Building an AI News Agent
with HPC-AI Model APIs

~$0.69 full overnight run cost
Quick setup

Author: Shane from LLM Implementation

Shane from LLM Implementation built an autonomous AI news agent powered by HPC AI Model APIs.

The system runs overnight, continuously collects news, removes duplicates, and generates a structured daily briefing, fully automated with minimal human input.

What the System Does

The AI agent:

  • Collects news every 30 minutes
  • Filters duplicates automatically
  • Stores and aggregates articles overnight
  • Selects the top 5 most relevant stories
  • Sends a daily summary via Telegram

By morning, users receive a complete AI-generated news brief.

Architecture

The system combines:

  • Agent runtime: Open-source AI agent framework
  • Sandbox environment: NVIDIA OpenShell for secure execution
  • Model layer: HPC AI Model APIs (OpenAI-compatible endpoints)
  • Tools: Web search API + Telegram bot integration

This modular setup allows the agent to act, reason, and communicate across tools.

Key Insight: Markdown-Driven Intelligence

Instead of hardcoding behavior, the agent is controlled through Markdown files that define:

  • Research rules
  • Memory and safety constraints
  • Scheduling logic (heartbeat system)
  • Query strategies

This makes the system highly flexible and easy to modify.

Automation Design

Two main processes run the system:

  • Heartbeat (every 30 min): collects and updates news
  • Daily cron job (8:00 AM): generates and sends final briefing

This separation ensures continuous data collection and structured output.

Results

Overnight execution showed:

  • 29 articles collected
  • Automatic deduplication
  • Continuous self-updating research loop
  • Final AI-generated 5-story briefing delivered via Telegram

The system also intelligently identified when no new research was needed.

Cost Efficiency

The full overnight run cost approximately: ~$0.69 total

Demonstrating that autonomous AI agents can operate at very low cost while handling continuous workloads.

Key Takeaways

  • Markdown-based agent design enables easy customization
  • Sandbox environments improve safety and control
  • Model APIs allow fast, OpenAI-compatible integration
  • Agents can now autonomously collect, filter, and summarize information

Conclusion

This build showcases how HPC AI Model APIs, with OpenAI-compatible endpoints, make it easy to power autonomous AI agents, from continuous data collection to structured insight generation. Developers can quickly integrate, experiment, and scale AI workflows without complex setup.
