Google releases three new Gemini models — but no 3.5 Pro

谷歌发布三款全新 Gemini 模型，但未见 3.5 Pro

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.

周二，Google DeepMind 发布了 Gemini 3.6 Flash、3.5 Flash-Lite 和 3.5 Flash Cyber。Gemini 3.6 Flash 被谷歌称为“主力模型”，它承诺在编码、知识工作和多模态性能方面有所提升，同时将 Token 使用量减少了多达 17%，使其成本低于前代产品 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.

Gemini 3.5 Flash-Lite 是该系列中性价比最高的模型，而 3.5 Flash Cyber 则是一款专门针对网络安全漏洞发现与修复进行微调的专业模型，且价格合理。据谷歌称，该模型将作为有限访问试点计划的一部分，仅向政府和受信任的合作伙伴提供。

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.

谷歌表示，此次发布的核心目标是为大规模构建 AI 智能体的客户提供高效、低延迟和可靠的服务。此次发布不仅因谷歌推出的产品（针对编码、效率和网络安全优化的更便宜、更快的模型）而引人注目，更因其未发布的产品而备受关注。此次更新并未包含人们期待已久的谷歌旗舰模型 Gemini Pro 的更新，该模型上一次更新还是在二月份。

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.

自那次发布以来，OpenAI 已经发布了 GPT-5.5 并开始推出 GPT-5.6，而 Anthropic 则推出了 Claude Opus 4.8 和 Claude Sonnet 5，并扩大了其前沿模型 Fable 5 的访问权限，这凸显了竞争对手实验室激烈的发布节奏。

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.

谷歌曾在五月份发布 3.5 Flash 时预告过 Pro 版本的发布，称 Pro 版本“已经在内部使用，我们期待下个月推出”。上周，彭博社报道称，由于难以达到内部性能目标，谷歌在推出 3.5 Pro 时面临内部延期。

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. 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.

Gemini Pro 模型通常是谷歌针对复杂推理和编码任务提供的最高能力产品，而 Flash 模型则优先考虑生产应用中的低成本和更快的响应时间。Google DeepMind 产品负责人 Logan Kilpatrick 周二表示，公司目前正在与合作伙伴测试 Gemini 3.5 Pro，并希望“尽快落地”。他还指出，团队已经开始了迄今为止最雄心勃勃的 Gemini 4 预训练工作。
