When not to use it

Trust this before you buy

  • If you need open weights, use the 2.4T A95B repo, not this API SKU. That sibling is lineage on the hub, not a Max download.
  • Not a Continuum hosted id. Official DeepSWE row is xhigh, not a silent default.
  • Closed API. Alibaba / Qwen official pages we opened were JS shells with no extractable dollar table. OpenRouter only for cents. No official GGUF on this SKU.

Plus is $25/mo with $25 weekly hosted usage. The Mac app stays free with your own keys. Get Plus is not Download for Mac.

Weights

Qwen3.8 Max has no HF id on OpenRouter. The open 2.4T repo is a sibling, labeled lineage, not a fake Max download.

  • OpenRouter catalog 19 Aug 2026: $2 / $6 per million, cache read $0.25 /M, cache write $2.50 /M, 1,000,000 / 131,072, created 1785731612. hugging_face_id empty.
  • Official Alibaba / qwen.ai pages opened 19 Aug 2026 were JS shells with no extractable per-million table. Omitted, not guessed. Use OpenRouter only.

What you can open

Lab card and OpenRouter listing only. No Hugging Face Files button, because there is no official repo to point at.

Fetched OpenRouter catalog on 2026-08-19. hugging_face_id was empty.

Continuum serving

Not listed as a Continuum hosted id. OpenRouter qwen/qwen3.8-max and first-party Qwen.

Continuum hosted id not on the host list

We list first-party and OpenRouter, plus Continuum only when the live public allowlist named the id. This is not a 15-host routing table.

Economics

DeepSWE official: $3.73 per task at xhigh (95k out, 111 steps). That is the hero economics number.

OpenRouter catalog 19 Aug 2026: $2 / $6 per million, cache read $0.25 /M, cache write $2.50 /M, created 1785731612. No official Alibaba per-M table extracted from the JS shell we fetched.

Artificial Analysis Qwen3.8 Max page (19 Aug 2026) prints the same $2.00 / $6.00 pair, 44.4 tok/s, and “it cost $1741.41 to evaluate Qwen3.8 Max on the Intelligence Index.” vals prints $3.997 per Index test and 90 min 46 s.

Price this model Opens the pricing calculator preloaded with Qwen3.8 Max.

Artificial Analysis Intelligence Index 58, fetched 19 Aug 2026. Same page prints $2.00 / $6.00, 44.4 tok/s, and $1741.41 to run the Index. The AA tile is the published integer 58. AA did not print a DeepSWE-style CI or step count we will copy onto the chip. Do not average AA cost with DeepSWE $3.73/task.

FAQ

Are the open 2.4T weights this SKU?

No. Qwen/Qwen3.8-2.4T-A95B is lineage on the hub. This card is the closed Max API. No fake Max download.

Official Alibaba $?

qwen.ai / Alibaba pages we opened were JS shells. No extractable per-M table. OpenRouter $2 / $6 plus cache $0.25 / $2.50 write is the sourced list.

Why does the lab blog disagree with DeepSWE or Scale?

Lab posts pick a harness, an effort, a split, and sometimes a private eval set. DeepSWE publishes the official mini-swe-agent row with cost, tokens, and steps. Scale SWE-bench Pro only counts when the public shared-harness board has a row we can fetch. A higher lab number is usually a different test, not a better one.

OpenAI-compatible call

No Continuum hosted id is verified for this model, so this page does not invent a curl target. Use the first-party API or the OpenRouter slug qwen/qwen3.8-max.

Plus is $25/mo with $25 weekly hosted usage. The Mac app stays free with your own keys. Get Plus is not Download for Mac.
