We're excited to share that Felo AI now supports GPT-5.1, OpenAI's latest flagship model released on November 12, 2025. This means you can now experience one of the most advanced AI models available—completely free on our platform.
What Makes GPT-5.1 Different?
GPT-5.1 represents a significant shift in OpenAI's approach to AI development. Rather than simply chasing benchmark scores, this update focuses on making AI interactions feel more natural, conversational, and genuinely helpful. The release includes two core models working together to deliver better results across different types of tasks.
Two Models, Smarter Routing
GPT-5.1 consists of two specialized models:
GPT-5.1 Instant is optimized for everyday conversations and quick responses. It features a warmer, more conversational tone and significantly improved instruction-following capabilities. What sets it apart is its adaptive reasoning mechanism—the model can dynamically adjust how much "thinking time" it needs based on the complexity of your question. For simple queries, you get fast responses. For challenging problems, it takes more time to ensure accuracy.
GPT-5.1 Thinking is designed for complex reasoning tasks that require deeper analysis. It's more efficient than its predecessor, responding about twice as fast on simpler tasks while taking up to twice as long on the most complex problems to ensure thorough, well-reasoned answers. The explanations it provides are also clearer and easier to understand, with less jargon and more context.
GPT-5.1 Auto intelligently routes your queries to the most appropriate model based on the complexity and nature of your request. Most of the time, you won't need to think about which model to use—the system handles it automatically.
Real Improvements in Everyday Use
The changes in GPT-5.1 aren't just technical—they translate to noticeable improvements in how the AI communicates.
More Natural Conversations: The default tone is warmer and more empathetic. When you're stressed or facing a challenge, GPT-5.1 Instant responds with understanding before diving into solutions. It feels less like interacting with a tool and more like having a conversation with someone who actually gets what you're asking.
Better at Following Instructions: One of the most practical improvements is instruction adherence. In tests, GPT-5.1 Instant consistently followed specific user instructions across multiple conversation turns, where previous models would drift away from the original request. This means less frustration when you need the AI to maintain a particular format or style.
Clearer Technical Explanations: GPT-5.1 Thinking excels at explaining complex concepts in accessible language. Instead of drowning you in technical terminology, it provides context, uses analogies, and structures information in ways that are easier to grasp.
Enhanced Performance Across Key Areas
Thanks to adaptive reasoning, GPT-5.1 Instant shows measurable improvements in mathematics and programming tasks while maintaining its speed advantage. The model dynamically allocates computational resources where they're needed most—giving you both efficiency and accuracy.
How to Use GPT-5.1 on Felo AI
Getting started with GPT-5.1 on Felo is straightforward. We offer two convenient ways to access it:
Method 1: Through Felo AI Search
- Visit the Felo AI homepage at felo.ai
- Click to open the Pro models section
- Select "More Models" from the dropdown menu
- Choose the GPT-5.1 model from the list
Method 2: Through LLM Playground
For a more hands-on experience, you can access GPT-5.1 directly through our LLM Playground:
- Navigate to playground.felo.ai
- Select GPT-5.1 from the model options
- Start experimenting with different prompts and use cases
Both methods give you full access to GPT-5.1's capabilities, whether you're conducting research, creating content, solving complex problems, or just having an intelligent conversation.
Why This Matters for Felo Users
At Felo AI, our mission is to help you search the world in your own language and transform that information into actionable insights. By integrating GPT-5.1, we're expanding the toolkit available to you for knowledge work and creative projects.
Whether you're using Felo to generate presentations through Felo Slides, conduct multilingual research, create mind maps, or produce detailed reports, having access to GPT-5.1 means you can choose the right AI model for your specific task. Our platform supports multiple leading language models, and GPT-5.1 adds another powerful option to your arsenal.
What Users Should Know
OpenAI has been transparent that GPT-5.1 prioritizes user experience over raw performance metrics. The focus is on making AI that feels more human, more reliable, and more genuinely useful in day-to-day applications. This approach has received mixed reactions—some users appreciate the warmer interaction style, while others prefer the more direct, tool-like approach of previous versions.
The good news is that you can try it yourself and decide what works best for your needs. Felo's multi-model support means you're not locked into any single approach.
Looking Forward
The addition of GPT-5.1 support is part of our ongoing commitment to providing Felo users with access to the best AI technologies available. As we continue to expand our platform—from our AI search engine to content creation tools, AI agents, and enterprise solutions—we'll keep integrating cutting-edge models that help you work smarter and more efficiently.
We believe AI should break down barriers, not create them. That's why we're making GPT-5.1 accessible to all Felo users, regardless of whether you're on our free plan or Pro subscription. Everyone deserves access to powerful AI tools that can help them learn, create, and solve problems.
Try It Today
The best way to understand what GPT-5.1 can do is to experience it yourself. Head over to felo.ai or our LLM Playground and give it a try. Test it with complex reasoning tasks, see how it handles nuanced conversations, or use it alongside our other tools to create presentations, reports, or mind maps.
We're excited to see what you'll build with it.
