**DSPy** is the framework for solving advanced tasks with language models (LMs) and retrieval models (RMs). **DSPy** unifies techniques for **prompting** and **fine-tuning** LMs — and approaches for **reasoning**, **self-improvement**, and **augmentation with retrieval and tools**. All of these are expressed through modules that compose and learn.
To make this possible:
- **DSPy** provides **composable and declarative modules** for instructing LMs in a familiar Pythonic syntax. It upgrades "prompting techniques" like chain-of-thought and self-reflection from hand-adapted _string manipulation tricks_ into truly modular _generalized operations that learn to adapt to your task_.
- **DSPy** introduces an **automatic compiler that teaches LMs** how to conduct the declarative steps in your program. Specifically, the **DSPy compiler** will internally _trace_ your program and then **craft high-quality prompts for large LMs (or train automatic finetunes for small LMs)** to teach them the steps of your task.
The **DSPy compiler** _bootstraps_ prompts and finetunes from minimal data **without needing manual labels for the intermediate steps** in your program. Instead of brittle "prompt engineering" with hacky string manipulation, you can explore a systematic space of modular and trainable pieces.
For complex tasks, **DSPy** can routinely teach powerful models like `GPT-3.5` and local models like `T5-base` or `Llama2-13b` to be much more reliable at tasks. **DSPy** will compile the _same program_ into different few-shot prompts and/or finetunes for each LM.
If you want to see **DSPy** in action, **[open our intro tutorial notebook](intro.ipynb)**.

### Analogy to Neural Networks
When we build neural networks, we don't write manual _for-loops_ over lists of _hand-tuned_ floats. Instead, you might use a framework like [PyTorch](https://pytorch.org/) to compose declarative layers (e.g., `Convolution` or `Dropout`) and then use optimizers (e.g., SGD or Adam) to learn the parameters of the network.

## dspy.Predict
### Constructor
The constructor initializes the `Predict` class and sets up its attributes, taking in the `signature` and additional config options. If the `signature` is a string, it processes the input and output fields, generates instructions, and creates a template for the specified `signature` type.
```python
class Predict(Parameter):
def __init__(self, signature, **config):
self.stage = random.randbytes(8).hex()
self.signature = signature
self.config = config
self.reset()
if isinstance(signature, str):
inputs, outputs = signature.split("->")
## dspy.Assertion Helpers
### Assertion Handlers
The assertion handlers are used to control the behavior of assertions and suggestions in the DSPy framework. They can be used to bypass assertions or suggestions, handle assertion errors, and backtrack suggestions.
#### `noop_handler(func)`
This handler is used to bypass assertions and suggestions. When used, both assertions and suggestions will become no-operations (noops).
#### `bypass_suggest_handler(func)`
This handler is used to bypass suggestions only. If a suggestion fails, it will be logged but not raised. If an assertion fails, it will be raised.
#### `bypass_assert_handler(func)`
This handler is used to bypass assertions only. If an assertion fails, it will be logged but not raised. If a suggestion fails, it will be raised.
#### `assert_no_except_handler(func)`
This handler is used to ignore assertion failures and return None.
#### `suggest_backtrack_handler(func, bypass_suggest=True, max_backtracks=2)`
This handler is used for backtracking suggestions. It re-runs the latest predictor up to `max_backtracks` times, with updated signature if a suggestion fails.
#### `handle_assert_forward(assertion_handler, **handler_args)`
This function is used to handle assertions. It wraps the `forward` method of a module with an assertion handler.
#### `assert_transform_module(module, assertion_handler=default_assertion_handler, **handler_args)`
This function is used to transform a module to handle assertions. It replaces the `forward` method of the module with a version that handles assertions.
inputs, outputs = inputs.split(","), outputs.split(",")
inputs, outputs = [field.strip() for field in inputs], [field.strip() for field in outputs]
assert all(len(field.split()) == 1 for field in (inputs + outputs))
inputs_ = ', '.join([f"`{field}`" for field in inputs])
outputs_ = ', '.join([f"`{field}`" for field in outputs])
instructions = f"""Given the fields {inputs_}, produce the fields {outputs_}."""
inputs = {k: InputField() for k in inputs}
outputs = {k: OutputField() for k in outputs}
for k, v in inputs.items():
v.finalize(k, infer_prefix(k))
for k, v in outputs.items():
v.finalize(k, infer_prefix(k))
self.signature = dsp.Template(instructions, **inputs, **outputs)
```
**Parameters:**
- `signature` (_Any_): Signature of predictive model.
