LLM cost profile
Rule-based extraction and SHA256 caching eliminate most LLM calls.
| Event type | LLM cost | Reason |
|---|---|---|
| Structured JSON event | $0.00 | Rule-based extractor |
| Repeated free-text log | $0.00 | SHA256 cache hit |
| New free-text (first time) | ~$0.0003 / 1K tokens | Claude Haiku → cached forever |
| Why-query (DFS traversal) | $0.00 | Graph math, no LLM |
| Explanation synthesis | $0.00 | Template engine |
Typical 100-event session: ~$0.002 total. Subsequent runs: $0.00.
FAQ
- Do I need an Anthropic API key?
- Only for free-text log extraction. Structured JSON events and why-queries are zero LLM — no key needed for those. Set ANTHROPIC_API_KEY in your env and Engram calls Claude Haiku directly. You pay Anthropic (~$0.002 per 100-event session).
- Is there a usage limit on the free tier?
- No. It runs entirely on your machine. The only limits are your own compute and your Anthropic API quota.
- When will hosted tiers be available?
- We're working on it. Email hello@engram.viberank.co.in to get notified when Pro launches.
- What license is Engram?
- MIT. Use it in commercial projects, modify it, redistribute it.
