Decision reading

Qwen3.8 Max has the higher public score estimate, 69.82 versus 65.78, but the 90% score intervals overlap. Treat that as a lead, not a settled winner. 18 results are shared. Category rows resting on Estimated evidence or different benchmark sets are marked directional and do not name a winner.

Which one for your work

Recommendations appear only when a shared evidence basis or an explicit operating constraint supports the call. Secondary and unsupported use cases stay disclosed below the initial list.

  • Coding work

    Code generation, repair, and software-engineering tasks

    DeepSeek V4.1 Flash 1017

    DeepSeek V4.1 Flash 1017 has the higher public coding point estimate, 61.1 to 53.4, with Supported evidence for both models. The conditional ranges do not establish rank confidence.

    Confidence: limited
  • Agentic work

    Tool use, computer use, and multi-step task completion

    Qwen3.8 Max

    Qwen3.8 Max has the higher public agentic point estimate, 67.4 to 61.7, with Supported evidence for both models. The conditional ranges do not establish rank confidence.

Which one for a specific job

Choose a job from the LLM Selector's task catalog to see the category row it rests on, under the same basis rules as the table below. A directional row stays directional; choosing a job never creates a winner.

The same task catalog as the LLM Selector. Each job names the evidence surface it rests on; nothing here adds a new score.

Like-for-like · BenchAlign v5.8

DeepSeek V4.1 Flash 1017 has the higher coding point estimate. Conditional score ranges do not establish rank confidence.

Coding scores combine specific tasks and setups. Match the editor, harness, and effort to your workflow.

What is actually comparable

Shared results can support a head-to-head reading. Results present for only one model describe coverage, not superiority.

Shape of the matched evidence

Only shared public evidence is shown. Sparse evidence stays a ruled list rather than being closed into a radar shape.

Too few matched category axes support a radar. The ruled list below shows only shared benchmark results; positions use each benchmark’s normalized display scale when available.

Bars run 0–100 on each benchmark’s normalized display scale

Category results, on a stated basis

Each row shows the public-lane category score for both models: the BenchAlign v5.8 lane for agentic, coding, and knowledge, and the weighted public rows elsewhere, with the same rank each model page reports. A row is like-for-like only when both scores rest on Supported evidence or the same weighted set. Directional and not-comparable rows remain visible, but they never receive a winner.

Ranks count the models scored in each category’s lane, so the agentic, coding, and knowledge denominators (BenchAlign v5.8) differ from the provisional-lane categories. Unranked scores sit on the provisional lane’s scale but never name a winner. Like-for-like rows within 0.5 points read as a practical tie.

What each workload costs

Three fixed token mixes turn per-token rates into comparable decisions. Each scenario states context fit and whether cached input had to fall back to the published list-input rate.

Questions

Which is better, DeepSeek V4.1 Flash 1017 or Qwen3.8 Max?

Qwen3.8 Max has the higher public score estimate, 69.82 versus 65.78, but the 90% score intervals overlap. The higher estimate is not a decisive winner because the uncertainty ranges overlap.

Which is better for coding, DeepSeek V4.1 Flash 1017 or Qwen3.8 Max?

DeepSeek V4.1 Flash 1017 has the higher public coding point estimate, 61.1 to 53.4, with Supported evidence for both models. The conditional ranges do not establish rank confidence.

Which is better for agentic tasks, DeepSeek V4.1 Flash 1017 or Qwen3.8 Max?

Qwen3.8 Max has the higher public agentic tasks point estimate, 67.4 to 61.7, with Supported evidence for both models. The conditional ranges do not establish rank confidence.

Which costs less, DeepSeek V4.1 Flash 1017 or Qwen3.8 Max?

Both models do not have comparable published API token rates, so this page does not name a universal price winner.

Which has the larger context window, DeepSeek V4.1 Flash 1017 or Qwen3.8 Max?

Both models list the same context window, 1M.
