Google Launches Android Bench 2.0 with Long-Horizon Tasks, Agentic Evaluation
Google announced the release of Android Bench 2.0, an upgraded benchmark for evaluating large language models (LLMs) and coding agents on Android development tasks. The update introduces long-horizon tasks (LHTs) that simulate complex, multi-day engineering work, moving beyond simple bug fixes. Android Bench 2.0 also incorporates continuous scoring instead of binary pass/fail, providing a more nuanced assessment of model performance. Additionally, Google has begun agentic evaluations, pairing models with agents like GPT-5.6 Sol on Codex and Gemini 3.8 Flash on Google Antigravity to measure real-world workflow effectiveness. The leaderboard has been expanded with new models, including Gemini 3.8 Flash, OpenAI GPT-6, and Anthropic Fable 5.1, with OpenAI GPT-6 Astra achieving the highest pass rate of 28% on LHTs, compared to 91% on original tasks. This release reflects Google's commitment to improving AI-assisted Android development through more realistic and rigorous evaluation.
Major platform update from Google on AI agent evaluation methodology, directly impacting AI-assisted development for Android, relevant to AdTech/tech infrastructure for AI agents.

Google's Gemini 3.1 Pro Shatters Benchmark Records Again!
Google unveiled Gemini 3.1 Pro, the latest iteration of its large language model, releasing a preview and announcing a forthcoming general availability. Independent benchmark results cited by Google — including Humanity’s Last Exam and Mercor’s APEX system — show Gemini 3.1 Pro outperforming its predecessor, Gemini 3. Brendan Foody, CEO of AI startup Mercor, said the model reached the top of the APEX-Agents leaderboard. The update comes amid intensified competition in advanced LLMs from rivals such as OpenAI and Anthropic and highlights rapid improvements in models designed for agentic, multi-step reasoning and professional tasks.
Google Rebuilds Android Toolchain for AI Agents
Google has redesigned the Android development toolchain to optimize workflows for AI Agents, introducing three core components: Android CLI (a standardized agent-first command-line interface), Android Skills (SKILL.md modules packaging best-practice workflows), and the Android Knowledge Base (real-time authoritative docs accessible via CLI). The toolchain aims to reduce agents' environment-probing overhead, with Google's internal experiments claiming a 70%+ reduction in LLM token usage and roughly 3× faster completion for core development tasks. Android Skills follow the agentskills.io open standard and are agent-agnostic; the system integrates with Android Studio so CLI-provisioned projects open directly in the IDE. The release includes a small set of official skills and platform installers for multiple OSes.
