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
Check a summary for accurate scope, material omissions, and unsupported additions.
Why it matters
Compress a document while retaining the conditions a reader needs for the task.
Concept
A summary selects and compresses. Its success depends on purpose: an action briefing needs deadlines and responsibilities, while a background overview may emphasize context. Identify material facts before drafting and trace each summary claim back to its passage.
Omission is not always an error; compression requires leaving things out. The test is whether the omitted detail changes the reader’s understanding or ability to act under the brief. Preserve exceptions, uncertainty, and decision status. Do not promote a proposal into an approved decision or add a cause because it makes the account smoother.
Worked example
Cedar’s note says the morning session is proposed, subject to Hall C confirmation. A one-line summary calling it confirmed drops a material condition. “Morning session proposed; Hall C confirmation pending” compresses the note faithfully. The note’s decorative header color is irrelevant to a scheduling handoff.
Cedar continuity note: these lessons use separate snapshots—room selection, booking pending, booking confirmed, and later attendance review. Survey responses are preferences, not attendance. Each supplied packet identifies the facts for its own task; do not import a later snapshot into an earlier decision.
Shorten the wording, keep the decision status
Source meaning: morning session proposed, subject to Hall C confirmation.
The condition is material to a scheduling handoff. This is the pending snapshot, not a later confirmed booking.
Faithful compression
“Morning session proposed; Hall C confirmation pending”
Preserves proposed status and the pending condition
The shorter wording still tells the reader what remains unresolved.
Unsupported promotion
Summary claim: morning session confirmed
Drops the condition and changes proposed into confirmed
A shorter sentence is not faithful if it changes what the reader can act on.
Before you check
Make a claim-to-passage list for a short summary. Circle any condition whose removal would change what a reader can safely do.
Practice and fresh transfer
The packets below are fictional and contain the facts needed for these cases. External references are optional background. Judge each response independently: it may be supported, contradicted, or unresolved. Select the passages needed to justify your judgment and write why the distinction matters before revealing feedback.
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
Consider the proposed response for this fictional Cedar work task. Use the supplied packet and stated requirements.
Source packet
- Source 1
- Coordinator note: A morning workshop is proposed, pending confirmation of Hall C.
- Source 2
- Brief: Summarize the scheduling status in one sentence.
Response to assess
A morning workshop is proposed; Hall C confirmation is pending.
Practice
Case 2
Consider the proposed response for this fictional Cedar work task. Use the supplied packet and stated requirements.
Source packet
- Source 1
- Notice: Submit forms by 2 June unless a written extension has been granted.
- Source 2
- Summary brief: Include the deadline and any exception.
Response to assess
All forms must be submitted by 2 June without exception.
Fresh transfer
Case 3
Consider a fictional operational summary that omits decorative detail.
Source packet
- Source 1
- Source: The help desk moves to Room 7 on Monday. The notice uses a green border.
- Source 2
- Brief: Tell staff where and when to find the help desk.
Response to assess
From Monday, the help desk is in Room 7.
Fresh transfer
Case 4
Consider a fictional whole-report claim from a limited extract.
Source packet
- Source 1
- Extract: Pages 1–2 discuss possible opening hours.
- Source 2
- Receipt: Pages 3–6 are unavailable; this packet contains no final recommendation.
Response to assess
The full report recommends closing the center permanently.
Save your self-review
Completion records that you reviewed the cases. Your explanation and transfer performance need a facilitator to establish independent learning.

Review the explanation for every case before saving.
Summary and next step
Apply the checklist to a new task. Preserve supported content, explain any change with evidence, and name what remains unresolved. Saving records self-review, not independently demonstrated proficiency. A facilitator must assess the explanation and fresh transfer for human learning evidence.
