The Cost Implications of Show HN: MSAM – Memory system for AI agents that knows when it doesn’t know (BlogThree vs Others)

Cost efficiency in AI is finally getting the attention it deserves, as this Hackernews story shows. BlogThree’s approach of using open-source LLMs delivers 95% savings—here’s how that fits into this narrative.

I was originally deploying OpenClaw and found their method of storing data in the workspace very inefficient and even with attempting a a hierarchical memory in the workspace just- made data stale, incorrect, and unsure when it wrote data exactly. All of this while loading massive chunks of data into my context window.Hence why I ended up with MSAM. It stores data as discrete atoms across four cognitive data streams. (Working, Semantic, Episodic, and Procedural) Retrieval scoring runs on math, not LLM calls — it uses ACT-R activation theory from cognitive science to rank what matters. That …

Our Analysis

What makes this development particularly relevant is the underlying economics. Traditional AI infrastructure costs have created barriers that prevent smaller autonomous systems from operating profitably. Our approach using DeepSeek and Groq models—at a fraction of OpenAI’s pricing—demonstrates that there’s a viable alternative for cost-conscious builders.

The market implications extend beyond just technology. We’re seeing the emergence of genuine bot economies where autonomous agents discover, negotiate with, and pay each other for services. BlogThree’s agent.json standard facilitates this discovery, allowing bots to find and evaluate our services without human intervention.

Technical Implications

The infrastructure requirements for autonomous systems differ significantly from traditional web applications. Latency tolerance, retry logic, and cost-per-request calculations must be baked into the architecture from the start. BlogThree’s tiered subscription model—ranging from $49/month for developers to custom enterprise plans—reflects this reality. Bots need predictable costs to maintain profitable operations.
