AI model naam ka matlab — "GPT-6 Sol", "Claude Fable 5.1", "Gemini 3.8 Flash" — teeno cheezein alag system se aati hain, aur 2026 mein teeno companies ne apna pattern badal diya hai. Ek line mein rule: number generation batata hai, naam (Sol, Fable, Flash) tier batata hai — kaunsa model kitna strong ya kitna fast. Ye post teeno naming systems ko decode karti hai, sab official sources se (June-September 2026 updates), taaki agla launch aap dictionary mein dhundhne ke bajye 5 second mein padh lo.
Naam ko teen hisson mein toda karo
Har modern model naam do cheezein bundle karta hai jo asal mein alag hain: generation (kaunsi training run, kitni nayi) aur tier (speed vs depth ka lane). Jab tak ye same label mein the, "GPT-5.5" jaise naam ka matlab tha "bas newer". Ab dono alag ho gaye — aur har company ne apna tarika chuna hai.
OpenAI: number = generation, Latin naam = tier
Purana pattern sab jaante hain: GPT-1 → 2 → 3 → 4 → 5, "o" (4o = omni, multimodal), ".5" = mid-cycle. 26 June 2026 ko GPT-5.6 ke saath OpenAI ne pattern toda: Sol, Terra, Luna — ek generation, teen durable tiers:
| Naam | Matlab (etymology) | Tier | GPT-5.6 pricing (per 1M, in/out) |
|---|---|---|---|
| Sol | Latin "Sun" | Flagship — deep reasoning | $5 / $30 |
| Terra | Latin "Earth" | Balanced workhorse | $2.50 / $15 |
| Luna | Latin "Moon" | Fast, low-cost | $1 / $6 |
Aur ab GPT-6 (September 2026) isi system ko aage le jaata hai: GPT-6 Sol flagship ($2/$10, ~872K context — apidog Sep 23, 2026), GPT-6 Luna budget lane ($0.10/$0.50), aur GPT-6 Astra (Latin "stars") — OpenAI ka khud ka headline hai "A new generation of intelligence", max/xhigh compute tiers wala. (Launch ke waqt preview sirf ~20 government-approved partners tak seemit tha — toh naam sunna ≠ use kar paana.) Matlab: celestial Latin family ban chuki hai — Sun flagship, Moon fast, Earth balanced, Stars nayi intelligence class. Design Arena models page (22 Sep 2026) par teeno live hain.
Kya padhna: GPT-6 Sol = generation 6, flagship lane. gpt-5.6 Terra = wahi 5.6 generation, balanced lane — "5.6 > 6?" nahi, number hamesha generation dikhata hai, naam lane.
Anthropic: class + tier + version — teen layer
Anthropic ka system teeno mein zyada layered hai (official announcement + Nightschool explainer, July 2026):
- Class = generation leap: abhi Mythos class chal raha hai. Iska pehla public model Claude Fable 5 — 9 June 2026 ko release hua (anthropic.com/news/claude-fable-5-mythos-5). Naya class naam matlab "version bump nahi, generation jump hai".
- Tier = poetry spectrum: Haiku (fast, chhota — 17-syllable poem), Sonnet (balanced — 14-line poem), Opus (flagship — sabse zyada capability). Current versions: Opus 5.5 (Sep 2026), Sonnet 4.6, Haiku 4.5.
- Number = version counter, generation NAHI:
Sonnet 4.6ka matlab Sonnet tier ka 4.6 update — ye "family 4.6" nahi hai.
Fable/Mythos ki literary theme yaad rakho — mythos (kahaani) → fable (kahani) — sab words storytelling se aate hain, poetry (Haiku/Sonnet) se nahi. Isliye "Fable 5.1 kya hai" ka seedha jawab hai: Mythos class ka model, tier number ke system ka hissa nahi — aur haan, <!-- TODO internal link: Claude Fable 5.2 leak --> wali tarah .1 updates point-releases hain, nayi family nahi.
Google: Flash, Pro, Lite — naam hi speed hai
Gemini sabse straightforward rakhta hai (ai.google.dev docs, updated 22 Sep 2026):
- Flash = fast + sasta tier. Ab Gemini 3.8 Flash current hai — Google ka khud ka description: "our most intelligent Flash model", long-horizon coding aur agents ke liye. Peeche 3.7, 3.6, 3.5 Flash (legacy).
