What Is an AI Research Agent?
A practical definition of AI research agents, their execution loop, institutional controls, failure modes and a reproducible evaluation protocol.

An AI research agent is software that receives a research objective, chooses and uses tools, observes the results, and repeats those steps until it produces a deliverable or asks for human help. A chatbot normally responds within a conversation. An agent controls part of the process that creates the response. In institutional research, the important additions are bounded data access, source-level evidence, run logs, approval points and explicit stop conditions.
There is no single settled industry definition. Anthropic defines an agent as a model that directs its own process and tool use, while OpenAI describes systems that independently accomplish tasks on a user's behalf. This page uses the narrower overlap of those definitions. We sell research agents at AllMind, so the product statements below about our own agents are first-party claims, not neutral findings.
The agent is the loop around the model
A language model alone maps an input to an output. An agent adds an execution loop and an environment. Anthropic's description of trustworthy agents summarizes the loop as planning, acting, observing and adjusting until completion or human input is needed. OpenAI's agent tooling announcement similarly emphasizes tools, orchestration and traces.
| Layer | Job in a research agent | Example evidence to preserve |
|---|---|---|
| Objective | Defines the deliverable and acceptance criteria | User request, template, due time |
| Planner | Chooses steps and revises them after new information | Plan versions and reason for change |
| Tools | Retrieve documents and data, calculate, write or export | Tool name, arguments, user identity, response ID |
| Working state | Holds intermediate files, tables and unresolved questions | File hashes, timestamps, source mappings |
| Verifier | Checks output against sources or deterministic rules | Claim-level checks, failures and corrections |
| Stop policy | Ends, escalates or requests approval | Completion rule, timeout, blocked condition |
| Deliverable | Produces the artifact the reviewer will use | Report, spreadsheet, source appendix, run ID |
The model can still make mistakes at every layer. It may choose the wrong source, call the right tool with a wrong identifier, interpret a correct value under the wrong period or decide too early that the work is complete.
Agent, workflow, copilot and chatbot
Autonomy is a spectrum, and labels are unreliable. Judge the control flow.
- A chatbot answers a message and waits for the next one.
- A copilot assists inside work the user is actively doing, such as proposing a formula or drafting a paragraph.
- A workflow follows steps and branches primarily defined in software.
- An agent chooses at least some steps or tools based on intermediate results.
A system can combine all four. A deterministic filing extractor may hand an exception to an agent, which uses tools to investigate and asks an analyst to approve a correction. That can be safer than allowing the model to decide every step.
Microsoft's Researcher documentation calls its product an agent because it handles multi-step research across web and permitted work content and returns a cited report. OpenAI's 2026 description of an agent computer environment shows a model proposing actions, receiving tool results and choosing the next step in an isolated workspace. These are useful implementations, but the name alone does not establish accuracy or control quality.
A research agent needs an evidence model
For financial work, a citation URL is only the beginning. A material claim should retain:
- source provider, document identity and stable URL or accession number;
- issuer or security identifiers;
- publication date, reporting period, units and currency;
- the exact passage, table cell or data response used;
- whether the claim was observed, vendor-reported, estimated or inferred;
- user and entitlement under which the source was retrieved;
- model, prompt or skill version and tool calls;
- review status and any correction.
This evidence envelope makes the deliverable reviewable. It also reveals failures that polished prose hides. If a source was unavailable, the agent should return a missing-source status rather than silently substitute an older or lower-quality document.
The ontology or data model underneath the agent matters when the task crosses entities. A question about portfolio exposure may require resolving a security to its issuer, a supplier to a parent company and a disclosure to a reporting period. The agent should not infer all those identities from similar text on every run. The financial ontology definition explains that schema and evidence boundary in detail.
An illustrative run, without pretending it happened
Suppose an analyst asks for a post-earnings variance note on one company. This is a process design, not a captured AllMind or competitor output.
- Resolve the company, security and fiscal quarter.
- Retrieve the filed earnings release, 10-Q or 8-K exhibits, call transcript, prior guidance and approved consensus source.
- Confirm the period, currency and share basis for each figure.
- Calculate actual-versus-consensus and actual-versus-guidance variances with a deterministic tool.
- Locate management explanations for the largest differences.
