Fine-Tuning
Customize Chronos DX with customer or prepared datasets for domain knowledge, terminology, behavior and structured outputs.
Chronos DX · AI Model Engineering
AI Model Training & LLM Fine-Tuning from 8B to 80B
Train, fine-tune, specialize, retrain and optimize Chronos DX large language models with managed LoRA/QLoRA workflows, dataset engineering, validation, dense model generation, GGUF export and production-ready artifacts.
Capabilities
From training data to production model
Chronos DX supports complete model customization and lifecycle services while the underlying implementation and optimization technology remain private.
Domain Specialization
Improve focused model capabilities for professional and technical domains including coding, engineering, cybersecurity, IT operations, AI/ML, finance, medical and healthcare knowledge, biology and life sciences, chemistry, scientific reasoning, languages, enterprise knowledge and technical support. Custom specialization is also available for organization-specific knowledge, workflows, terminology and professional requirements.
Retraining & Updates
Update existing Chronos models using new examples, corrected knowledge, new standards or additional customer data.
Dataset Engineering
Cleaning, normalization, formatting, quality filtering, train/validation splits and synthetic training-data generation.
Model Repair
Identify recurring weaknesses, train corrective updates and validate the result against the previous model.
Progressive Capability Expansion
Add and validate new capabilities over time without treating every model update as a completely new project.
Benchmark & Regression Validation
Compare target-task gains and general-quality retention before a candidate model is approved for delivery.
Model Consolidation
Prepare consolidated artifacts after training with optional calibration, validation and recovery passes.
Dense Model Artifacts
Create dense model outputs for storage and delivery. Artifact generation is independent from hosted inference.
GGUF & Quantization
Prepare supported Q8, Q6, Q5, Q4 and GGUF variants for compatible production and local runtimes.
Versioning & Checkpoints
Maintain model generations, recovery points and rollback options across longer training and update cycles.
Private Managed Workflow
Requests are reviewed before execution. Internal training, optimization and infrastructure details remain proprietary to Flushnet.

Questions
Chronos DX training and fine-tuning FAQ
What model sizes can Flushnet train or fine-tune?
Chronos DX training services currently cover model classes from 8B through 80B parameters, including 8B, 12B, 20B, 32B, 40B, 70B and 80B.
Do you support LoRA and QLoRA fine-tuning?
Yes. Chronos DX supports LoRA and QLoRA fine-tuning as well as broader supervised and targeted model-training workflows where appropriate.
Can you fine-tune or update an 80B model?
Yes. Chronos DX services include 80B fine-tuning, specialization and targeted dense-model training or updates. Hosted 80B inference is a separate service.
Can you create a custom training dataset?
Yes. Flushnet can prepare customer data or generate synthetic training datasets, then clean, filter, structure and validate them before training.
Can you deliver GGUF or quantized models?
Yes. Production services include GGUF export and supported Q8, Q6, Q5 and Q4 quantization options, depending on the requested target artifact.
Can an existing Chronos model be retrained instead of rebuilt?
Yes. Existing models can be updated, repaired or specialized using new datasets and validation criteria without automatically requiring a complete rebuild.
