Is Qwen better than Claude?
Neither wins outright, because Qwen and Claude win on different measures in the same Aug 25, 2026 test. Qwen 3.7 Plus took all 32 questions of a real customer's client sign-up form, saved every answer, and did it at a fraction of the usual cost. Claude Opus 5 built the most complete sign-up form of that test at by far the highest cost, and Claude leads on follow-up changes. Pick Qwen for value on a long form. Pick Claude for finish and for changes after the first build. In Taskade, Claude runs on Pro and up with your own Anthropic API key.
TL;DR: Same test, different wins. On Aug 25, 2026, Qwen 3.7 Plus carried all 32 questions of a real customer's client sign-up form at a fraction of the usual cost, but it started both follow-up edits and finished neither. In that same test, Claude Opus 5 built the most complete sign-up form and the best-executed match tracker, at by far the highest cost, while Claude Sonnet 5 wrote the plan instead of the app. Claude leads on follow-up changes. Match the model to the job, and ship the result with Taskade Genesis.
What TSK-1 Found
Both families met in the same test on Aug 25, 2026: a real customer's request, an app we open and use ourselves, and a finished app read back against the brief. That day was Qwen's first hands-on test. Claude also carries evidence from Jul 30 through Aug 6, 2026, and every finding below is dated.
Qwen is the value story. Qwen 3.7 Plus took all 32 questions of the client sign-up form, saved every answer, and did it at a fraction of the usual cost. Its apps are plainer than the leaders' apps, and it saved less around the app. Qwen 3.7 Max built a complete match tracker on its first run.
Claude is the finish story, and Aug 25, 2026 showed both sides of it. Claude Opus 5 built the most complete client sign-up form of the test: a five-page form, every answer saved, and the scoring automation graded the submission on its own. Opus 5 also built the best-executed match tracker of the test, without a single failed build action, at by far the highest cost. Claude Sonnet 5 stopped after asking its questions on the sign-up form and wrote the plan instead of the app. Claude Haiku 4.5 was the fastest build of the test, but it left out the weekly recap automation the brief asked for. Claude also leads on follow-up changes, which is exactly where Qwen 3.7 Plus fell short.
- Qwen: Aug 25, 2026: Plus carried all 32 questions of the sign-up form at a fraction of the usual cost; Max built a complete match tracker on its first run; Plus started both follow-up edits and finished neither.
- Claude: Jul 30, 2026: Opus 5 set the design high-water mark and Sonnet 5 opened its own app to check the assistant's answers. Aug 1, 2026: Opus 5 created the fullest workspace of that test. Aug 3, 2026: Sonnet 5 produced our most carefully finished result, with eight minor items left.

Qwen 3.7 Plus vs Claude Sonnet 5
On the long form, Qwen 3.7 Plus finished and Claude Sonnet 5 did not. On everything after the first build, Sonnet 5 is the safer pick. The two met on the same 32-question client sign-up form on Aug 25, 2026, a real customer's request in which every question has to appear in the app and save correctly. Qwen 3.7 Plus took all 32 questions, saved every answer, and did it at a fraction of the usual cost.
Claude Sonnet 5 stopped after asking its questions on that same form and wrote the plan instead of the app. Its earlier record on the form is also mixed. On Aug 3, 2026, it built a contacts database instead of the requested sign-up form after two stalls. On Aug 6, 2026, four attempts stalled before the form was completed. Losing details in a long request is the Claude family's main risk. Against Sonnet 5, Qwen 3.7 Plus wins the long form on value and on completeness. Against the Claude family as a whole, it does not: in the same Aug 25 test, Claude Opus 5 built the most complete client sign-up form of the test, with every answer saved and the scoring automation grading the submission on its own, at by far the highest cost. Qwen's win is a value win. Opus 5's win is a completeness win that you pay for.
