A comparison to declarai would be great in your documentation.
Similar to what LMQL does with guidance etc.

Hi @jackmpcollins, I'm busy testing the new 0.18 release, and using litellm==1.33.4.
Magentic seems to struggle to parse functions that are decorated using list[str]
when using Anthropic's models via litellm
.
Reproducible example:
from magentic import prompt_chain
from magentic.chat_model.litellm_chat_model import LitellmChatModel
def get_menu():
return "On the menu today we have pizza, chips and burgers."
@prompt_chain(
"<instructions>You are a helpful model that precisely follows instructions. What is on the menu? You can use the get_menu function. Return your answer as a list of strings.</instructions>",
functions=[get_menu],
#model=LitellmChatModel(model="mistral/mistral-large-latest")
model=LitellmChatModel(model="anthropic/claude-3-sonnet-20240229")
)
def on_the_menu() -> list[str]: ...
on_the_menu()
This raises the following ValidationError:
ValidationError: 1 validation error for Output[list[str]]
value.0
Error iterating over object, error: ValidationError: 1 validation error for str
Invalid JSON: expected value at line 1 column 1 [type=json_invalid, input_value="'pizza'", input_type=str]
For further information visit https://errors.pydantic.dev/2.5/v/json_invalid [type=iteration_error, input_value=<generator object Iterabl...genexpr> at 0x13468ce40>, input_type=generator]
For further information visit https://errors.pydantic.dev/2.5/v/iteration_error
If I set litellm.verbose = True
, we get logging output that seems to indicate the final function call (to return the result in a list[str]
appears valid):

Is it a parsing oversight on Magentic's side? Or something deeper with litellm
?
I have defined an ENUM class like:
class SamsungPhoneModel(Enum):
"""Represents distinct Samsung Phone models"""
GALAXY_CORE_PLUS_350 = "GALAXY CORE PLUS 350"
GALAXY_FAME_LITE = "GALAXY FAME LITE"
GALAXY_S4 = "GALAXY S4"
UNDEFINED = ""
My prompt is: Classify the product title: {product_title} into a one of the specific model types as defined by SamsungPhoneModel.
If the product title is Galaxy S7 Active, which isn't present in Enum class. I would assume that Magentic should return "UNDEFINED" but it throws error that:
Failed to parse model output. You may need to update your prompt to encourage the model to return a specific type.
I can confirm that async
completion works via LiteLLM:
from litellm import acompletion

user_message = "Hello, who are you?"
messages = [{"content": user_message, "role": "user"}]

In light of the recent Claude-3 family of models being released by Anthropic...
How difficult do you envision adding Anthropic model support (API Ref) would be? Presumably as a AnthropicChatModel
? Annoyingly, the API isn't OpenAI-API compatible (but not by much), which makes it impossible to do a direct drop-in replacement.
I can potentially help contribute this as well.
Each function created using a magentic decorator (@prompt
, @chatprompt
, etc.) should have a corresponding span, as if it was also decorated with @tracer.start_as_current_span()
. The function arguments (with strings truncated) should be set as attributes on the span. The function name and a hash of the template string/messages should also be set as attributes on the span so that filtering by a function or a specific prompt template is possible.
The template hash should be available to users as a .template_hash
or similar method/property on their magentic functions so this is easily accessed. This should use hashlib.sha256
to be stable across Python versions and reproducible outside of magentic.
Documentation for the opentelemetry integration should include instructions on how users should wrap the functions they pass to the functions
argument. This is most useful for @prompt_chain
because it will make which function(s) the model decided to call visible in tracing. Maybe magentic should do this automatically?
Documentation for this should also include showing the traces in a UI, ideally one that can be easily installed and run locally. Looks like https://github.com/jaegertracing/jaeger is ideal.
Users should be able to configure whether magentic functions create spans, and whether/which function arguments are added as attributes to the spans.
I haven't found an easy way within the library to log messages sent to/from the model. When debugging prompts and trying to ensure the model's response properly serializes to a Pydantic model, having this level of logging available would be very helpful.
Hi there,
I'm occasionally running into issues with trying to do function calling using functions with **kwargs in their signature.
For example:
def do_something(x: str, y: str, **kwargs) -> str:
#< do something >
@prompt_chain(
"{query}",
functions=[do_something]
)
def chain(query: str) -> str
...
This leads to pydantic validation errors when the model occasionally doesn't pass in kwargs={}
when doing the function call:

