FAQ

Questions before you commit

How much does Qwen3.8 Flash cost on Boundless?

$0.15 per 1M input tokens, $0.02 per 1M cached input tokens and $0.47 per 1M output tokens, billed from prepaid credits. Every response includes exact token counts, so any charge can be checked against these prices.

What is Qwen3.8 Flash's context window on Boundless?

1M tokens, shared by the prompt and the reply. max_tokens can go up to that limit.

Does Qwen3.8 Flash support tool calling?

Yes. Qwen3.8 Flash supports tool use and reasoning.

Can I control how much Qwen3.8 Flash reasons?

Yes. On chat completions, set reasoning_effort to none, low, medium or high, or leave it unset for the model's default. Size max_tokens for both the thinking and the reply.

Can Qwen3.8 Flash read images?

Yes. Qwen3.8 Flash accepts text, image as input.

What are the rate limits?

Each team has caps on tokens per minute, requests per minute and concurrent requests, shown on the usage page. Cached input doesn't count against them, and support can raise them for your team.

Does Boundless store my prompts or outputs?

No. Boundless never stores prompts or outputs and never trains on them. It keeps only what billing needs: token counts, model, timestamp and cost.

Can Boundless help me decide if Qwen3.8 Flash fits my workload?

Yes. We test it against your current model on your own prompts, then tune and run it to your targets.