- Draft the note with each number linked to its source.
- Run checks for period mixing, stale estimates, arithmetic errors and unsupported causal language.
- Stop for analyst review before the note enters a model, email or client deliverable.
The agent adds value by coordinating the steps and handling exceptions. The deterministic calculations and approval point remain explicit. A system that simply writes a fluent note after searching the web has performed deep research, but it has not demonstrated an institutional earnings workflow.
The failure modes are more important than the demo
Agentic systems expand the number of actions that can go wrong.
| Failure | What it looks like | Useful control |
|---|---|---|
| Wrong identity | Data from a parent, subsidiary or similar ticker is mixed | Stable identifiers and entity-resolution test |
| Permission widening | Agent retrieves a note the user cannot access | Run as user, entitlement check at retrieval, access log |
| Source substitution | Missing primary source is replaced without disclosure | Source priority and explicit “not found” state |
| Tool misuse | Wrong date, unit or parameter is sent to an API | Typed tool schema, validation and boundary tests |
| Compounding error | Early extraction mistake flows through every later step | Intermediate checks and claim-level provenance |
| Premature completion | Agent stops with missing sections or sources | Acceptance criteria and completion validator |
| Unbounded action | Agent writes, shares or changes a system unexpectedly | Least privilege and approval for external actions |
| Irreproducibility | Same request cannot be reconstructed later | Versioned instructions, run log and source snapshots |
Longer run time is not proof of agency or quality. A slow report can still be a fixed workflow, and a fast tool-using system can still be an agent. Measure task completion, errors and review cost.
How to evaluate an AI research agent
Choose a deliverable your team already produces and define the pass criteria before the test.
Fix the inputs
Provide an exact issuer universe, date range, document set, data snapshot and output template. Record which sources each test user is entitled to access.
Include known traps
Use an amended filing, an issuer with a non-calendar fiscal year, a missing data field, a security with multiple listings and two users with different permissions. At least one task should require the agent to say it cannot complete a step.
Score observable outcomes
Track source coverage, material-claim accuracy, calculation accuracy, unsupported claims, permission violations, template completeness, elapsed time and reviewer minutes. Publish the denominator. “90% accurate” is meaningless without the claims counted and error definition.
Inspect the trace
Review which tools ran, under whose identity, with which arguments and source versions. Confirm that the final artifact preserves enough evidence for another analyst to reproduce it.
Rerun after change
Replace one source or correct one fact. The agent should identify the affected output and refresh it without silently changing unrelated sections.
When a workflow or copilot is the better choice
Use a fixed workflow when the steps are stable, the inputs are structured and errors are expensive. Use a copilot when analyst judgment is continuous and the user should remain in control of each edit. An agent is best suited to tasks with variable research paths, multiple tools and enough reviewable evidence to supervise the autonomy.
The cost of autonomy includes evaluation, logs, access controls, tool maintenance and exception handling. For a monthly extraction from a known table, ordinary software is likely the better system.
Inside AllMind's Agent Studio
Our Agent Studio runs repeatable investment-research work across connected sources and returns a cited memo, model, deck or scheduled brief. “Connected sources” includes an AllMind data estate of 750M+ documents and 6,800+ premium data sources licensed from 100+ providers and partners, not just files a customer uploads. That estate includes FactSet fundamentals and Revere relationships, LSEG estimates, S&P/Capital IQ market and index data, MSCI data, CME and other exchange feeds, filings, transcripts, broker research, Expert Insights, and alternative data. In our ontology, agents inherit user permissions and work from objects with evidence attached.
These are our own claims. We do not publish task-level accuracy, permission-test results, reviewer time or a dataset of failed runs. Ask us to run the evaluation above on your own source set and to show both the trace and the failure states. Our enterprise setup may also be unnecessary for a team whose tasks use only public sources and remain interactive.
Definition and product-source notes
The definition draws on Anthropic's trustworthy-agents explanation, OpenAI's agent tools and computer-environment descriptions, Microsoft's Researcher documentation and NIST's AI glossary. Sources were checked on August 30, 2026. Claims about AllMind link to our official pages and are our own; hold them to the evaluation above rather than to this page. No agent trace, product run or comparative benchmark was inspected. The process example is explicitly illustrative and should not be read as observed performance.
