间掌管患者机密资料,此诚大事。然即平素之用——日记、私业、冥思——知己之数据为己有,亦佳。


然则,果真善乎?

此吾所遇之问也。容以诚答之:

于多数平日常务?诚善矣。

  • 書信撰寫 → ✅ 良善
  • 撮要诸文 → 甚善
  • 谋篇构画 → 甚善
  • 释概念→✅善
  • 著文如织 → ✅ 善(得宜之模)
  • 繁复之数理 → ✅ 良善(以DeepSeek-R1)
  • 文思创作 → 🟡 中等(因型号而异)
  • 实时对话 → 🟡 CPU稍慢

尔所实失者: 至上之模(GPT-4o, Claude Opus)犹在云端。然吾所需AI者十之九,本地之模已足善矣。


吾为何而书此

吾非科技之影响者。吾不售课程,亦无联属之链。吾惟医学生耳,初见AI之价甚昂,后知不必尔尔。

吾所遇诸指南,皆由程师所撰,为程师而撰也。彼等以为吾知所谓"终端"者,知"GGUF"之义,晓"克隆仓库"之法。

吾实不知其一二。至今犹懵懂。

然吾得窥一二,已足使之事成。吾能之,汝亦能之。


来者何事

吾将撰浅近之指南,以授为AI所遗之人:

  • 第二部: "何谓大语言模型?(非魔法也)" — 以浅言释人工智能
  • 第三部: "分步详述:十分钟运行首个人工智能模型" — 附图示
  • 第四部: "本地人工智能五项免费应用" — 实用案例
  • 卷五: "地AI與ChatGPT:誠實對比"—無偏見,唯事實

標記此倉庫或在此跟隨我,以獲知其更新通知.


結論

AI非奢侈品。技藝無價,器用簡易,汝與自由AI之間唯一阻隔者,乃知其存在耳。

吾尝数月以为AI非吾所能及。岂知向之所能,惟不知其所在耳。

今汝之笔记本电脑,即可运行AI,且无偿,且有效。

医学生虽无编程之基,犹能解之,汝亦能之。


吾乃凌也。居华夏,习医道,偶入人工智能之境。无计算机科学之学位,亦无巨企之职,惟携一笔记本电脑,怀万千好奇,信人工智能当惠及众生。此乃吾“人工智能惠及凡人”系列之首篇.

若觉此篇有益,可赞之⭐.请赞GitHub仓库,以获新指南之通知。或留言——吾必一一览之。
