A new era of AI innovation has arrived on the Giselle platform! We are thrilled to announce the official integration of OpenAI's groundbreaking GPT-5 series models: GPT-5, GPT-5 mini, and GPT-5 nano. This powerful new addition brings unparalleled intelligence, speed, and versatility to your AI workflows, and best of all, the GPT-5 mini and GPT-5 nano models are now available to all users, including those on our Free Plan!

As Giselle continues to evolve as your intuitive, no-code AI application builder, our commitment remains to empower you with the most advanced AI capabilities. The GPT-5 series represents a significant leap forward, designed to excel at complex reasoning, advanced coding, creative writing, and sophisticated multimodal understanding. It sets new benchmarks for performance while offering efficient solutions for a wide range of tasks.

Model-by-model highlights

Here's a quick comparison of the new GPT-5 series and other flagship OpenAI models available in Giselle:

Models Generate Text Input Image Web Search Reasoning Context Window Max Output Tokens Pricing (Input/Output per 1M tokens) Availability
gpt-5 ✅ ✅ ✅ ✅ (Highest) 400k tokens 128k tokens $1.25 / $10.00 Pro
gpt-5-mini ✅ ✅ ✅ ✅ (High) 400k tokens 128k tokens $0.25 / $2.00 Free
gpt-5-nano ✅ ✅ ❌ ✅ (Medium) 400k tokens 128k tokens $0.05 / $0.40 Free

Which one to choose?

Choosing the right GPT-5 model in Giselle depends on your specific needs:

  • GPT-5 (gpt-5) – The new flagship model for Pro Plan users. This is your go-to for the most challenging tasks, including advanced coding, complex reasoning, and "agentic" workflows. Its built-in expert-level intelligence and deeper reasoning engine make it exceptionally capable for multi-step problems, technical writing, and analyzing text, code, and images with precision. It also supports web search.

  • GPT-5 mini (gpt-5-mini) – A faster, more cost-efficient version of GPT-5, optimized for well-defined tasks. Available on the Free Plan, it balances intelligence, speed, and affordability while maintaining strong reasoning capabilities. It supports image inputs and web search, making it a versatile choice for many common use cases without a paid subscription.

  • GPT-5 nano (gpt-5-nano) – The fastest and most cost-effective model in the GPT-5 series. Available on the Free Plan, it's designed for high-throughput tasks like summarization and classification, providing quick and efficient performance. It supports text and image inputs but does not include web search functionality, making it ideal for tasks where external real-time data is not required.

While the GPT-5 series offers cutting-edge performance, Giselle continues to support other powerful OpenAI models to ensure you have the best tool for every job.

Why pair them with Giselle?

Giselle's visual, no-code platform is the perfect environment to harness the full potential of OpenAI's GPT-5 series:

1. Seamless Multimodal Integration

With Giselle's File Node and GitHub Vector Store Node, you can seamlessly feed diverse inputs—such as PDFs, images, and codes—into your GPT-5 workflows. This empowers you to build agents that excel at coding, mathematics, writing, health-related analysis, and visual recognition, enabling advanced insights and automation across a wide range of data formats within an intuitive visual environment.

2. Real-time Web Grounding (for GPT-5 & GPT-5 mini)

Leverage the Search grounding feature within the Generator Node to ensure your AI agents provide the most current and accurate information. This is particularly powerful when combined with GPT-5's advanced reasoning and the speed of GPT-5 mini, allowing for rapid, fact-checked responses based on real-time web data (note: GPT-5 nano does not support web search).

3. Efficient Workflow Automation

Giselle's intuitive node-based interface allows you to chain GPT-5 series models with other nodes, creating sophisticated, automated workflows. Whether it's automating code reviews, generating detailed reports, summarizing web articles, or extracting data from documents, the GPT-5 series' efficiency ensures your agents run smoothly and powerfully.

4. Accessibility for All

The availability of GPT-5 mini and GPT-5 nano on the Free Plan significantly lowers the barrier to entry for advanced AI capabilities. Now, solo developers and new users can experiment with cutting-edge multimodal AI, powerful reasoning, and web search (with GPT-5 mini) without needing a paid subscription.

Get started now

Ready to build with the latest from OpenAI? Follow these simple steps to integrate the GPT-5 series into your Giselle workflows:

  1. Log in — Use GitHub, Google, or email to access your Giselle workspace.
  2. Choose a plan — GPT-5 mini and GPT-5 nano are available on the Free Plan. For the full power of GPT-5, upgrade to a Pro Plan.
  3. Add a node — Drag a Generator Node onto your studio canvas.
  4. Select a model — In the Generator Node's Model tab, select gpt-5, gpt-5-mini, or gpt-5-nano from the OpenAI provider list.
  5. Connect input sources — Link documents, images, or codes to the node using File Nodes or GitHub Vector Store Nodes.
  6. Write a prompt & run — Configure your prompt with clear instructions and enable Search grounding if using gpt-5 or gpt-5-mini. Run your workflow to see the next-generation results!
