-# Daily AI SDK
+# dailyai — an open source framework for real-time, multi-modal, conversational AI applications

+Build things like this:
 
-_Demo Video to come_
+[![AI-powered voice patient intake for healthcare](https://img.youtube.com/vi/lDevgsp9vn0/0.jpg)](https://www.youtube.com/watch?v=lDevgsp9vn0)
 
-With built-in support for many of the best AI platforms (or [add your own](/docs)):
+**`dailyai` started as a toolkit for implementing generative AI voice bots.** Things like personal coaches, meeting assistants, story-telling toys for kids, customer support bots, and snarky social companions.
 
-- Azure - DALL-E, ChatGPT, and Azure AI Text-to-Speech
-- Deepgram - Speech-to-text, and Aura text-to-speech
-- Eleven Labs text-to-speech
-- Fal.ai image generation
-- OpenAI DALL-E and ChatGPT
-- Whisper local speech-to-text
+In 2023 a *lot* of us got excited about the possibility of having open-ended conversations with LLMs. It became clear pretty quickly that we were all solving the same [low-level problems](https://www.daily.co/blog/how-to-talk-to-an-llm-with-your-voice/):
+- low-latency, reliable audio transport
+- echo cancellation
+- phrase endpointing (knowing when the bot should respond to human speech)
+- interruptibility
+- writing clean code to stream data through "pipelines" of speech-to-text, LLM inference, and text-to-speech models
 
-## Step 1: Get Started
+As our applications expanded to include additional things like image generation, function calling, and vision models, we started to think about what a complete framework for these kinds of apps could look like.
 
-## Build/Install
+Today, `dailyai` is:
+
+1. a set of code building blocks for interacting with generative AI services and creating low-latency, interruptible data pipelines that use multiple services
+2. transport services that moves audio, video, and events across the Internet
+3. implementations of specific generative AI services
+
+Currently implemented services:
+- Speech-to-text
+  - Deepgram
+  - Whisper
+- LLMs
+  - Azure
+  - OpenAI
+- Image generation
+  - Azure
+  - Fal
+  - OpenAI
+- Text-to-speech
+  - Azure
+  - Deepgram
+  - ElevenLabs
+- Transport
+  - Daily
+  - Local (in progress, intended as a quick start example service)
+
+If you'd like to [implement a service]((https://github.com/daily-co/daily-ai-sdk/tree/main/src/dailyai/services)), we welcome PRs! Our goal is to support lots of services in all of the above categories, plus new categories (like real-time video) as they emerge.
+
+## Getting started
+
+Today, the easiest way to get started with `dailyai` is to use [Daily](https://www.daily.co/) as your transport service. This toolkit started life as an internal SDK at Daily and millions of minutes of AI conversation have been served using it and its earlier prototype incarnations. (The [transport base class](https://github.com/daily-co/daily-ai-sdk/blob/main/src/dailyai/transports/abstract_transport.py) is easy to extend, though, so feel free to submit PRs if you'd like to implement another transport service.)
+
+```
+# install the module
+pip install dailyai
+
+# set up an .env file with API keys
+cp dot-env.template .env
+```
+
+By default, in order to minimize dependencies, only the basic framework functionality is available. Some third-party AI services require additional
+dependencies that you can install with:
+
+```
+pip install dailyai[option,...]
+```
+
+Your project may or may not need these, so they're made available as optional requirements. Here is a list:
+
+- **AI services**: `anthropic`, `azure`, `fal`, `openai`, `playht`, `silero`, `whisper`
+- **Transports**: `daily`, `local`, `websocket`
+
+## Code examples
+
+There are two directories of examples:
+
+- [foundational](https://github.com/daily-co/daily-ai-sdk/tree/main/examples/foundational) — demos that build on each other, introducing one or two concepts at a time
+- [starter apps](https://github.com/daily-co/daily-ai-sdk/tree/main/examples/starter-apps) — complete applications that you can use as starting points for development
+
+Before running the examples you need to install the dependencies (which will install all the dependencies to run all of the examples):
+
+```
+pip install -r {env}-requirements.txt
+```
+
+To run the example below you need to sign up for a [free Daily account](https://dashboard.daily.co/u/signup) and create a Daily room (so you can hear the LLM talking). After that, join the room's URL directly from a browser tab and run:
+
+```
+python examples/foundational/02-llm-say-one-thing.py
+```

