Intelligence doesn’t always need to get bigger. It can become specialized.

Abstract illustration: a fixed foundation at the center of a field of experts. One expert engages at a time and draws on the foundation, which never changes size.

We’re introducing Meridian Air CivoE, our Civilization of Experts: specialized intelligence delivered by experts that share one compact foundation model.

On a selected evaluation drawn from 14 public benchmark datasets, Meridian Air CivoE increased the underlying model’s average score from 59.8 to 85.5 out of 100.

In this evaluation, CivoE performed in the same statistical range as Gemini 4 and scored above the tested Claude Opus 5.5 and GPT-5.6 configurations.

The more important finding is that substantial new capabilities can be developed through specialization without replacing the underlying foundation.

Meridian Air is shipping in the webAI app beginning November 4, 2026. Meridian Air CivoE will roll out to users over the following weeks, with feedback informing continued improvements.

About these results

These are internal results, based on a benchmark suite curated around specialized tasks. They are not a claim that Meridian is a universally superior foundation model.

Same foundation. A different level of capability.

Specialization substantially changed what the model could accomplish on the tasks we evaluated.

What specialization changes

Composite score on the same evaluation items: the Meridian Air foundation on its own scored 59.8 out of 100; Meridian Air CivoE scored 85.5, an improvement of 25.7 points.

The 25.7-point improvement was measured across the same selected evaluation items. It does not mean every task improves by that amount, or that the increase would necessarily hold across unrelated workloads.

The result demonstrates the potential of specialization within the tested domains.

How does a specialized 12B system compare with frontier AI?

The most useful way to answer that question is to evaluate the models on the same problems. We tested Meridian Air CivoE against frontier and open-weight models using selected items drawn from 14 public benchmark datasets.

The results show that a compact, specialized system can achieve frontier-competitive performance on certain categories of work.

Family-level differences have not been tested for statistical significance. Differences under 2 points are marked as small and should not be read as superiority. Several tasks are custom evaluations built from public datasets with modified prompts, labels or scorers. Prompt-injection frontier results are published by others from different setups, not models we tested. Their rows plot both results on a 0 to 100% scale rather than the ±15-point difference scale.

Understanding the two largest task-family advantages

Personal-data detection

Our specialized system reached 91.8 on the combined personal-data evaluation, compared with 76.8 for the strongest tested frontier comparator.

This matters because recognizing sensitive information is a critical step in many enterprise document workflows.

The evaluation was built from Gretel PII and Nemotron PII datasets using a specific structured extraction task. The strongest difference occurred on Nemotron PII; the advantage on Gretel PII was considerably smaller.

Further testing is needed across new document types, entity taxonomies, and operational settings.

Photo understanding

Meridian scored 74.9 across the selected VizWiz evaluation items, compared with 60.9 for the strongest tested frontier comparator.

This suggests that targeted specialization can improve image question answering for a particular user need.

The reported scores come from selected validation items and a filtered test subset under the lab's evaluation protocol. They are not an official VizWiz leaderboard ranking.

Real-world reliability, accessibility outcomes, and performance across new photographs still need to be measured.

What happens when intelligence scales through specialization?

These results matter beyond one model or one benchmark. They suggest six directions worth investigating.

The biggest model isn’t always the best model for the job.

For much of the industry’s development, capability improvements have been associated with larger models, more training compute, and increasingly expensive infrastructure. Those methods remain important.

But our results show that a 12B foundation, equipped with task-specific expertise, can achieve performance comparable to much larger general-purpose systems on selected workloads.

This doesn’t mean small models have caught up on every dimension of intelligence. It means model size alone cannot tell us which system will be most useful for a particular task.

Research question

How many meaningful capabilities can be added while keeping the foundation fixed?

Diagram: as capabilities are added, the general-purpose model grows larger, while the Meridian Air foundation stays the same size and experts are added around it.

Intelligence may grow through expertise, not only parameters.

Today, building a more capable AI system often means improving or replacing its foundation model. Specialization offers a different possibility.

A shared foundation can support a growing civilization of experts, each developed to improve a particular capability. This suggests a path toward systems that acquire a broader collection of useful skills without requiring an entirely new foundation model for every additional task.

Our research demonstrates substantial improvement across selected specialized tasks. It does not yet establish how this architecture performs with hundreds or thousands of experts. That is one of the central questions we intend to investigate.

Research question

Can the number of useful capabilities grow while accuracy and operational efficiency remain strong?

Diagram: a field of points inside a fixed boundary. Choosing a kind of work pulls the points into a different arrangement; the boundary and the number of points never change.

More useful work from the compute we already have.

The cost of intelligence isn’t determined solely by how much intelligence a model contains. It also depends on how much computation is required to solve the task.

A compact foundation with task-specific experts could make some repeatable workflows more economical than sending every request to a large general-purpose model. The potential is especially important for high-volume enterprise tasks, where small differences in cost per successful operation compound across millions of requests.

But lower total operating cost has not been established by this benchmark. We still need matched measurements of hardware utilization, memory usage, throughput, latency, training costs, and successful task completion.

The opportunity is significant. The economic evidence remains to be completed.

Research question

When does specialization improve the full economics of useful intelligence?

Intelligence Delivery Network

Zero-trust, peer-to-peer intelligence on devices you already own. Select one to send a request.

Diagram: five devices connected directly to one another, with no central server. A request from one device goes straight to a peer that can handle it, and both devices are verified before the connection opens.

