What we're armed for

Every unreleased Gemini model on the board, swept every 60 seconds. Odds are live Polymarket prices where a market exists: sentiment, not a promise.

• Gemini 3.9 (next Flash revision)81% by Dec 31 · market: Next Gemini Flash (3.9 or later)
  Unannounced — armed on the cadence (3.6 Jul 21, 3.7 Aug 13, 3.8 Sep 2)
• Next Gemini Flash-Lite32% by Nov 30 · market: Next Gemini Flash-Lite (3.6 or later)
  No date · Flash-Lite is on 3.5 while Flash reached 3.8; Polymarket runs a 'next Flash-Lite (3.6+)' market · Oct 25: widened to a gemini-4-flash-lite id, which would otherwise file as a variant of live Gemini 4 · Nov 10: a Google engineer's public side project maps the flashLite tier to gemini-4-helix ids (unconfirmed); those ids go to the gemini-helix hunt
• Gemini 3.5 Pro (gemdelta)
  Internal id per an Aug 6 leak — not on the public arena board when checked
• Gemini 5
  Not announced — no Google word or date; Gemini 4 Argon shipped Oct 13
• Gemini experimental release
  Unnamed early build · Google shipped these as gemini-exp-MMDD before Gemini 2; Gemini 4 then shipped Oct 13 under its own name, Argon
• Gemini Krypton
  Rumored, not announced · Nov 9 12:36 UTC: @LuminaBench posts a screenshot he says shows 'Krypton' among Google's Gemini models in Design Arena's providers list; Design Arena's public leaderboard and models page (read 12:50 UTC) do not list it · Nov 9 15:01 UTC: @Mr_Salio says Gemini 4 Xenon and Radon are on Design Arena too; Design Arena's /api/registry (read 15:50 UTC) lists argon, krypton, xenon and radon only as anonymous private labels with no lab, and its one model with id radon is Meta's Muse Spark, so neither name is tied to Google there

  Nov 9 06:12-07:55 UTC: @chetaslua posts outputs he says come from 'Gemini Krypton' ('krypton-a version first checkpoint'), compares it with Gemini 4 Carbon and Argon, and says it takes about twice as long on the same prompt; he does not say where he runs it; @Mr_Salio relayed it · one account, unconfirmed, and Google has not named a Krypton · Google's Gemini 4 builds use element codenames: Argon shipped as gemini-4-argon (Oct 13), Carbon was announced Oct 28, Barium was reported by Business Insider (Oct 9) · whether Krypton would ship as a Gemini 4.x or a Gemini 5 is unknown; this hunt fires on any gemini id containing krypton · Nov 9 10:16 UTC: a second account, @lyraxana, posts side-by-side videos labelled 'Gemini 4 Krypton vs Carbon vs Argon', the first use of a Gemini 4 prefix for it; still unconfirmed, Google has said nothing · Nov 9 11:27-11:28 UTC: @LuminaBench and @kimmonismus amplified the outputs; kimmonismus says he cannot verify them · no krypton id on OpenRouter or models.dev (11:49 UTC)
• Gemini Omni Pro
  Leaked — expected to ship alongside Gemini 3.5 Pro, and that anchor is gone: our own 3.5 Pro row records it reported cancelled (9to5Google, Sep 30; no Google statement) and Google stepping back from 3.5 Pro to focus on Flash (Sep 24), with Gemini 4 taking the top slot as Argon on Oct 13 · Nov 8: the Omni line has shipped twice since the leak with no Pro tier (Omni 1.1 Flash GA Aug 27, Omni 1.2 Flash Nov 5), and our sweep's cumulative ledger of 627 catalog ids has never carried an Omni Pro id — its only Omni ids are gemini-omni-1.1-flash and gemini-omni-1.2-flash · hunt left armed, since a Pro tier can still arrive on its own
• Next Gemini 4 (4.1+, Barium)
  No date · Oct 22: @lyraxana says the Carbon checkpoint on LMArena and in the Gemini web app has been updated (unconfirmed) · Oct 24: @LuminaBench's tracker shows gemini-4-carbon and gemini-4-carbon-teamfood among the model references in Google Antigravity build 1.4.3 (one account's screenshot, unconfirmed; no Carbon id in OpenRouter or models.dev)

  Earlier reports (3)

  Oct 28: Google announced Gemini 4 Carbon, which now has its own hunt (gemini-4-carbon); this one keeps 4.1+ and Barium · Gemini 4 Argon shipped Oct 13; Business Insider reported Oct 9 that Google staff were testing newer Gemini 4 checkpoints codenamed Barium and Carbon · Oct 19: The Information's Stephanie Palazzolo says its newsletter has a scoop on Gemini 4 Carbon, one of the releases she expects in the next few weeks (she corrected 'this month' to that) · Oct 21: @Lentils80, quoted by @lyraxana, says Gemini 4 Carbon early access has started for partners and that it is being tested on LMArena (unconfirmed; Google's Gemini API Early Access Program page names no model, and no Carbon id is in Google's docs, OpenRouter or models.dev)
• Next Gemini Pro
  No date · Google stepped back on 3.5 Pro to focus on Flash (Sep 24); Kalshi runs a 'next Gemini Pro' market · armed for a 3.6-3.9 Pro id
• Gemini 4 Flash
  No date · Nov 9 18:15 UTC: @lyraxana says a gemini-4-hydrogen private early-access program has started; ids containing hydrogen go to the gemini-hydrogen hunt · Nov 10: a Google engineer's public side project maps flash to gemini-4-hydrogen and flashLite to gemini-4-helix ids (unconfirmed)