Perhaps the **kwargs
argument could be marked as optional
in the Pydantic model that is inferred from the function signature? I am not able to modify the original functions, since they exist in an external library, and would like to avoid manually updating the __annotations__
attribute to remove the kwargs
argument using inspect
.
Perhaps another solution would be to allow users to specify their own input argument schemas as pydantic model for functions, but this might impact the API ergonomics a bit, so is probably undesireable.
Let me know, and thank you!
I have a project where I would like an LLM to iteratively improve a code snippet with the help of various tools.
One of those tools invokes a interpreter with the updated code that the LLM came up with, as often as required.
Once the interpreter invocation succeeds without error, there is no reason to return to the LLM-powerd function again, instead the LLM-powered function could simply return as well.
As far as I could tell from the docs it is currently not possible for user-written tools to do this.
The following comment makes me think something like this might be possible, since tool invocation is already used to terminate the execution of LLM-powered functions:
magentic uses function calling / tool calls to return most of these objects.
list[int]
gets converted into a function called "return_list_int" that GPT can choose to use, and if chosen the response gets parsed into alist[int]
by magentic.Originally posted by @jackmpcollins in #144 (comment)
Make prompt_chain
work with async functions. This will require awaiting coroutines when necessary, while allowing regular functions to be used too.
Usage would look like
from magentic import prompt_chain
async def get_current_weather(location, unit="fahrenheit"):
"""Get the current weather in a given location"""
# Pretend to query an API
return {
"location": location,
"temperature": "72",
"unit": unit,
"forecast": ["sunny", "windy"],
}
@prompt_chain(
"What's the weather like in {city}?",
functions=[get_current_weather],
)
async def describe_weather(city: str) -> str:
...
await describe_weather("Boston")
# 'The current weather in Boston is 72°F and it is sunny and windy.'
Hi,
I'm using magentic in a context where I cannot use on the OPENAI_API_KEY because I have multiple magentic calls running concurrently. Is there a way to set such a key on per-ChatModel
instance?
LiteLLM supports a bunch of params across different LLM providers and it'd be nice to be able to pass these through magentic.
(If you have a suggested pattern for the implementation, I'd be happy to throw up a PR.)
Due to the latest openai package update, you would likely encounter this error.
Temp fix:
pip install "openai<1.0.0"
Would be nice to integrate this with llamaindex.
Add an AnthropicChatModel
with improved support for tool calls and parsing streamed XML.
Currently, the Anthropic API requires the client to do the prompting and parsing for tool calling. Ideally, magentic contains no prompts so that these only exist in the LLM provider and user code. There is a package for using tools with Claude in alpha https://github.com/anthropics/anthropic-tools Anthropic is working on improving tool calls so might make sense to wait for this. https://docs.anthropic.com/claude/docs/functions-external-tools#upcoming-improvements

