Named after Hyperion (Ὑπερίων), Titan of light and heavenly observation — he who watches from above. Father of Helios, Selene, and Eos: the sun, moon, and dawn. The one who makes visible what was previously unseen. Research is exactly that: methodical illumination of unfamiliar territory.
How it works
Ask one research question. Hyperion sends it to three models in parallel, each with a different analytical lens. It extracts every citation those models produce, verifies them against five bibliographic layers, and has Anthropic Opus synthesize the perspectives into a single grounded report. If the output doesn't meet citation or coverage thresholds, the quality gate sends it back for another round.
MCP tools
deep_research(query, depth?, focus_areas?)— full academic pipeline: parallel dispatch, citation verification, Opus synthesis, quality gate.web_research(query, depth?, focus_areas?)— web-only pipeline (o3 + Sonar) for government, policy, news. Verifies URLs instead of academic citations.refine_research(original_query, gaps, previous_findings)— targeted follow-up when the quality gate flags gaps. Re-researches specific topics and merges with the original findings.verify_citations(citations)— standalone 4-layer citation check. Returns verified / suspicious / hallucinated classifications.format_paper(markdown, ...)— convert a markdown research paper into a formatted academic PDF (simple / IEEE / APA templates).
Models and perspectives
| Model | Perspective | What it does |
|---|---|---|
o3-deep-research | Innovator | Autonomous multi-step web research. Finds emerging trends, novel angles, what's overlooked. |
MiMo-V2-Pro | Methodologist | Evaluates evidence quality, rigor, systematic reviews. Identifies strongest evidence chains. |
Sonar Reasoning Pro | Contrarian | Seeks counter-evidence, critiques, minority expert opinion via Perplexity search. |
Anthropic Opus | Synthesizer | Merges all perspectives into a balanced report with verified citations. |
Citation verification
Every citation produced by the research models runs through a five-layer pipeline before it's allowed in the final report:
| Layer | Source | What it checks |
|---|---|---|
| 1 | arXiv API | Direct ID lookup for papers with arXiv IDs. |
| 2 | CrossRef / DataCite | DOI resolution or bibliographic title search. |
| 3 | OpenAlex | Title-based search with fuzzy matching. |
| 4 | Semantic Scholar | Cross-check against the S2 corpus. |
| 5 | Unpaywall | OA-link enrichment; can promote suspicious → verified. |
Classification is title-similarity against the resolved source: Verified (≥ 0.80, safe to cite), Suspicious (0.50–0.79, included with a caveat), Hallucinated (< 0.50, stripped from the final report).
Orchestrated with
Hyperion runs inside a LibreChat agent that has access to several companion MCPs. The agent calls them alongside Hyperion's own tools as the research demands:
- Scite.AI — 250M+ indexed articles with Smart Citations (supporting / contrasting / mentioning). Used to check whether a finding is trusted by the field or has been contested by later work.
- AlphaXiv — reads full papers, answers questions against their content, and does semantic similarity search. Goes beyond metadata to verify claims against the actual text.
- Tavily — fast web search and content extraction for spot-checks (~180ms, ~$0.001 per search). Used when the full
web_researchpipeline would be overkill. - Zotero (
zr-mcp-zotero) — persistent research library. Checks existing papers before external research, and saves verified citations into named collections afterward.

Best workflow for a literature review: mnemo to index the corpus you have → hyperion to discover what you don't → atlas to visualize the landscape → aletheia to verify the prose you write about it.
