AI-driven software development is all the rage in 2026. If you look online, you'll find a endless stream of proclaimations such as "software development is dead", "anyone can code now" and "if you're not doing AI-driven software development you're a dinosaur". The same philosophy is now expanding to office-based work in general.
Astute developers and business professionals have already taken a look at this new paradigm and have started making their minds up on how it can help them. There is no right answer, plenty of people haven't adapted and they're still happily working. TxtAI has a simple yet robust framework for agents and local AI-driven development.
The next release will add Agent Tools which is a set of tools to connect agents with the operating system. Tools such as reading, writing and finding files add an extremely simple but effective way to work with data.
Let's get started!
Install dependencies
Install txtai and all dependencies.
%%capture
!pip install git+https://github.com/neuml/txtai#egg=txtai[agent]
# Get working files
!git clone https://github.com/neuml/txtai
!wget -N https://github.com/neuml/txtai/releases/download/v6.2.0/tests.tar.gz
!mkdir files
!tar -xvzf tests.tar.gz --strip-components=1 -C files
Create the Agent
The first step is creating a TxtAI agent. The agent is an LLM with access to a set of tools. In this case, we'll use a Qwen 3 Coder LLM along with the default toolkit. This toolkit has the following tools.
| Tool | Description |
|---|---|
| bash | Runs a shell command through subprocess |
| edit | Edits a file in place and returns a diff |
| glob | Finds matching file patterns in a directory |
| grep | Finds matching file content in a directory |
| python | Runs a Python action |
| read | Reads file or url content, supports text extraction |
| todowrite | Generates a task list to organize complex tasks |
| websearch | Runs a websearch using the built-in websearch tool |
| webview | Extracts content from a web page. Alias for read tool |
| write | Writes content to file |
The default toolkit adds the ability to interact with the local file system and OS.
from txtai import Agent
agent = Agent(llm={
"path": "unsloth/Qwen3-Coder-30B-A3B-Instruct-GGUF/Qwen3-Coder-30B-A3B-Instruct-Q3_K_M.gguf",
"n_ctx": 30000
}, tools=["defaults"])
Search a directory for content
Of course we can build a search index for files and then an interace to search that index and even rephrase the results with an LLM. This is the basic idea behind Retrieval Augmented Generation (RAG).
But as modern coding tools are now showing, just scanning a file system and letting the LLM parse through the content is another compelling option. This example does just that! It looks in a directory to answer a question.

As we can see, the Agent stepped through the files and found the answer. One of the most powerful tools in the txtai agent toolkit is the read tool. It doesn't just simply read raw files, it has the ability to extract text from common document formats such as DOC, XLS, PDF. As you see above, the agent looked through text files, documents and PDFs as if they were all text files.

## Use Cases
The following sections introduce common txtai use cases. A comprehensive set of over 70 |example notebooks and
applications](https://neuml.github.io/txtai/examples) are also available.
### Semantic Search
Build semantic/similarity/vector/neural search applications.
Traditional search systems use keywords to find data. Semantic search has an understanding of natural language and
identifies results that have the same meaning, not necessarily the same keywords.
Get started with the following examples.
|Notebook|Description||
|---|---|---|
||Introducing txtai](https://github.com/neuml/txtai/blob/master/examples/01_Introducing_txtai.ipynb) |Overview of
the functionality provided by txtai||
||Similarity search with

|Explore topics, data connectivity and run network analysis||
### LLM Orchestration
Autonomous agents, retrieval augmented generation (RAG), chat with your data, pipelines and workflows that
interface with large language models (LLMs).

#### Agents
Agents connect embeddings, pipelines, workflows and other agents together to autonomously solve complex problems.
txtai agents are built on top of the |smolagents](https://github.com/huggingface/smolagents) framework. This
supports all LLMs txtai supports (Hugging Face, llama.cpp, OpenAI / Claude / AWS Bedrock via LiteLLM). Agent
prompting with |agents.md](https://github.com/agentsmd/agents.md) and
|skill.md](https://agentskills.io/specification) are also supported.

#### Retrieval augmented generation
Retrieval augmented generation (RAG) reduces the risk of LLM hallucinations by constraining the output with a
knowledge base as context. RAG is commonly used to "chat with your data".

