Ngesikhathi sendawo ngo-1 Septhemba, i-Anthropic yamemezela ukwethulwa kwamamodeli i-Claude Fable 5.1 ne-Claude Mythos 5.1. Le nkampani ithe la mamodeli amabili "angamamodeli omhlaba athuthuke kakhulu ohlelweni nomsebenzi wolwazi".
I-Fable 5.1 ne-Mythos 5.1 zisebenzisa imodeli eyisisekelo efanayo, kodwa ziyehluka ezingeni lokuvikela ukuphepha — i-Fable 5.1 ivulekele bonke abasebenzisi, kanti i-Mythos 5.1 inikezwa kuphela ngezinhlelo zokufinyelela ezethembekile ezikhungweni ezihloliwe emikhakheni yokuphepha ku-inthanethi nesayensi yezempilo.
Mayelana nokusebenza, imininingwane yezivivinyo zokulinganisa ekhishwe yi-Anthropic ikhombisa ukuthi i-Fable 5.1 idlule i-Fable 5 yangaphambilini, i-Opus 5 kanye ne-GPT-5.6 Sol yakwa-OpenAI ezivivinyweni eziningi.
Esivivinyweni socwaningo lwesayensi sama-agent i-Terminal-Bench-Science 0.1, i-Fable 5.1 ithole u-52.6%, kanti i-Fable 5 ithole u-24.7%, i-Opus 5 u-29.0%, bese i-GPT-5.6 Sol ithola u-22.4%.
Esivivinyweni sokuhlela sama-agent i-Terminal-Bench 4.0, i-Fable 5.1 ithole u-55.8%, kanti i-Mythos 5.1 ifinyelele ku-60.9% ngaphansi kokuvikelwa kokuphepha okuthambile.
Emsebenzini wolwazi, i-Fable 5.1 ithole amaphuzu angu-1853 esivivinyweni i-GDPval-AA v2, aphakeme kunamaphuzu angu-1824 e-Opus 5 kanye nangu-1723 e-Fable 5.
Ngokwentengo, izindleko zokufunda i-cache ze-Fable 5.1 zehliswe ngo-75%, zafinyelela ku-0.25 USD ngamathokheni ayisigidi. Ngomthwalo ojwayelekile womsebenzi, izindleko ze-Fable 5.1 ziphansi cishe ngo-25% kune-Fable 5; emithwalweni yomsebenzi esebenzisa ama-agent kakhulu, izindleko zingehla ngofinyelela ku-45%. Intengo eyisisekelo ayikashintshi: ama-tokens okokufaka angu-10 USD ngesigidi, kanti awakhiphayo angu-50 USD ngesigidi.
Mayelana nokugcinwa kwedatha, i-Anthropic yethule izinyathelo ezintsha zokuvikela ezisezingeni eliphezulu zamabhizinisi (Enterprise Frontier Safeguards, EFS). Lesi sixazululo sihlanganisa ukuvikelwa kobumfihlo bokungagcini nhlobo idatha kanye nokuvikela ukuphepha okuthuthukile. Idatha yamakhasimende igcinwa kwingqalasizinda yamafu elawulwa ngokuphelele yibhizinisi, hhayi ezinhlelweni ze-Anthropic. I-EFS izoqala ukwethulwa kancane kancane kumakhasimende ezinkampani ekwindla yalo nyaka. Ngaphambi kokuba i-EFS itholakale, amakhasimende afanelekayo angasebenzisa i-Fable 5.1 ngaphansi kwenqubomgomo yokungagcini nhlobo idatha.
Mayelana nokuvikelwa kokuphepha, i-Anthropic ithuthukise indlela yokuvikela ye-Fable 5.1 ukuze kuncishiswe izexwayiso ezingamanga.
Emkhakheni wokuphepha ku-inthanethi, inani lokuvinjwa okubangelwa izexwayiso ezingamanga ngaphansi kwezinyathelo ezintsha zokuvikela lehle cishe ngo-60% uma liqhathaniswa nangaphambili. I-Fable 5.1 manje ingasetshenziselwa ukuthola ubuthakathaka besoftware, kodwa ngeke isetshenziselwe ukwakha izinhlelo zokuxhaphaza lobo buthakathaka.
