Google is using its annual developer conference to showcase what the company is calling its lightest and most efficient artificial intelligence models.
At Google I/O on Tuesday, the company announced Gemini 1.5 Flash, the newest addition to the Gemini model series.
“We heard from developers that they wanted something faster and even more cost effective,” said Demis Hassabis, CEO of Google DeepMind, in a press briefing.
The unveiling comes as tech companies increasingly refocus their product development and rollouts around generative AI, which is of particular importance to Google because the new tools give consumers more advanced and creative ways to access online information compared to traditional web search.
OpenAI on Monday launched a new AI model and desktop version of ChatGPT, along with a new user interface. The new model, GPT-4o, is twice as fast as GPT-4 Turbo and half the cost, the company said.
Google also announced an improved Gemini 1.5 Pro model, which has the ability to make sense of multiple large documents — 1,500-pages total — or summarize 100 emails, according to a vice president working on Gemini.
Gemini 1.5 Pro will soon be able to handle an hour of video content, or codebases with more than 30,000 lines, Hsiao said.
“You can quickly get answers and insights about dense documents, like figuring out the details of the pet policy in your rental agreement or comparing key arguments of multiple long research papers,” Hsiao said.
OpenAI’s latest upgrade, announced this week, brings with it improved quality and speed of ChatGPT for 50 different languages. It will also be available via OpenAI’s application programming interface (API), allowing developers to begin building applications using the new model immediately, executives said.
With 35 languages, Google says Gemini 1.5 Pro has a 2 million token window, which measures context and indicates how much information the model is able to process at once. The new model has improved local reasoning, planning and image understanding, company executives said.
“It offers the longest context window of any foundational model yet,” Alphabet CEO Sundar Pichai said in the press briefing. At the event, he gave an example of a parent asking Gemini to summarize all recent emails from their child’s school.
Gemini 1.5 Pro will initially be available for testing in Workspace Labs. Gemini 1.5 Flash will be available for testing and in Vertex AI, which is Google’s machine learning platform that lets developers train and deploy AI applications.

Tesla shares have dropped 7% from Friday’s closing price of $323.63to the $300.71 close on Tuesday ahead of the company’s second-quarter deliveries report.
Wall Street analysts are expecting Tesla to report deliveries of around 387,000 — a 13% decline compared to deliveries of nearly 444,000 a year ago, according to a consensus compiled by FactSet. Prediction market Kalshi told CNBC on Tuesday that its traders forecast deliveries of around 364,000.
Shares in the electric vehicle maker had been rising after Tesla started a limited robotaxi service in Austin, Texas, in late June and CEO Elon Musk boasted of its first “driverless delivery” of a car to a customer there.
The stock price took a turn after Musk on Saturday reignited a feud with President Donald Trump over the One Big Beautiful Bill Act, the massive spending bill that the commander-in-chief endorsed. The bill is now heading for a final vote in the House.
That legislation would benefit higher-income households in the U.S. while slashing spending on programs such as Medicaid and food assistance.
Musk did not object to cuts to those specific programs. However, Musk on X said the bill would worsen the U.S. deficit and raise the debt ceiling. The bill includes tax cuts that would add around $3 trillion to the national debt over the next decade, according to an analysis by the Congressional Budget Office.
The Tesla CEO has also criticized aspects of the bill that would cut hundreds of billions of dollars in support for renewable energy development in the U.S. and phase out tax credits for electric vehicles.
Such changes could hurt Tesla as they are expected to lower EV sales by roughly 100,000 vehicles per year by 2035, according to think tank Energy Innovation.
The bill is also expected to reduce renewable energy development by more than 350 cumulative gigawatts in that same time period, according to Energy Innovation. That could pressure Tesla’s Energy division, which sells solar and battery energy storage systems to utilities and other clean energy project developers.
Trump told reporters at the White House on Tuesday that Musk was, “upset that he’s losing his EV mandate,” but that the tech CEO could “lose a lot more than that.” Trump was alluding to the subsidies, incentives and contracts that Musk’s many businesses have relied on.
SpaceX has received over $22 billion from work with the federal government since 2008, according to FedScout, which does federal spending and government contract research. That includes contracts from NASA, the U.S. Air Force and Space Force, among others.
Tesla has reported $11.8 billion in sales of “automotive regulatory credits,” or environmental credits, since 2015, according to an evaluation of the EV maker’s financial filings by Geoff Orazem, CEO of FedScout.
These incentives are largely derived from federal and state regulations in the U.S. that require automakers to sell some number of low-emission vehicles or buy credits from companies like Tesla, which often have an excess.
Regulatory credit sales go straight to Tesla’s bottom line. Credit revenue amounted to approximately 60% of Tesla’s net income in the second quarter of 2024.

Amazon founder Jeff Bezos unloaded more than 3.3 million shares of his company in a sale valued at roughly $736.7 million, according to a financial filing on Tuesday.
The stock sale is part of a previously arranged trading plan adopted by Bezos in March. Under that arrangement, Bezos plans to sell up to 25 million shares of Amazon over a period ending May 29, 2026.
Bezos, who stepped down as Amazon’s CEO in 2021 but remains chairman, has been selling stock in the company at a regular clip in recent years, though he’s still the largest individual shareholder. He adopted a similar trading plan in February 2024 to sell up to 50 million shares of Amazon stock through late January of this year.
Bezos previously said he’d sell about $1 billion in Amazon stock each year to fund his space exploration company, Blue Origin. He’s also donated shares to Day 1 Academies, his nonprofit that’s building a chain of Montessori-inspired preschools across several states.
The most recent stock sale comes after Bezos and Lauren Sanchez tied the knot last week in a lavish wedding in Venice. The star-studded celebration, which took place over three days and sparked protests from some local residents, was estimated to cost around $50 million.

The Google Doodle is Alphabet’s most valuable piece of real estate, and on Tuesday, the company used that space to promote “AI Mode,” its latest AI search product.
Google’s Chrome browser landing pages and Google’s home page featured an animated image that, when clicked, leads users to AI Mode, the company’s latest search product. The doodle image also includes a share button.
The promotion of AI Mode on the Google Doodle comes as the tech company makes efforts to expose more users to its latest AI features amid pressure from artificial intelligence startups. That includes OpenAI which makes ChatGPT, Anthropic which makes Claude and Perplexity AI, which bills itself as an “AI-powered answer engine.”
Google’s “Doodle” Tuesday directed users to its search chatbot-like experience “AI Mode”
AI Mode is Google’s chatbot-like experience for complex user questions. The company began displaying AI Mode alongside its search results page in March.
“Search whatever’s on your mind and get AI-powered responses,” the product description reads when clicked from the home page.
AI Mode is powered by Google’s flagship AI model Gemini, and the tool has rolled out to more U.S. users since its launch. Users can ask AI Mode questions using text, voice or images. Google says AI Mode makes it easier to find answers to complex questions that might have previously required multiple searches.
In May, Google tested the AI Mode feature directly beneath the Google search bar, replacing the “I’m Feeling Lucky” widget — a place where Google rarely makes changes.
