Keywords

For voice calls we're introducing keywords. This allows your agent to understand hard to pronounce proper nouns (like product and company names), industry jargon, phrases and more. This is an optional field.

Multilingual

We're exposing Deepgram's latest Nova-3 multilingual model as an STT option, capable of understanding and transcribing 8 different langauges.

In addition, the standard English STT is being updated from Nova-2 to Nova-3, for a boost in performance.

Today marks a significant milestone in Voiceflow's journey as we officially launch our new credit-based billing system. This update represents a fundamental shift in how you'll track, manage, and optimize your Voiceflow usage—all designed to bring greater simplicity, transparency, and predictability to your experience.

What's New

🎉 Voiceflow Credits

We've completely overhauled our billing system, moving away from the complex token-based approach to a streamlined credit system that unifies tracking across all platform features:

• Simplified Measurement: One unified credit system for all actions (calls, messages, LLM responses, TTS)
• Predictable Costs: Clear pricing tiers that make budget planning straightforward
• Transparent Usage: Detailed visibility into exactly how your credits are being consumed
• Developer-Friendly: Messages only count toward credits when your agent is used in production—not when developing in-app or using shareable prototypes

📊 New Usage Dashboard

We've launched a brand-new Usage Dashboard that gives you comprehensive insights into your credit consumption. The dashboard allows you to:

• View your total available and used credits
• Track usage across all agents or drill down into specific ones
• Monitor editor and agent allocation
• Analyze usage patterns over time

💼 Enhanced Team Management

Additional editor seats are now just $50 per month with no complicated caps or restrictions. Add as many team members as needed, whenever you need them.

🏢 Business Plans (formerly Teams)

As part of this update, we're renaming our Teams plans to Business plans, with enhanced features and capabilities for enterprise customers.

Resources to Help You Transition

We've created dedicated resources to help you understand and make the most of the new credit system:

• What are Voiceflow Credits? - A comprehensive guide to understanding how credits work
• Introducing Voiceflow Credits - Learn about the philosophy behind the change and how it benefits you
• Credit Calculator - Estimate your credit needs based on your specific usage patterns

Frequently Asked Questions

What do I need to do?
Use our Credit Calculator to understand your usage. For most users, no action is required.

Will my monthly bill increase?
Most organizations will see a decrease in costs, particularly those with multiple editor seats. There are three changes to be aware of:

• Annual plans now offer a 10% discount (previously 20%)
• Editor seats now cost $50/month with no restrictions (a price reduction)
• Business plan (formerly Teams) base tier increases from $125 to $150

Do credits roll over?
Credits expire at the end of your subscription period. For monthly plans, unused credits don't roll over month-to-month. Annual subscribers receive all credits at once to use throughout the year.

What happens if I exceed my credit allocation?
You'll receive a notification as you approach your limit. There's no automatic charging—you can choose whether to upgrade to a higher credit package.

Do messages in development count toward my credit usage?
No, messages only count toward credits when your agent is used in production. Messages sent while developing in-app or when using shareable prototypes don't consume credits, giving you the freedom to build and test without worrying about credit usage.

We're committed to making this transition as smooth as possible. If you have any questions or need assistance, please reach out to [email protected].

Conversation memory is a critical component of the Agent and Prompt steps. Having longer memory gives the LLM model more context about the conversation so far, and make better decisions based on previous dialogs.

However, larger memory adds latency and costs more input tokens, so there is a drawback.

Before, memory was always set to 10 turns. All new projects will now have a default of 25 turns in memory. This can now be adjusted this in the settings, up to 100 turns.
