Release History & Changelog
Ghosty V5.2
Flagship ProductionAugust 24, 2026Our most comprehensive academic rewrite, combining a validated natural-text preprocessing stage with the protected fine-tuned rewrite.
- Natural-text Phase 1 with exact-atom and 85%-115% length validation
- Generic atomic ZXQ protection applied once before Phase 2
- Request-level Humanize and Rehumanize history with sanitized process metrics
Ghosty Lite V4.9
Direct High-ThroughputAugust 24, 2026High-velocity academic humanizer engineered for rapid iterative drafting, concise abstracts, and fast paragraph transformations.
- High-speed generation throughput with 2.5x faster velocity
- Optimized for quick drafting, concise abstracts, and methodology sections
- Strict deterministic formatting and citation preservation
Ghosty V5.1
Major ReleaseAugust 17, 2026Advanced cross-sentence semantic restructuring and natural cadence variation with zero-hallucination citation locking.
- Erased Claude underlying watermarks and stylistic fingerprints
- Advanced cross-sentence semantic restructuring and natural cadence variation
- Dynamic lexical entropy calibration preserving formal academic tone
Ghosty V5.0
Major ReleaseAugust 1, 2026Introduced document-level contextual synthesis, enabling the model to analyze the full narrative flow of a manuscript rather than isolated fragments.
- Full document-level contextual awareness eliminating boundary artifacts
- Up to 88.4% human-score reliability on Originality.ai Standard
- Enhanced passive-to-active voice modulation according to IMRAD conventions
- Substantially lowered over-editing on already-humanized introductory sentences
Ghosty V4.8
Citation & Fact FidelityJuly 1, 2026Focused on semantic drift minimization, citation formatting integrity, and scholarly precision in literature reviews.
- Reduced semantic drift by 14% on empirical claim assertions
- Comprehensive parser support for Chicago (Author-Date & Notes-Bib) and IEEE citation styles
- Preservation of numerical findings, p-values, and statistical confidence intervals
Ghosty V4.6
Burstiness TuningJune 1, 2026Calibrated sentence-length entropy (burstiness) specifically for APA 7th edition research designs and methodology sections.
- Perplexity smoothing on formal academic methodologies and empirical protocols
- Mitigated repetitive transition clichés ('Furthermore', 'Moreover', 'In conclusion')
- Enhanced vocabulary density calibration for peer-reviewed journal criteria
Ghosty V4.5
Foundational RolloutMay 15, 2026The initial architecture release establishing the proprietary Ghosty academic transformation paradigm.
- Dynamic burstiness balancing across IMRAD manuscript structures
- Unified perplexity smoothing eliminating robotic machine rhythms
- Foundational support for APA and MLA in-text citation masking
