GPT5 Model Variants and Specifications
OpenAI has launched multiple versions of GPT5, each tailored for specific use cases:
- GPT5: The flagship model, designed for coding and agentic tasks across various domains. It is intended to be the best model for applications like RU code or any agentic coder.
- GPT5 Mini: A faster and more cost-efficient version of GPT5, optimized for well-defined tasks.
- GPT5 Nano: The smallest, fastest, and cheapest variant, ideal for summarization and classification tasks.
- GPT5 Chat: A chat-focused model, representing the GPT5 snapshot currently used in ChatGPT, trained for human preference.
- GPT5 Pro: The most advanced model, intended to replace models like 03 Pro, exclusively available on ChatGPT's pro plan.
All models share a 400k context window. GPT5 and GPT5 Mini support reasoning variants. A new "minimal reasoning" option is available across models. A "verbosity parameter" allows adjusting output length for cost optimization.
Pricing:
- GPT5: $1.25 for input, $10 for output.
- GPT5 Mini: $0.25 for input, $2 for output.
- GPT5 Nano: $0.05 for input, $0.40 for output.
Benchmarks and Performance
GPT5 achieves state-of-the-art (SOTA) scores on benchmarks like Swbench and Ader Polyglot. The presenter notes a potential issue with the visual representation of benchmark data, questioning the scaling of the chart.
Accessing and Using GPT5
The models are being rolled out via the API. Free access may be available through the GitHub models API. Kilo Code offers a platform to use the models with $20 of free credit.
Methods for using GPT5 as a coder:
- VS Code Co-pilot: Update VS Code and install the Co-pilot extension. GPT5 will soon be available with free Co-pilot limits.
- Klein: For paid access, select the OpenAI option in Klein settings, choose the new model, and input your API key.
- RU Code: Update RU Code, select the provider, and choose the new model.
- Open Router/Requesty: Alternative platforms for accessing the models.
- Kilo Code (Free): Install Kilo Code from the VS Code marketplace to access $20 of free credits and use GPT5, GPT5 Nano, and GPT5 Mini.
Dart: AI-Powered Project Management (Sponsored Segment)
Dart is presented as a project management tool enhanced with AI features.
Key features:
- AI-powered brainstorming, task list generation, and task completion.
- Custom AI agents triggered by integrations, N8N workflows, or custom webhooks. Examples include coding agents for GitHub pull requests, marketing agents for campaigns, and mailing agents for outreach.
- Integration with existing workflows via MCP server, connecting to Claude, ChatGPT, and other AI tools.
Most features are free, with premium options starting at $8 per month.
Initial Impressions and Future Testing
The presenter is currently testing the models and will release a detailed testing video soon. Initial impressions suggest "interesting stuff" and encourages viewers to share their experiences with the models.
Conclusion
OpenAI's GPT5 launch introduces a suite of models tailored for various tasks, from coding to chat. The models offer improved performance and cost-efficiency, with multiple access options, including free trials and API integrations.