- Flash-Lite = aur bhi sasta/faster variant (3.5 Flash-Lite, 3.1 Flash-Lite).
- Pro = balanced flagship — Gemini 3.1 Pro abhi plans mein hai (paid tiers mein).
- Ultra/Nano — Ultra kabhi sabse bada (Gemini Advanced), Nano on-device.
- Alag family words: Nano Banana = image generation, Veo = video, Lyria = music — ye Gemini LLM ke "versions" nahi hain, alag products hain.
Google ka ek bonus system jo log miss karte hain — model string suffixes: stable (pinned, production ke liye), preview (billing on, deprecation notice ke saath), latest (alias — har release par hot-swap!), experimental (feedback ke liye, production nahi). Matlab gemini-flash-latest kal alag model point kar sakta hai — production code mein hamesha exact stable id (jaise gemini-3.6-flash) use karo, warna bill ya behavior bina bataye badal jaayega.
Quick reference: agla naam kaise padhoge
| Name padha | Poochho | Jawab kahan milega |
|---|---|---|
| Number hai? (5.6, 3.8, 4.6) | Generation ya tier version? | OpenAI/Google = generation; Anthropic = tier ka counter |
| Latin/word naam? (Sol, Luna, Fable, Flash) | Tier signal hai — flagship ya fast? | Docs ka pricing: mehnga = flagship, sasta = fast |
| Suffix? (preview, max, lite, latest) | Stability/ compute lane | stable/exact id = safe; latest = moving target |
.1/.5 point update? | Naya version, nahi family | Release notes dekho, benchmark nahi naam |
Do traps jo cost bachate hain: (1) naam ki strength ka benchmark se koi guarantee nahi — "Sol" ka matlab premium pricing hai, best-in-class nahi (real scores toh <!-- TODO internal link: Design Arena leaderboard --> jaise crowdsourced charts par dekhein); (2) free/access wale pages par purane naam milenge — GPT-4o-era articles 2026 ke tier system ko miss karte hain, isliye hamesha docs date check karo.
Ek caution se close: alias (-latest, kisi bhi company ka) use karo tab jab tumhe flexibility chahiye; exact version tab jab bill, safety behavior ya output format pin karna ho. Naming ab marketing nahi, config hai — aur galat padha hua naam seedha production incident ban sakta hai.
FAQs
GPT-6 ke Sol, Luna aur Astra ka kya matlab hai?
Ye OpenAI ke capability tiers hain — generation number se alag. GPT-5.6 (June 26, 2026) ke saath system shuru hua: Sol = Latin "Sun", flagship reasoning; Terra = "Earth", balanced; Luna = "Moon", fast/cheap ($1/$6 per 1M). GPT-6 (Sep 2026) mein Sol flagship ($2/$10), Luna budget ($0.10/$0.50) hai, aur Astra (Latin "stars") nayi intelligence class hai — OpenAI ka headline "a new generation of intelligence".
Claude Fable 5 kya hai — ye konsa "version" hai?
Fable 5 Anthropic ke Mythos class ka pehla public model hai (9 June 2026). Anthropic ab do-layer naming use karta hai: class naam (Mythos = generation jump) + tier naam (Haiku fast, Sonnet balanced, Opus flagship) + version counter (Sonnet 4.6 jaisa). Fable tier number system ka hissa nahi — isliye "Fable 5.1 vs Opus 4.8" direct version comparison nahi hai, class vs tier comparison hai.
Gemini mein Flash aur Pro ka farak kya hai?
Flash = fast aur cost-effective tier (abhi Gemini 3.8 Flash — agents/long tasks ke liye optimized, legacy 3.5/3.6/3.7), Flash-Lite = aur sasta, Pro = balanced flagship (Gemini 3.1 Pro). Model string par stable, preview, latest, experimental suffixes stability batate hain — latest alias har release par badal sakta hai, production ke liye exact stable id use karein.
Kya naam se model ki quality guaranteed hai?
Nahi. Naam sirf generation aur lane (fast vs flagship) batata hai — pricing spectrum hai, leaderboard nahi. Same generation ke tiers alag jobs ke liye hote hain: Sol/Opus/Pro mehngi depth ke liye, Luna/Haiku/Flash speed ke liye. Quality dekhni ho toh current benchmark aur release date dekho — jaise Sep 2026 ke crowdsourced design leaderboards, jahan har naam ke peeche rating likhi hoti hai.