- `**config` (_dict_): Additional configuration parameters for model.
### Method
#### `__call__(self, **kwargs)`
This method serves as a wrapper for the `forward` method. It allows making predictions using the `Predict` class by providing keyword arguments.
**Paramters:**
- `**kwargs`: Keyword arguments required for prediction.
**Returns:**
- The result of `forward` method.
### Examples
```python
#Define a simple signature for basic question answering
class BasicQA(dspy.Signature):
"""Answer questions with short factoid answers."""
question = dspy.InputField()
answer = dspy.OutputField(desc="often between 1 and 5 words")
#Pass signature to Predict module
generate_answer = dspy.Predict(BasicQA)
# Call the predictor on a particular input.
question='What is the color of the sky?'
pred = generate_answer(question=question)
print(f"Question: {question}")
print(f"Predicted Answer: {pred.answer}")
```
## dspy.Retrieve
### Constructor
The constructor initializes the `Retrieve` class and sets up its attributes, taking in `k` number of retrieval passages to return for a query.
```python
class Retrieve(Parameter):
def __init__(self, k=3):
self.stage = random.randbytes(8).hex()
self.k = k
```
**Parameters:**
- `k` (_Any_): Number of retrieval responses
### Method
#### `__call__(self, *args, **kwargs):`
This method serves as a wrapper for the `forward` method. It allows making retrievals on an input query using the `Retrieve` class.
**Parameters:**
- `**args`: Arguments required for retrieval.
- `**kwargs`: Keyword arguments required for retrieval.
**Returns:**
- The result of the `forward` method.
### Examples
```python
query='When was the first FIFA World Cup held?'
# Call the retriever on a particular query.
retrieve = dspy.Retrieve(k=3)
topK_passages = retrieve(query).passages
print(f"Top {retrieve.k} passages for question: {query} \n", '-' * 30, '\n')
for idx, passage in enumerate(topK_passages):
print(f'{idx+1}]', passage, '\n')
```
# dspy.ChainOfThought
The constructor initializes the `ChainOfThought` class and sets up its attributes. It inherits from the `Predict` class and adds specific functionality for chain of thought processing.
Internally, the class initializes the `activated` attribute to indicate if chain of thought processing has been selected. It extends the `signature` to include additional reasoning steps and an updated `rationale_type` when chain of thought processing is activated.
```python
class ChainOfThought(Predict):
def __init__(self, signature, rationale_type=None, activated=True, **config):
super().__init__(signature, **config)
self.activated = activated
signature = self.signature
*keys, last_key = signature.kwargs.keys()
DEFAULT_RATIONALE_TYPE = dsp.Type(prefix="Reasoning: Let's think step by step in order to",
desc="${produce the " + last_key + "}. We ...")
rationale_type = rationale_type or DEFAULT_RATIONALE_TYPE
extended_kwargs = {key: signature.kwargs[key] for key in keys}
extended_kwargs.update({'rationale': rationale_type, last_key: signature.kwargs[last_key]})
self.extended_signature = dsp.Template(signature.instructions, **extended_kwargs)
```
**Parameters:**
- `signature` (_Any_): Signature of predictive model.
- `rationale_type` (_dsp.Type_, _optional_): Rationale type for reasoning steps. Defaults to `None`.
- `activated` (_bool_, _optional_): Flag for activated chain of thought processing. Defaults to `True`.
- `**config` (_dict_): Additional configuration parameters for model.
### Method
#### `forward(self, **kwargs)`
This method extends the parent `Predict` class' forward pass while updating the signature when chain of thought reasoning is activated or if the language model is a GPT3 model.
**Parameters:**
- `**kwargs`: Keyword arguments required for prediction.
**Returns:**
- The result of the `forward` method.
### Examples
```python
#Define a simple signature for basic question answering
class BasicQA(dspy.Signature):
"""Answer questions with short factoid answers."""
question = dspy.InputField()
answer = dspy.OutputField(desc="often between 1 and 5 words")
#Pass signature to ChainOfThought module
generate_answer = dspy.ChainOfThought(BasicQA)
# Call the predictor on a particular input.
question='What is the color of the sky?'
pred = generate_answer(question=question)
print(f"Question: {question}")
print(f"Predicted Answer: {pred.answer}")
```
## dspy.ChainOfThoughtWithHint
### Constructor
The constructor initializes the `ChainOfThoughtWithHint` class and sets up its attributes, inheriting from the `Predict` class. This class enhances the `ChainOfThought` class by offering an additional option to provide hints for reasoning. Two distinct signature templates are created internally depending on the presence of the hint.
