Where can you find price, speed, and task evidence for Claude Opus 4.8 and Qwen 3.8 Max?
Which tasks fit Claude Opus 4.8 and Qwen 3.8 Max?
Best-fit task signals from the published model strengths; this is not a substitute for a controlled benchmark.
| Fact | Claude Opus 4.8 | Qwen 3.8 Max |
|---|---|---|
| Best fit | Complex, multi-step tasks where Fable 5’s premium isn’t justified. | Frontier-class reasoning outside the US big-lab ecosystem. |
| Reasoning mode | Available | Available |
What does a Coding Agent workload cost with Claude Opus 4.8 and Qwen 3.8 Max?
Modeled for Coding Agent: 20,000 input + 2,000 output tokens per task, 1 turn. This is a workload model, not a provider quote.
| Fact | Claude Opus 4.8 | Qwen 3.8 Max |
|---|---|---|
| Coding Agent / task | $0.15 (modeled) | $0.04 (modeled) (winner) |
| Input / output rate | $5.00 / $25.00 per M | $1.60 / $6.40 per M |
How fast are Claude Opus 4.8 and Qwen 3.8 Max?
Only non-estimated benchmark results are shown as measured.
| Fact | Claude Opus 4.8 | Qwen 3.8 Max |
|---|---|---|
| Measured throughput | 58 tokens/s (winner) | 47 tokens/s |
| Time to first token | 470 ms | 470 ms |
How compatible are Claude Opus 4.8 and Qwen 3.8 Max with APIs?

| Fact | Claude Opus 4.8 | Qwen 3.8 Max |
|---|---|---|
| OpenAI SDK | Not drop-in | Not drop-in |
| Request shape | Messages API — system prompt is a top-level field, not a message role, and max_tokens is required on every call. | DashScope ships an OpenAI-compatible mode, but reasoning mode and some sampling params only work on the native DashScope endpoint. |
| Streaming | SSE (Anthropic content-block events) | SSE (OpenAI delta in compatible mode) |
What are the privacy and retention policies for Claude Opus 4.8 and Qwen 3.8 Max?
Provider policy and residency facts from the verified provider registry. A missing retention policy is not treated as a guarantee.
| Fact | Claude Opus 4.8 | Qwen 3.8 Max |
|---|---|---|
| Provider says API data trains models | No | Unavailable |
| Published retention period | Unavailable | Unavailable |
| Data residency | Unavailable | Singapore/international region via DashScope Intl; mainland China served from a separate region |
How much effort does it take to migrate between Claude Opus 4.8 and Qwen 3.8 Max?
Direction is from each displayed model to the other. Effort is derived from provider compatibility and published parameter maps.
| Fact | Claude Opus 4.8 | Qwen 3.8 Max |
|---|---|---|
| Move Claude Opus 4.8 → Qwen 3.8 Max | code-change; 1 breaking parameter difference | Target: Qwen 3.8 Max |
| Move Qwen 3.8 Max → Claude Opus 4.8 | Source: Qwen 3.8 Max | code-change; 3 breaking parameter differences |
| Why | DashScope ships an OpenAI-compatible mode, but reasoning mode and some sampling params only work on the native DashScope endpoint. | Messages API — system prompt is a top-level field, not a message role, and max_tokens is required on every call. |
