Changelog
User-facing changes to self-hosted CosmicAC, by release.
New features, improvements, and fixes across self-hosted CosmicAC, with the newest release first. This changelog follows Keep a Changelog, and CosmicAC follows Semantic Versioning.
1.1.0 - 2026-09-02
Adds multi-node Managed Inference to both clients, an observability aggregator that CosmicAC now runs as part of the deployment, and job logs and metrics history in the web interface. One change is breaking. --api-key no longer accepts a value.
Platform
Web
Added
- Serve a Managed Inference model across two nodes with a 16-GPU count
- Read live and historical job logs, with time windows, search, and download
- View job metrics history as charts on a job page
- Run a health check on a Managed Inference endpoint from the Model Health page
- Set up job notifications, preview the payload, and review recent deliveries
- Connect CosmicAC to your Prometheus and Loki from an observability settings tab
Changed
- Location moved from Basics to the Hardware step, where it filters the GPU list
- Creating a job became a sequence of sections rather than one form
CLI
Added
- Serve a Managed Inference model across two nodes with a 16-GPU count
- See a reasoning model's thinking in
inference chat, and hide it with--disable-think - Set how much effort a reasoning model spends with
--reasoning-effort - Choose which lifecycle events a job reports with
--notify - Set a lookback window on
models healthcheckwith--period - See per-GPU resource specifications and replica node names in
jobs detail - Set a connection timeout on
jobs shellwith--timeout
Changed
cosmicac config setreplacesadmin config set, and needs no administrator credentials
Removed
- API keys as a command-line value, since
--api-keytakes no value
API
Added
- Send
chat_template_kwargsandreasoning_efforton a chat completion, and read the model's thinking in the response - Read and write observability settings
- Read job-scoped logs
- Read the per-replica GPU count and the replica count on job responses
Deployment
Added
- Run the observability aggregator as part of the deployment
- Pull root disk images to cluster nodes ahead of time with a DaemonSet
Removed
- The built-in log store, replaced by Loki
1.0.1 - 2026-07-17
Stabilisation and completion release following the initial version. Adds Parakeet speech-to-text serving and endpoint health monitoring, and fixes job-list reliability issues found in early operation.
Known limitation. In 1.0.1, CosmicAC includes no observability stack. Model Health metrics cover only Managed Inference endpoints, and CosmicAC provides no charting, alerting, or export. CosmicAC collects only job logs, and log collection is off by default. You install and operate any observability stack you need, such as Prometheus or Loki.
Platform
Web
Added
- Deploy and manage Parakeet speech-to-text endpoints through Managed Inference
- Track Managed Inference endpoint health, latency, and per-replica status from the Model Health page
- Replica overview shown separately from metrics statistics on job pages
- Diagnostic bundle collection when submitting feedback
Fixed
- Job list sorting failed with more than 10 jobs and the last job wasn't displayed
- Job statuses now update automatically without refreshing the page
- Failed replicas reported a generic "VMI failed" message instead of the real failure cause
CLI
Added
- Transcribe audio with a Parakeet endpoint
API
Added
- Transcribe audio to text through a Parakeet endpoint
Deployment
Added
- Installation guide for adding model master data to an instance
- Improved seeding of model master data for supported models
