Qwen vs DeepSeek: Models, API, Pricing and Deployment

Last verified: August 4, 2026 for Qwen3.8 Max Marketplace pricing and output limits; DeepSeek models and peak/off-peak pricing were rechecked August 23, 2026. Qwen vs DeepSeek is an ecosystem and deployment comparison, not one fixed model against another. Qwen includes current hosted services and separately released open-weight checkpoints. DeepSeek’s current first-party API centers on deepseek-v4-flash and deepseek-v4-pro, while DeepSeek also publishes model weights separately.

Short answer: shortlist Qwen when you need a broad model family, QwenCloud or Alibaba Cloud integration, multiple price tiers, or a specific Qwen checkpoint. Shortlist DeepSeek when its focused V4 API, published low token prices or V4 weights fit the workload. Neither brand is a universal winner. Test exact model IDs with the same data, settings and acceptance criteria.

Current status at a glance

Context and output values are capacity specifications, not quality scores. A consumer chat interface, third-party host or local checkpoint may expose different limits from the first-party API.

The current Qwen side

QwenCloud’s August 3 release note calls qwen3.8-max its flagship and documents a native vision-language model, a 2.4-trillion-parameter mixture-of-experts architecture, hybrid thinking enabled by default and a 1M-token context window. The model-specific QwenCloud Marketplace page checked August 4 lists a 131K maximum output and PAYG list prices of $2 input and $6 output per 1M tokens. These figures are not an Alibaba Cloud Model Studio regional quote.

For reproducible pricing, this page uses two established Model Studio routes: qwen3.7-max and qwen3.7-plus in the Singapore International deployment. Qwen also publishes open-weight checkpoints, but a hosted alias and a downloadable checkpoint are not interchangeable. Confirm the exact artifact, license and runtime requirements in the Qwen model reference and Qwen download guide.

The current DeepSeek side

DeepSeek’s current pricing page maps deepseek-v4-flash to DeepSeek-V4-Flash-0731 and deepseek-v4-pro to DeepSeek-V4-Pro-0813. Both document a 1M context window, a maximum 384K output, thinking and non-thinking modes, JSON output, tool calls, the Responses API, the Anthropic API and Chat Prefix Completion. FIM completion is documented only in non-thinking mode.

Retired DeepSeek aliases

The old deepseek-chat and deepseek-reasoner API model names were scheduled to become inaccessible after July 24, 2026 at 15:59 UTC. Before retirement, they mapped to V4 Flash non-thinking and thinking modes. That transition is now past. New integrations should use the current documented IDs rather than describing retirement as a future event.

Qwen vs DeepSeek API pricing

Prices below are first-party USD list prices per 1 million tokens and are not performance-equivalent model pairs. The Qwen3.8 Max row is QwenCloud Marketplace PAYG checked August 4; the Qwen3.7 rows are Singapore International Model Studio routes checked August 3. Do not transfer a price between those routes. DeepSeek separates cache hits from cache misses and applies different peak and off-peak rates. Taxes, promotions, batch discounts, tools, retries and negotiated terms are excluded.

Alibaba applies the relevant Qwen3.7 Plus tier to all tokens in a request once the request crosses the tier threshold. DeepSeek now publishes peak and off-peak rates. Peak hours are 01:00–04:00 and 06:00–10:00 UTC; other weekday hours use off-peak rates. Effective August 23, 2026, off-peak rates also apply throughout Saturdays and Sundays in Beijing time. Confirm the live pricing page before budgeting because schedules and rates can change.

For a maintained Qwen-by-region matrix, see the Qwen API pricing guide. For endpoint and migration guidance, use the Qwen API guide. Prices from a third-party host must not be substituted for either first-party table.

API compatibility and migration

Both ecosystems can reduce integration work through familiar API formats, but “compatible” does not mean feature-identical. DeepSeek documents separate OpenAI-format and Anthropic-format base URLs. Alibaba Cloud Model Studio documents OpenAI-compatible access for supported Qwen models. Parameters, response fields, reasoning controls, tool schemas and error behavior can still differ.

• Pin an exact model ID or dated snapshot when behavioral stability matters.
• Do not carry a deprecated alias into production merely because an SDK accepts the string.
• Test streaming, structured output, tool calls and reasoning controls separately.
• Log response model IDs, usage fields, request IDs and errors without storing secrets.
• Keep API keys server-side and verify retention and processing terms for the selected route.

Open weights and self-hosting

Both families have separately published weights, but the exact checkpoint controls the license, parameter count, memory requirement, context configuration and supported runtime. A first-party hosted Max, Plus, Flash or Pro name does not automatically identify a downloadable equivalent.

Self-hosting can provide infrastructure control, but it does not eliminate cost. Measure accelerator time, replicas, idle capacity, storage, networking, monitoring and engineering. Do not publish a universal tokens-per-second or VRAM claim without a dated test on the exact checkpoint, quantization, runtime, accelerator and concurrency.

Coding, agents and long context

Provider documentation positions both current families for reasoning, coding and tool use, but those descriptions do not establish a head-to-head winner. A 1M context specification also does not prove that a model will use every part of a long repository equally well. Long prompts can increase cost, latency and retrieval noise.

For a coding or agent workflow, evaluate repository navigation, edit correctness, test execution, tool selection, recovery after tool errors and total tokens per accepted change. Record the scaffold and tool definitions because they can change the result as much as the model name.

Methodology and limitations

This update is a documentation audit based on first-party model, pricing, release and lifecycle pages. Qwen sources were checked on August 3–4, 2026 and DeepSeek sources on August 23, 2026. It did not make login-dependent API calls, run private consoles, measure latency or score responses. No sample output or benchmark result is presented as our own.

A future live comparison should use identical dated prompts and files, explicit scoring rules, fixed model IDs, recorded thinking settings and tools, multiple runs for variable tasks, and a complete record of errors, token usage, latency and cost. Results would apply only to the tested versions and settings.

Frequently asked questions

Is Qwen cheaper than DeepSeek?

Not universally. Against the cited Qwen3.7 Plus first band, DeepSeek V4 Flash has a lower output price at both times and a lower cache-miss input price off-peak, but its peak cache-miss input price is slightly higher. Cache behavior, time window, route, context band and quality requirements all affect the result.

Can I still use deepseek-chat or deepseek-reasoner?

DeepSeek announced that both aliases would be inaccessible after July 24, 2026 at 15:59 UTC. Use the currently documented V4 IDs and test the required thinking mode.

Is Qwen3.8 Max free?

No. QwenCloud Marketplace lists PAYG prices of $2 input and $6 output per 1M tokens for qwen3.8-max. Promotions or credits can have separate terms, and this Marketplace price must not be treated as a Model Studio regional rate.
