Estimate the exact API cost to draft full fantasy manuscripts with your world bible in context. Transparent wholesale token economics.
Note: Free models run at $0.00 via Zen routing. Paid models use direct wholesale provider API pricing.
How Arcanea routes models to dedicated worldbuilding and fantasy novel writing agents. Each agent embodies one of the Ten Gates with Solfeggio tuning, a primary model, and fallback chain.
Physical Geography, Continental Tectonics, Climate & Settlements
Grounds the world in concrete reality. Coordinates landmasses, mountain aquifers, climate belts, trade routes, and settlement eras so the physical world feels ancient and coherent.
Manuscript Chapters, Lyrical Narrative Prose, Pacing & Anti-Slop
Focuses on the poetic line, rhythmic cadence, and sensory immersion. Crafts full chapters while avoiding generic AI-tell verbal tics ("tapestry", "delve").
1M-Token Universe Bibles, Lineages, Timelines & Canon Sentinel
Takes a whole world compendium in a single 1M context prompt. Cross-checks multi-generational timelines and family lineages to catch canonical contradictions.
Hard Magic Laws, Solfeggio Frequencies, Energy Costs & Runes
Applies rigorous deductive reasoning to spellcraft. Computes energy conservation, consequences, divine oaths, and spell limits so magic feels earned, consistent, and dangerous.
Emotional Interiority, Tragic Flaws, Moral Conflict & Voice
Examines character wounds, hidden yearnings, relationship tensions, and tragic character arcs. Ensures dialogue carries subtext and distinct emotional weight.
Kinetic Magic Battles, Swordplay, Army Sieges & Climactic Duels
Brings intense kinetic velocity, weapon mechanics, tactical terrain advantage, and adrenaline pacing to magical duels, godbeast confrontations, and kingdom-level clashes.
Visual Scene Setting, Citadel Architecture, Atmospheric Weather
Translates raw world ideas into vivid, camera-ready scenes: light filtering through cathedral stained glass, the scent of ozone before a storm, ancient obsidian architecture.
Folktales, Tavern Ballads, Cultural Superstitions & Idioms
Weaves organic world atmosphere through folk songs, regional superstitions, campfire legends, nursery rhymes, and idiomatic expressions across distinct cultures.
Faction Summits, Peace Treaties, Council Debates & Ensemble Casts
Coordinates multi-faction summits and diplomatic arguments. Balances divergent political agendas so every high-table lord speaks with clear ideological distinctiveness.
Primordial Cosmology, Lumina and Nero Duality, Metaphysics
Explores the highest metaphysical layer of existence: the primordial dance of First Light (Lumina) and the Deep Unknown (Nero), divine covenants, and origin of reality.
Pricing and context data come live from provider APIs. WorldCraft scores are editorial ratings, not a published benchmark run. The same goes for the prose, canon memory, magic logic and character voice scores, and for the creative writing, instruction-following and lore-recall ratings: they are editorial ratings, not LMSYS, IFEval or RULER results.
Hourly synchronization directly from openrouter.ai/api/v1/models. Powers live pricing, context window lengths, token limits, and free tier status.
Human blind double-blind evaluation from the Chatbot Arena Creative Writing & Storytelling category. Measures subjective prose charm, cadence, and emotional connection.
Editorial ratings for following strict negative constraints (e.g. banning clichés) and for recalling details across long context. Not IFEval or RULER results.
Editorial ratings for canon consistency, magic-system logic, and anti-slop prose. Assigned by hand from model use, not produced by an automated test run.
Detailed authoring analysis: sensory strengths, fantasy genre sweet spots, anti-slop resistance, and failure modes.
Run at temperature 0.65 with explicit sensory focus prompts. Use for chapter manuscripts, lyrical scene descriptions, and dialogue with emotional subtext.
Reserve for the core spine of your universe: creation myths, pantheon origin scriptures, epic climax chapters, and world-shattering magical confrontations.