  Earlier reports (5)

  Google has not announced a Gemini 4 Flash; Flash is on 3.8 (Sep 2) while Gemini 4 shipped as Argon on Oct 13 · Oct 25: @thtbee_ says Gemini 4 Flash may be in grey testing for some users, and @LuminaBench reports a gemini-3.8-flash-router slug in Antigravity metadata; both unconfirmed · Oct 27: @White1637402 (a small account, ~1.5K followers) says Gemini 4 Flash has surfaced internally under the codename 'Hydrogen', relayed by @LuminaBench; @lyraxana says a very fast model (~300 tok/s) on LMArena is it; all unconfirmed, and Google has said nothing · Nov 4: @lyraxana says Gemini 4 Flash (Hydrogen) is being A/B tested in AI Studio and on LMArena; the post carries no screenshot of either, Google has said nothing, and no gemini-4-flash id is in OpenRouter or models.dev (19:30 UTC) · Nov 7: Google still has not announced a Gemini 4 Flash; the Gemini API changelog (newest entry Nov 6), models list and pricing page have none, and neither OpenRouter nor models.dev lists a gemini-4-flash id
• Gemini Flash Cyber
  Restricted — vuln-finding model; the current build is 3.8 Flash Cyber, gated behind the Fairwind Program (govs, critical infrastructure, maintainers); watching for public access
• Gemini Helix
  Rumored, not announced · Nov 10: a public GitHub commit (04:20 UTC) in a personal Docker project for Google's Antigravity, whose owner's profile says he works at Google, routes the flashLite tier to gemini-4-helix-medium, -high, -tiered and gemini-4-helix (fallback gemini-3.5-flash-lite) and the flash tier to gemini-4-hydrogen ids; its tests use the display name 'Gemini 4 Helix (Medium)' · flagged by @LuminaBench (19:45 UTC), who notes Helix breaks the element naming · a side project, not a Google source; Google has said nothing, and at 19:55 UTC no helix id is on the Gemini API models page or OpenRouter · this hunt fires on any gemini id containing helix
• Gemini Hydrogen
  Rumored, not announced · Nov 9 18:15 UTC: @lyraxana says a Gemini 4 Hydrogen (gemini-4-hydrogen) private early-access program has started and that release is expected soon; one account, no screenshot, and Google has said nothing · since Oct 27 accounts on X have called Hydrogen the codename of Gemini 4 Flash (see that entry); all unconfirmed · no hydrogen id on OpenRouter at 18:50 UTC · this hunt fires on any gemini id containing hydrogen · Nov 9 21:26 UTC: @lyraxana says Hydrogen will launch with a fourth thinking effort, xhigh, and posts a side-by-side against Gemini 3.8 Flash; still one account, Google silent · Nov 10: a public commit (04:20 UTC) in a Google engineer's personal Antigravity Docker project routes the flash tier to gemini-4-hydrogen-medium, -high, -tiered and gemini-4-hydrogen, and flashLite to gemini-4-helix ids (flagged by @LuminaBench; a side project, not a Google source)
• Nano Banana 3
  Not announced — no Google word or date · Nano Banana 2.1 (gemini-nano-banana-2.1) is Google's newest image model; Nano Banana Pro is gemini-3-pro-image (Gemini API, read Oct 9) · Oct 15 @lyraxana says Google has started GemPix 3, which they call the next Nano Banana Pro, at its first internal checkpoint (one account, unconfirmed, nowhere near a release)
• Next Gemini Omni Flash (1.3+)
  Unannounced — armed on the cadence the moment Omni 1.2 Flash shipped (Nov 5), not on a leak · Google's current video model is Gemini Omni 1.2 Flash · Oct 18: @lyraxana said Google is working on a Gemini Omni 1.5 with 15-second clips (one account, unconfirmed); 1.2 already makes 15-second clips
• Veo 4
  Not announced — no Google word or date · Oct 22 2026: Veo 3.1 is NO LONGER Google's current video model on the Gemini API. Its three preview ids shut down today and Google names gemini-omni-1.1-flash the replacement; Omni Flash has been GA since Aug 27. Veo 3.1 stays GA on Vertex as veo-3.1-generate-001. Corrected because the file contradicted ITSELF: this note (written Oct 9) and gemini-omni-flash-next's note each named a different model 'Google's current video model', which is checkable against the registry alone and needs no network. Search-grade on the shutdown date; ai.google.dev was not opened