-## Running the samples
+### Running tests
 
-Tou can run the simple sample like so:
+From the root directory, run:
 
 ```
-python src/examples/theoretical-to-real/01-say-one-thing.py -u <url of your Daily meeting> -k <your Daily API Key>
-```
-## Overview
-
-The Daily AI SDK allows you to build applications that can participate in WebRTC sessions and interact with AI Services. Some examples of what you can build with this:
-
-- conversational bots that interact 1:1 with a user, using voice recognition and text-to-speech
-- assistant bots that aggregate transcriptions from multiple participants in a meeting and provide realtime summaries or other AI-generated output.
-- image-recognition bots
-- etc
-
-## Concepts
-
-### Transport Service
-
-The SDK provides one “transport service”, which is a wrapper around Daily’s `daily-python` client (tk add link). You can use this service to listen for events related to a WebRTC session, such as “a participant joined the meeting”.
-The transport service also exposes a send queue, and a receive queue. You can use the send queue to send audio and video to the WebRTC session, and you can listen to the receive queue to see audio, video and transcription data from the WebRTC session.
-
-### AI Services
-
-The AI Service classes provide wrappers around various AI providers, and allow you to query LLMs, convert text to speech and make images from text. The audio and images can then be placed on the transport service’s send queue, where they’ll be sent to the WebRTC session.
-
-### Queue Frames
-
-Communication between the transport service and AI services, and between various AI services, takes place in Queue Frames. These frames contain an indication of the type of data as well as the data itself.
-
-## Using Transports, AI Services and Frames
-
-AI Services all define a `.run` method. This method consumes and generates `QueueFrame` frames. The kind of frames that can be consumed and generated depend on the kind of service. For instance, an LLM AI Service consumes `LLM_MESSAGE` frames (which define a history of interaction with an LLM) and emit `TEXT` frames (the response from the LLM).
-
-The `.run` method is an `AsyncIterable`, and it takes an `iterable`, `AsyncIterable` or `asyncio.Queue` that produces QueueFrames as a parameter. This makes it easy to chain AI Services, and consume input from the Transport’s `receive_queue` .
-
-AI Services also have a `.run_to_queue` method. This method is not an AsyncIterable, but instead sends processed QueueFrames to a queue. This makes it easy to send the output of an AI Service to the Transport’s `send_queue`.
-
-AI Services also define convenience functions that let you bypass creating QueueFrames for some simple cases (eg. using the TTS service to convert a string to audio output and send that audio to the transport’s `send_queue`). See below for examples.
-
-## Examples
-
-### Say Something
-
-The base TTS AI service exposes a `.say` method. After creating a transport and TTS service, you can use this method like so:
-
-```
-transport = DailyTransportService(...)
-tts = AzureTTSService()
-await tts.say("hello world", transport.send_queue)
+pytest --doctest-modules --ignore-glob="*to_be_updated*" src tests
 ```
 
-This will call the TTS service to render the text to audio frames, then put the audio frames on the transport’s send queue. The transport will then send those frames along to the WebRTC session.
+## Setting up your editor
 
-### Speak an LLM response
+This project uses strict [PEP 8](https://peps.python.org/pep-0008/) formatting.
 
-Given a system prompt contained in a `messages` array, you can emit the LLM’s response as audio with a chain like this:
+### Emacs
 
-```
-transport = DailyTransportService(...) # setup parameters omitted
-tts = AzureTTSService()
-llm = AzureLLMService()
-messages = [...] # system prompt omitted for brevity
+You can use [use-package](https://github.com/jwiegley/use-package) to install [py-autopep8](https://codeberg.org/ideasman42/emacs-py-autopep8) package and configure `autopep8` arguments:
 