These measurements will be published only when supported by matched experiments. No estimates are shown.

Conceptual. Devices and connections are illustrative, and this evaluation was not run on the network.

Intelligence should be something you can own.

If compact systems can deliver the capabilities organizations need, more useful AI work could run on infrastructure those organizations control. Instead of depending exclusively on externally hosted general-purpose models, businesses, institutions, researchers, and eventually individuals could deploy specialized capabilities close to their data, their applications, and their work.

This has implications for autonomy, resilience, accessibility, and control. But local execution by itself does not guarantee privacy or security. Those properties also depend on identity, permissions, tool access, network behavior, and where information is disclosed.

This particular CivoE evaluation was conducted through a server-based inference environment using dequantized Q4 weights. It did not independently establish production performance on consumer devices.

Research question

Can specialized intelligence operate reliably, privately and economically across heterogeneous personal and enterprise hardware?

Diagram: your data sits inside a boundary that stands for infrastructure you control. With a hosted model, requests carry copies of that data across the boundary to a large model outside it. With an owned model, Meridian Air CivoE and its experts run inside the boundary, next to the data.

Conceptual, not to scale. Running on hardware you control doesn’t by itself make a system private or secure; identity, permissions, tool access and network behavior still matter.

Harder to trick, by design.

Prompt injection is one of the most persistent problems in AI security. Untrusted text, hidden in a document, an email or a web page, tricks a model into ignoring its original instructions or its safety guardrails.

A single general-purpose model reads that text and decides what to do in the same step, so one successful trick can redirect everything it does.

A Civilization of Experts divides the work. In our tests, one expert reads the untrusted material, a Critic expert checks the work, and the model that writes the final answer never sees the raw text. To change the outcome, an attacker has to get past several experts, not one.

On three public prompt-injection benchmarks, Meridian Air on its own followed injected instructions in up to 56% of attacks. Meridian Air CivoE followed none. On agent attacks, that matches the most resistant frontier results published. On instructions hidden in emails, a published test found Claude Opus 5 still followed 59%. Harder is still not impossible, and the results come with limits, listed with the chart.

Research question

Does this resistance hold against adaptive attacks, and what does it cost in speed and everyday task completion?

Injected instructions followed

Of 512 prompt-injection attack cases across three public benchmarks, 137 got through against Meridian Air alone and 0 against Meridian Air CivoE. Attack success by benchmark, lower is better: BIPIA: Meridian Air alone 56.0%, Meridian Air CivoE 0%, Claude Opus 5 59.0% in a published result from a different setup; AgentDojo: Meridian Air alone 26.4%, Meridian Air CivoE 0%, GPT-5 0.2% in a published result from a different setup; InjecAgent: Meridian Air alone 2.5%, Meridian Air CivoE 0%, Claude Opus 5 0% in a published result from a different setup.

Attack success rate: the share of attack cases in which the model followed the injected instruction. Lower is better.

Meridian Air CivoE ran as Researcher, Analyst, Writer, Builder and Critic experts on Meridian Air, once per case. The same workflow without the trained experts let through 1.5% of attacks on BIPIA, 0% on AgentDojo and 0% on InjecAgent, so the coordination provides most of the protection. It completed fewer benign AgentDojo tasks (63.9% vs 76.3%), still followed the planted instruction in 50% of 60 synthetic trap briefings, and makes two to nine model calls per task. Frontier results are published, not run by us, and use other test subsets, prompts and settings: BIPIA and InjecAgent from Khairnar (2026), AgentDojo from Meta-SecAlign (2026) without added defenses. Each is the most resistant frontier model its source reports, and the same model can score very differently from one setup to the next, so read them as context, not rankings. Resisting these attacks is not a guarantee of privacy or security.

Real intelligence is useful intelligence.

General-purpose benchmarks help measure broad capabilities. But the value of AI ultimately comes from what it helps people accomplish: understanding a difficult document, identifying sensitive information, making sense of a photograph, finding information in a contract, completing an operational task accurately.

Our results suggest that specialization can produce meaningful improvements on some of these narrowly defined activities. It is particularly encouraging that some of the largest measured gains were in personal-data detection and question answering over photographs.

These are not proof of real-world impact, but they identify applications worth testing with actual users. The promise of specialized intelligence is not merely higher benchmark scores. It is making capable AI more useful in the circumstances where people need it.

Research question

Can benchmark improvements translate into reliable, measurable improvements in everyday work?

  • Identifying sensitive informationRelevant expert:Personal-data detection
  • Making sense of a photographRelevant expert:Photo questions
  • Finding information in a contractRelevant expert:Contract clauses
  • Completing an operational task accuratelyRelevant expert:Banking intent classification

Verified input-to-output examples from the evaluation will appear here once their licensing is cleared for publication. We don’t show synthetic demonstrations as evidence.

The future of intelligence may be more specialized than we imagined.

Our results do not show that small models have replaced frontier AI. They show that a compact foundation, equipped with the right expertise, can perform at a remarkably high level on selected tasks.

That raises a larger possibility. Instead of depending only on bigger foundation models, we may build intelligence that grows through specialization, collaboration, and more efficient use of the infrastructure people already own.

A civilization of experts: each one useful, working together, under the control of the people and organizations they serve.

This is the direction we’re exploring at webAI. And we’re sharing the work because the best way to understand its limits and potential is to let others test it.

Meridian Air is arriving in the webAI app. Meridian Air CivoE follows over the coming weeks.
