Alibaba Qwen series — Chinese-first LLMs with strong bilingual support. Wide range from turbo to max tiers.
When Thinking mode is enabled, reasoning tokens generated by the model are counted as billable output. This can increase total usage beyond the visible answer tokens.
Alibaba's alibaba/qwen3.5-122b-a10b is a frontier text generation model in the Qwen family. It excels at complex reasoning, agentic workflows, code generation, and long-form writing tasks, with native support for streaming, tool calling, JSON mode, and multi-turn conversations.
The model handles long-context inputs gracefully and is particularly effective for software engineering, multi-step research, and end-to-end project execution. Its tokenizer and pricing are optimized for high-throughput production workloads, with a competitive cost profile relative to other models in its tier.
alibaba/qwen3.5-122b-a10b is fully OpenAI-compatible — drop in your existing OpenAI Python or Node SDK and switch `baseURL` to `https://api.tokenlx.ai`. TokenLX transparently routes your requests to the optimal provider endpoint while preserving streaming, function-calling, and structured-output semantics.
Compare different providers across TokenLX · All locations.
Actual cost per million tokens across providers over the past 7 days.
Total usage per day on TokenLX (last 30 days).
TokenLX normalizes requests and responses across providers. Use any OpenAI SDK or our native SDK.
Disable Thinking when you do not need explicit reasoning, or set a lower budget_tokens value to cap the reasoning length. Only enable return_thoughts when you need to inspect the thinking process.
