It uses LLM-based reflection and Pareto-aware search to evolve robust, high-performing variants with minimal evaluations. See the [GEPA paper](https://arxiv.org/abs/2507.19457) and [GEPA repo](https://github.com/gepa-ai/gepa) for details. + +## When to Use GEPA in Optimas +- You want to optimize prompts or other text components in a modular AI system. +- You want to leverage LLM-based reflection and feedback for prompt evolution. +- You are using DSPy modules (recommended, easiest integration), or you are an advanced user with a custom text-based system. + +## Using GEPA with DSPy (Default Integration) +Optimas natively supports GEPA as a prompt optimizer for DSPy-based components. To use it: + +1. Set `prompt_optimizer: gepa` in your config or CLI arguments. +2. (Optional) Configure GEPA-specific options, e.g.: + ```yaml + prompt_optimizer: gepa + gepa_auto: medium # or set gepa_max_metric_calls, gepa_num_iters, etc. + gepa_reflection_minibatch_size: 5 + gepa_log_dir: ./gepa_logs + gepa_use_wandb: true + gepa_wandb_api_key: "your_wandb_api_key" + gepa_wandb_init_kwargs: + project: "my-gepa-project" + entity: "my-wandb-entity" + ``` +3.

Implement the `GEPAAdapter` interface (see [gepa/core/adapter.py](https://github.com/gepa-ai/gepa/blob/main/src/gepa/core/adapter.py)). Your adapter must provide: + - `evaluate(batch, candidate, capture_traces)` + - `make_reflective_dataset(candidate, eval_batch, components_to_update)` + - (Optional) `propose_new_texts(...)` +2. Modify or subclass the Optimas optimizer to inject your adapter instance when calling GEPA. +3. Pass your adapter and config as needed.

By providing framework-agnostic GEPA support with rich, framework-specific feedback, it enables users to leverage the power of GEPA optimization regardless of their chosen AI framework. The implementation maintains backward compatibility while opening up new possibilities for cross-framework optimization strategies. + +This implementation transforms Optimas from a DSPy-centric optimization tool into a truly universal platform for optimizing compound AI systems across any supported framework. \ No newline at end of file diff --git a/docs/gepa_adapter.md b/resources/guides/gepa_adapter.md similarity index 100% rename from docs/gepa_adapter.md rename to resources/guides/gepa_adapter.md diff --git a/resources/testing/test_gepa_integration.py b/resources/testing/test_gepa_integration.py new file mode 100644 index 0000000..781f05c --- /dev/null +++ b/resources/testing/test_gepa_integration.py @@ -0,0 +1,405 @@ +#!/usr/bin/env python3 +""" +GEPA Integration Verification Test + +This script verifies that GEPA integration doesn't break any existing functionality +and that new GEPA features work correctly.

It uses LLM-based reflection and Pareto-aware search to evolve robust, high-performing variants with minimal evaluations. See the [GEPA paper](https://arxiv.org/abs/2507.19457) and [GEPA repo](https://github.com/gepa-ai/gepa) for details. - -## When to Use GEPA in Optimas -- You want to optimize prompts or other text components in a modular AI system. -- You want to leverage LLM-based reflection and feedback for prompt evolution. -- You are using DSPy modules (recommended, easiest integration), or you are an advanced user with a custom text-based system. - -## Using GEPA with DSPy (Default Integration) -Optimas natively supports GEPA as a prompt optimizer for DSPy-based components. To use it: - -1. Set `prompt_optimizer: gepa` in your config or CLI arguments. -2. (Optional) Configure GEPA-specific options, e.g.: - ```yaml - prompt_optimizer: gepa - gepa_auto: medium # or set gepa_max_metric_calls, gepa_num_iters, etc. - gepa_reflection_minibatch_size: 5 - gepa_log_dir: ./gepa_logs - gepa_use_wandb: true - gepa_wandb_api_key: "your_wandb_api_key" - gepa_wandb_init_kwargs: - project: "my-gepa-project" - entity: "my-wandb-entity" - ``` -3. Run your Optimas pipeline as usual. GEPA will optimize all DSPy-based components. - -## Using GEPA with a Custom Adapter (Advanced) -If you want to optimize a non-DSPy system (e.g., your own text-based pipeline), you can implement a custom `GEPAAdapter`: - -1. Implement the `GEPAAdapter` interface (see [gepa/core/adapter.py](https://github.com/gepa-ai/gepa/blob/main/src/gepa/core/adapter.py)). Your adapter must provide: - - `evaluate(batch, candidate, capture_traces)` - - `make_reflective_dataset(candidate, eval_batch, components_to_update)` - - (Optional) `propose_new_texts(...)` -2. Modify or subclass the Optimas optimizer to inject your adapter instance when calling GEPA. -3. Pass your adapter and config as needed. Example (Python): - ```python - from gepa.adapters.default_adapter import DefaultAdapter - my_adapter = DefaultAdapter(model="openai/gpt-4o") - # ... - # In your optimizer logic: - gepa_result = gepa.optimize( - seed_candidate=seed, - trainset=trainset, - valset=valset, - adapter=my_adapter, - # ...other config... - ) - ``` -4. See the [GEPA documentation](https://github.com/gepa-ai/gepa) for more on adapters. - -## Configuring Logging and Experiment Tracking -- Use `gepa_logger` to pass a custom logger instance (advanced). -- Use `gepa_use_wandb`, `gepa_wandb_api_key`, and `gepa_wandb_init_kwargs` to control Weights & Biases logging. -- Example YAML: - ```yaml - gepa_use_wandb: true - gepa_wandb_api_key: "your_wandb_api_key" - gepa_wandb_init_kwargs: - project: "my-gepa-project" - entity: "my-wandb-entity" - ``` - -## Example: Minimal DSPy GEPA Config -```yaml -prompt_optimizer: gepa -gepa_auto: light -gepa_log_dir: ./gepa_logs -``` - -## Further Reading -- [GEPA Documentation](https://github.com/gepa-ai/gepa) -- [DSPy GEPAAdapter Example](https://github.com/stanfordnlp/dspy/blob/main/dspy/teleprompt/gepa/gepa_utils.py) -- [Optimas README](../README.md) diff --git a/resources/testing/test_gepa_integration.py b/resources/testing/test_gepa_integration.py deleted file mode 100644 index 781f05c..0000000 --- a/resources/testing/test_gepa_integration.py +++ /dev/null @@ -1,405 +0,0 @@ -#!/usr/bin/env python3 -""" -GEPA Integration Verification Test - -This script verifies that GEPA integration doesn't break any existing functionality -and that new GEPA features work correctly.