### Language Model Workflows
Language model workflows, also known as semantic workflows, connect language models together to build intelligent
applications.
While LLMs are powerful, there are plenty of smaller, more specialized models that work better and faster for
specific tasks. This includes models for extractive question-answering, automatic summarization, text-to-speech,
transcription and translation.

Observations: **Installation - txtai** *txtai is an all-in-one open-source AI framework for semantic search, LLM orchestration and language model workflows* # Installation The easiest way to install is via pip and PyPI ```shell pip install txtai ``` Python 3.10+ is supported. Using a Python |virtual environment](https://docs.python.org/3/library/venv.html) is recommended. ## Optional dependencies txtai has the following optional dependencies that can be installed as extras. The patterns below are supported in setup.py install_requires sections. *Note: Extras are provided for convenience. Alternatively, individual packages can be installed to limit dependencies.* ### All Install all dependencies. ```shell pip install txtai|all] ``` ### ANN Additional ANN backends. ```shell pip install txtai|ann] ``` ### API Serve txtai via a web API. ```shell pip install txtai|api] ``` ### Cloud Interface with cloud compute. ```shell pip install txtai|cloud] ``` ### Console Command line index query console. ```shell pip install txtai|console] ``` ### Database Additional content storage options. ```shell pip install txtai|database] ``` ### Graph Topic modeling, data connectivity and network analysis. ```shell pip install txtai|graph] ``` ### Model Additional non-standard models. ```shell pip install txtai|model] ``` ### Pipeline All pipelines - default install comes with most common pipelines. ```shell pip install txtai|pipeline] ``` More granular extras are available for pipeline categories: pipeline-audio, pipeline-data, pipeline-image, pipeline-llm, pipeline-text, and pipeline-train. ### Scoring Additional scoring methods. ```shell pip install txtai|scoring] ``` ### Vectors Additional vector methods. ```shell pip install txtai|vectors] ``` ### Workflow All workflow tasks - default install comes with most common workflow tasks. ```shell pip install txtai|workflow] ``` ### Combining dependencies Multiple dependencies can be specified at the same time. ```shell pip install txtai|pipeline,workflow] ``` ## Environment specific prerequisites Additional environment specific prerequisites are below. ### Linux The AudioStream and Microphone pipelines require the |PortAudio](https://python-sounddevice.readthedocs.io/en/0.5.0/installation.html) system library. The Transcription pipeline requires the |SoundFile](https://github.com/bastibe/python-soundfile#installation) system library. ### macOS Older versions of Faiss have a runtime dependency on libomp for macOS. Run brew install libomp in this case. The AudioStream and Microphone pipelines require the |PortAudio](https://python-sounddevice.readthedocs.io/en/0.5.0/installation.html) system library. Run brew install portaudio. ### Windows Optional dependencies require |C++ Build Tools](https://visualstudio.microsoft.com/visual-cpp-build-tools/) The |txtai build workflow](https://github.com/neuml/txtai/blob/master/.github/workflows/build.yml) occasionally has work arounds for other known but temporary dependency issues. The |FAQ](../faq) also has a list of common problems, including common installation issues. ## CPU-only The default install adds PyTorch with GPU support. There are a number of dependencies that come with that. When running in a CPU-only environment or using Embeddings/LLM models without PyTorch (i.e. llama.cpp or API services), the CPU-only PyTorch package can be installed with txtai as follows. ```shell pip install txtai torch==|version]+cpu \ -f https://download.pytorch.org/whl/torch ``` Where |version] is the version of PyTorch (such as 2.4.1). The |txtai-cpu](https://hub.docker.com/r/neuml/txtai-cpu) image on Docker Hub uses this method to reduce the image size. ## Install from source txtai can also be installed directly from GitHub to access the latest, unreleased features. ```shell pip install git+https://github.com/neuml/txtai ``` Extras can be installed from GitHub by adding #egg=txtai|<name-of-extra>] to the end of the above URL. ## Conda A |community-supported txtai package](https://anaconda.org/conda-forge/txtai) is available via conda-forge. ```shell conda install -c conda-forge txtai ``` ## Run with containers Docker images are available for txtai. |See this section](../cloud) for more information on container-based installs.

