Measurement types, performance improvements, total time termination, parameterized model enhancements

Measurement types for non-time-series data

Cell measurements now support a measurement_type field with three values: time_series (the default), properties for key-value metadata such as checkpoint measurements, and file for arbitrary files such as images, PDFs, or numpy arrays. Each type has its own creation and retrieval flow, and list endpoints can filter by type.Find out more →

Performance improvements

Pipeline creation is now significantly faster: large job configurations are offloaded to object storage instead of being written inline to the database. The entire backend has also been migrated to an async Supabase client, improving throughput under concurrent load. Models, parameterized models, studies, and optimizations now use server-side pagination and filtering, eliminating the need to load entire collections into memory.

Total time termination condition

Protocol steps can now use total_time as a built-in termination condition, ending a step after a specified duration of total elapsed experiment time rather than just step time.Find out more →

Parameterized model improvements

The parameterized model detail view has been consolidated into a single page with tabs, replacing the previous multi-page layout. Models can now be downloaded as a zip archive containing the full configuration, and initial temperature is now parsed in design optimization objectives for temperature-dependent studies.Find out more →

You can now define custom derived quantities on models — such as electrode potentials or temperature in different units — as PyBaMM expressions stored in the model configuration. These custom variables are evaluated at simulation time and included in result data, making it easy to track application-specific metrics across design sweeps.Find out more →

BaSyTec battery cycler reader

The data processing library now supports BaSyTec CSV exports (CTS, X50 series).

Protocols section, job cancellation, parameterized durations, and optimization management

Dedicated Protocols section with parameterized input support

Studio now has a dedicated Protocols section where you can browse, edit, and clone saved experiment templates. Each protocol detail page shows the source YAML, a tabbed UCP/human-readable preview, and automatically detected input parameters with a generated parameters_schema. This makes it easy to build reusable, parameterized protocols and simulate them with different input values.Find out more →

Cancel running jobs from Studio

You can now cancel pipelines, optimizations, and simulations directly from the UI. Each detail page shows a cancel button for in-progress jobs, with optimistic status updates and automatic rollback if the cancellation fails. On the backend, cancelling a parent job cascades to all child jobs.

Protocol termination conditions and parameterized durations

Protocol simulations now support early termination based on variable conditions — useful for ending long protocols (e.g. multi-cycle Arbin tests) after a target number of cycles. Duration and termination end conditions also accept input['...'] references, enabling fully parameterized experiments such as eVTOL design optimization with variable cruise duration.Find out more →

Edit and delete optimizations

Optimization name and description are now editable from the detail page, and you can delete optimizations with a confirmation dialog. The experiment-step validation toggle is also exposed as a per-objective setting, letting you control whether each objective validates against experiment steps.
Improvements

  • Added optimization editing (name and description) and delete with permission checks.

Fixes