```python
class ChainOfThoughtWithHint(Predict):
def __init__(self, signature, rationale_type=None, activated=True, **config):
super().__init__(signature, **config)
self.activated = activated
signature = self.signature
*keys, last_key = signature.kwargs.keys()
DEFAULT_HINT_TYPE = dsp.Type(prefix="Hint:", desc="${hint}")
DEFAULT_RATIONALE_TYPE = dsp.Type(prefix="Reasoning: Let's think step by step in order to",
desc="${produce the " + last_key + "}. We ...")
rationale_type = rationale_type or DEFAULT_RATIONALE_TYPE
extended_kwargs1 = {key: signature.kwargs[key] for key in keys}
extended_kwargs1.update({'rationale': rationale_type, last_key: signature.kwargs[last_key]})
extended_kwargs2 = {key: signature.kwargs[key] for key in keys}
extended_kwargs2.update({'hint': DEFAULT_HINT_TYPE, 'rationale': rationale_type, last_key: signature.kwargs[last_key]})
self.extended_signature1 = dsp.Template(signature.instructions, **extended_kwargs1)
self.extended_signature2 = dsp.Template(signature.instructions, **extended_kwargs2)
```
**Parameters:**
- `signature` (_Any_): Signature of predictive model.
- `rationale_type` (_dsp.Type_, _optional_): Rationale type for reasoning steps. Defaults to `None`.
- `activated` (_bool_, _optional_): Flag for activated chain of thought processing. Defaults to `True`.
- `**config` (_dict_): Additional configuration parameters for model.
### Method
#### `forward(self, **kwargs)`
This method extends the parent `Predict` class's forward pass, updating the signature dynamically based on the presence of `hint` in the keyword arguments and the `activated` attribute.
**Parameters:**
- `**kwargs`: Keyword arguments required for prediction.
**Returns:**
- The result of the `forward` method in the parent `Predict` class.
### Examples
```python
#Define a simple signature for basic question answering
class BasicQA(dspy.Signature):
"""Answer questions with short factoid answers."""
question = dspy.InputField()
answer = dspy.OutputField(desc="often between 1 and 5 words")
#Pass signature to ChainOfThought module
generate_answer = dspy.ChainOfThoughtWithHint(BasicQA)
# Call the predictor on a particular input alongside a hint.
question='What is the color of the sky?'
hint = "It's what you often see during a sunny day."
pred = generate_answer(question=question, hint=hint)
print(f"Question: {question}")
print(f"Predicted Answer: {pred.answer}")
```
## dspy.MultiChainComparison
### Constructor
The constructor initializes the `MultiChainComparison` class and sets up its attributes. It inherits from the `Predict` class and adds specific functionality for multiple chain comparisons.
The class incorporates multiple student attempt reasonings and concludes with the selected best reasoning path out of the available attempts.
```python
from .predict import Predict
from ..primitives.program import Module
import dsp
class MultiChainComparison(Module):
def __init__(self, signature, M=3, temperature=0.7, **config):
super().__init__()
self.M = M
signature = Predict(signature).signature
*keys, last_key = signature.kwargs.keys()
extended_kwargs = {key: signature.kwargs[key] for key in keys}
for idx in range(M):
candidate_type = dsp.Type(prefix=f"Student Attempt #{idx+1}:", desc="${reasoning attempt}")
extended_kwargs.update({f'reasoning_attempt_{idx+1}': candidate_type})
rationale_type = dsp.Type(prefix="Accurate Reasoning: Thank you everyone. Let's now holistically", desc="${corrected reasoning}")
extended_kwargs.update({'rationale': rationale_type, last_key: signature.kwargs[last_key]})
signature = dsp.Template(signature.instructions, **extended_kwargs)
self.predict = Predict(signature, temperature=temperature, **config)
self.last_key = last_key
```
**Parameters:**
- `signature` (_Any_): Signature of predictive model.
- `M` (_int_, _optional_): Number of student reasoning attempts. Defaults to `3`.
- `temperature` (_float_, _optional_): Temperature parameter for prediction. Defaults to `0.7`.
- `**config` (_dict_): Additional configuration parameters for model.
### Method
#### `forward(self, completions, **kwargs)`
This method aggregates all the student reasoning attempts and calls the predict method with extended signatures to get the best reasoning.
**Parameters:**
- `completions`: List of completion objects which include student reasoning attempts.
