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, student, examples, options, teacher)`
Returns	optimized artifact

C++

auto artifact = axllm::optimize(qa, client, train, axllm::object({}), &reflection);

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::AxBootstrapFewShot(options)`
Returns	optimizer engine

C++

axllm::AxBootstrapFewShot bootstrap(axllm::object({{"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::AxGEPA(reflection, options)`
Returns	optimizer engine

C++

axllm::AxGEPA engine(reflection_client);

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

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

Evaluator callback boundary used by generated optimizers.

Field	Value
Kind	`interface`
Ax concept	`OptimizerEvaluator`
API section	Optimizers
Form	`axllm::OptimizerEvaluator::evaluate(request)`
Returns	score/evidence result
