How to get the most out of rasa
- Start with the highest-volume task. Pick the use case you'll do most often, and perfect that prompt first.
- Build a prompt library. Save your best prompts in a doc. Reuse across team members.
- Add context every time. "I'm a [role] doing [task] for [audience]" outperforms bare requests by 30-50%.
- Iterate, don't settle. The first response is rarely the best. Ask for 3 variations and pick.
- Combine with another tool. rasa + a search/voice/image tool usually beats either alone.
What rasa is not great at
- Real-time information (use a search tool for current data)
- Tasks requiring deep domain expertise you don't have
- High-stakes decisions without human verification
- Anything that needs the latest data from the web
Pricing reality check
Model APIs charge per million tokens. Cheaper open models (DeepSeek, Qwen) are 10-50x cheaper than GPT-4o.
