Introducing Nebula
Large Language Model for Human Conversations
We are excited to introduce Nebula, Symbl.ai’s proprietary LLM, for natural human conversations. Nebula enables businesses and developers to build Generative AI experiences and workflows that involve human conversations.
Key Highlights

Optimized For Conversations
Nebula is Symbl.ai’s proprietary LLM optimized specifically for processing natural human conversations. It is capable of processing various types of conversations such as sales, contact center, recruitment, meetings, emails, chats, and more.
Versatility
Nebula can perform instruction tasks such as request summaries, follow-up questions, draft emails, issues to review, qualify sales leads, identify and recommend resolutions to customer issues, or even recommend business opportunities. Nebula can also respond to questions about the conversation.
On-Prem Deployment
Nebula is also available for on-prem deployment for businesses with tight data security needs. By deploying on-prem, a company can manage sensitive information within its own infrastructure, ensuring data protection control towards safeguarding against unintended data access, data leaks or data breaches.
Nebula Generative LLM
Use the generative LLM to analyze conversation transcripts and generate follow up content such as emails, concise meeting summaries, and actionable next steps. Seamlessly ask contextual queries to explore discussions in greater detail. Receive pragmatic suggestions for enhancing the productivity, collaboration, and coherence of your conversations.
Get started with our intuitive no-code playground. Utilize sample dialogue transcripts and prompts, or inject your own inputs. Alternatively, use the Model API—a REST API that grants you programmatic access to Nebula to integrate it into your existing tech stack.
Nebula Embeddings
Use Nebula Embeddings to build advanced search across conversations, categorize meetings, perform analysis on historic conversations data based on similarities, and generate recommendations.. Generate vector embeddings using Nebula Embedding API for your conversations, emails, calls, and messages.
Use Cases
Nebula is a large language model (LLM) trained to understand nuances in human conversations and perform instructed tasks in the context of the conversation such as
Using Nebula In Your Applications
Nebula can analyze conversation transcripts and generate responses based on the conversation along with the instruction or question in the prompt. Furthermore, developers can provide Nebula with instructions such as request summaries, follow-up questions, draft emails, issues to review, qualify sales leads, identify and recommend resolutions to customer issues, or even recommend business opportunities. Nebula can also respond to specific questions about the conversation as part of the instruction.
Call for Developers
At Symbl.ai, we believe that there’s tremendous value in human conversations especially in businesses, and Nebula can help harness that value across various conversation types. We are excited to see what you build with Nebula. We have been working with developers and businesses who have been pushing boundaries by leveraging advanced generative AI for conversation intelligence and we’re eager to offer the power of Nebula to this inspired community. In the same spirit, we encourage you to apply for our Startup program if you are working at a startup or sign up to become a model tester and accelerate your access to the Nebula model. We’d love to see our current and future developers push the boundaries of conversation understanding with Nebula.