The picture flips once the app exists. Qwen 3.7 Plus started both follow-up edits and finished neither: a new page was written but never linked into the app, so the user would never have found it. Claude handles follow-up changes especially well, and it leads on that measure among the families we test. Sonnet 5 also opened its own app and checked the assistant's answers (Jul 30, 2026), the only model to verify its work that way, and on Aug 3, 2026 it produced our most carefully finished result, with eight minor items left.
Qwen 3.7 Plus also has an honest ceiling. Its apps are plainer than the leaders' apps, and it saved less around the app. On a harder field-inspection brief it left the inspector with nothing to do on day one, because the checklist could not start until a weekly automation had run. Value on the form is real. The follow-up edit is where it stopped short.
Qwen 3.7 Max vs Claude Opus 5
Both built a complete match tracker in the same Aug 25, 2026 test. Claude Opus 5 executed it best, at by far the highest cost. Qwen 3.7 Max made it work, with one silent gap. Qwen 3.7 Max built a complete match tracker with a clean dashboard on the first run, and it saved a real match once a hero was picked. With the hero left blank, the save button did nothing and said nothing: a first-use trap for a real user, and the kind of thing a business owner discovers from a customer. That is why we open every app and use it.
Claude Opus 5 built the best-executed match tracker of that same test, without a single failed build action, at by far the highest cost. That is the trade in one sentence: the cleanest build in the test and the most expensive one. On Jul 30, 2026, it set the design high-water mark with a polished, consistent interface. On Aug 1, 2026, it created the fullest workspace of that test, with an assistant that understood its contents. On the Qwen side, Qwen 3.7 Plus built its match dashboard quickly on Aug 25, 2026, but with the thinnest workspace behind it of any model in the test. Both families can put a working screen in front of you. What sits behind the screen, and what it costs, is where they differ most.
Claude Haiku 4.5 adds two more data points. On Jul 31, 2026, it found a problem while building that would have left the app blank, repaired it, and then finished, the only model in that test to recover on its own. On Aug 25, 2026, it was the fastest build of the test, but it left out the weekly recap automation the brief asked for. Read the finished app back against the brief before you trust it.
Choose Qwen If…
- The job is a long, detailed form and the budget is tight. Aug 25, 2026 is the standing evidence: Qwen 3.7 Plus carried all 32 questions of the client sign-up form, saved every answer, and did it at a fraction of the usual cost, on the day Claude Sonnet 5 wrote the plan instead of the app.
- You want a working dashboard on the first run. Qwen 3.7 Max built a complete match tracker with a clean dashboard the first time, and Qwen 3.7 Plus built a working match dashboard quickly (Aug 25, 2026).
- Your input includes images or video. Alibaba lists text, image, and video input for Qwen 3.7 Plus.
- Volume is high and much of it can wait. Alibaba bills batch calls at half price and discounts cache hits.
- You want a family with an open-weight option. The two tiers on this page run on Alibaba's service, but other Qwen generations publish weights under Apache 2.0.
Choose Claude If…
- The finish matters. Opus 5 built the best-executed match tracker of the Aug 25, 2026 test and set the design high-water mark (Jul 30, 2026). Sonnet 5 produced our most carefully finished result (Aug 3, 2026).
- The form has to be complete and cost comes second. Opus 5 built the most complete client sign-up form of the Aug 25, 2026 test, with the scoring automation grading the submission on its own, at by far the highest cost.
- You will change the app after the first build. Claude leads on follow-up changes, and that is exactly the step where Qwen 3.7 Plus started two edits and finished neither.
- You want a full workspace behind the app. Opus 5 created the fullest workspace of the Aug 1, 2026 test, with an assistant that understood its contents. Qwen 3.7 Plus had the thinnest workspace of the Aug 25, 2026 test.
- You want a model that checks and repairs its own work. Sonnet 5 opened its own app and checked the answers (Jul 30, 2026). Haiku 4.5 repaired a problem while building and finished (Jul 31, 2026).
