Agent Types
Megabyte Island offers three pre-configured agent templates. Each uses a different model and system prompt optimised for a specific use case.
WhatsApp Agent
Model: llama3-70b-instruct Best for: WhatsApp Business channels, SMS bots, mobile support.
The WhatsApp agent is tuned for brevity and readability on small screens. It avoids long paragraphs, uses plain language, and keeps responses under 3β4 sentences unless more detail is explicitly requested.
Typical use cases:
- Customer support for e-commerce stores
- Appointment reminders and booking confirmations
- FAQ bots for mobile audiences
Web Lead Agent
Model: mistral-7b-instruct Best for: Website chat widgets, landing page assistants, lead capture.
The Web Lead agent is question-driven. It asks qualifying questions to understand the visitorβs needs, then guides them toward a desired conversion action (booking a call, submitting a form, etc.). It is designed to capture name and email naturally during conversation.
Typical use cases:
- SaaS trial sign-up assistants
- Real-estate enquiry bots
- Agency lead qualification
Brain Agent
Model: llama3-70b-instruct Best for: Internal knowledge bases, research assistants, document Q&A.
The Brain agent is configured with a mandatory citation policy: every factual claim must reference a source document from the attached knowledge base. If no citation is available, the agent explicitly says so rather than hallucinating. This makes it suitable for compliance-sensitive environments.
Requirements:
- At least one knowledge base document ID is required at setup.
- Documents must be uploaded to the platform before provisioning.
Typical use cases:
- Internal HR policy bots
- Legal document assistants
- Technical documentation Q&A
