What you will find in our AI news

Techlära covers artificial intelligence for people who want to understand what is actually happening without first having to learn the industry jargon. We follow the large language models — ChatGPT and the GPT series from OpenAI, Claude from Anthropic, Google Gemini, DeepSeek and the open models — and explain what each release means in practice for anyone using these tools at work.

Every article starts from the same question: what changes for the user? A new model, a larger context window or new pricing only matters once it changes how you can solve a task. That is why we mix news coverage with guides, comparisons and concrete examples from our own work as AI consultants.

Topics we keep returning to

• Language models and how they work — from the basics of what an LLM is to context windows, tokens and reasoning models.
• Comparisons — we test the chatbots against each other on real tasks instead of trusting benchmarks.
• AI agents and automation — when AI stops answering and starts doing: tools, workflows and guardrails.
• Practical guides — prompting, Custom GPTs, transcription, image generation and other things you can start using the same day.
• AI for business — how companies actually get value from the technology, and where it usually goes wrong.

How we write

The articles are written by Johannes Olsson, founder of Techlära, who works daily on building AI solutions for companies. We date and update the texts as the field moves — and this field moves often. An "Updated" date means the content has been reviewed against how things stand now, not just when it was first published.
