Gemini 1.5 Flash
A lighter, faster, cheaper Gemini model launching in the API on May 14, 2024.

Gemini 1.5 Pro with 2M token context
Gemini 1.5 Pro with a 1M token context window for Advanced subscribers, plus 2M token window in private developer preview.
The 2M context window opened to all developers on June 27, 2024, six weeks after I/O. Now standard across Gemini 1.5/2.x Pro.
Among the fastest-shipped I/O 2024 announcements.
Gemini API context caching
Cache repeated context to drastically reduce input-token cost.
Launched in Gemini API and Vertex AI in June 2024. By 2026 cache reads cost ~10% of input tokens on Gemini 2.5+.
Gemini in Workspace (Gmail Q&A, Docs help)
Gemini 1.5 Pro features inside Gmail, Docs, Drive, Slides, Sheets for paying users.
Shipped for paid Workspace and Google One AI Premium customers. Later (January 2025) Google removed the upcharge and bundled most Gemini features into standard Workspace plans.
Gemini Live (mobile conversational AI)
Mobile-first conversational Gemini experience with 10 natural voices, hinted at via Project Astra demo.

Gemini side panel in Gmail, Docs, Drive, Sheets, Slides

Helpful Content System merged into core ranking
The standalone helpful content classifier folded into Google's core ranking signals.
Rolled out as part of the March 2024 core update (before I/O), reiterated at I/O. Many independent publishers reported catastrophic traffic losses lasting into 2025–2026.
Defining cause of the 2024 'small publisher apocalypse' narrative on HN.
Imagen 3 (text-to-image model)
Highest-quality Google image model with photorealism and improved text rendering.
Opened in ImageFX (US) August 2024, then expanded to Gemini app, Gemini API, and Vertex AI through Q4 2024.
NotebookLM Audio Overviews (podcast generation)
Early prototype: turn uploaded sources into a podcast-style conversation between two AI hosts.
Shipped publicly September 2024, became one of Google's surprise viral hits. Interactive Audio Overviews (December 2024), 50+ languages (April 2025), new formats (September 2025).
Arguably the most-loved I/O 2024 product launch.
PaliGemma (open vision-language model)
Google's first open vision-language model for visual Q&A and captioning.
Released May 14, 2024 (day of I/O). PaliGemma 2 with 3B/10B/28B variants followed December 2024; PaliGemma 2 mix in 2025.

Trillium (6th-gen TPU)
Sixth-generation TPU with 4.7x peak compute per chip vs TPU v5e and 67% better energy efficiency; on Google Cloud 'late 2024'.
Hit preview in October 2024 and went GA in December 2024 — bang on the promised timing.
Trillium TPUs powering Anthropic & external customers
Trillium pitched as the substrate for next-gen frontier model training, including external customers.
Anthropic publicly committed to using Trillium TPUs at scale through 2024–2025; Trillium also powered Google's own Gemini 2.x training. External availability shipped with Trillium GA in December 2024.
Veo (text-to-video model)

