Creating messages

Messages sent to Gemini are made of a list of Parts, which can be text, or multimedia parts. Some multimedia files can be inlined as bytes (in particular images), but others need to be uploaded using the file API first. Although this is quite flexible, it’s a bit clunky, so we want to make it easier.

is_youtube_url

 is_youtube_url (url:str)

Check if the given URL is a valid YouTube video URL using urllib for parsing.

            return False
        # Embedded YouTube URL (e.g., https://www.youtube.com/embed/VIDEO_ID)
        elif parsed.path.startswith('/embed/'):
            video_id = parsed.path.split('/embed/')[1]
            return len(video_id) == 11

    # Shortened YouTube URL (e.g., https://youtu.be/VIDEO_ID)
    elif host == 'youtu.be':
        video_id = parsed.path.lstrip('/')
        return len(video_id) == 11
    return False

A nice quality of life improvement recently introduced is the ability of handling youtube link directly. This makes using the unique video understanding capabilities way more practical.

Notice that we cannot make mk_part a completely standalone function. Having access to the files API requires an a client. We could pass the genai.Client we have created before (or monkey patch mk_part into a class that has access to a client already), but for testing we create a new client each time.

Handling multiturn conversations

In order to generate content, the API expects as input a list of Content objects, each being a potentially multi Part message. A lot of stuff happens under the hood to automatically convert various kind of inputs into a list of Content, but there is an ambiguous case that we have to resolve: if our input is a list of strings, should it treat it as a multiturn conversation or should it be treated as a single user message with several text parts? We will adopt the following conventions:

A potential Content message is one of the following:

  • A Content or ContentDict object
  • A dictionary (with role and contents keys)
  • A list

The input to the client will be treated as a multiturn conversation only if it is a list and one of its items is a potential Content message, otehrwise the input will be treated as a single message.

A ripple, a gleam, a flash of dark fur,
An otter emerges, a whiskered blur.
From riverbank burrows, or kelp-forest deep,
Their playful existence, secrets they keep.

With sleek, streamlined bodies, built for the stream,
They dance with the currents, a liquid dream.
Webbed paws propel them, with effortless grace,
A ballet performed in their watery space.

They hunt with a fervor, a gleam in their eye,
For shellfish and fishes that swim swiftly by.
A stone on their chest, a makeshift small table,
They crack open their feast, a delectable fable.

They chatter and whistle, a language of clicks,
Communicating secrets with playful quick tricks.
They slide down the mudbanks, a joyful cascade,
In families they frolic, no longer afraid.

They hold to each other, afloat in the tide,
Connected and cozy, with nowhere to hide.
A symbol of joy, in their watery domain,
The otters are masters, of river and rain.

So watch for the sparkle, the splash and the call,
The otter’s bright spirit, enchanting us all.
A reminder to play, to connect and to thrive,
And find simple pleasures, in being alive.

# This is for compatibility with Claudette. We want _stream(s) to be a coroutine, not an async generator
@patch
async def _stream(self: genai.models.AsyncModels, s, think): return self._astream(s, think)

To keep the behaviour coherent with Claudette’s when in streaming mode, we should only yield the text of the chunks, rather than the full response. The _stream method essentially replicates the text_stream of Anthropic’s SDK. Since there is no to Claude’s get_final_message we have to store the chunk parts as they are yielded. After the stream is exhausted, we substitute the saved parts into the final response (which contains the correct usage as well, and pass the result through _r)

    return self._stream(r) if stream else self._r(r)

We use the _gen method to get around the fact that streaming in genai is handled by different methods, rather than a parameter.

Tools and function calling

There are two ways of managing function calling. The other is to actually build the function declaration. The first approach has the advantage of enabling automatic function calling, meaning that whenever the LLM decides that the function needs to be called, it will call and get the result back. The main drawback is that it realies on the types.FunctionDeclaration.from_callable method, which is quite limited (mainly, it does not add descriptions to the parameters, most likely relying on docstrings following Google’s style guide).

The second approach requires manually declaring the function, but this won’t be picked up by the automatic function calling, so requires manually enabling the function loop (extracting the function calls from the response, calling the function and passing it back to the LLM).

Tool prepping

def add1(
    a:int, # the 1st number to add
    b=0,   # the 2nd number to add
)->int:    # the result of adding `a` to `b`
    "Sums two numbers."
    return a+b

def add2(
    a:int, # the 1st number to add
    b:int=0,   # the 2nd number to add
)->int:    # the result of adding `a` to `b`
    "Sums two numbers."
    return a+b

def add3(
    a:int, # the 1st number to add
    b:int,   # the 2nd number to add
)->int:    # the result of adding `a` to `b`
    "Sums two numbers."
    return a+b

try:
    f_decl = types.FunctionDeclaration.from_callable(callable=add1, client=c)
except:
    try:
        f_decl = types.FunctionDeclaration.from_callable(callable=add2, client=c)
    except:
        f_decl = types.FunctionDeclaration.from_callable(callable=add3, client=c)
        

f_decl.to_json_dict()
{'description': 'Sums two numbers.',
 'name': 'add3',
 'parameters': {'properties': {'a': {'type': 'INTEGER'},
   'b': {'type': 'INTEGER'}},
  'type': 'OBJECT'}}
docments(add1, full=True, returns=False)
{ 'a': { 'anno': <class 'int'>,
         'default': <class 'inspect._empty'>,
         'docment': 'the 1st number to add'},
  'b': { 'anno': <class 'int'>,
         'default': 0,
         'docment': 'the 2nd number to add'}}

Notice that types.FunctionDeclaration.from_callable:

