optimize() API

GEPA, Pareto, artifact, and optimizer APIs.

Most Used

Convenience optimizer helper that composes AxBootstrapFewShot before AxGEPA and returns an artifact without applying final component changes.

Field	Value
Kind	`function`
Ax concept	`optimize`
API section	Optimizers
Form	`axllm.Optimize(program, examples, options)`
Returns	Value

artifact, err := axllm.Optimize(qa, train, map[string]axllm.Value{"studentAI": client})

Few-shot demonstration optimizer that selects successful evaluator rollouts before prompt/component evolution.

Field	Value
Kind	`type`
Ax concept	`AxBootstrapFewShot`
API section	Optimizers
Form	`axllm.NewBootstrapFewShot(options)`
Returns	optimizer engine

bootstrap := axllm.NewBootstrapFewShot(map[string]axllm.Value{"qualityThreshold": 0.7})

Generated GEPA optimizer engine with Core-owned reflection, Pareto, bootstrap, and selector-state behavior.

Field	Value
Kind	`type`
Ax concept	`AxGEPA`
API section	Optimizers
Form	`axllm.NewGEPA(reflection, options)`
Returns	optimizer engine

engine := axllm.NewGEPA(reflectionClient, nil)

Optimizer boundary consumed by AxGen, AxAgent, and AxFlow optimization helpers.

Field	Value
Kind	`interface`
Ax concept	`OptimizerEngine`
API section	Optimizers
Form	`OptimizerEngine.Optimize(request, evaluator)`
Returns	optimized artifact

Evaluator callback boundary used by generated optimizers.

Field	Value
