Isifinyezo se-GPT, kwiminyaka embalwa nje, sibe luphawu lokuphazamiseka okukhulu kwezobuchwepheshe. Emva kwezi leta zintathu kukho utshintsho olucacileyo: sisuke kwizixhobo zekhompyutha ezilawulwa yimiyalelo saya kubantu esisebenzisana nabo kwidijithali esithetha nabo. Ukuze siqonde ngokwenene ubukhulu bale nguqu, umntu kufuneka ajonge phantsi kwekhava aze ahlole indlela ezintsonkothileyo ngayo ezi ngqondo.
I. Inkcazo yoBugcisa: Iintsika ezintathu zesifinyezo
I-GPT imele i-Generative Pre-trained Transformer. Igama ngalinye lichaza inqanaba elibalulekileyo ekudalweni kwemodeli.
1. Imveliso evelisa izinto ezintsha
Kwihlabathi lobukrelekrele bokwenziwa, ngokwesiko kukho umahluko phakathi kweentlobo ezimbini zeemodeli: ezicalulayo nezivelisayo.
- Imodeli yocalucalulo ujonga idatha aze ayinike ilebheli (umz., “Le yifoto yekati”).
- Imodeli yokuvelisa, njenge-GPT, iyaqhubeka. Ngokusekelwe kulwazi lwayo, inako ukuvelisa idatha entsha ngokupheleleyo eyayingekho ngaphambili. Ukuba ihlalutye izigidi zeembongo, ayiyi kuyiphinda ngentloko; iya kubhala entsha, ihlonipha imithetho yerhyme kunye nemitha "eyiqondileyo."
2. Uqeqeshwe kwangaphambili
Kulapho amandla akhoyo. Ngaphambi kokuba ifike kwiscreen sakho, imodeli idlule kwinqanaba lokufunda elikhulu. Khawuthelekelele ithala leencwadi eliqulethe inxalenye enkulu ye-intanethi yehlabathi: yonke iWikipedia, iilayibrari zedijithali, iiforam zengxoxo (ezifana neReddit), iindawo zokugcina iikhowudi zekhompyutha (iGitHub), kunye neengxelo zeendaba.
Kangangeenyanga, kumawakawaka eeprosesa ezinamandla aphezulu, imodeli "yayifunda" le tekisi ukuze ifunde kungekuphela nje iinyani ezithile, kodwa nolwakhiwo olunzulu lolwimi ngokwalo. Olu "qeqesho lwangaphambi koqeqesho" luvumela imodeli ukuba ifike inemvelaphi yenkcubeko kunye nolwimi oluqhelekileyo ngaphambi kokuba ifumane umbuzo wayo wokuqala.
3. Isitshintshi
Le yayiyinkqubela phambili yesayensi ka-2017, evela kwiphepha lophando likaGoogle elinesihloko esithi “Ingqalelo kuko konke okufunayo.” Ngaphambi kweTransformer, iimodeli ze-AI zazifunda izivakalisi igama negama, ngokulandelelana kwazo (iimodeli eziphindaphindayo). Nangona kunjalo, iTransformer ijonga isivakalisi siphela ngaxeshanye.
Ngenxa yendlela ebizwa ngokuba yi-Attention, inokulinganisa ukubaluleka kwegama ngalinye xa lithelekiswa namanye. Kwisivakalisi esithi “Isilwanyana asizange siwele isitalato kuba sasidiniwe kakhulu,” iTransformer iyaqonda ukuba “it"ubhekisa kwisilwanyana." Ukuba isivakalisi siphela ngo "kuba yayibanzi kakhulu"," iyaqonda ngoko nangoko ukuba "i" ibhekisa esitalatweni. Olu buchule bokuqonda imeko enzima yilo nto eyenza iimpendulo ze-GPT zivakale ngathi zezobuntu.
II. Imbali emfutshane yokuzivelela kwezinto: Ukusuka kwi-GPT-1 ukuya kwi-GPT-5
Ibali le-GPT libonisa ukukhula okubonakalayo, okuqhutywa yinkampani. I-OpenAI.
Ukuvuka (i-GPT-1 kunye ne-GPT-2)
Ngowama-2018, i-GPT-1 yabeka isiseko. Yayinokwenza imisebenzi elula, kodwa inkumbulo yayo yayimfutshane. Ngowama-2019, i-GPT-2 yanda kakhulu ngeeparamitha ezili-1.5 leebhiliyoni (unxibelelwano lwangaphakathi lwemodeli). Yaba nobuchule kakhulu ekuveliseni umbhalo ohambelanayo kangangokuba i-OpenAI ekuqaleni yayithandabuza ukuwukhupha, isoyika ukuba iza kusetyenziselwa ukudala ulwazi olungelulo olusemgangathweni wemizi-mveliso.
Ukuqhuma (GPT-3 kunye ne-3.5)
Ngowama-2020, i-GPT-3 yanqumla umqobo wengqondo ngeeparameter ezili-175 leebhiliyoni. Yayisisilo esisebenza ngokubala. Yayingasenguye umguquleli okanye umbhali nje kuphela; yaba nakho ukuqiqa ngengqiqo kunye nokubhala kwiilwimi ezininzi zeenkqubo. Inguqulelo ye-GPT-3.5 yasebenza njengenjini yokwazisa uluntu nge-ChatGPT ngoNovemba ka-2022, nto leyo eyabangela uvakalelo kwihlabathi liphela.
