🚀 Introducing GPT 4.1 & GPT 4.1-mini: What’s New and How to Access Them
The two new models, GPT 4.1 and GPT 4.1-mini, are now accessible directly within ChatGPT’s interface. To find them, simply click on the model selection dropdown, then choose “More models.” Here, you’ll see both GPT 4.1 and GPT 4.1-mini listed among the options.
Once you select GPT 4.1, you’ll notice you have access to all the advanced tools ChatGPT offers, including the canvas feature for visual work. However, if you opt for GPT 4.1-mini, one tool—the canvas feature—is unavailable. This distinction points to the key difference between these models:
- GPT 4.1: Best suited for logic-heavy tasks like coding, data analysis, and any work that requires precise reasoning.
- GPT 4.1-mini: Optimized for speed and everyday tasks where quick, efficient responses are more important than deep logical reasoning.
These new models effectively replace the older GPT-4 mini versions (o4 mini and o4 mini high), which are now largely obsolete. GPT 4.1 and GPT 4.1-mini outperform those older mini models in both speed and accuracy.
🧠 Mastering Prompting for GPT 4.1: 13 Essential Tips
One of the biggest changes with GPT 4.1 is how you need to approach prompting. OpenAI released a detailed GPT 4.1 prompting guide, but it’s quite long and complex. To simplify things, I’ve distilled the essentials into thirteen actionable tips that will help you unlock the full potential of these new models:
- Be hyper-literal: GPT 4.1 is much more precise than previous versions. Specify exactly what you want without ambiguity.
- Repeat key prompts: For longer tasks, restate important instructions at both the beginning and end to keep the model focused.
- Use clear separators: Utilize markdown headers or XML tags to structure your input. Avoid JSON for long text as it tends to break.
- Force thinking mode: Always instruct the model to think step-by-step. Without this, it won’t naturally perform logical reasoning.
- Activate agent mode: This “beast mode” requires reminding the model to not stop until the task is 100% complete, use tools instead of guessing, and plan every step before taking action.
- Leverage the large context window: GPT 4.1 supports up to one million tokens, so try to use the full context for complex tasks—but avoid exceeding it as quality drops.
- Mix base knowledge with custom context: You can instruct the model to rely on its base knowledge, your custom context, or a combination of both for tailored responses.
- Structure your prompts: Include role and goal, instructions, reasoning steps, output format, and examples to guide the model effectively.
- Help it find information: For document-heavy tasks, ask the model to scan and filter relevant parts before proceeding.
- Avoid confusing patterns: Keep prompts straightforward and avoid ambiguous or contradictory instructions.
- Correct with clear fixes: When adjusting outputs, use a single, clean line of correction for better results.
- Use code frameworks: For coding tasks, provide frameworks or templates the model can work within.
- Remember GPT 4.1 is not a logic machine by default: It excels at logic but won’t use that ability unless explicitly instructed.
Think of GPT 4.1 like a Ferrari: if you keep it on the road with the right prompts, it’s a powerhouse. But if you don’t guide it precisely, you risk ending up somewhere unintended.
💡 Understanding When to Use Each ChatGPT Model
With so many models available, it’s crucial to know which one fits your needs best. Here’s a breakdown of the main models and their ideal use cases:
- GPT 4.1: Your go-to for coding, logical analysis, and tasks requiring high precision. Use it when you need deep reasoning and step-by-step thinking.
- GPT 4.1-mini: Fast and efficient for everyday queries and simple tasks where speed matters more than complex reasoning.
- O3 (GPT 3.5 Turbo): Best for planning and multi-step reasoning without needing strict instructions. It’s great for exploratory back-and-forth conversations and complex problem-solving.
- GPT 4.5: A creativity powerhouse, ideal for writing, brainstorming, and generating ideas. It sounds more human-like but may hallucinate more than other models.
- GPT 4.0: A solid all-rounder for most tasks, but personally, I use it less now that 4.1 and 4.5 are available.
- o4 mini and o4 mini high: These older mini models are now mostly obsolete and should be avoided in favor of GPT 4.1 and 4.1-mini.
Example: Using O3 for Advanced Planning
The O3 model is incredibly powerful for planning because it can think through multiple steps and continue working until the task is complete. For instance, I uploaded a photo of my old house and asked O3 to find its location. Without any additional context, it spent six minutes analyzing the image, searching the web, reasoning about the details, and cross-referencing data until it pinpointed the exact address by matching architectural features and landscaping with online listings.
This showcases O3’s unique ability to combine image analysis, web search, and logical reasoning in a continuous loop — perfect for complex planning and research tasks.
🛠️ Setting Up Your ChatGPT Projects for Maximum Efficiency
To really get the most out of these models, especially GPT 4.1, you should create specific projects tailored to your tasks. For example, I use ChatGPT to write my YouTube scripts. I provide detailed instructions about tone, length, and style, and upload previous scripts as project files so the AI understands what I expect.
Additionally, customize your ChatGPT persona by filling out the “Customize ChatGPT” section. Include your interests, values, preferences, and traits you want the AI to embody. This helps the model give responses aligned with your personality and goals.
🔗 Connecting Apps and Looking Ahead
Another exciting update is the ability to connect various external apps directly to ChatGPT. This integration opens up new automation possibilities. For example, with the upcoming MCP (Microsoft Copilot) integration and Google’s Gemini AI conference scheduled soon, we expect a wave of new features and enhancements to hit ChatGPT in the coming weeks.
Staying on top of these developments will help you leverage AI not just for answering questions but for automating workflows, managing data, and much more.
📋 Summary: Which ChatGPT Model Should You Use?
- GPT 4.1: Use for coding, logic, and analysis with precise, step-by-step prompts.
- GPT 4.1-mini: Use for quick, everyday tasks where speed is key.
- O3: Use for deep planning, reasoning, and multi-step problem solving.
- GPT 4.5: Use for creative writing, brainstorming, and idea exploration.
- GPT 4.0: General purpose but less preferred now.
- O4 mini & O4 mini high: Avoid these older models; they’re replaced by GPT 4.1 versions.