Hi 👋,
With the release of openai version 1.0, the OPENAI_API_BASE has been deprecated in favor of creating a client or similar constructs. This change is one of the reasons the Azure PR (#65) existed and this issue openai/openai-python#745 is still open.
The beauty of Magnetic, for me, has always been its simplicity and brevity. It stands out against more complex tools like Langchain or even the vanilla OpenAI library. I can typically achieve what I need in just four lines of code: import prompt, write decorator, define function, and call function. This is in stark contrast to the 10s of lines required for setting up clients, defining abstractions, and other setup processes that are peripheral to my goals.
The use of environment variables is pretty convenient. I could set them once for a project and forget about them.
In this context I want to ask the following question:
Is there a way to incorporate the functionality that we had with OPENAI_API_BASE with this new solution?
It would be very convenient to be using openai compatible apis by simply switching a value in a configuration (.env) file
When using vanilla openai I can pass the base_url when instantiating the client
openai.OpenAI(base_url="http://localhost:1234/v1")
in magentic's openai_chatcompletion_create
the client is generated with defaults
Would it be possible to do something like OpenAI(**some_settings)
to specify the arguments that OpenAI accepts on init?
Anyway, Thank you for your time and this excellent library. I look forward to any possible solutions or guidance you can offer.
Ideally this can be done by simply setting api_base
in OpenaiChatModel
. That avoids any new dependencies, and basically any new code. This is currently blocked on the Mistral API having a different format for tool_choice
than the OpenAI API. Issue for this mistralai/client-python#78
If that issue is not resolved, a new MistralChatModel
can be added that reuses all the code from OpenaiChatModel
but changes the default api_base
to the Mistral url and updates the usage of tool_calls
to match the Mistral API format.
I see that the deprecated functions
parameter is being used to pass in functions into the litellm completion function in magentic
.
Unfortunately this breaks support for certain models being use via liteLLM
, specifically Mistral-Large, which needs the new tools
and tool_choice
properties according to this comment.
Is it at all possible to add support for tools
to replace functions
which is now deprecated?
Hi,
I see tqdm is a required dependency. Is that a necessary one though? I'm trying to keep my dependency tree as lean as I can.
Thanks,
When using @prompt
, if the model returns an output that cannot be parsed into the return type or function arguments, or a string output when this is not accepted, the error message should be added as a new message in the chat and the query should be tried again within the @prompt
-decorated function's invocation. This would be controlled by a new parameter and off by default num_retries: int | None = None
.
This should just retry magentic exceptions for parsing responses / errors due to the LLM failing to generate valid output. OpenAI rate limiting errors, internet connection errors etc. should not be handled by this and instead users should use https://github.com/jd/tenacity or https://github.com/hynek/stamina to deal with those.
The "pip install magnetic" command, pulls another package... this one:
https://pypi.org/project/magnetic/
Newbie question... how do I install it?
Must I point pip to a certain repository?
Thanks!
Hello,
Terrific library, thank you for this!
I was hoping to be able to pass extra OpenAI parameters as I wanted to experiment with new reproducible output feature. But it seems we can't really interact with the underlying OpenAI instance. Is that something you'd consider propagating down at some point?
I'm using a Llama_cpp backend that imitates OpenAI's API. Its default max_tokens is set to 10 whereas OpenAI's default is set to None (I think). Without the ability to specify max_tokens, I cannot use Magentic with OSS LLMs :(
I wouldn't fire a new issue for this error:
ValueError: String was returned by model but not expected. You may need to update your prompt to encourage the model to return a specific type.
at this line:
verification_questions = await generate_verification_questions(query, baseline_response)is this issue related to that one? P.S. Here is the output of the previous Notebook cell:
Sure, here are a few politicians born in New York, New York: 1. Hillary Clinton 2. Donald Trump 3. Franklin D. Roosevelt 4. Rudy Giuliani 5. Theodore Roosevelt
It would be really useful to track the number of tokens consumed. But the information is not bubbled up. I gather this may not be feasible across providers though?
Hi,
After some testing I realized that it's not possible to use magentic
with Azure OpenAI. The reason is that in the following line the OpenAI
client is hard coded whereas an AzureOpenAI
client would be required. Same thing with the async versions of course.
See the Azure OpenAI example in their repo:
What would be the best way to support this in the code base? There is a OPENAI_API_TYPE
env var that could be checked to determine which client to use. If None
or "openai"
keep the same behavior, if "azure"
then use the Azure client. Is that too much of a hack?
Even better the openai
module exposes an api_type
constant that is type checked (I think).
Hi there,
I'm currently busy using magentic
and integrating it with parts of openbb
. Unfortunately, our docstrings are long and comprehensive, which often results in 400 errors when attempting to @prompt
for the function description being too long.
My attempted workaround was to use a decorator that replaces the docstring with a shortened version, while also preserving the type annotations, but unfortunately this still results in bad function calls that don't conform to the input schema:
# Workaround attempt
def use_custom_docstring(docstring):
def decorator(func):
def wrapper(*args, **kwargs):
return func(*args, **kwargs)
wrapper.__doc__ = docstring
wrapper.__annotations__ = func.__annotations__
return wrapper
return decorator
I suspect this is probably because the signature of the function is inspected directly, but I've not looked too deeply into the magentic
codebase to understand how the signature is parsed.
A neat solution to this would be to allow users to specify a function description, perhaps as a tuple (or whatever struct you think will work best):
@prompt(
PROMPT,
functions=[(my_function, "my function descriotion")],
model=OpenaiChatModel(model="gpt-4-1106-preview"),
)
def answer_question(world_state: str, question_id: str) -> str:
...
Thanks for a wonderful project!

