Qwen / qwen/qwen3.8-flash-free
Qwen3.8-Flash (Ucretsiz) - access through LLMTR
The same model as Qwen3.8-Flash, offered free for a limited period through a separate card. It provides an 800,000-token context window and produces at most 131,072 tokens per response; it accepts image input alongside text, and video input is not supported on this card. Native tool calling, JSON object mode and JSON Schema structured output all work. Repeated prefixes are served from the prompt cache, but since this card is already free the benefit is LATENCY, not a lower price. Step-by-step reasoning is on by default, returned separately from the answer, and can be switched off per request. While reasoning is on, tool_choice forms that force a tool call ('required' or a named tool) are not supported; switch reasoning off in the same request to use them. IMPORTANT: this card has a limit of only a few requests per minute that is SHARED across all users; when it is full you receive an error telling you when to retry, usually in under a minute. For sustained or heavy use, the metered qwen/qwen3.8-flash card serves the same model without that limit and with a wider context window (1,000,000 tokens). The free period ends on 22 September 2026: after that date this card retires and requests return an error naming its successor, and nothing is charged until you change the model id yourself.