-await tts.run_to_queue(
-  transport.send_queue,
-  llm.run([QueueFrame.LLM_MESSAGES, messages])
-)
+```elisp
+(use-package py-autopep8
+  :ensure t
+  :defer t
+  :hook ((python-mode . py-autopep8-mode))
+  :config
+  (setq py-autopep8-options '("-a" "-a", "--max-line-length=100")))
 ```
 
-In this code, the LLM service object sends the messages to Azure’s OpenAI implementation, which streams chunks back asynchronously. Those chunks are aggregated by the TTS Service to ensure the best audio response (TTS works best when it gets complete sentence, so it can inflect correctly), then sent to Azure’s TTS service, converted to audio frames, and sent to the WebRTC session via the Daily transport.
+`autopep8` was installed in the `venv` environment described before, so you should be able to use [pyvenv-auto](https://github.com/ryotaro612/pyvenv-auto) to automatically load that environment inside Emacs.
 
-### Pre-cache an LLM response
-
-Sometimes LLMs can be slower than we’d like for natural-feeling communication. Here’s an example where we take advantage of the time it takes to speak some pre-defined text to get a head start on the LLM response:
-
-(TK link to 04- sample)
-
-In this sample, we set up a buffer queue to receive the audio frames from the LLM response before while we are joining the call and start an asynchronous task to start filling this buffer:
-
-```
-    buffer_queue = asyncio.Queue()
-    llm_response_task = asyncio.create_task(
-        elevenlabs_tts.run_to_queue(
-            buffer_queue,
-            llm.run([QueueFrame(FrameType.LLM_MESSAGE, messages)]),
-            True,
-        )
-    )
-```
-
-Then, when we’ve joined the call, we speak the static text:
-
-```
-        await azure_tts.say("My friend...", transport.send_queue)
-```
-
-As that text is being spoken, the asynchronous LLM task continues in the background. When the text is done, we pull the frames off the buffer queue and put them in the transport’s `send_queue`:
-
-```
-        async def buffer_to_send_queue():
-            while True:
-                frame = await buffer_queue.get()
-                await transport.send_queue.put(frame)
-                buffer_queue.task_done()
-                if frame.frame_type == FrameType.END_STREAM:
-                    break
-
-        await asyncio.gather(llm_response_task, buffer_to_send_queue())
+```elisp
+(use-package pyvenv-auto
+  :ensure t
+  :defer t
+  :hook ((python-mode . pyvenv-auto-run)))
 
 ```
 
-One thing to note here is the last parameter to `run_to_queue` in the first code clause above: this causes the `run_to_queue` method to send an `END_STREAM` frame when it’s done rendering. This lets us know when to stop our `buffer_to_send_queue` task above.

 # Daily AI SDK Architecture Guide
 
+## Frames
+
+Frames can represent discrete chunks of data, for instance a chunk of text, a chunk of audio, or an image. They can also be used to as control flow, for instance a frame that indicates that there is no more data available, or that a user started or stopped talking. They can also represent more complex data structures, such as a message array used for an LLM completion.
+
+## FrameProcessors
+
+Frame processors operate on frames. Every frame processor implements a `process_frame` method that consumes one frame and produces zero or more frames. Frame processors can do simple transforms, such as concatenating text fragments into sentences, or they can treat frames as input for an AI Service, and emit chat completions based on message arrays or transform text into audio or images.
+
+## Pipelines
+
+Pipelines are lists of frame processors that read from a source queue and send the processed frames to a sink queue. A very simple pipeline might chain an LLM frame processor to a text-to-speech frame processor, with a transport's send queue as its sync. Placing LLM message frames on the pipeline's source queue will cause the LLM's response to be spoken. See example #2 for an implementation of this.
+
+## Transports
+
+Transports provide a receive queue, which is input from "the outside world", and a sink queue, which is data that will be sent "to the outside world". The `LocalTransportService` does this with the local camera, mic, display and speaker. The `DailyTransportService` does this with a WebRTC session joined to a Daily.co room.

