DeepSeek R1 vs Qwen3 235B A22B

DeepSeek · China  |  Alibaba · China · Updated June 2026

Quick verdict

Pick DeepSeek R1 for open-weight reasoning model or transparent chain-of-thought. Pick Qwen3 235B A22B for deep world knowledge from 235b total parameters (83.0 mmlu-pro, 93.1 mmlu-redux) or exceptional multilingual and alignment results (79.2 arena-hard v2, 85.2 writingbench). On a tight budget at scale, Qwen3 235B A22B is the value pick.

DeepSeek R1 (DeepSeek) and Qwen3 235B A22B (Alibaba) are two of the models people most often weigh against each other in 2026. DeepSeek R1 is the open-weight reasoning model that reset price expectations in early 2025. Qwen3 235B A22B is an older 235B text-only open mixture-of-experts with broad knowledge and strong writing — but no vision, no thinking mode, and weak coding. They diverge most on price and context window — each quantified below from the models' real specs.

Who wins what

Open-weight reasoning model

DeepSeek R1

Qwen3 235B A22B is comparatively weak here — text-only with no vision, and the absence of a thinking mode caps its hardest reasoning

Transparent chain-of-thought

DeepSeek R1

DeepSeek R1 lists transparent chain-of-thought among its strengths; Qwen3 235B A22B does not.

Low cost

DeepSeek R1

DeepSeek R1 lists low cost among its strengths; Qwen3 235B A22B does not.

Deep world knowledge from 235B total parameters (83.0 MMLU-Pro, 93.1 MMLU-Redux)

Qwen3 235B A22B

An older 235B text-only open mixture-of-experts with broad knowledge and strong writing — but no vision, no thinking mode, and weak coding — and it carries the larger 256K context.

Exceptional multilingual and alignment results (79.2 Arena-Hard v2, 85.2 WritingBench)

Qwen3 235B A22B

An older 235B text-only open mixture-of-experts with broad knowledge and strong writing — but no vision, no thinking mode, and weak coding — and it is the newer of the two.

Outstanding structured logic — 95.0 on ZebraLogic

Qwen3 235B A22B

Qwen3 235B A22B lists outstanding structured logic — 95.0 on ZebraLogic among its strengths; DeepSeek R1 does not.

Lowest cost at scale

Qwen3 235B A22B

Its weights are open, so at volume you pay for your own hardware instead of DeepSeek R1's $0.55/$2.19 per 1M tokens.

Largest single-prompt input

Qwen3 235B A22B

Its 256K window is about 2× larger than DeepSeek R1's 128K, fitting roughly 393 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

Qwen3 235B A22B

At Open weight (self-host / free) it undercuts DeepSeek R1, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

Qwen3 235B A22B

Larger 256K window fits more in one prompt.

Anyone whose priority is open-weight reasoning model

DeepSeek R1

It is specifically built for that.

Anyone whose priority is deep world knowledge from 235b total parameters (83.0 mmlu-pro, 93.1 mmlu-redux)

Qwen3 235B A22B

That is its strongest area.

DeepSeek R1: where it fits

The open-weight reasoning model that reset price expectations in early 2025. Released January 2025 by DeepSeek, it is built for open-weight reasoning model, transparent chain-of-thought, low cost, and strong maths and code.

Its trade-offs are real: older than V4, smaller 128K context, and text/code focused. At $0.55 in / $2.19 out per million tokens, it sits in the budget price band.

Qwen3 235B A22B: where it fits

An older 235B text-only open mixture-of-experts with broad knowledge and strong writing — but no vision, no thinking mode, and weak coding. Released July 21, 2025 by Alibaba, it is built for deep world knowledge from 235B total parameters (83.0 MMLU-Pro, 93.1 MMLU-Redux), exceptional multilingual and alignment results (79.2 Arena-Hard v2, 85.2 WritingBench), outstanding structured logic — 95.0 on ZebraLogic, and no thinking mode, which makes latency and token spend entirely predictable.

Its trade-offs: nearly a year old and superseded — Artificial Analysis now steers users to Qwen3.5-397B instead, text-only with no vision, and the absence of a thinking mode caps its hardest reasoning, coding is weak by 2026 standards, and it publishes no SWE-Bench score to compare on, and its 235B weights need roughly 438GB in BF16, far beyond consumer hardware. As an open-weight model, its running cost is your own hardware rather than a per-token fee.

The bottom line for this matchup

DeepSeek R1 and Qwen3 235B A22B overlap enough that the right pick depends on your specific job. Qwen3 235B A22B costs less per token; Qwen3 235B A22B holds the larger context; and each leads in its own area — DeepSeek R1 for open-weight reasoning model, Qwen3 235B A22B for deep world knowledge from 235b total parameters (83.0 mmlu-pro, 93.1 mmlu-redux). Rather than crowning one, run the same hard task through both once and let the results decide.

Frequently asked questions

Is DeepSeek R1 or Qwen3 235B A22B better for coding?

Public SWE-Bench figures are not available for either model, so the honest test is your own repository — run an identical real bug through both. By design, DeepSeek R1 leans toward open-weight reasoning model while Qwen3 235B A22B leans toward deep world knowledge from 235b total parameters (83.0 mmlu-pro, 93.1 mmlu-redux), and that positioning usually predicts which feels better on your codebase.

Which is cheaper, DeepSeek R1 or Qwen3 235B A22B?

Qwen3 235B A22B is cheaper — $0.55/$2.19 per 1M tokens vs Open weight (self-host / free).

Which has the bigger context window?

Qwen3 235B A22B — 256K vs 128K, about 2× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both DeepSeek R1 and Qwen3 235B A22B together?

Yes — a multi-model platform like LumiChats gives you DeepSeek R1, Qwen3 235B A22B and 40+ others under one ₹69/day pass (about $1/day), so you can draft with one and cross-check with the other instead of buying two subscriptions.

Which is newer, DeepSeek R1 or Qwen3 235B A22B?

Qwen3 235B A22B — released July 21, 2025, about 6 months after DeepSeek R1.