- You need a published rate card you can plan against. Haiku 4.5 at $1 in and $5 out, Sonnet 5.5 at $2 and $10, and Opus 5.5 at $4 and $20 per million tokens, with the full 1M-token context billed at standard rates (as of Sep 2026).
The Taskade Angle: Match the Model to the Job
Most comparison pages end with "pick one". The evidence points the other way: one family owns value on a long form, the other owns finish and follow-up changes. Serious teams use both and match each to the job.
Taskade Genesis runs frontier models from top AI labs with Auto as the default, and the AI allowance is included in the subscription rather than a separate API account per lab. Paid plans start at Pro $10/mo billed annually, with Business $25, Max $100 and Enterprise $250 per month billed annually. Claude is the exception to the included allowance: it runs in Taskade on your own Anthropic key, through the Anthropic Claude connector or BYOK for agents, both on Pro and up. Leave a step on TSK-1 Auto and it adapts the depth instead: fast when the step is quick, deeper reasoning when it is not.
Four patterns that hold up:
- Value model builds the form, finish model polishes it. The 32-question form on a value model, then the visual pass on Claude through your own Anthropic key.
- First build on one model, every change on another. Qwen builds it, Claude changes it. That is the split the Aug 25 follow-up finding argues for.
- Every step lands in the same project graph. Whichever model runs a step, the result becomes shared workspace memory for the next agent.
- Scheduled automations read from the same place. Each step can call your own Anthropic account through the connector.
Frequently Asked Questions
Which is better, Qwen or Claude?
They win on different measures, and they met in the same test on Aug 25, 2026.

Its apps are plainer than the leaders' apps, and it saved less around the app. Claude Opus 5 built the most complete sign-up form of that test, at by far the highest cost, and Claude leads on follow-up changes. Its main risk is losing details in a long request. Pick Qwen for value on a long form. Pick Claude for finish and for changes after the first build. In Taskade, Claude runs on Pro and up with your own Anthropic API key.
What happened in the Aug 25, 2026 Qwen test?
Qwen 3.7 Plus carried all 32 questions of the client sign-up form and saved every answer at a fraction of the usual cost. It also built a working match dashboard quickly, but with the thinnest workspace behind it of any model in the test. It started both follow-up edits and finished neither: a new page was written but never linked into the app. On a harder field-inspection brief it left the inspector with nothing to do on day one, because the checklist could not start until a weekly automation had run. Qwen 3.7 Max built a complete match tracker with a clean dashboard on the first run.
Where did Claude do best?
Finish and follow-up changes. On Aug 25, 2026, Claude Opus 5 built the most complete client sign-up form of the test, a five-page form with every answer saved and the scoring automation grading the submission on its own, and the best-executed match tracker of the test, without a single failed build action, at by far the highest cost. On Aug 3, 2026, Claude Sonnet 5 produced our most carefully finished result, with eight minor items left. On Jul 30, 2026, Sonnet 5 opened its own app and checked the assistant's answers, and Opus 5 set the design high-water mark. Claude Haiku 4.5 repaired a problem that would have left its app blank (Jul 31, 2026).
Where did each family miss?
We publish the misses beside the wins. On Aug 25, 2026, Qwen 3.7 Plus started both follow-up edits and finished neither, and on a harder field-inspection brief it left the inspector with nothing to do on day one. Qwen 3.7 Max saved a real match once a hero was picked, but with the hero left blank the save button did nothing and said nothing. In that same test, Claude Sonnet 5 stopped after asking its questions on the sign-up form and wrote the plan instead of the app, and Claude Haiku 4.5 left out the weekly recap automation the brief asked for. Earlier, Sonnet 5 built a contacts database instead of the form (Aug 3, 2026).
Which Qwen and Claude models are live right now?
