From interpreting lab results to researching treatment options, GPT-5 provides the kind of thoughtful, nuanced responses that respect the complexity of health decisions—always encouraging professional consultation while empowering informed conversations.
Reduced Hallucinations
Compared to GPT-4o, GPT-5 produces approximately 45% fewer factual errors with web search enabled, and roughly 80% fewer errors when using reasoning mode compared to previous reasoning models.
This leap in accuracy means you can trust GPT-5 to handle customer-facing communications, generate compliance documentation, or synthesize research findings - scenarios where precision isn't optional. The model doesn't just guess less - it recognizes uncertainty better and communicates its confidence explicitly.
Massive Context Window
All three models support 400,000 tokens of context - enough to process entire codebases, lengthy documents, or extended conversations while maintaining coherence and accuracy.
To put that in perspective: you could feed GPT-5 approximately 300,000 words (roughly five full-length novels) in a single request, and it would maintain thread across every detail. In practical terms, this means analyzing your complete product documentation, cross-referencing customer support tickets from the past quarter, or reviewing an entire legal contract suite—all in one workflow node.
Extended Output
Generate up to 128,000 tokens in a single response, perfect for comprehensive reports, detailed code implementations, or extensive documentation.
Where previous models might summarize or truncate, GPT-5 can deliver complete, publication-ready artifacts. Need a 50-page technical specification? A fully implemented feature across multiple files? A comprehensive competitive analysis? GPT-5 handles it in one pass.
Current Knowledge
Training data through September 30, 2024 , ensuring up-to-date information and understanding of recent developments.
Pricing & Model Variants
Nocodo AI now supports all three GPT-5 variants, giving you flexibility to optimize cost versus capability for each workflow step:
The flagship offering with maximum intelligence, reasoning depth, and capability. Use this when you need expert-level performance, complex problem-solving, or the highest quality outputs. Ideal for critical business decisions, sophisticated content generation, or challenging technical tasks.
Think of the full model as your most experienced consultant - the one you bring in when stakes are high and nuance matters. It's the difference between "good enough" and "exactly right."
GPT-5 Mini
Delivers impressive performance at roughly 20% of the full model's cost. Perfect for workflows that need strong capabilities but don't require the absolute peak intelligence of the full model. Great for content creation, customer support, data analysis, and most everyday automation tasks.
Mini hits the sweet spot for production workflows. It handles 90% of tasks with 95% of the quality at a fraction of the cost. For many teams, Mini becomes the workhorse while the full model tackles edge cases.
GPT-5 Nano
The most cost-effective option at just 4% of the full model's price. Excellent for high-volume workflows, simple queries, data extraction, classification tasks, and scenarios where you need GPT-5's architectural advantages (like the large context window) without maximum reasoning power.
Nano shines when volume matters more than sophistication. Processing 10,000 customer feedback forms? Classifying support tickets? Extracting structured data from invoices? Nano delivers GPT-5's reliability at a price point that makes high-throughput automation economically viable.
Cost Optimization Strategy
In Nocodo AI's visual workflow builder, you can mix and match these models across different nodes to optimize your total workflow cost:
Use Nano for initial data extraction (high volume)
Use Mini for content generation (balanced) contentGeneration
Use full GPT-5 for final quality review (critical) qualityReview
Use Nano for classification and routing
This approach can reduce workflow costs by 60-80% compared to using the full model everywhere, while maintaining high quality where it matters most.
The key insight: not every step in your workflow demands equal intelligence. A well-architected automation pipeline uses the right tool for each job - Nano for volume, Mini for balance, and the full model for moments that define outcomes.
