Expensive isn't necessarily right

Qwen Office Members Can Now Use the Economy Model for Free

On August 18, Qwen Office entered its second week of public beta testing. Starting today, members can use the economy model indefinitely and without usage limits.

During these two weeks, the main feedback we received wasn't just a simple "Is it easy to use?" but more specific questions such as: "Which Qwen Office model should I actually choose?"

Qwen Office offers three models—"Economy," "Basic," and "Advanced"—with cutting-edge models like Qwen3.8-Max continuously being added.

Different tiers correspond to different task purposes, but most users' real confusion lies in this—will the economy model suffice for simple tasks? Is choosing the advanced model safe for complex ones? And in which scenarios does the middle-tier model truly justify its cost?

Rather than discussing theories abstractly, let's conduct a practical test.

We designed three tasks of increasing difficulty: from single-step shallow output, to multi-constrained reasoning, and finally long code generation. Each was assigned to the three models to observe their actual performance in terms of time spent, point consumption, and completion quality.

Cutting-edge models are continually being updated and will not be included in this evaluation round.

Now, let’s begin the three-stage test.

L1 Simple Task: Table Conversion

This is a typical "translation-type" task: moving data from one container to another with formatting constraints. Though low in difficulty, it tests the model’s fundamental ability in file parsing and tool utilization.

All three models successfully completed the task, but the economy model was faster and consumed fewer points.

Conclusion: For simple tasks, the economy model is more than sufficient.

L2 Multi-Constraint Task: Scheduling Assignment

This task raises the challenge. The model must simultaneously handle constraints such as staff skills, working hours, scheduling, and delivery order, while structuring results into an AI table. The key isn’t just “can it be done,” but whether accurate decisions can be made under multiple constraints.

A distinction begins to emerge. The basic and advanced models were faster and achieved higher completion rates. The economy model saved on points but struggled slightly with complex reasoning. Overall, the basic model delivered the best value.

Conclusion: For everyday complex tasks, the basic model offers better cost-effectiveness.

L3 Long Output Task: HTML Generation

This requires integrating eight constraints including collapsible navigation, KPI cards, line charts, bar charts, etc., to generate a complete, executable front-end project. This scenario closely resembles real-world development, with no templates available—the model must reason step by step from architecture design to detailed implementation.

Facing tasks with higher complexity and longer reasoning chains, the advanced model outperformed both economy and basic models in speed and output quality, while point consumption remained reasonable.

Conclusion: For complex, long-horizon reasoning tasks, the advanced model delivers faster and higher-quality results.

Test Conclusion: It's Not About Price, But Fit

After three rounds of testing, we’ve reached a clear conclusion.

The logic behind model selection is actually quite straightforward:

For daily simple tasks, the economy model is more than adequate.

For complex, multi-step tasks, the basic model provides the best value.

For long-horizon reasoning tasks, the advanced model is both faster and superior in quality.

Match the right model to the right task. That’s the original intention behind Qwen Office’s three-tier model design—not to push you toward the most expensive option, but to help you pick the most valuable one for every task.