Alibaba Cloud Model Studio lists qwen3.7-plus and qwen3.7-max. Qwen 3.7 Plus accepts text, images, and video as input and returns text. Both run on Alibaba's own service, and no Qwen 3.7 weights appear on the official Qwen page on Hugging Face. Anthropic lists Claude Sonnet 5.5, Claude Opus 5.5, and Claude Haiku 4.5, plus the Fable 5.1 tier above them. Taskade Genesis runs frontier models from top AI labs with Auto as the default. Claude does not draw on Taskade credits: it runs in Taskade on your own Anthropic key, through the Anthropic Claude connector or BYOK for agents, both on Pro and up. The Aug 25 results below are dated test history, not a list of models you can pick today.
How much do they cost?
Anthropic publishes its API rates. As of September 2026, Claude Haiku 4.5 is $1 per million input tokens and $5 per million output, Claude Sonnet 5.5 and Sonnet 5 are $2 and $10, Claude Opus 5.5 is $4 and $20, and Claude Opus 5 was $5 and $25. The planned Sonnet increase to $3 and $15 did not happen, so $2 and $10 is the standard price. For the current lineup, see Claude models explained. Batch requests are 50 percent off in both directions, and a cache hit bills at a tenth of the input rate. Alibaba publishes Qwen 3.7 Plus and Max rates on the Model Studio pricing page, with batch calls at half price and a discount on cache hits. Read both rate cards at the source before you commit, because prices move.
What are the context windows?
Both families reach a million tokens. Alibaba lists a 1,000,000-token context for Qwen 3.7 Plus with a maximum output of 131,072 tokens, and bills Qwen 3.7 Max on a single tier up to 1M tokens. Anthropic lists a 1M-token context for Claude Sonnet 5 and Claude Opus 5 with a maximum output of 128K tokens, and 200K tokens with 64K output for Claude Haiku 4.5. Anthropic bills the full 1M window at standard rates, so a very long request costs the same per token as a short one. Context length is not the deciding factor between these two families.
Are the Qwen models open-weight?
Not the two on this page. Qwen 3.7 Plus and Qwen 3.7 Max run on Alibaba's own service, and no Qwen 3.7 weights appear on the official Qwen page on Hugging Face. Other Qwen generations do publish open weights under Apache 2.0, so the family gives you a self-hosting option even though its newest tiers do not. Claude weights are never released. If you need weights on your own hardware, neither Qwen 3.7 tier nor Claude is a candidate, and the older open Qwen line is where to look.
Which one should I use for an AI agent?
Match the model to the step. Reach for Qwen 3.7 Plus when the step is a long, detailed form and cost matters: it carried all 32 questions and saved every answer at a fraction of the usual cost. Reach for Claude Sonnet 5 when the step changes an app that already exists, or when a customer will see the result. Reach for Claude Opus 5.5 when the finish matters most and cost does not. In Taskade Genesis, agents and automations share the same workspace memory, and Claude steps run on your own Anthropic key.
Can I use Qwen and Claude together with Taskade?
Partly. Taskade Genesis runs frontier models from top AI labs with Auto as the default, and the AI allowance is included in the subscription. Claude runs in Taskade only on your own Anthropic key: on Pro and up, the Anthropic Claude connector runs Claude in automations, and BYOK lets agents run on a Claude model. For a Qwen-plus-Claude split, use the model row that fits each step and bring your own key for Claude. Leave a step on TSK-1 Auto and it adapts the depth instead: fast when the step is quick, deeper reasoning when it is not.
Final Word: Value vs Finish
Qwen is the value pick: all 32 questions of the client sign-up form saved at a fraction of the usual cost, plus a complete match tracker on the first run from Qwen 3.7 Max, all on Aug 25, 2026. Its apps are plainer, its workspace is thinner, and its follow-up edits did not finish. Claude is the finish pick: the most complete sign-up form and the best-executed match tracker of that same test from Opus 5, at by far the highest cost, plus the lead on follow-up changes. Its long-request risk showed up the same day, when Sonnet 5 wrote the plan instead of the app. Both families reach a million tokens of context, so the choice is about the job, not the window.
Neither is the winner. The winner is the setup that puts value where the form lives and finish where the customer looks.