+# A Frame's Progress
+
+1. A user says “Hello, LLM” and the cloud transcription service delivers a transcription to the Transport.
+![A transcript frame arrives](images/frame-progress-01.png)
+
+2. The Transport places a Transcription frame in the Pipeline’s source queue.
+![Frame in source queue](images/frame-progress-02.png)
+
+3. The Pipeline passes the Transcription frame to the first Frame Processor in its list, the LLM User Message Aggregator.
+![To UMA](images/frame-progress-03.png)
+
+4. The LLM User Message Aggregator updates the LLM Context with a `{“user”: “Hello LLM”}` message.
+![Update context](images/frame-progress-04.png)
+
+5. The LLM User Message Aggregator yields an LLM Message Frame, containing the updated LLM Context. The Pipeline passes this frame to the LLM Frame Processor.
+![Update context](images/frame-progress-05.png)
+
+6. The LLM Frame Processor creates a streaming chat completion based on the LLM context and yields the first chunk of a response, Text Frame with the value “Hi, “. The Pipeline passes this frame to the TTS Frame Processor. The TTS Frame Processor aggregates this response but doesn’t yield anything, yet, because it’s waiting for a full sentence.
+![LLM yields Text](images/frame-progress-06.png)
+
+7. The LLM Frame Processor yields another Text Frame with the value “there.”. The Pipeline passes this frame to the TTS Frame Processor.
+![LLM yields more Text](images/frame-progress-07.png)
+
+8. The TTS Frame Processor now has a full sentence, so it starts streaming audio based on “Hi, there.” It yields the first chunk of streaming audio as an Audio frame, which the Pipeline passes to the LLM Assistant Message Aggregator.
+![TTS yields Audio](images/frame-progress-08.png)
+
+9. The LLM Assistant Message Aggregator doesn’t do anything with Audio frames, so it immediately yields the frame, unchanged. This is the convention for all Frame Processors: frames that the processor doesn’t process should be immediately yielded.
+![pass-through](images/frame-progress-09.png)
+
+10. The Pipeline places the first Audio frame in its sink queue, which is being watched by the Transport. Since the frame is now in a queue, the Pipeline can continue processing other frames. Note that the source and sink queues form a sort of “boundary of concurrent processing” between a Pipeline and the outside world. In a Pipeline, Frames are processed sequentially; once a Frame is on a queue it can be processed in parallel with the frames being processed by the Pipeline. TODO: link to a more in-depth section about this.
+![sink queue](images/frame-progress-10.png)
+
+11. The TTS Frame Processor yields another Audio frame as the Transport transmits the first Audio frame.
+![parallel audio](images/frame-progress-11.png)
+
+12. As before, the LLM Assistant Message Aggregator immediately yields the Audio frame and the Pipeline places the Audio frame in the sink queue.
+![sink queue 2](images/frame-progress-12.png)
+
+13. The TTS Frame Processor has no more frames to yield. The LLM Frame Processor emits an LLM Response End Frame, which the Pipeline passes to the TTS Frame Processor.
+![response end](images/frame-progress-13.png)
+
+14. The TTS Frame Processor immediately yields the LLM Response End Frame, so the Pipeline passes it along to the LLM Assistant Message Aggregator. The LLM Assistant Message Aggregator updates the LLM Context with the full response from the LLM. TODO TODO: I realized I forgot that the TSS Frame Processor also yields the Text frames that the LLM emitted so that the LLM Assistant Message Aggregator could accumulate them, arrggh.
+![response end](images/frame-progress-14.png)
+
+15. The system is quiet, and waiting for the next message from the Transport.
+![response end](images/frame-progress-15.png)

+# Server Example
+
+Use this server app to quickly host a bot on the web:
+
+```
+flask --app daily-bot-manager.py --debug run
+```
+
+It's currently configured to serve example apps defined in the APPS constant in the server file:
+
+```
+chatbot
+patient-intake
+storybot
+translator
+```
+
+Once the server is started, you can create a bot instance by opening `http://127.0.0.1:5000/start/chatbot` in a browser, and the server will do the following:
+
+- Create a new, randomly-named Daily room with `DAILY_API_KEY` from your .env file or environment
+- Start an instance of `chatbot.py` and connect it to that room
+- 301 redirect your browser to the room
+
+### Options
+
+The server supports several options, which can be set in the body of a POST request, or as params in the URL of a GET request.
+
+- `room_url` (default: none): A room URL to join. If empty, the server will create a Daily room and return the URL in the response.
+  room_properties (none): A JSON object (URL encoded if included as a GET parameter) for overriding default room creation properties, as described here: https://docs.daily.co/reference/rest-api/rooms/create-room This will be ignored if a room_url is provided.
+- `token_properties` (none): A JSON object (URL encoded if included as a GET parameter) for overriding default token properties. By default, the server creates an owner token with an expiration time of one hour.
+- `duration` (7200 seconds, or two hours): Use this property to set a time limit for the bot, as well as an expiration time for the room (if the server is creating one). This will not add an expiration time to an existing room. Expiration times in `token_properties` or `room_properties` will also take precedence over this value. You can set this property to `0` to disable timeouts, but this isn't recommended.
+- `bot_args` (none): A string containing any additional command-line args to pass to the bot.
+- `wait_for_bot` (true): Whether to wait for the bot to successfully join the room before returning a response from the server. If true, the server will start the bot script, then poll the room for up to 5 seconds to confirm the bot has joined the room. If it doesn't, the server will stop the bot and return a 500 response. If set to `false`, the server will start the bot, but immediately return a 200 response. This can be useful if the server is creating rooms for you, and you need the room URL to join the user to the room.
+- `redirect` (true): Instead of returning a 200 for GET requests, the server will return a 301 redirect to the ROOM_URL. This is handy for testing by creating a bot with a GET request directly in the browser. POST requests will never return redirects. Set to `false` to get 200 responses with info in a JSON object even for GET requests.