Emkhakheni webhayoloji, i-Anthropic ibambisene nohulumeni wase-United States ukwakha uhlelo lokufinyelela oluvumela abacwaningi ukuba basebenzise amakhono athuthukile ebhayoloji e-Mythos 5.1, futhi ihlela ukuvula ukubhalisela ososayensi maduze.
Mayelana namakhono esayensi, i-Anthropic ikhombise imiphumela ye-Mythos 5.1 emikhakheni eminingi. Emkhakheni wokuklama ama-molecule, i-Mythos 5.1 isebenzise amathuluzi omthombo ovulekile okuklama nokugoqa amaprotheni ukuze iklame izibophezeli ezinokuhlangana okuphezulu. Ezindaweni ezintathu eziqondiswe kuzo, amandla ayo okuhlangana abe phezulu ngokuphindwe ka-10 kunomsebenzi ohamba phambili emncintiswaneni wokuklama amaprotheni we-Adaptyv Bio; ezindaweni eziqondiswe kuzo ezingu-12, izinga lokuthola okuhlosiwe beliseduze no-50%, kanti izinga elijwayelekile lamanje lokuthola okuhlosiwe ekuklameni amaprotheni liyi-10% kuya ku-15%.
Emkhakheni wokuhlaziya ngekhompyutha, i-Fable 5.1 iqeqeshe inethiwekhi ye-neural isebenzisa izithombe ze-radar ezivela emsebenzini we-NASA i-Magellan eminyakeni engaphezu kwengu-30 edlule, yakha imephu yokuphakama enokulungiswa okuphezulu ehlanganisa ingxenye eyodwa kwezintathu yeVenus. Ukulungiswa kwayo kuthuthukile kusuka kumakhilomitha angu-10 kuya kwangu-20 ngaphambilini kwaba amakhilomitha angu-2 kuya kwangu-3, kanti ukunemba kokuphakama kukhuphuke ngo-25%.
Emkhakheni webhayoloji yekhompyutha, i-Mythos 5.1 inyuse isivinini samamodeli ayisikhombisa okufunda okujulile anomthombo ovulekile safinyelela kokuphindwe ka-2.5 ngokubhala ama-kernel e-GPU enziwe ngokwezifiso kanye nokugcina imiphumela ephakathi, okulindeleke ukuthi kwehlise izindleko ze-GPU ngo-30% kuya ku-60%.
Mayelana nokuhambisana nemithetho, i-Anthropic yasayina ngoJulayi 2026 iziqondiso zokusebenza ze-European Union eziphathelene nokusobala kokuqukethwe okukhiqizwe yi-AI ngaphansi koMthetho we-AI. Ngokwalezi zidingo zomthetho, imiphumela yamamodeli ekhishwe ngemva kuka-2 Agasti 2026 kufanele ifake i-watermark engabonakali.
I-Fable 5.1 isivele ifake le watermark engabonakali emibhalweni ekhiqiziwe (Qaphela: le watermark ayibonakali kubasebenzisi abangenayo i-API yokuyithola; ayithinti ikhwalithi noma okuqukethwe kwemiphumela, futhi ayiqukethe noma yiluphi ulwazi lomsebenzisi noma lwezingxoxo zakhe).
I-Anthropic yethula i-API yokuthola le watermark ngendlela yokubuka kwangasese. Izikhungo ezifanelekayo, njengeziphathimandla ezilawulayo, abomthetho, abezindaba nezikhungo zokuhlola amaqiniso, zingayisebenzisa ngokwezidingo zomthetho we-European Union.
I-Claude Fable 5.1 isiyatholakala kuzo zonke izinkundla, okuhlanganisa i-Amazon Web Services, i-Google Cloud ne-Microsoft Azure, futhi onjiniyela bangayisebenzisa nge-Claude API; i-Claude Mythos 5.1 okwamanje inikezwa kuphela izinhlangano zase-United States ezihloliwe.
