Experiment Control & Recovery

Protean AI is designed for iterative, fault-tolerant, and reproducible fine-tuning. Rather than treating training runs as disposable, Protean AI treats them as stateful experiments that can be cloned, resumed, extended, or branched safely.

This page documents the supported operations for continuing or evolving fine-tuning runs.

Clone Fine-Tune Configuration

Cloning a fine-tune configuration creates a new fine-tuning run using the same configuration as an existing one.

This operation copies:

• Model selection
• Training dataset and revision
• Hyperparameters
• Evaluation and snapshot settings

It does not copy:

• Training state
• Optimizer state
• Adapter weights

The new run always starts from the base model.

When to Use

Use Clone Configuration when:

• Running controlled experiments with slight parameter changes
• Testing alternative hyperparameter values
• Comparing datasets while keeping training logic identical
• Creating a clean baseline without inheriting previous learning

Result

• A new fine-tune run is created
• Training starts from scratch
• Results remain comparable due to shared configuration

See the screenshot below for an example of Clone Finetune Configuration.

Resume a Specific Failed Trial

Resuming a fine-tune run restores the training process from a previously saved snapshot. This allows training to continue without loss of progress. Protean AI supports multiple resume strategies depending on failure context and intent.

If a fine-tuning trial fails (e.g., due to node failure, OOM, transient error), a specific trial can be restarted.

This operation:

• Restores the trial from its last valid snapshot
• Uses the original configuration
• Preserves trial identity

When to Use

Use this when:

• Failure was infrastructure-related
• Configuration is known to be correct
• Training progress should be preserved

Result

• The same trial continues
• Metrics remain part of the same trial history
• No new trial is created

See the screenshot below for an example of Resume a Specific Failed Trial.

Add a New Trial After a Failed Trial

Instead of resuming a failed trial, a new trial can be added to the fine-tune run.

The new trial:

• Starts from the base model
• Uses the same configuration
• Has a new trial identity

When to Use

Use this when:

• Failure may be configuration-related
• You want a clean retry
• Comparing multiple attempts is desired

Result

• Failed trial remains visible for auditability
• New trial is tracked independently
• Best-performing trial can be selected later

See the screenshot below for an example of Add a New Trial After a Failed Trial.

Add Trials to an Existing Fine-Tune Run

A fine-tune run can contain multiple trials, each representing an independent training attempt.

Adding trials allows:

• Hyperparameter exploration
• Stability testing
• Performance comparison

All trials:

• Share the same base configuration
• Are evaluated independently
• Contribute to adapter selection

When to Use

Use this when:

• Running multiple attempts for robustness
• Evaluating sensitivity to randomness
• Comparing performance variability

Result

• Fine-tune run becomes a multi-trial experiment
• Best adapter can be selected based on evaluation metrics
• All trials remain traceable

See the screenshot below for an example of Add Trials to an Existing Fine-Tune Run.

Continue Fine-Tuning From a Specific Evaluation Point

Protean AI supports continuation fine-tuning, allowing training to resume from a specific evaluation snapshot with a new configuration. This creates a new training branch that builds on previously learned adapter weights.

What Changes

You may modify:

• Learning rate
• Epochs
• Batch size
• Regularization parameters
• Evaluation strategy

You may not change:

• Base model
• Dataset revision
• Adapter architecture

When to Use

Use continuation fine-tuning when:

• Initial training converged partially
• Additional learning is required
• You want to refine behavior without restarting

Examples:

• Lower learning rate for fine polishing
• Additional epochs after validation improvement
• Stabilizing a partially trained adapter

Result

• A new trial is created
• Training starts from selected evaluation snapshot
• Lineage links the new trial to its parent

See the screenshot below for an example of Continue Fine-Tuning From a Specific Evaluation Point.

Lineage and Traceability

All operations described above are fully tracked.

Protean AI records:

• Parent-child relationships between runs and trials
• Snapshot origin for resumed or continued runs
• Configuration deltas between branches

This ensures:

• Full auditability
• Reproducibility
• Clear understanding of model evolution

Summary

Protean AI fine-tuning is designed for controlled evolution, not one-off runs.

Operation	Purpose
Clone Configuration	Start fresh experiments
Resume Failed Trial	Recover from transient failures
Add New Trial	Retry cleanly
Add Trials	Compare multiple attempts
Continue From Snapshot	Incrementally refine learning

These capabilities allow teams to iterate confidently, recover safely, and build production-grade adapters without losing insight or control.
