1.26 · Projects, Gemini 4 Argon, GPT-6.1 Sol, Kolibri 1, and Claude Haiku 5.5

With release 1.26, shared initiatives get a dedicated place in MAIA. Decisions and background knowledge remain available across individual conversations and handovers. The team works from the same knowledge base, while personal chats stay private.

Projects

Projects bring files and project knowledge together in one shared place.

What's new:

• New project chats start with the project's files preselected as sources.
• The shared project context records decisions, requirements, and background knowledge that MAIA considers in every project chat.
• Multiple projects can be selected together as sources for research.
• Projects can be handed over and archived. Archiving preserves files and project knowledge.

New models

The model selection includes the following models:

• Gemini 4 Argon
• GPT-6.1 Sol
• Kolibri 1
• Claude Haiku 5.5

Gemini 4 Argon, GPT-6.1 Sol, and Claude Haiku 5.5 run in the EU as usual, in line with data protection requirements. Kolibri 1 is an open-weight model hosted in Germany in line with data protection requirements.

Aleph Alpha developed Kolibri in Germany and trained it on infrastructure in Germany and Finland. It has a particular focus on German-language texts and the domain context of businesses and public administration. Publicly available model weights and development under European control support the goal of digital sovereignty. Details from Aleph Alpha.

Note: Apertus 70B, Claude Sonnet 5, and Claude Opus 5 are retired. Workflow steps using the previous Claude models switch to their respective 5.5 successors.

Other improvements

The release also includes minor bug fixes.

Projects and all new models are available to all users in all licensed workspaces.
