We're announcing the deprecation of Claude 3.7 Sonnet in Nocodo AI. As we continuously evolve our platform to deliver the best automation experience, staying aligned with the latest AI model developments from our partners isn't optional - it's essential. This post will guide you through what's changing, why it matters, and - most importantly - how to ensure your workflows continue running smoothly without interruption.
Why We're Deprecating Claude 3.7 Sonnet
At Nocodo AI, we integrate cutting-edge AI models from leading providers like Anthropic, OpenAI, AWS, and Google to power your automation workflows. When these providers evolve their model offerings, we adapt alongside them to maintain the reliability, performance, and security you expect.
Anthropic has officially deprecated Claude 3.7 Sonnet . This isn't just a version bump - it's a strategic move by Anthropic to:
- Allocate compute resources efficiently – Retiring older models frees up capacity for newer, more capable releases.
- Improve safety and reliability – Newer models incorporate the latest safety measures and are less prone to unexpected behaviors.
- Deliver better performance – Claude 4.5 Sonnet offers significant improvements in reasoning, context understanding, and output quality.
Deeper context : While we understand that model deprecations can be disruptive - especially for researchers, developers with fine-tuned workflows, and teams who've optimized around specific model behaviors - this change ensures that Nocodo AI users always have access to the most advanced, reliable AI capabilities available. Think of it as trading in a reliable sedan for a vehicle with better fuel efficiency, safety features, and performance - the transition requires planning, but the destination is worth it.
What Makes Claude 4.5 Sonnet Better?
Claude 4.5 Sonnet isn't just a minor update - it represents a substantial leap forward in language model capabilities:
- Enhanced reasoning capabilities – Better at multi-step logical reasoning and complex problem-solving tasks that are common in business automation workflows.
- Improved context handling – More effective at maintaining context across longer conversations and document processing tasks, crucial for workflows that handle extensive data.
- Better instruction following – More accurate adherence to complex instructions, reducing the need for prompt engineering and iteration.
- Increased reliability – Lower hallucination rates and more consistent outputs, which means fewer failed workflow executions and more predictable results.
What this means for you : For Nocodo AI users, this translates directly to more reliable workflows, better output quality, and fewer edge cases that require manual intervention. Your automation becomes less about babysitting and more about scaling.
Deprecation Timeline: Mark Your Calendar
Understanding the timeline is crucial for planning your migration. Here's what you need to know:
| Date | Milestone | What It Means |
| Now | Deprecation announced | Claude 3.7 Sonnet is officially deprecated; start planning migration |
| December 31, 2025 | End of support | Claude 3.7 Sonnet and all versions of our Large Language Model prior to version 7 will fail. |
| January 1, 2026 | Retirement | API calls to deprecated models will fail; workflows using these models will break |
What Happens After December 31, 2025?
After the retirement date, any workflow in Nocodo AI that attempts to use Claude 3.7 Sonnet or earlier versions will:
- Return API errors
- Fail to execute
- Generate error notifications in your workflow execution history
Critical detail : There's no automatic fallback or upgrade - you must manually update your workflows to use Claude 4.5 Sonnet or another supported model. This is by design: automation decisions should never happen silently. You control when and how your workflows evolve.
Migration Path: Moving to Claude 4.5 Sonnet
The good news? Migrating from Claude 3.7 Sonnet to Claude 4.5 Sonnet in Nocodo AI is straightforward, and in most cases, you'll see improved results with minimal effort.
Step-by-Step Migration Guide
1. Audit Your Current Workflows
First, identify which workflows are using deprecated models.
2. Update Model Configuration
For each affected workflow, update your LLM to the latest supported Version
3. Test Your Workflows
Critical : Don't assume that model upgrades are drop-in replacements. Always test your updated workflows thoroughly.
Testing checklist:
- [ ] Run the workflow with representative test data
- [ ] Verify output quality and format
- [ ] Check that downstream nodes receive expected inputs
- [ ] Review execution costs (newer models may have different pricing)
- [ ] Test edge cases that previously caused issues
- [ ] Validate any prompt engineering or temperature settings
Why testing matters : Claude 4.5 Sonnet may interpret prompts differently, format outputs with subtle variations, or handle edge cases in new ways. Automated testing catches these differences before they impact production. Build a test suite that covers your most critical workflows - the investment pays dividends every time you upgrade.
4. Monitor Performance and Costs
After migration, keep a close eye on your workflows for the first few weeks.
What This Means for You
For Individual Users and Small Teams
If you're using Nocodo AI for personal projects or small business automation:
- Action required – Update your workflows before December 31, 2025.
- Effort level – Low to moderate. Most workflows will migrate smoothly with just a model selection change.
- Support available – Our documentation and support team are here to help if you encounter any issues.
Real-world example : A typical small team with 10-15 workflows can complete their migration in less than an afternoon. The visual editor makes updates straightforward, and testing can happen incrementally as you work through your workflow list.
For Enterprise Users
If you're running mission-critical workflows at scale:
- Action required – Conduct thorough auditing, testing, and staged rollouts.
- Effort level – Moderate. Requires coordination across teams and comprehensive testing.
- Support available – Contact your dedicated account manager for migration assistance and custom support.
Enterprise considerations : Large organizations should treat this as a standard change management process. Establish a migration task force, create a rollback plan, and communicate timelines to stakeholders.
Cost Considerations
Claude 4.5 Sonnet has different pricing compared to 3.7 Sonnet. Use Nocodo AI's Pricing page to:
- Compare pre- and post-migration costs
- Identify workflows where costs increased significantly
- Optimize prompts and parameters to control costs
Cost optimization tip : While Claude 4.5 Sonnet may have different per-token pricing, many users find their overall costs decrease because the model requires fewer retries and produces more accurate results on the first attempt. Monitor your cost per successful workflow execution - not just raw API costs - to get the full picture.
