Google releases three new Gemini models — but no 3.5 Pro

Google突然发布了三款新AI模型，但大家最期待的“大哥大”Gemini Pro却缺席了。这次推出的三款模型分别是：主力干将Gemini 3.6 Flash，编程和多模态能力更强，还比上一代便宜了将近两成；性价比之王3.5 Flash-Lite，专为预算敏感的场景打造；还有一个特别版的3.5 Flash Cyber，专门用来找网络安全漏洞，不过只面向政府和大企业开放测试。简单来说，Google这次的重点是把模型做便宜、做快、做专业，让那些想大规模使用AI的公司能省成本、提效率。但眼瞅着对手OpenAI和Anthropic一个接一个放大招，自家的旗舰模型却迟迟不露面——内部测试没达标，发布时间一拖再拖，这难免让开发者有点着急。好在官方表示“快来了”，而且下一代Gemini 4的大规模预训练已经启动。对普通人来说，以后用AI写代码、做图、处理复杂任务，成本更低、响应更快；网络安全这块，有专门的AI帮忙查漏洞，企业数据会更有保障。但如果你想用最聪明的AI处理高难度问题，可能还得再等等。

On Tuesday, Google DeepMind released Gemini 3.6 Flash, 3.5 Flash-Lite, and 3.5 Flash Cyber. Gemini 3.6 Flash is Google’s “workhorse model” that promises improved capabilities in coding, knowledge work, and multimodal performance while reducing token usage by up to 17%, making it cheaper than its predecessor 3.5 Flash. Gemini 3.5 Flash-Lite is the most cost-effective model in the class, and 3.5 Flash Cyber is a specialized model that was fine-tuned for finding and fixing cybersecurity vulnerabilities at a decent price point. This model will be exclusively available to governments and trusted partners as part of a limited access pilot program, according to Google. Google says the focus on these releases is to deliver efficiency, latency, and reliability to customers that are building AI agents at scale. The launch is notable not just for what Google shipped — cheaper, faster models optimized for coding, efficiency, and cybersecurity — but also for what it didn’t. The update doesn’t include the long-anticipated update to Google’s flagship model, Gemini Pro, which was last updated in February. In the time since that launch, OpenAI has released GPT-5.5 and begun rolling out GPT-5.6, while Anthropic has launched Claude Opus 4.8 and Claude Sonnet 5 and has expanded access to its frontier Fable 5 model, highlighting the intense release pace of the rival labs. Google teased the release of Pro as part of the 3.5 Flash release in May, saying the Pro version was “already being used internally, and we look forward to rolling it out next month.” Last week, Bloomberg reported that Google was facing internal delays in launching the 3.5 Pro as it struggled to meet internal performance goals. Gemini Pro models are generally Google’s highest-capability offerings for complex reasoning and coding tasks, while Flash models prioritize lower cost and faster response times for production applications. var playerInstance_jwplayer_6a6019f787fa5 = jwplayer( "jwplayer_6a6019f787fa5" ); playerInstance_jwplayer_6a6019f787fa5.setup({ playlist: "https://cdn.jwplayer.com/v2/media/DxHIIVx3", }); Google DeepMind product lead Logan Kilpatrick said Tuesday that the company is currently testing Gemini 3.5 Pro with partners and hopes to “land soon.” He also noted that the team has started its most ambitious pre-training run yet for Gemini 4.