I'm not sure exactly what's going wrong, or if anything is wrong in this repo - but having installed and tested litellm alone and got it working in 20 seconds - I suspect the issue is not in that repo...
so (I haven't checked, and I'm tired!) I suspect some initial data is getting passed incorrectly to litellm... but that's just my (uneducated) guess.

Hi @jackmpcollins,
Do you think it would be possible at all to implement stop
sequences (docs)?
These are incredibly useful when doing chain-of-thought style agentic prompting (eg. ReAct), where you want the model to stop generating at specific stop sequences. I have a hackathon project here that makes use of this pattern with this prompt, that utilizes a forked version of magentic
with a hacked and very basic implementation of stop sequences on a branch here for the non-async variant.
Hopefully this example demonstrates how powerful this can be: Using stop sequences, we can implement a ReAct agent with custom error handling, fault correction + more using a very thin abstraction layer. This essentially "unlocks" custom agent design using magentic
, and is loads simpler than doing the same thing using langchain
.
I'm more than happy to help on collaborating on this, but will need a bit of guidance on your end for the best way of implementing this.
Thanks again for a wonderful library!
All the best,
Michael.

This is on magentic==0.18 and litellm==1.33.4
Reproducible example:
from magentic import prompt_chain
from magentic.chat_model.litellm_chat_model import LitellmChatModel
def get_menu():
return "On the menu today we have pizza, chips and burgers."
@prompt_chain(
"<instructions>You are a helpful model that precisely follows instructions. What is on the menu? You can use the get_menu function. Return your answer as a list of strings.</instructions>",
functions=[get_menu],
model=LitellmChatModel(model="mistral/mistral-large-latest")
)
def on_the_menu() -> list[str]: ...
on_the_menu()
This leads to magentic
complaining that the get_menu
function is not known:

Thanks!
Hi! I’m working on Rubeus, a tool that could integrate with magnetic to enable easy swapping between different LLMs. It uses the same API signature as OpenAI, making integration straightforward. It also offers features like automatic fallbacks, retries, and load balancing. Would love to hear your thoughts!
INCORRECT PRODUCT CLASSIFICATION:
class SamsungPhoneModel(Enum):
"""Represents distinct Samsung Phone models"""
SAMSUNG_GALAXY_NOTE_9 = "SAMSUNG GALAXY NOTE 9"
classify_phone_model("Galaxy Note 9 Pro")
It returns: SAMSUNG_GALAXY_NOTE_9
If I ask GPT4 to extract model number without using Magentic, it returns Galaxy Note 9 Pro, which is UNDEFINED since its not in the ENUM class, but magentic is returning NOTE 9, that's incorrect.
Magentic works fine when I add to the class:
SAMSUNG_GALAXY_NOTE_9_PRO = "SAMSUNG GALAXY NOTE 9 PRO"

Would be neat to support environment variables for base url and necessary key/value parameters to support AI gateways, like Cloudflare's offering!
AI Gateway
Cloudflare AI Gateway Documentation
Cloudflare’s AI Gateway allows you to gain visibility and control over your AI apps. By connecting your apps to AI Gateway, you can gather insights on how people are using your application with analytics and logging and then control how your application scales with features such as caching, rate limiting, as well as request retries, model fallback, and more. Better yet - it only takes one line of code to get started.
