These are the meanings used in the Studio. When a term has more than one meaning here, its entry names each use. The notes also flag other common meanings that could cause confusion; this is not a dictionary of every possible use.
studio bridge definition
Access path
A documented route by which someone may obtain or use a model, including its availability and eligibility conditions.
Example
A gated artifact download with stated eligibility.
Not an example
A model name mentioned in a news article.
Meaning and boundary
Access, licensing, deployment, and availability are separate questions. A visible page is not automatically a usable or permitted path.
A term whose meaning depends on context: in orchestration, software that selects or carries out actions; in simulation, an entity following local rules; in provenance, a person, organization, or software entity responsible for activity.
Example
A tool-using workflow controller, a NetLogo simulated actor, or a PROV software agent when the context names that role.
Not an example
Calling every language model an autonomous agent.
Meaning and boundary
The Studio uses all three senses. A model alone is not an orchestration agent, a simulated agent need not use AI, and a PROV agent denotes responsibility rather than autonomy.
An identifiable computational design that maps inputs to outputs for a designed contribution. The Studio separates it from the surrounding application, runtime, and access path.
Example
An encoder designed to produce text representations.
Not an example
An entire retrieval application with its index, permissions, and interface.
Meaning and boundary
Model can also mean a conceptual, data, statistical, or simulation model. In the Computational Model Studio it means a computational design; a model release is a specific versioned identity.
A maintained set of concepts or terms with chosen labels and, where useful, stated relationships for consistent description.
Example
Preferred and alternative labels for document types.
Not an example
Whatever tags users happen to type without curation.
Meaning and boundary
A controlled vocabulary can organize labels without the formal logical commitments of an OWL ontology. Some uses of taxonomy name a hierarchical subset of this work.
A numeric representation of an input that can support comparison or downstream computation.
Example
Text encoded as a vector for a retrieval index.
Not an example
The document text itself.
Meaning and boundary
An embedding is a representation, not an explanation of meaning. The same word is also used for embedding content in a page or program; that is a different sense.
A structured assessment of a system, model, or process against stated criteria using evidence appropriate to the intended use.
Example
Test retrieval relevance on a specified document set.
Not an example
Treat a vendor claim as an independent test result.
Meaning and boundary
The evaluated object matters: a model benchmark does not evaluate an entire application, and a source review does not test product performance. A governance review may use different criteria from a task test.
Further training that adapts an existing model by updating some or all trainable parameters for a task or domain.
Example
Train a low-rank adapter for a base model.
Not an example
Change only the text of a runtime prompt.
Meaning and boundary
Parameter-efficient fine-tuning updates a small subset or adapters; full fine-tuning updates more weights. Prompting a model without changing parameters is a different operation.
A structured set of concepts or guidance for organizing decisions or practices in a domain.
Example
A published AI risk management framework.
Not an example
A runtime library used to call a model.
Meaning and boundary
Framework can also mean a software library; Studio framework records refer to published guidance. Using a framework is not evidence of compliance or effectiveness.
The policies, roles, decisions, and oversight used to direct and account for how an AI system is developed and used.
Example
Set approval roles and monitoring responsibilities for a deployed AI workflow.
Not an example
Assume one prompt filter establishes organizational oversight.
Meaning and boundary
Governance is broader than a technical guardrail or one compliance document. The Studio also uses the word for cross-area responsibilities, not a standalone tool category.
Identifiable software or a service that can put an approach to work in a particular setting.
Example
A named vector search engine.
Not an example
The general idea of similarity search.
Meaning and boundary
In general usage, implementation can mean the act of building a system. Studio implementation records name software or services; model releases have separate records.
The kind of information a model accepts or returns, such as text, image, audio, video, structured symbols, or numeric data.
Example
Audio input and text output for speech transcription.
Not an example
Calling every model that processes video a video generator.
Meaning and boundary
Input and output modalities are recorded separately. Output modality says what form is returned; it does not establish the task, such as generating video versus tracking masks through video.
A downloadable or otherwise distributable file set associated with a model release or variant, such as weights or a packaged runtime form.
Example
A publisher-hosted checkpoint for local inference.
Not an example
A hosted API endpoint without distributable model files.
Meaning and boundary
Artifact elsewhere can mean any by-product. Here it is a model distribution object; its availability and terms do not automatically permit every deployment.
A named, citable publication of a computational model at a particular version or release identity.
Example
A publisher's named 2025 model release with a model card.
Not an example
A generic family name with no release identity.
Meaning and boundary
A release is the model identity being described here. A downloadable file, hosted endpoint, and later variant are separately represented even if marketing names overlap.
A documented variation of a model release with a meaningful difference in configuration, training, specialization, or packaging.
Example
An instruction-tuned variant linked to its base release.
Not an example
A second mirror URL for the same file.
Meaning and boundary
Variant may describe a distinct model configuration; a file format or quantized copy can instead be an artifact. The Studio follows what the source actually distinguishes.
A structured description of a domain's concepts and relationships; formal ontologies can support machine-interpretable meaning and inference.
Example
OWL classes and properties describing a domain.
Not an example
An unlabeled list of keywords.
Meaning and boundary
Ontology can be used broadly for a conceptual map. In the Studio's OWL and entailment examples it means a formal representation with defined semantics, not just a list of tags.
Information about the origin, derivation, and history of an entity or result.
Example
A document records its source and transformation.
Not an example
An uncited assertion of accuracy.
Meaning and boundary
Lineage is often used for derivation chains; provenance can include wider context such as agents and activities. A trace does not establish correctness by itself.
