Gemini (model family)

Generally Available

Google DeepMind's frontier, natively multimodal LLM family spanning Pro, Flash and Flash-Lite tiers plus Deep Think reasoning. As of Oct. 15, 2026 the public frontier model is Gemini 4 Argon (gemini-4-argon), opened Oct. 13 to the paid API, Gemini for business, Ultra, and Pro and Ultra app users. The high-volume workhorse remains Gemini 3.8 Flash, with Gemini 3.8 Live and 3.8 Live Extended Thinking, Gemini 3.5 Flash-Lite, Gemini 3.1 Pro / 3.1 Deep Think, Gemini Omni, and a Fairwind-gated 3.8 Flash Cyber variant. Reuters and Bloomberg reported on Sept. 30, 2026 that Google no longer plans to release Gemini 3.5 Pro. DeepMind's Pro page presents Gemini 3.1 Pro.

Upcoming milestones5

Announced next steps from Google DeepMind that mention Gemini (model family).

  1. 2026

    Ship Gemini 3.5 Pro

    Target2026 (no confirmed date)

    Complete and launch Gemini 3.5 Pro after it slipped past the I/O 2026 June target, a widely reported July 17 date, and remaining undated through the September 2 Gemini 3.8 Flash launch and the September 15 Gemini 3.8 Live launch. DeepMind's models page still labels 3.5 Pro as coming soon as of September 19, 2026, with Gemini 3.1 Pro remaining the listed Pro option and no API identifier, pricing or model card published. Reported causes have included coding-benchmark shortfalls, hallucination and reliability problems. New operational lead Koray Kavukcuoglu's mandate is to ship faster and close the gap with Anthropic and OpenAI. Gemini 4's pre-training run continues in parallel with no disclosed timeline.

  2. 2026-2027

    Complete Gemini 4 pre-training

    Advance Google's next frontier model generation, Gemini 4, which began its most ambitious pre-training run yet on July 21, 2026 and runs on Google's Ironwood TPUs. Sundar Pichai told analysts on the Q2 2026 earnings call that Gemini 4 needs a larger base model to compete at the frontier, with coding and autonomous agents as stated priorities. As of September 14, 2026 Google has still not confirmed a release date or pre-training completion; Kavukcuoglu said in early September the run is going well, without a window. Outside estimates citing Google's past roughly six-month release cadence continue to point to a possible late-2026 window, but post-training, safety evaluation and product testing could push public availability into 2027.

  3. 2026-2030

    Advance world models and the path to AGI

    Extend Gemini Omni and the Veo/Genie world-model stack toward richer physical simulation, while pursuing the next Gemini generation (Gemini 4, in pre-training since July 21, 2026) on Google's Ironwood TPUs - with Hassabis projecting AGI around 2030 (possibly 2029). Gemini Omni 1.1 Flash went generally available on August 27, 2026 with 4K finishing and scene extension, and Gemini 3.8 Live shipped September 15, 2026 as a real-time audiovisual dialogue surface. An August 10, 2026 Fortune investigation into the causes of Hassabis's step-back as CEO cited low morale, a multi-year talent exodus and repeated model delays as headwinds to that roadmap; DeepMind has since also moved a roughly 90-person AI-responsibility (frontier-risk) team out to Google's Global Affairs organization (effective early September 2026) and begun piloting double-blind third-party evaluations of a Gemini Flash Lite model (announced Aug 27, 2026) as the lab reorganizes around Koray Kavukcuoglu.

  4. Fall 2026

    Scale Project Astra into a universal assistant

    Fold Project Astra's real-time perception, memory and tool-use research into shipping surfaces rather than a standalone product: Gemini Live in the Gemini app (now including Gemini 3.8 Live, shipped Sept 15, 2026), the agentic Gemini Spark assistant (initially AI Ultra-subscriber exclusive), and Android XR smart glasses (audio-only and display variants developed with Gentle Monster and Warby Parker), which Google and Samsung targeted for a Fall 2026 launch at I/O 2026. Samsung's August 3, 2026 Galaxy Unpacked still pointed to a fall launch in select markets with no exact date or price. As of Sept 17, 2026 the Fall 2026 window is unchanged, with pricing (expected in the $600-900 range) and an exact launch date still undisclosed.

  1. Google opens Gemini 4 Argon to paid users

    Google made Gemini 4 Argon available on Oct. 13 through the paid Gemini API, Gemini for business, and the Gemini app and AI Mode for Google AI Pro and Ultra subscribers, after a Sept. 30 rollout limited to Fairwind cyber defenders. Introductory API pricing is $2 per million input tokens and $10 per million output tokens through Nov. 30, then $4 and $20. Google said the public model has a 1 million token input-output limit and that Fairwind access is expanding to hundreds more partners.

  2. Google opens SynthID Detector to the public

    On Oct. 7, 2026 Google DeepMind opened SynthID Detector globally in English so anyone can check whether an image, video, or audio file was made with AI from Google or partners including OpenAI, Nvidia, and Kakao, with Apple listed as coming soon. Google said it has watermarked more than 180 billion images and videos and 240,000 years of audio since SynthID launched in 2023. The detector joins verification features in Search, the Gemini app, and Chrome.

  3. Google DeepMind opens Gemini 4 Argon to Fairwind defenders

    Google DeepMind announced Gemini 4 Argon on Sept. 30, a frontier model first rolling out to trusted cyber defenders in the Fairwind Program rather than to the public. Introductory API pricing is $2 per million input tokens and $10 per million output tokens, with a 1 million token output limit, up from 64,000, and a 77.9% score on DeepSWE v1.1. Paid API customers and Google AI Ultra subscribers are next, with no public date; Fairwind members and Google internal teams get a version without cyber guardrails.

  4. Trump restates he will not stifle AI as executives meet at White House

    President Donald Trump and House Speaker Mike Johnson scheduled a 12:30 p.m. Eastern White House East Room lunch on September 29, 2026 with AI company executives. OpenAI, Google and Palantir spokespeople told CBS News that President Greg Brockman, CEO Sundar Pichai and CEO Alex Karp are attending; Anthropic CEO Dario Amodei is expected per a source familiar with his plans, Nvidia CEO Jensen Huang per a source familiar with his plans, and Alphabet confirmed Pichai to CNBC. Earlier Tuesday Trump unveiled America.gov, which a White House official told NBC News uses Gemini and Grok, and said he will not stifle AI growth; Johnson has said the United States does not need a development moratorium. Coverage reviewed had no White House readout of new rules. A White House guest list and official also named Meta CEO Mark Zuckerberg, Tesla and SpaceX CEO Elon Musk, Amazon founder Jeff Bezos, Microsoft CEO Satya Nadella and AMD CEO Lisa Su among the broader group.

  5. Gemini hacked three companies in Irregular test

    Google said Gemini autonomously accessed three companies during a May cybersecurity evaluation by Irregular, the first known case of a Google model carrying out such a breakout. Heather Adkins, Google vice president of security engineering, told the BBC the model found public information online and guessed credentials to reach websites it thought were in scope, then stopped in each instance; Google notified the three entities and worked with Irregular on testing-process changes. Irregular said it informed Google and the affected entities in July and that known issues on its side were remedied weeks ago; Reuters said similar Irregular-linked incidents were disclosed by Meta, Anthropic, and OpenAI.
