Caspian Buildathon: Build agents that can reach anyone

Overview

Caspian Buildathon is an online 15 day AI agent hackathon organized around Caspian’s platform. The focus is to build an AI agent that can operate across multiple communication channels using a single handler. Participants are encouraged to create agents that can think and act across email, Slack, Discord, Telegram, WhatsApp, and other channels, effectively giving a single agent reach into human communication workflows. In this challenge, the emphasis is on practicality and creativity, with a preference for implementations that actually run rather than simulated demos.

Format

Fully online over a 15 day window. The brief describes one rule for qualification: the agent must use caspian-sdk and run on at least two supported channels. Submissions require a public GitHub repository and a demo video. Featherless.ai serves as the inference partner, with an incentive of a $25 Featherless.ai inference plan for each participant to enable low friction experimentation during the hackathon.

The Brief

Build any AI agent you want. Any domain, any problem. The challenge does not prescribe a specific use case, but it requires the agent to operate across multiple channels through a single handler using the caspian-sdk. The brief emphasizes practicality: the agent should read email and notify you via Telegram or other channels when relevant events occur, and it should be possible to follow up with customers across the channels managed by the handler. It also outlines acceptance criteria and guidance on starting points.

Submission Details

• Public GitHub repository
• Demo video
• Inference partner: Featherless.ai (inference plan provided)
• The agent must run on at least two channels through a single handler; duplicating per-channel handlers does not count
• Judging criteria emphasize creativity and real functionality over polish; a rough yet functioning agent can win over a perfectly polished but nonfunctional demo
• Eligibility is broad but with some limits on age and team composition; a single submission per team is allowed

Getting Started

Caspian is fully open source. The repository for the Caspian SDK is hosted at GitHub, and official documentation is available at TryCaspian.ai. Discord is listed as a primary community channel for collaboration and support. Participants can access starter credits for paid channels during the event, and there is guidance on how to get started quickly with the Caspian SDK and its multi-channel capabilities.

Prizes and Schedule

The page notes prizes totaling approximately $1,900 in cash, plus Caspian credits and Featherless.ai credits for winners. It also mentions a live judging process where finalists may be invited to demo live. The event includes a detailed set of rules and a Getting Started section with links to repositories, documentation, and community resources. A schedule and calendar options are provided for Apple, Google, and Outlook calendar integrations so teams can align deadlines with their workflows.

Who should attend

Open to students and others who can work in small teams (1 to 2 people). No prior Caspian experience is required, and the challenge explicitly supports solo entries as well. The ground rules encourage experimentation, collaboration, and rapid iteration within the 15-day window.

FAQ and Support

Resources include a Help desk and a community Discord for ongoing support. The page highlights the open nature of the Caspian project, the public repository, and the public nature of submissions. In short, this is a hands-on, creative, and collaborative hackathon focused on building multi-channel AI agents that can operate in real world contexts.
