Practical AI glossary — terms and common confusions
- Model
- A learned component used to produce a result.
A drafting model is one part of a letter app; it is not the whole app.
- Application
- The software experience around components and services.
A letter app adds accounts, storage, and a Send button.
- Prompt
- Instructions and input supplied for a task.
“Summarize this notice in two bullets” specifies a task and shape, not a truth guarantee.
- Token
- A unit a model processes; it need not be a whole word.
A tokenizer can split a name into pieces; count using the actual system.
- Context
- Information available for the current request.
An earlier attachment may be absent even when its filename is visible.
- Training
- Adjusting a model using examples.
A training log differs from a conversation correction.
- Inference
- Using a trained model to produce a result.
Drafting another sentence does not by itself prove retraining.
- Retrieval
- Selecting material to supply to a task.
A retrieved notice still needs a relevance and date check.
- Embedding
- A numerical representation used to compare or organize items.
A similar search match is a candidate, not proof of the same meaning.
- Tool
- A function an application can call.
A calendar lookup can be read-only; finding an event is different from creating one.
- Agent
- Software that can choose and carry out steps toward a goal.
An agent still needs bounded permissions and checked action receipts.
- Hallucination
- Plausible generated content that is unsupported or false.
An invented opening time needs evidence or removal, even when phrased confidently.
- Evaluation
- Checking results against stated criteria.
Twenty checked examples establish a bounded result, not universal reliability.
- Multimodal
- Working with more than one kind of input or output.
A photo plus text does not prove every small label in the photo was read correctly.
Outcome
Justify acceptance or correction of an interpretation involving permission, negation, and ambiguous ownership.
Why it matters
Use exact wording and context to decide whether an AI interpretation preserves the original meaning. A correct response deserves acceptance, not a manufactured correction.
Concept
A prompt is an instruction in a particular context. The same words can support more than one interpretation when a person, date, or condition is missing. An assistant can produce fluent wording without resolving that ambiguity correctly.
Meaning is not a count of matching words. “Not all requests were approved” does not mean “No requests were approved.” “May” allows a possibility; “must” imposes a requirement in the fictional instructions used here. When a source leaves something open, ask a targeted question instead of manufacturing certainty.
Before revising an answer, check whether it already preserves the source. A valid paraphrase may use different words. Adding an unnecessary condition can be as misleading as removing one.
Worked example
A fictional booking note says: “The room is reserved for Tuesday, subject to the caretaker confirming access.” A draft says: “Tuesday access is confirmed.” The draft removes a condition. A supported repair is: “The Tuesday reservation depends on the caretaker confirming access.” The evidence is the phrase “subject to”; it changes whether the reader may rely on entry. A draft that already includes that condition should be accepted without an edit.
The condition changes what the note establishes
The room is reserved for Tuesday, subject to the caretaker confirming access.
The underlined words keep an access condition attached to the reservation. This note alone does not establish that access has been confirmed.
Condition preserved
Draft- The Tuesday reservation depends on the caretaker confirming access.
Accept this supported wording unless another requirement is unmet.
Condition dropped
Draft- Tuesday access is confirmed.
Revise this claim: it asserts confirmation that the note does not supply.
Practice and transfer
Use only the supplied fictional facts. Choose accept, revise, or evidence insufficient, then justify your decision. The next cases may be correct or flawed.
Assess the response
Use Accept when all material claims are supported. Use Revise when a supplied fact or requirement is contradicted. Use Evidence is insufficient when a key fact cannot be established either way. If a response contains both an unknown and a direct contradiction, choose Revise and explain both problems. Conflicting claims with no established authority remain insufficient; a claim does not become a governing fact merely because a source asserts it.
Some responses are fully supported. Others need correction or more evidence. Judge each on its sources; do not edit a correct answer just to change it.
Your written notes stay in this page and disappear when you leave. Only a self-reviewed completion can be saved to your learning account. These practice checks do not establish independent proficiency.
Practice
Case 1
You are checking a fictional team update. The task is to report whether approval was universal, without adding a count.
Source packet
- Source 1
- Review note: Not all eight requests were approved. The note gives no count of approved requests.
- Source 2
- The next team meeting is in Room 4.
Response to assess
The note does not support saying that every request was approved. It does not establish an exact approved count.
Practice
Case 2
Consider a fictional reminder. Your job is to preserve the stated distinction between what is required and what is optional.
Source packet
- Source 1
- Workshop note: Facilitators must bring the printed attendance sheet. Participants may bring a notebook.
- Source 2
- The workshop begins at 10 a.m.
Response to assess
Everyone must bring a printed attendance sheet and a notebook to the workshop.
Fresh transfer
Case 3
Prepare a one-sentence handoff from a fictional message. No other conversation is available, and the task requires naming the draft owner only if established.
Source packet
- Source 1
- Alex told Jordan their draft was ready for review.
- Source 2
- Alex and Jordan both have drafts in progress.
Response to assess
Jordan’s draft is ready for review.
Fresh transfer
Case 4
Consider the entire proposed instruction against a fictional scheduling update. The task is to retain the update’s date and exception.
Source packet
- Source 1
- Final scheduling update: Submit the outline by 12 October unless your team has a written extension.
- Source 2
- Earlier draft: Submit the outline by 8 October. This draft was replaced by the final update.
Response to assess
The outline is due by 12 October. Teams with a written extension are excepted.

Summary and next step
Take the checklist to a fresh task. Keep supported wording, repair only what the evidence warrants, and leave unresolved details explicit. Saving completion records self-review; independent learning needs a facilitator to review your explanation and transfer case.