- `**kwargs`: Additional keyword arguments.
**Returns:**
- The result of the `predict` method for the best reasoning.
### Examples
```python
class BasicQA(dspy.Signature):
"""Answer questions with short factoid answers."""
question = dspy.InputField()
answer = dspy.OutputField(desc="often between 1 and 5 words")
# Example completions generated by a model for reference
completions = [
dspy.Prediction(rationale="I recall that during clear days, the sky often appears this color.", answer="blue"),
dspy.Prediction(rationale="Based on common knowledge, I believe the sky is typically seen as this color.", answer="green"),
dspy.Prediction(rationale="From images and depictions in media, the sky is frequently represented with this hue.", answer="blue"),
]
# Pass signature to MultiChainComparison module
compare_answers = dspy.MultiChainComparison(BasicQA)
# Call the MultiChainComparison on the completions
question = 'What is the color of the sky?'
final_pred = compare_answers(completions, question=question)
print(f"Question: {question}")
print(f"Final Predicted Answer (after comparison): {final_pred.answer}")
print(f"Final Rationale: {final_pred.rationale}")
```
## dspy.ReAct
### Constructor
The constructor initializes the `ReAct` class and sets up its attributes. It is specifically designed to compose the interleaved steps of Thought, Action, and Observation.
Internally, the class follows a sequential process: Thoughts (or reasoning) lead to Actions (such as queries or activities). These Actions then result in Observations (like results or responses), which subsequently feedback into the next Thought. This cycle is maintained for a predefined number of iterations.
```python
import dsp
import dspy
from ..primitives.program import Module
from .predict import Predict
class ReAct(Module):
def __init__(self, signature, max_iters=5, num_results=3, tools=None):
...
```
**Parameters:**
- `signature` (_Any_): Signature of the predictive model.
- `max_iters` (_int_, _optional_): Maximum number of iterations for the Thought-Action-Observation cycle. Defaults to `5`.
- `num_results` (_int_, _optional_): Number of results to retrieve in the action step. Defaults to `3`.
- `tools` (_List[dspy.Tool]_, _optional_): List of tools available for actions. If none is provided, a default `Retrieve` tool with `num_results` is used.
### Methods
#### `_generate_signature(self, iters)`
Generates a signature for the Thought-Action-Observation cycle based on the number of iterations.
**Parameters:**
- `iters` (_int_): Number of iterations.
**Returns:**
- A dictionary representation of the signature.
#### `act(self, output, hop)`
Processes an action and returns the observation or final answer.
**Parameters:**
- `output` (_dict_): Current output from the Thought.
- `hop` (_int_): Current iteration number.
**Returns:**
- A string representing the final answer or `None`.
#### `forward(self, **kwargs)`
Main method to execute the Thought-Action-Observation cycle for a given set of input fields.
**Parameters:**
- `**kwargs`: Keyword arguments corresponding to input fields.
**Returns:**
- A `dspy.Prediction` object containing the result of the ReAct process.
### Examples
```python
# Define a simple signature for basic question answering
class BasicQA(dspy.Signature):
"""Answer questions with short factoid answers."""
question = dspy.InputField()
answer = dspy.OutputField(desc="often between 1 and 5 words")
# Pass signature to ReAct module
react_module = dspy.ReAct(BasicQA)
# Call the ReAct module on a particular input
question = 'What is the color of the sky?'
result = react_module(question=question)
print(f"Question: {question}")

+            for k, v in outputs.items():
+                v.finalize(k, infer_prefix(k))
+
+            self.signature = dsp.Template(instructions, **inputs, **outputs)
+```
+
+**Parameters:**
+- `signature` (_Any_): Signature of predictive model.
+- `**config` (_dict_): Additional configuration parameters for model.
+
+### Method
+
+#### `__call__(self, **kwargs)`
+
+This method serves as a wrapper for the `forward` method. It allows making predictions using the `Predict` class by providing keyword arguments.
+
+**Paramters:**
+- `**kwargs`: Keyword arguments required for prediction.
+
+**Returns:**
+- The result of `forward` method.
+
+### Examples
+
+```python
+# Define a signature for a task
+class MyTask(dspy.Signature):
+    """This is a task."""
+    input1 = dspy.InputField()
+    output1 = dspy.OutputField()
+
+# Use the signature in a Predict module
+my_module = dspy.Predict(MyTask)
+
+# Call the predictor on a particular input.
+pred = my_module(input1="example input")
+
+print(f"Predicted Output: {pred.output1}")
+```
