AI can generate and transform content, assist with demanding specialist work, and complete some structured computer tasks—but its ability is uneven, and a fluent answer is not proof of a correct one. Treat each system as a collection of task-specific capabilities, not as a single measure of intelligence. What it can do depends on the task, the information and tools it can access, and the conditions under which it is evaluated.
What does “AI capability” mean?
There is no single score that tells you what an AI system can do across every situation. A model may perform well on one kind of reasoning and poorly on a seemingly ordinary task; performance can also change with the language, modality, tools, or unfamiliarity of the input.

The OECD AI Capability Indicators assess nine areas separately: language, social interaction, problem solving, creativity, metacognition, knowledge and memory, vision, manipulation, and robotic intelligence. The indicators are beta, and their ratings describe the state of the art as assessed in November 2024—not a current product ranking. On the language scale, its authors Yvette Graham, Arthur Graesser, and Swen Ribeiro describe the most advanced LLMs at that time, including the model used by ChatGPT, as “roughly at level 3.” That statement applies to the scale and assessment period, not to every capability of a chatbot.

The OECD notes that symbolic AI systems can exceed human performance in areas such as logistics planning and model checking. A strong result in a tightly defined task does not establish broad, human-like competence. The OECD overview also identifies hallucination as a persistent challenge across the domains it reviewed.

What can AI do today?
Generate and transform content
Generative systems can create or revise text and other media, and they can help turn material from one form into another—for example, by drafting, summarizing, or reformatting content. The existence of this ability does not establish that the output is accurate, original, or reliably attributable to a particular person or system.
NIST’s GenAI program evaluates generators, detectors, and prompters across text, image, code, audio, and video. Its scope is evaluation across modalities, not a claim that every AI product supports every modality. NIST describes its program as rigorous, science-based testing of these systems.
Help with demanding, well-defined tasks
Stanford HAI’s 2026 AI Index reports that several frontier models met or exceeded human baselines on PhD-level science questions, multimodal reasoning, and competition mathematics. These are results on selected evaluations; they do not show that the same models will be dependable across everyday work or unfamiliar problems.
Rank #2
The same report says performance on SWE-bench Verified rose from 60% to near 100% in a year. That figure concerns performance on this software-engineering benchmark, not success on software engineering as a whole. More than 90% of notable frontier models in 2025 were produced by industry, according to the report; this describes who developed them, not how capable or reliable they are. Stanford HAI’s 2026 AI Index gives the benchmark context.
Carry out some structured computer tasks
AI agents can interact with software to complete sequences of actions. In Stanford HAI’s 2026 account of the OSWorld benchmark, agents achieved about 66% task success and still failed roughly one in three attempts. That result is evidence of progress on the structured benchmark, not a success rate for every computer-use agent, application, or workplace deployment.
What can AI not reliably do?
Guarantee that an answer is true
An AI system can produce a confident, plausible-sounding answer that is false, incomplete, or unsupported. Stanford HAI’s 2026 Responsible AI chapter reports hallucination rates ranging from 22% to 94% across 26 top models on a new accuracy benchmark. Those figures apply to that benchmark; they are not the odds that any given response from any AI system will be wrong.
The errors can also vary with language and context. In a Slovenian commonsense evaluation cited by Stanford HAI in 2026, several leading models lost close to half their accuracy when tested in a regional dialect. A result in one language variety should not be assumed to transfer to another.
Generalize every benchmark win to ordinary work
Strong performance on an advanced mathematics test can coexist with poor performance on a basic visual task. Stanford HAI’s 2026 AI Index reports that the top model’s analog-clock reading accuracy was 50.1%, an example of this “jagged” capability profile. The score describes that evaluation, not every vision task or every model.
Learn continuously from ordinary conversations by default
The OECD’s capability framework characterizes leading LLMs it assessed as pretrained, non-adaptive systems and identifies dynamic learning as a limitation. A conversation may affect the replies within that session without changing the underlying model. Product-specific memory, personalization, or update features vary and need to be checked for the particular service; do not assume that an assistant will retain information or improve itself from each interaction.
Make safety and authenticity judgments foolproof
Safety performance can weaken under adversarial inputs, and Stanford HAI reports that responsible-AI benchmark reporting is much less common than capability benchmark reporting. Its 2026 chapter also records 362 documented AI incidents in 2025, up from 233 in 2024, drawing on the AI Incident Database. Incident counts describe documented cases, not the probability that a particular use will cause harm.
Detection tools are not universal proof of authorship or authenticity. In a NIST text-summarization pilot, three generators fooled every detector in that test. NIST’s finding is specific to that pilot; it does not mean every detector fails on every kind of content. NIST’s GenAI program evaluates generators and detectors across multiple modalities, including adversarial comparisons.

Match the amount of checking to the consequences of being wrong. For brainstorming or a low-stakes first draft, a quick review may be enough. For medical, legal, financial, safety-critical, or consequential workplace decisions, treat AI as an assistant—not the final authority—and have a qualified person verify the facts and reasoning before acting.
Best Value
- Check factual claims against reliable sources. Ask for sources when useful, then open them and confirm that they support the specific claim. A citation supplied by a model is not verification by itself.
- Test the actual task. Try representative examples, including edge cases, before relying on a system. A broad label such as “good at coding” or “strong at reasoning” is less useful than evidence on the work you need done.
- Review actions, not just answers. If an AI can use tools or change files, accounts, or settings, inspect proposed actions and outputs before allowing consequential changes.
- Protect sensitive information. Check the service’s data-handling terms and your organization’s rules before entering personal, confidential, or regulated material.
- Keep a human accountable. Decide in advance who checks the work, who can correct it, and when the system should not be used.
How to read AI benchmark claims
A benchmark is a measurement of performance on a defined set of tasks under particular conditions. It can reveal useful strengths or expose weaknesses, but it is not a complete evaluation of truthfulness, safety, robustness, or suitability for your work. Stanford HAI notes the gap between the prevalence of capability benchmark reporting and responsible-AI benchmark reporting; a high capability score alone therefore leaves important questions unanswered.
When comparing a claim, look for the details that determine whether it applies to your use:
- Task and modality: What exactly was tested—text, images, code, audio, video, or computer interaction?
- Conditions and errors: What counted as success, what kinds of mistakes occurred, and were unfamiliar or adversarial inputs included?
- Language and users: Which languages, dialects, and user contexts were represented?
- Tools and oversight: Could the system browse, run code, or act in an environment, and how much human supervision did the test include?
- Date and version: Which model and configuration were evaluated, and when? Capabilities and product features change, so older findings should not be presented as a current ranking.
The OECD indicators provide a framework for separating capability domains, but are beta and reflect a November 2024 assessment. Stanford HAI’s 2026 figures offer newer snapshots for their named evaluations. Neither source, by itself, is a complete, current comparison of consumer AI products.
