Act as an intelligent email triage agent. I will provide you with 20 email subjects and sender names from my inbox. For each email: (1) Assign a priority level — Urgent (needs response today), Normal (respond within 3 days), or Low (FYI / no response needed); (2) Identify the required action — Reply, Forward to [role], Archive, or Schedule meeting; (3) Draft a one-sentence reply template for any email marked Urgent. Output as a structured table: Subject | Sender | Priority | Action | Draft Reply. At the end, list all Urgent items again in a single prioritised action list I can work through top-to-bottom.
Review the following Node.js Express API endpoint for security vulnerabilities and performance issues. For security: check for SQL injection exposure (parameterised queries vs. string concatenation), missing input validation, unprotected routes (missing auth middleware), sensitive data in logs or error responses, and missing rate limiting. For performance: identify synchronous operations that should be async, missing database query indexes (infer from query patterns), N+1 query patterns, and missing response caching opportunities. Output: a prioritised issue list (Critical / High / Medium / Low), each with the exact line or code block, the problem, and a corrected code snippet. [paste code below]
I am uploading an image of a consumer product and its packaging. Analyse the following: (1) Brand identity — describe the visual language, colour palette, typography style, and the emotional register they communicate; (2) Target audience inference — based on visual cues alone, who does this product appear to be targeting?

A logistics company operates 340 delivery vehicles across 12 cities. Fuel represents 38% of their variable operating cost. Diesel prices have increased 22% over the last 18 months. The company is evaluating three options: (A) Transition 30% of the fleet to electric vehicles over 24 months at $85,000 per vehicle, financed at 6.2% over 5 years; (B) Implement a route optimisation software at $12,000/month that the vendor claims reduces fuel consumption by 14%; (C) Do nothing and pass the cost increase to customers, risking a projected 8% churn among price-sensitive accounts. Show your reasoning step by step. Calculate the 3-year net cost or saving for each option under realistic assumptions. State your assumptions explicitly. Recommend one option and explain the two strongest objections to your recommendation.
Write a 12-minute podcast script (approximately 1,800 words) for a tech interview show. Guest: a fictional CTO of a mid-stage AI startup.

Understanding where Gemini 3.5 Flash leads helps you pick the right model for each task:
| Model | Speed | Agentic | Best For |
|---|---|---|---|
| Gemini 3.5 Flash (Google) ★ | 4× faster — leading | Best-in-class | Agentic workflows, coding, long-context, multimodal |
| Gemini 4 (Google) | Slower | Excellent | Maximum reasoning depth, research, science |
| GPT-5.5 (OpenAI) | Fast | Strong | Chat-based coding, creative writing, OpenAI ecosystem |
| Claude (Anthropic) | Moderate | Strong | Long documents, nuanced writing, code review |
| Gemini 3.5 Pro (Google) | Moderate | Excellent | Coming next month — deeper reasoning than 3.5 Flash |
★ Gemini 3.5 Flash is the default Gemini app model as of May 2026. Available via Gemini API, Google AI Studio, and Android Studio. Gemini 3.5 Pro expected June 2026.
Gemini 3.5 Flash is Google's latest AI model, announced at Google I/O on May 19, 2026. It is designed to combine frontier-level intelligence with low-latency execution — Google describes it as their first model to deliver 'frontier intelligence with action.' It outperforms Gemini 3.1 Pro on complex coding and agentic benchmarks while generating output tokens four times faster. Gemini 3.5 Flash is now the default model powering the Gemini app and is available via the Gemini API and Google AI Studio. It accepts text, image, audio, and video inputs.
Gemini 3.5 Flash is optimised for three use cases where speed + intelligence both matter: (1) Agentic workflows — multi-step tasks where the model takes real-world actions (browsing, calling tools, generating structured outputs); (2) Complex coding — it outperforms Gemini 3.1 Pro on coding benchmarks, making it particularly strong for code generation, review, and debugging tasks; (3) Long context reasoning — the model handles very long input documents (research papers, contracts, codebases) with strong comprehension and extraction accuracy. It also supports multimodal inputs, making it effective for analysing images, audio, and video in combination with text instructions.
Gemini 3.5 Flash responds well to structured, detailed prompts that specify the goal, the format of the expected output, and any constraints. For agentic tasks: describe the workflow as numbered steps and specify what tools the model should use or assume it has access to. For coding: describe the exact stack, version numbers, requirements, and edge cases up front. For long-document analysis: specify which sections to focus on and what format you want the output in — tables, bullet points, or prose. For multimodal: describe what you're uploading and ask specific analytical questions rather than open-ended ones. Always end with an explicit output format instruction (table, numbered list, markdown, JSON) — it significantly improves consistency.
Gemini 3.5 Flash and Gemini 4 serve different positions in Google's model lineup. Gemini 4 is Google's top-tier research and capability model — the most intelligent option for tasks requiring maximum reasoning depth, creative quality, or scientific complexity. Gemini 3.5 Flash is Google's optimised production model — it delivers performance close to a large frontier model at much lower latency and cost, making it better for real-time applications, high-volume API use, and agentic systems where response speed is critical. For day-to-day AI workflows, Gemini 3.5 Flash is typically the better choice; for complex reasoning tasks where speed is not a constraint, Gemini 4 leads.
Gemini 3.5 Flash is available through several channels: (1) Gemini app — it is now the default model for most interactions in the Gemini consumer app at gemini.google.com; (2) Gemini API — accessible via Google AI Studio and the Gemini API with a Google account, with a free tier and pay-per-use pricing; (3) Google AI Studio — the developer environment for testing and prototyping; (4) Android Studio — Google has integrated Gemini 3.5 Flash as the primary assistant model in its Android development environment. API pricing for Gemini 3.5 Flash is lower than flagship models — it is designed for production workloads where cost-per-query matters.
For coding tasks, the best model depends on the specific task type. Gemini 3.5 Flash leads on agentic coding workflows — tasks where the model must reason across large codebases, use tools, and take multi-step actions. Its four-times faster output speed is a practical advantage for interactive development sessions. GPT-5.5 (OpenAI) leads on chat-based code iteration and has strong integration with the OpenAI tooling ecosystem. Both models handle standard code generation and debugging at a high level. The most reliable approach for coding is to use the model best integrated with your IDE or development environment — Gemini 3.5 Flash has a native advantage in Android Studio and Google's toolchain.