Ukuvuthwa (i-GPT-4 nangaphezulu)
Ikhutshwe ngo-2023, i-GPT-4 inee-multimodal. Ingahlalutya imifanekiso, isombulule iingxaki zezibalo ezintsonkothileyo, kwaye ibonise amanqanaba aphezulu kakhulu obuchule bokuyila. Ukuchaneka kwayo kuphuculwe ukunciphisa "iimbono ezingezizo" (amaxesha apho i-AI ivelisa iinyaniso ngokuzithemba).
Ezihlobene: I-ChatGPT-5 engenamda neyasimahla kwi-AI yasimahla kwi-Intanethi
III. Imisebenzi Yangaphakathi: Umatshini Onokwenzeka
Ngokuchasene nenkolelo ethandwayo, i-GPT ayinayo "iingcinga" okanye izimvo. Ukusebenza kwayo kuxhomekeke kwizibalo kuphela, kodwa kubanzi kangangokuba ilinganisa ubukrelekrele.
Xa umsebenzisi echwetheza umbuzo, imodeli iguqula igama ngalinye libe lulandelelwano lwamanani abizwa ngokuba yi-embeddings (okanye i-vectorization). La manani avumela amagama ukuba abekwe kwindawo yezibalo enamawaka eemilinganiselo. Kule ndawo, igama elithi "uKumkani" ngokwezibalo lisondelelene nelithi "uKumkanikazi" okanye "uMqhele."
Inkqubo yokuphendula luhlu lwezibikezelo:
- Le modeli ihlalutya kha wuleza.
- Ibala ukuba leliphi igama (okanye “uphawu“) inethuba eliphezulu lokuqala impendulo.
- Xa elo gama likhethiwe, liyalibuyisela kuhlalutyo lwalo ukuze liqikelele igama elilandelayo.
- Iphinda le nkqubo ide ifikelele kwinqanaba lokuphela.
Okwenza isiphumo sibe nomtsalane kukuba i-GPT ayisoloko ikhetha igama elinokwenzeka kakhulu (eliza kuyenza iphindaphindeke kwaye ikruquke), kodwa isebenzisa useto "lobushushu" (ulawulo olungacwangciswanga) ukutshintsha isitayile sayo kunye nobuchule bayo.
IV. Inyathelo elibalulekileyo: Ulungelelwaniso lomntu (RLHF)
Ukuba unika umatshini yonke i-intanethi ukuba ayifunde, inokuba semngciphekweni wokuba ndlongondlongo okanye inike iingcebiso eziyingozi, njengoko i-intanethi iqulethe zombini ezilungileyo nezimbi zoluntu.
Ukuze i-GPT ibe “yeyomntu,” i-OpenAI isebenzisa i-Reinforcement Learning evela kwi-Human Feedback (RLHF). Amawaka abantu abavavanyayo basebenzisane neenguqulelo zokuqala zemodeli, benika umlinganiselo wempendulo: “Le yimpendulo elungileyo,” “Oku kukrwada,” “Oku kubuxoki.”
Ngale nkqubo, i-AI yafunda ukwamkela ukuma komncedisi oluncedo, ongathathi cala, nobophelelekileyo kwimigaqo yokuziphatha. Olu luhlu lokugqibela luguqula ubuchwepheshe obungacwangciswanga bube yimveliso ethengiswa kakhulu.
V. Imingeni kunye nemida
Nangona inamandla, i-GPT isesisixhobo esinamabala angabonakaliyo:
- Ukohlwaywa: Ngenxa yokuba ifuna ukuthembeka ngokwezibalo, isenokuyila ibali lobomi okanye umthombo osemthethweni ongekhoyo, kuba nje amagama athi “avakala” kunye.
- Ukungabikho zingqondweni: I-GPT ayiva nto. Ayinalo ulwazi ngehlabathi elibonakalayo. Ukuba ichaza indlela yokupheka i-omelet, ayazi ukuba yintoni ubushushu okanye ivumba leqanda; yazi kuphela ulwalamano lolwimi phakathi kwezo ngcamango.
- Iindleko zokusingqongileyo: Ukuqeqesha nokusebenzisa ezi modeli kufuna umbane omkhulu namanzi (ukuze kupholiswe iiseva).
isiphelo
I-GPT ingaphezulu kakhulu kunesoftware yokucubungula amagama. Sisiseko solwazi. Kanye njengokuba umbane uvumela ukusetyenziswa koomatshini bomsebenzi womzimba, i-GPT iqala ukwenza ezinye iintlobo zomsebenzi wobukrelekrele zibe zezona zizenzekelayo.
Ngokuqonda ukuba i-GPT imele i-Generative (indalo), i-Pre-trained (ulwazi olukhulu), kunye ne-Transformer (ukuqonda okusemgangathweni), sinokuqonda ngcono ukuba kutheni le teknoloji iphawula inguqu. Sisekuqaleni nje kokuhlola oko ezi modeli zilula ngakumbi nezikrelekrele ziya kuzisa kwisayensi, imfundo, kunye nokudalwa kobugcisa.
