What Is the Artificial Analysis Intelligence Index—and How Is It Used Here?
The Artificial Analysis Intelligence Index is a composite score intended to summarize how capable AI models are across a set of evaluations. It can help readers compare models without scanning a dozen separate benchmark results. But a single score is only useful if you know what went into it, which version you are looking at, and what question you are trying to answer.
At Suprmind Data Lab, we use the index as one input in model tracking—not as a final verdict on which model is best. We pair it with release-date checks, task-specific evaluations, pricing, and evidence from real user preferences. That distinction matters. A model can score well on a benchmark and still be less useful for a particular team, more expensive to run, or less preferred in a blind comparison.
This guide explains what the index can tell you, where its limits are, and how we use it to assess releases from companies such as OpenAI and Anthropic. It also explains why we keep track of the index version, separate verified release dates from announced dates, and look for regressions as well as upgrades.
What the Artificial Analysis Intelligence Index measures
Artificial Analysis publishes model evaluations and comparisons, including an Intelligence Index that combines results from multiple tests into a summary view. Composite indexes are useful because models are rarely strong in exactly the same way. One may do better on coding tasks; another may perform better on questions involving knowledge or reasoning. A combined score offers a convenient starting point for comparison.
It is not a universal measure of intelligence, nor does it guarantee that a model will perform well on your workload. The meaning of a score depends on the index’s included benchmarks, scoring rules, and version. Those details can change as the index is updated. A score from one index version should not automatically be treated as directly comparable with a score from another.
In practical terms, use the index to ask, “How does this model compare across the evaluations included here?” Do not use it to claim, “This model is better for every job.” The first statement is bounded by the index. The second requires evidence from the work you actually need the model to do.
Why the index version matters
When an evaluation changes, a model’s score can move even if the model itself has not. The index may add or remove tests, change how results are combined, or adjust its evaluation process. That is why we record the index version alongside the score and the date we checked it.
Without that information, a chart can make unlike results look comparable. A model scored under one version may appear to have gained or lost ground against a model scored under another. The apparent change could reflect the model, the index, or both.
Our rule is simple: make like-for-like comparisons. When possible, compare models under the same index version and use results gathered under the same conditions. If the index version changed between observations, we mark that change rather than presenting the scores as a clean before-and-after comparison.
Announced dates are not the same as release dates
AI model timelines often begin with a blog post, a keynote, a preview, or a waitlist. Those are useful signals, but they are not always the date a model became generally usable. Access may start later, roll out gradually, or be limited to selected customers. An API announcement, a research preview, and broad availability describe different stages.
We therefore track two dates where the evidence supports it:
- Announced date: when the provider publicly announced or previewed the model.
- Verified release date: when we can confirm that the model became available to users through a stated channel, such as an API or product.
We do not silently substitute one for the other. If access details are unclear, we say so. This matters when comparing release cadence across labs. Counting every announcement as a launch can make a provider look faster than it was in day-to-day availability. A clear timeline helps teams see when a model could actually be tested, integrated, and adopted.
Blind-vote preference is a different signal from launch benchmarks
Benchmarks and user preference answer different questions. A launch benchmark tests performance on a defined set of tasks, often under a particular evaluation setup. A blind-vote comparison asks people to judge outputs without knowing which model produced them. It can provide a useful signal about which answer users prefer in those matchups.
One well-known source of preference data is LMArena, formerly LMSYS Chatbot Arena. Its text leaderboard includes a style-control option, which can help readers inspect comparisons with response-style effects in mind. The underlying data is also available through the Hugging Face dataset lmarena-ai/leaderboard-dataset.
Blind votes are not a substitute for task testing. Results depend on the prompts, participants, matchups, and evaluation setup. Preference can also reflect clarity, tone, or formatting—not just factual accuracy or reasoning. Conversely, a launch benchmark may test capabilities that users do not notice in a short preference comparison.
We treat the two as complementary evidence. The Artificial Analysis Intelligence Index can summarize performance across its included evaluations. LMArena-style preference results can show how people respond to outputs in blind comparisons. Neither alone tells a team whether a model is suitable for its production workflow.
How we use the index for upgrade decisions
When a provider releases a new model, a higher index score is a reason to investigate—not an automatic reason to migrate. The decision depends on the jobs the model needs to perform, the quality of the comparison, and the cost of the change.
Our review process is deliberately practical:
- Confirm availability. Record the announcement and verify when the model can actually be accessed.
- Check the comparison conditions. Note the index version, evaluation date, model variant, and any relevant access limits.
- Inspect the mix of evidence. Look at the composite score, component results where available, and blind-vote preference data.
- Run representative tasks. Test the prompts, tools, and output requirements that matter to the team—not just generic examples.
- Compare total cost and operational fit. Consider price, latency, reliability, context limits, and integration work.
- Check for regressions. Repeat key tests after an upgrade and look for losses in tasks the previous model handled well.
Regressions deserve attention because “newer” does not mean “better at everything.” A release may improve one type of reasoning while changing tone, formatting, tool use, or consistency elsewhere. That can create a real cost even if the headline score rises.

A capability score does not tell you whether a model is affordable at your usage level. Pricing should be checked against the provider’s current documentation and calculated for the team’s actual input and output patterns. A small per-token difference can matter at high volume; a larger price can still be justified if it reduces retries or handles tasks that previously required more work.
Illustrative price claim: GPT-5.2 was reported as costing about 40% more than GPT-5.1. Treat that figure as a lab claim with a secondary source, not as a verified, provider-issued price comparison. Before using it in a purchasing decision, check the relevant provider pricing pages, confirm the model versions and billing units, and recalculate for your own traffic. “About 40% higher” is not enough context to establish total cost across different workloads.
This is also why we avoid ranking models on capability alone. The practical question is not simply which model has the higher score. It is which model meets the required quality threshold at an acceptable cost and with tolerable operational risk.
What release cadence across labs can—and cannot—tell you
OpenAI and Anthropic, like other AI labs, release models, previews, and product updates on different schedules. Tracking those events can help teams plan evaluations and understand how quickly the available options are changing. But cadence is not a quality metric. More announcements do not necessarily mean more usable releases, and a slower schedule does not establish that a provider’s models are less capable.
For a useful timeline, count verified availability separately from public announcements. Note whether a release is a preview, a general API release, or a product update. Then compare what changed in daily use: capability on relevant AI model releases for healthcare tasks, price, access, latency, and behavior. That is more informative than a simple count of launch posts.
How to read our comparisons
When we refer to the Artificial Analysis Intelligence Index, we use it as a structured comparison point. We do not treat its score as a complete model review, and we do not imply that a score from a different index version is directly interchangeable. Where evidence is incomplete, we identify the gap instead of filling it with a guess.
For a reader evaluating a model, the useful questions are:
- Which index version produced the score?
- Were the models evaluated under comparable conditions?
- Is the date an announcement or a verified availability date?
- Do preference results agree with the benchmark picture—or point to a different strength?
- Does the model improve the tasks you care about, without unacceptable regressions?
- Does its cost and access model fit your use case?
Bottom line
The Artificial Analysis Intelligence Index is a useful orientation tool: it can summarize results across evaluations and help identify models worth testing. Its value depends on understanding the methodology, tracking the index version, and making like-for-like comparisons.
At Suprmind Data Lab, we combine that signal with verified release dates, blind-vote preference data from sources such as LMArena, task-specific testing, and price checks. The goal is not to declare a universal winner. It is to help teams decide whether a particular release is a meaningful upgrade for their work—and to spot the regressions, costs, or availability gaps that a headline score cannot show.