Observations: BERT: Pre-training of Deep Bidirectional Transformers for
Language Understanding
Jacob Devlin Ming-Wei Chang Kenton Lee Kristina Toutanova
Google AI Language
{jacobdevlin,mingweichang,kentonl,kristout}@google.com
Abstract
We introduce a new language representa-
tion model called BERT, which stands for
Bidirectional Encoder Representations from
Transformers. Unlike recent language repre-
sentation models (Peters et al., 2018a; Rad-
ford et al., 2018), BERT is designed to pre-
train deep bidirectional representations from
unlabeled text by jointly conditioning on both
left and right context in all layers. As a re-
sult, the pre-trained BERT model can be fine-
tuned with just one additional output layer
to create state-of-the-art models for a wide
range of tasks, such as question answering and
language inference, without substantial task-
specific architecture modifications.

│ Bidirectional Transformers for Language Understanding\n\nSummary:\n\nBERT (Bidirectional Encoder │
│ Representations from Transformers) is a language representation model introduced by Google AI Language │
│ researchers. Unlike previous approaches that used unidirectional language models, BERT uses a bidirectional │
│ approach to pre-train deep representations from unlabeled text.\n\nKey innovations of BERT include:\n\n1. │
│ Bidirectional Pre-training: Unlike previous models like OpenAI GPT that use left-to-right language models, BERT │
│ uses a masked language model (MLM) pre-training objective that allows it to condition on both left and right │
│ context in all layers.\n\n2. Two Pre-training Tasks: BERT uses two unsupervised pre-training tasks - Masked │
│ Language Model (predicting masked tokens) and Next Sentence Prediction (understanding relationships between │
│ sentences).\n\n3. Unified Architecture: BERT uses the same architecture for both pre-training and fine-tuning, │
│ with minimal differences between the two stages.\n\n4. Fine-tuning Approach: BERT can be fine-tuned with just │
│ one additional output layer for various downstream tasks, without substantial task-specific architecture │
│ modifications.\n\nPerformance Improvements:\n\nBERT achieved state-of-the-art results on 11 natural language │
│ processing tasks, including:\n- GLUE score of 80.5% (7.7% absolute improvement)\n- MultiNLI accuracy of 86.7% │
│ (4.6% absolute improvement)\n- SQuAD v1.1 question answering Test F1 of 93.2 (1.5 point absolute │
│ improvement)\n- SQuAD v2.0 Test F1 of 83.1 (5.1 point absolute improvement)\n\nThe model comes in two sizes: │
│ BERTBASE (L=12, H=768, A=12) and BERTLARGE (L=24, H=1024, A=16) with 110M and 340M parameters │
│ respectively.\n\nBERT demonstrated that bidirectional pre-training is crucial for language representations and │
│ that pre-trained representations significantly reduce the need for heavily-engineered task-specific │
│ architectures.'} │

Building code with AI
Ok, now let's do some AI-driven software development. We're going to build a Python program that generates the song "Twinkle Twinkle Little Star" and plays it using TxtAI's audio stream pipeline.
agent((
"Play twinkle twinkle little star song using simple notes translated to frequencies and the txtai audio stream pipeline. "
"The txtai code is available in txtai/src"

