3.5 Flash: frontier performance for agents and coding

3.5 Flash：代理任务与编程的前沿性能

Gemini 3.5 Flash delivers intelligence that rivals large flagship models on multiple dimensions, at the speeds you have come to expect from the Flash series. It’s our strongest agentic and coding model yet, outperforming Gemini 3.1 Pro on challenging coding and agentic benchmarks like Terminal-Bench 2.1 (76.2%), GDPval-AA (1656 Elo) and MCP Atlas (83.6%), and leading in multimodal understanding (84.2% on CharXiv Reasoning). When looking at output tokens per second, it is 4 times faster than other frontier models. Landing in the top-right quadrant of the Artificial Analysis index, 3.5 Flash delivers frontier-level intelligence at exceptional speed — proving you no longer have to trade quality for latency. Gemini 3.5 Flash 在多个维度上提供了足以媲美大型旗舰模型的智能，并保持了 Flash 系列一贯的高速度。这是我们迄今为止最强大的代理和编程模型，在 Terminal-Bench 2.1 (76.2%)、GDPval-AA (1656 Elo) 和 MCP Atlas (83.6%) 等极具挑战性的编程和代理基准测试中表现优于 Gemini 3.1 Pro，并在多模态理解（CharXiv Reasoning 得分 84.2%）方面处于领先地位。在输出 Token 速度方面，它比其他前沿模型快 4 倍。在 Artificial Analysis 指数中，3.5 Flash 稳居右上象限，以卓越的速度提供前沿水平的智能——这证明您无需再为了低延迟而牺牲质量。

3.5 Flash: agentic tasks at scale

3.5 Flash：大规模代理任务

This balance of speed and performance makes 3.5 Flash ideal for tackling long-horizon agentic tasks. What used to take a developer days or an auditor weeks, 3.5 Flash can now help complete in a fraction of the time, often at less than half the cost of other frontier models. It rapidly plans, builds and iterates to solve real-world problems, whether it’s developing new applications, maintaining codebases or helping to prepare financial documents. 这种速度与性能的平衡使 3.5 Flash 成为处理长周期代理任务的理想选择。过去需要开发者花费数天或审计员数周才能完成的工作，现在 3.5 Flash 可以在极短时间内协助完成，且成本通常不到其他前沿模型的一半。它能快速规划、构建并迭代以解决现实世界的问题，无论是开发新应用、维护代码库，还是协助准备财务文档，都能游刃有余。

When coupled with the updated Antigravity harness, 3.5 Flash becomes a powerful engine for deploying collaborative subagents to tackle problems at scale for the most demanding use cases. Under supervision, it can reliably execute multi-step workflows and coding tasks while sustaining frontier performance. 当与更新后的 Antigravity 框架结合使用时，3.5 Flash 成为部署协作式子代理的强大引擎，能够为最严苛的应用场景解决大规模问题。在监督下，它可以在保持前沿性能的同时，可靠地执行多步骤工作流和编程任务。

3.5 Flash: real-world impact

3.5 Flash：现实世界的影响力

3.5 Flash’s real-world agentic capabilities are already driving meaningful progress for our developers and enterprises alike. In developing the 3.5 model series, we worked closely with industry partners to understand where toil and complexity arose in their workflows. Partners are seeing meaningful impact — from banks and fintechs automating multi-week workflows to data science teams unearthing insights amidst complex data environments. 3.5 Flash 的现实代理能力已经为我们的开发者和企业带来了实质性的进展。在开发 3.5 模型系列的过程中，我们与行业合作伙伴密切合作，深入了解他们工作流中繁琐和复杂之处。合作伙伴们已经看到了显著的影响——从银行和金融科技公司实现数周工作流的自动化，到数据科学团队在复杂数据环境中挖掘洞察。