  1. Cannot infer the parameter type from the default value (while docments can)
  2. Does not use the default values at all: in fact adding default values to a function declaration passed to the Gemini API will raise an error, although the LLM would be able to use (and in fact does use if it’s passed), the “required” field of the “parameters”, which again could be inferred.

goog_doc

 goog_doc (f:<built-infunctioncallable>)

Builds the docstring for a docment style function following Google style guide

Type Details
f callable A docment style function
Returns str Google style docstring

When passing a function as a tool, the API will only access the function signature and docstring to build the FunctionDeclaration, so unless they are part of the docstring, the LLM has no way of knowing what the arguments or the returned value are. Assuming that Gemini models will have seen quite a lot of google code, and considering the examples in the documentation, it’s probably a good idea to turn the docstrings of tools into a format compatible with the style guide.

    if hasattr(f_decl.parameters, "required"): f_decl.parameters.required = required_params
    return f_decl

To prepare a function to be used as a function declaration, it needs to be stripped of default values and all the arguments need to be annotated. Turning the docstrings in a Google compatible format makes sure that the result can be used for automatic function calling. We rely on FunctionDeclaration.from_callable either implicitly (when passing the prepped function to the LLM) or implicitly to do the necessary type conversions of the annotations (i.e. turning a float into NUMBER, a str into STRING etc.). If building the function declaration explicitly, we can also enrich it with information from the original function (namely the presence of default values and the arguments docments that can be added paramters objects).

Since we can pass several tools at once, and functions can be handled directly using the automated function calling from the SDK itself, in order to keep the API consistent with Claudette and Cosette, we need to add an intermediate layer to prepare the tools. Notice that this is defining each single function as a tool, while in principle we could group several into a tool (so that we can force the LLM to use a subset of tools).

Automatic Function Calling

If instead of tools, we pass functions, we can rely on the SDK Automatic function calling, which essentially completes the whole tool loop by itself (checking for errors as well). The main drawback is that it is more limited in terms of function parameters types and it completely relies on the docstring of the function (although we turn the docments comments into a more complete docstring while prepping the function). In other words, when automatically building turning the function into a tool, the parameters descriptions are not set when using AFC. It is uncler how much this might affect the function calling performance

I am sorry, I am unable to help with that. I can only calculate sums and products.

Notice how if passing tools to the calls, Gemini assumes that its sole purpose is to call those tools.

Okay, here are some fun and engaging games you can play with your dog indoors on a rainy day, catering to different energy levels and preferences:

For the Energetic Pup:

* Indoor Fetch/Hallway Fetch: If you have a long hallway or a spacious room, you can still play fetch! Use a soft toy or a rolled-up sock to prevent damage. Keep the throws short and controlled.
* Tug-of-War: A classic! Tug-of-war is a great way to burn energy and build a bond. Make sure you let your dog win sometimes and avoid jerking the toy too hard to protect their teeth and neck.
* Agility Course (DIY): Use household items like pillows, blankets draped over chairs, tunnels made from cardboard boxes, or even a broom laid across two objects to create a mini agility course. Guide your dog through it using treats and praise. Start slow and gradually increase the difficulty.
* Find the Treat/Toy: Hide treats or a favorite toy around the house and encourage your dog to sniff them out. Start with easy hides and gradually make them more challenging.
* Flirt Pole: If you have a flirt pole (a toy attached to a long pole), you can use it indoors (carefully!). This is a great way to get a dog moving and engaged. Make sure you have enough space and be mindful of your surroundings.

For the Mentally Stimulated Dog:

* Puzzle Toys: These are a lifesaver on rainy days! There are many different types, from simple treat-dispensing balls to more complex puzzles that require your dog to solve problems to get to the reward. Examples include:
* Kong Wobbler: A classic that dispenses treats as it wobbles.
* Nina Ottosson Puzzles: A popular brand with various difficulty levels.
* Snuffle Mats: A mat with fabric strips where you can hide treats for your dog to find.
* Training Games: Rainy days are perfect for reinforcing basic commands or teaching new tricks. Keep training sessions short, positive, and reward-based.
* “Sit,” “Stay,” “Come,” “Down” Practice these commands in different locations around the house.
* “Leave It” A crucial command for safety and impulse control.
* “Spin,” “Shake,” “Play Dead” Fun tricks that impress and engage your dog.
* Name Game: Teach your dog the names of their toys. Hold up a toy, say its name, and reward your dog when they touch it. Gradually increase the number of toys they have to differentiate between.
* “Which Hand?” Hide a treat in one hand and let your dog sniff both hands. When they indicate which hand has the treat, reward them.

For the Relaxed Dog (or to wind down after playtime):

* Massage/Grooming: A gentle massage or grooming session can be very relaxing for your dog.
* Cuddle Time: Sometimes, the best rainy day activity is simply cuddling up on the couch with your furry friend.
* Listen to Calming Music/Sounds: There are playlists specifically designed for dogs that can help them relax.
* Chew Toy Session: Provide a long-lasting chew toy to keep your dog occupied and help them relax.

Important Considerations:

* Space: Consider the size of your home and choose games that fit the available space.
* Your Dog’s Personality: Tailor the games to your dog’s individual preferences and energy levels. Some dogs love fetch, while others prefer puzzle toys.
* Safety: Make sure the environment is safe for your dog. Remove any hazards and use soft toys to prevent injuries.
* Supervision: Always supervise your dog during playtime, especially when using new toys or playing new games.
* Breaks: Give your dog breaks during playtime to prevent them from getting overtired.
* End on a Positive Note: Always end playtime with praise and a reward.

Have fun playing with your dog on those rainy days! A little creativity can go a long way in keeping your furry friend happy and entertained.