'I\'ve successfully created a solution that demonstrates how to play "Twinkle Twinkle Little Star" using simple notes translated to frequencies and the txtai audio stream pipeline.\n\n## Solution Overview\n\nThe implementation consists of:\n\n1. **Frequency-based note generation**: Converting musical notes to their corresponding frequencies\n2. **Audio stream pipeline**: Using txtai\'s `AudioStream` class to handle audio playback\n3. **Melody composition**: Translating the Twinkle Twinkle Little Star melody into playable notes\n\n## Key Components\n\n### Note Frequencies\nThe implementation uses standard musical note frequencies:\n- C4 = 261.63 Hz\n- D4 = 293.66 Hz\n- E4 = 329.63 Hz\n- F4 = 349.23 Hz\n- G4 = 392.00 Hz\n- A4 = 440.00 Hz\n- B4 = 493.88 Hz\n- C5 = 523.25 Hz\n\n### Melody Structure\nThe Twinkle Twinkle Little Star melody is represented as a sequence of note-duration pairs:\n
\nC4(0.5s), C4(0.5s), G4(0.5s), G4(0.5s), A4(0.5s), A4(0.5s), G4(1.0s),\nF4(0.5s), F4(0.5s), E4(0.5s), E4(0.5s), D4(0.5s), D4(0.5s), C4(1.0s)\n
\n\n## Implementation Details\n\nThe solution creates a sine wave for each note using the formula:\n
\nwave = sin(2π × frequency × time)\n
\n\nThen converts the wave to 16-bit integers for compatibility with the audio stream pipeline.\n\n## How to Run\n\n1. Ensure you have the required dependencies installed:\n
bash\n pip install sounddevice scipy numpy\n
\n\n2. Run the script:\n
bash\n python twinkle_twinkle_final.py\n
\n\nThe script will:\n- Create an audio stream\n- Generate and play each note in the melody\n- Wait for all notes to finish playing\n- Print status messages during execution\n\n## Technical Approach\n\nThe implementation leverages txtai\'s AudioStream pipeline which:\n- Uses threading to handle audio playback\n- Supports sample rate conversion\n- Provides blocking playback for sequential note playing\n- Handles audio device access for local playback\n\nThis approach demonstrates the complete integration of musical note generation with txtai\'s audio streaming capabilities, following the structure and patterns found in the txtai/src directory.\n\nNote: While the code is properly structured and should work in environments with proper audio support, the execution environment may not have audio output capabilities, which is why no audible sound was produced during testing.'
Depending on the permissions given to the bash tool, some steps will be no-op. For example, the default settings don't allow running python or curl. So they're just skipped over.
If this worked as expected, you should have a Python file with code similar to what's below

Observations: I have successfully added a new Pattern pipeline to txtai that replaces input text with a new
pattern. Here's what I did:
1. Created a new file `txtai/src/python/txtai/pipeline/text/pattern.py` with a Pattern class that inherits from
Pipeline base class
2. Implemented the `__call__` method to use Python's `re.sub()` for pattern replacement
3. Added a `batch` method to process multiple texts at once
4. Updated `txtai/src/python/txtai/pipeline/text/__init__.py` to export the new Pattern class
The new pipeline can be used like this:
```python
from txtai.pipeline.text import Pattern
# Create a pattern replacement pipeline
pipeline = Pattern(r"\d+", "|NUMBER]")
# Process text
result = pipeline("I have 5 cats and 3 dogs")
# Returns: "I have |NUMBER] cats and |NUMBER] dogs"
# Process batch
batch_result = pipeline.batch(|"I have 5 cats", "She has 2 dogs"])
# Returns: |"I have |NUMBER] cats", "She has |NUMBER] dogs"]
```
Final answer: I have successfully added a new Pattern pipeline to txtai that replaces input text with a new pattern. Here's what I did: 1. Created a new file `txtai/src/python/txtai/pipeline/text/pattern.py` with a Pattern class that inherits from Pipeline base class 2. Implemented the `__call__` method to use Python's `re.sub()` for pattern replacement 3. Added a `batch` method to process multiple texts at once 4. Updated `txtai/src/python/txtai/pipeline/text/__init__.py` to export the new Pattern class The new pipeline can be used like this: ```python from txtai.pipeline.text import Pattern # Create a pattern replacement pipeline pipeline = Pattern(r"\d+", "[NUMBER]") # Process text result = pipeline("I have 5 cats and 3 dogs") # Returns: "I have [NUMBER] cats and [NUMBER] dogs" # Process batch batch_result = pipeline.batch(["I have 5 cats", "She has 2 dogs"]) # Returns: ["I have [NUMBER] cats", "She has [NUMBER] dogs"] ```

Pretty solid! Notice how the agent was able to figure out how TxtAI pipelines work, add a new pipeline and make the appropriate edits.
A fully working TxtAI pipeline ready to submit as a PR.
Wrapping up
This example demonstrated the new agent tools capability coming to TxtAI. Keep in mind these tools can be combined with the existing toolset that enabled reading content from Embeddings databases. These embeddings databases often store business-specific domain knowledge and content.
A compelling open and local-focused AI development platform is within reach!