Shipped September 25, 2024 with Pixel Watch 3 and Galaxy Watch 7 / Ultra. Older Pixel Watch 1 and 2 got it in November 2024.
Shipped late 2
Gemini-generated movie/TV descriptions in Google TV
Gemini auto-fills missing show/movie descriptions and translates them, implied 'later this year' (2024).
Slipped past 2024 — broader Gemini-on-TV experiences previewed at CES 2025 and the core auto-description feature only meaningfully appeared in early 2025.
~8 months after I/O 2024 and past the implied within-year timing.
Lyria (music generation model)
DeepMind's music model powering Music AI Sandbox.
Lyria stayed mostly behind-the-scenes through 2024. A consumer-facing Lyria 3 rolled out in the Gemini app in February 2026, followed by Lyria 3 Pro in March 2026 (full 3-minute tracks).
Almost two years before consumers got hands-on access.
Scaled back 9
AI Overviews in Google Search
AI Overviews (formerly SGE) rolling out to all U.S. users that week, expanding to one billion people by year-end.
Shipped on time, then immediately drew ridicule for telling users to put glue on pizza and eat rocks. Google quietly cut AI Overview frequency from ~27% to ~11% of queries within weeks, restricted health queries, and added guardrails. Still live but smaller scope than promised.
The single most-mocked Google launch of 2024.
AI-organized search results pages
AI-categorized results pages for restaurants, recipes, movies and music — 'starting with dining and recipes in the US this week'.
Briefly appeared in Search Labs for some US users, then quietly de-emphasized in favour of the AI Overviews + AI Mode direction in 2025. Never became the default Search experience as the keynote framing implied.
Eclipsed by AI Overviews fallout and the later AI Mode pivot.
Ask Photos (Gemini-powered Google Photos search)
Gemini in Google Photos for natural-language search of your library, launching 'this summer' (summer 2024).
Slipped: early-access waitlist opened September 2024, broader rollout pushed to 2025. Google paused the rollout in June 2025 over quality issues, then resumed it later that month. Capability also narrower than the keynote demo suggested.
Missed promised 'summer 2024' GA by ~a year and had to be paused mid-2025 for quality — less than promised on both timing and capability.
Gemini on Pixel Buds Pro 2 / wearables
Hands-free Gemini conversations through earbuds previewed in the Project Astra direction.
Pixel Buds Pro 2 shipped August 2024 with Gemini integration; conversational/Live support on earbuds rolled out incrementally through 2025 but remained more limited than the fluid Astra demo.
Hardware shipped; the seamless Astra-grade earbud experience did not.
Geospatial AR content in Google Maps
AR experiences in Maps, piloting in Singapore and Paris later in 2024.
Paris pilot launched July 2024 with Ubisoft + Google Arts & Culture. Singapore content followed. Remained a small partner-led pilot — never broadened materially.
Barely talked about after launch.
Google Cast for cars (Android Automotive, Rivian)
Cast video from phone/tablet to car displays, launching first on Rivian/Android Automotive.
Rolled out to Rivian via OTA in 2024; broader Android Automotive support remained limited through 2025.
Music AI Sandbox (with YouTube)
DeepMind+YouTube tool suite for AI music generation, demoed with Wyclef Jean, Justin Tranter, Marc Rebillet.
Limited rollout to selected artists only; 'broader access' in 2025 still meant invited musicians. Never opened to the general public despite the broad keynote framing.
Pitched as a broader creative tool but remains artist-invite-only as of 2026.
Project Astra (universal multimodal AI assistant)
A 'universal AI agent' demoed with a phone camera and prototype glasses understanding the world in real time.
Remained a research prototype. Capabilities (live video, screen share, memory) were folded into Gemini Live starting April 2025. Glasses still in trusted-tester program in 2026; no consumer Astra product.
The viral demo was the splashiest I/O 2024 moment — but the cohesive 'Astra' product never shipped as such.
VideoFX (Veo-powered Labs tool with Storyboard)
Labs tool to turn text into video clips, with a Storyboard mode for scene-by-scene iteration plus music.
Initial Storyboard feature was cut before public release; VideoFX shifted to single-video generation only. Wider access came via Veo 2 in December 2024.
The promised Storyboard mode never shipped publicly.
Rebranded 3
LearnLM (education-tuned model family)
Family of Gemini-based models fine-tuned for education, integrated into Search, YouTube, Classroom.
Available in AI Studio as an experimental model. At I/O 2025, Google folded LearnLM capabilities directly into Gemini 2.5 — no more standalone LearnLM listing.
Now part of mainline Gemini rather than a separate model.
Multi-step reasoning, meal & trip planning in Search
Multi-step reasoning, meal plans and trip plans available in Search Labs, with date-night and workout plans coming later in 2024.
Launched in Search Labs for U.S. English users in May 2024. The standalone planning tools were largely subsumed into the broader AI Mode launched March 2025.
Effectively absorbed into AI Mode in 2025.
Project IDX (browser dev environment)
Browser-based development environment, now public.
Renamed to Firebase Studio at Google Cloud Next on April 15, 2025; existing IDX workspaces continue to function under the new brand.
Vapor 1
Illuminate (research papers to AI podcasts)
Experimental tool turning research papers into AI-narrated audio conversations.
Available as a free Labs experiment with limited scope (primarily arXiv CS papers). Effectively cannibalised by NotebookLM's Audio Overviews. Still 'experimental' two years later with no visible roadmap or graduation from Labs.
Two years stuck in Labs with no meaningful progress — fails the 12-month public-progress bar.
