Vision

Vendor & model agnostic, performance first. Access Yggdrasil via REST API, MCP gateway, CLI, or web UI, no lock-in, full customization, and full control of your data.

Multi interface

  • API: headless integration
  • MCP: plug any MCP, tool orchestration
  • CLI: scripts & profiles
  • Chainlit UI: chat

Use the interface that fits your workflow.

Vendor agnostic

Multiple LLM backends: OpenRouter + direct APIs.

Switch providers without rewriting your workflow.

Model agnostic

Realm-specific SOTA: DeepSeek R1, Qwen Coder, Perplexity Sonar, Gemini, Claude Opus, GPT, and more.

  • Mix and match
  • No single model dictates your stack

Performance focused

  • Valkyrie early exit + parallel scouts
  • Smart context truncation: lower cost & latency
  • Real-time cost tracking

Full customization

Modes: Loki, Odin, Eir, Tyr, Kvasir, Sindri

  • Memory profiles & personas
  • Tune behaviour, budgets, tool sets

Full data control & download

Your data stays yours.

  • Export & download: conversations, memory, sessions
  • Privacy modes
  • Local / self-hosted where available

Features

Four stag perspectives run simultaneously inside every realm. Valkyrie monitors each scout in real-time and triggers early exit on breakthroughs, delivering up to 2.2× speedup on GAIA-class queries.

The Four Stags (Per-Realm Parallel Perspectives)

❇
Dáinn, The Chronicler
Gathers evidence and prior knowledge. Best for research and building on established work.
✴
Dvalinn, The Weaver
Threads ideas into unified narratives. Best for synthesis and finding coherence across sources.
☸
Duneyrr, The Challenger
Questions assumptions and probes contradictions. Best for critical analysis and stress-testing.
✵
Durathor, The Pathfinder
Explores unexpected solution spaces. Best for creative breakthroughs and novel angles.

𓆩✧𓆪 Valkyrie Protocol

Monitors every parallel scout in real-time. When a scout emits a high-confidence signal (ANSWER[0.92]), Valkyrie cancels remaining scouts and routes directly to Ragnarök synthesis.

Confidence Gate
CONVERGE
Answer ≥ 85% confidence → cancel remaining scouts, route to synthesis immediately.
DEEPEN
One path 30%+ more promising → focus resources on the winning direction.
PROPAGATE
Useful constraint found → broadcast to all active scouts to prevent duplicated work.
CONTINUE
No breakthrough detected → all scouts keep running until completion.

Efficiency · Shared knowledge · Learning from mistakes

❟❛❟

Save & rewind

Save your progress. If something goes wrong, rewind and try again, no starting from scratch.

◆ Saves at important steps
◆ Rewinds when something fails or times out
◆ Tries again with a different approach
◆ No redoing everything from the start
𔓂

Shared memory

One search, everyone benefits. No repeated lookups or duplicate work.

◆ Findings are shared across all reasoning paths
◆ No duplicate web searches or tool runs
◆ Smart recall: similar questions reuse answers
◆ Fresh each session: resets after 24 hours
ᚺ

Learn from mistakes

Remembers what went wrong. Doesn't repeat the same mistakes.

◆ Remembers why something failed
◆ Across conversations: lessons stick around
◆ Learns from every dead end

Usage & Integrations

Three ways to run Yggdrasil, interactive web UI, command-line with memory profiles, or headless REST API. All share the same core reasoning engine.

🌐

Chainlit Web UI

The primary interface. Chat with streaming, visual realm navigation, creature insights, real-time cost tracking (USD), and voice input via microphone.

# Docker (recommended)
docker compose up yggdrasilagent-ui
# Local
chainlit run apps/app_chainlit.py
# Then open:
http://localhost:8000
◆ Streaming chat with realm progress
◆ Google OAuth (production) or local auth
◆ Typo-tolerant quick commands
◆ Real-time cost summary per session
⌨

CLI Interface

Full-featured command-line agent with memory profiles, session management, persona switching, privacy modes, and budget-constrained queries.

# Web search + memory profile
yggdrasil --web-search --profile work \
"Analyze AI agent market 2026"
# Privacy mode (no persistence)
yggdrasil --private "Sensitive query"
# Odin persona, 8 iterations
yggdrasil --persona odin --max-iterations 8
◆ Profiles: work, research, custom
◆ Privacy modes: normal / private / fresh
◆ Session resume & export
◆ 7 persona modes (Loki, Odin, Eir, Tyr…)
⚡

REST API (FastAPI)

Headless access via Google OAuth2 + JWT. Full Swagger UI at /docs. Designed for integration into your own applications and workflows.

POST /api/v1/reason
{
"query": "Analyze EV market 2026",
"max_iterations": 5,
"enable_web_search": true,
"profile": "business"
}
# → final_answer, cost, citations
◆ Google OAuth2 + JWT auth
◆ Session management endpoints
◆ /docs
