Has the open-source gap closed?

Elena Daehnhardt · 24 Apr, 2026

OpenAI ended the week by releasing GPT-5.5 — codenamed Spud — retaking the top spot across 14 benchmarks and positioning itself explicitly as an agent runtime rather than a chat model. Two Chinese labs shipped frontier-quality models on the same day: Alibaba's Qwen 3.6-Max-Preview closed its weights for the first time, and Moonshot's open-source Kimi K2.6 reached #4 on the global intelligence index, level with Western frontier labs. OpenAI's gpt-image-2 introduced reasoning into image generation. Google confirmed Gemini will power the next Siri. Amazon committed another $25 billion to Anthropic. And the Stanford AI Index documented a field accelerating faster than every institution surrounding it. Nine signals. A week that moved the map. Read more...

Agents, Cyber Models, and the Safety Stack Tightening Up

Elena Daehnhardt · 17 Apr, 2026

This week's clearest AI signal was not a giant new general model. It was the rapid convergence of stronger agent tooling, more cyber-capable systems, and tighter safety controls. Anthropic shipped Claude Opus 4.7 with new cyber safeguards. OpenAI expanded trusted cyber access, upgraded its Agents SDK, and pushed Codex deeper into real developer workflows. Microsoft launched a cheaper production-grade image model. Meanwhile, Anthropic's Mythos triggered a real regulatory response across central banks and governments. Read more...

Image classification is a complex task. However, we can approach the problem while reusing state-of-the-art pre-trained models. Using previously learned patterns from other models is named "Transfer Learning." This way, we can efficiently apply well-tested models, potentially leading to excellent performance. Read more...

TensorFlow: Multiclass Classification Model

Elena Daehnhardt · 6 Feb, 2022

In Machine Learning, the classification problem is categorising input data into different classes. For instance, we can categorise email messages into two groups, spam or not spam. In this case, we have two classes, we talk about binary classification. When we have more than two classes, we talk about multiclass classification. In this post, I am going to address the latest multiclass classification, on the example of categorising clothing items into clothing types. Read more...

Feature preprocessing

Elena Daehnhardt · 29 Jan, 2022

Machine Learning algorithms often require that data is in a specific type. For instance, we can use only numerical data. In other cases, ML algorithms would perform better or converge faster when we preprocess data before training the model. Since we do this step before training the model, we call it preprocessing.

TensorFlow: Regression Model

Elena Daehnhardt · 21 Jan, 2022

I have described regression modeling in TensorFlow. We have predicted a numerical value and adjusted hyperparameters to better model performance with a simple neural network. We generated a dataset, demonstrated a simple data split into training and testing sets, visualised our data and the created neural network, evaluated our model using a testing dataset. Read more...

TensorFlow: Global and Operation-level Seeds

Elena Daehnhardt · 15 Jan, 2022

In training Machine Learning models, we want to avoid any ordering biases in the data. In some cases, such as in Cross-Validation experiments, it is essential to mix data and ensure that the order of data is the same between different runs or system restarts. We can use operation-level and global seeds to achieve the reproducibility of results. Read more...

Tensors in TensorFlow

Elena Daehnhardt · 13 Jan, 2022

TensorFlow is a free OS library for machine learning created by Google Brain. Tensorflow has excellent functionality for building deep neural networks. I have chosen TensorFlow because it is pretty robust, efficient, and can be used with Python. In this post, I am going to write about how we can create tensors, shuffle them, index them, get information about tensors with simple examples. Read more...

TensorFlow on M1

Elena Daehnhardt · 5 Jan, 2022

TensorFlow is a free OS library for machine learning created by Google Brain. Tensorflow has excellent functionality for building deep neural networks. I have chosen TensorFlow because it is pretty robust, efficient, and can be used with Python. Since I like Jupyter Notebooks and Conda, they were also installed on my system. Next, I am going through simple steps to install TensorFlow and the packages above on M1 macOS Monterey. Read more...

Artificial Neural Networks

Elena Daehnhardt · 17 Dec, 2021

Artificial neural networks (ANNs) are the cornerstone of Deep Learning algorithms. The name and the architecture are adopted from the human brain's neural network. ANNs are designed to simulate human reasoning based on how neurons communicate. ANNs contain a set of artificial neurons connected. Read more...

Minimalism in Coding and Design

Elena Daehnhardt · 16 Dec, 2021

Nowadays, technology advances so rapidly that I sometimes feel like running after leaving the train. More technical knowledge is needed every day. Yesterday, it was GIT and workflows, and today it is Docker. What is next? Read more...

Deep Learning with DataCamp and Twitter

Elena Daehnhardt · 13 Dec, 2021

While having some machine learning experience of working with Scikit Learn, I was always interested in Deep Learning. The plan is to learn basic concepts and apply algorithms to a real-life situation, which I have always liked. Read more...

GIT in 10 minutes

Elena Daehnhardt · 4 Dec, 2021

Version control systems are handy to keep track of file versions. This is useful for tracking your code, scripts and text information. Currently, GIT is one of the best open-source and cross-platform version control solutions. It enables distributed repository management; it works fast over HTTP and ssh protocols. GIT is relatively easy to use, with command-line utility or Graphical User Interface. Read more...
