Frequently Asked Questions

Find answers to common questions about OPAL Chat Service plans

Can I upgrade or downgrade my plan anytime?
Yes! You can upgrade or downgrade your plan at any time. When you upgrade, you'll have immediate access to the higher tier's features. When you downgrade, the change takes effect at your next billing cycle.
What is "Bring Your Own Key" (BYOK)?
BYOK allows you to use your own API keys for LLM services (like OpenAI). This keeps your keys secure and gives you more control over billing and usage. The Max tier also supports system-wide API keys for enterprise deployments.
What are tokens and how do they affect my usage?
Tokens represent the size of text being processed. Each plan has limits on: tokens per prompt (input), tokens per session (total), and prompts per session (number of interactions). These ensure fair resource allocation and prevent unexpected charges.
Is there a free tier available?
Yes! Our Entry Level tier is completely free. It includes basic features with conservative limits to help you explore OPAL's capabilities. Upgrade anytime as your needs grow.
What happens if I exceed my plan limits?
When you approach your limits, you'll receive notifications. If you exceed them within a session, that session will be paused until the limit resets. We recommend upgrading to a higher tier if you consistently hit limits.
Do you offer discounts for annual billing or enterprise use?
Yes! We offer special pricing for annual subscriptions and custom solutions for enterprise clients. Contact our sales team for details on bulk licensing and enterprise agreements.
Which tier should I choose for my use case?
Start with Entry Level to explore features. Choose Plus for regular production use with moderate complexity. Pro is ideal for advanced analytics and multiple specialized agents. Max is designed for enterprise deployments with unlimited access and dedicated support.
