    Private UKP models and cluster experiments

    • NewYou can now run co-construction sessions on UKP's self-hosted Ollama models, so your documents stay on TU Darmstadt infrastructure. Pick one from the UKP group in the model selector; it needs the UKP VPN. Learn more
    • NewResearchHAI-Co² researchers can now run batch experiments against private UKP-cluster models through SLURM, with resumable runs and optional trace capture. This research infrastructure is not available in the Studio.
    • ChangedClaude Sonnet 5 is now the default model for new conversations and appears at the top of the Anthropic group in the model selector. The DeepSeek and Alibaba models are no longer offered. Conversations you already started still open, and new turns fall back to your default model.
    • NewThe Studio now shows release notes in this panel and from the bell in the top bar. It also shows its version in the footer and account menu, so include it when you report a problem.
    • FixedFixed a problem where a turn could keep running without ever answering, and still be recorded as finished. When the model cannot use one of its tools correctly, the turn now stops with a clear error instead, so you can try again or switch to another model.
