Qwen 3.5 Plus API: 1M-context general model at a budget price
Qwen 3.5 Plus is Alibaba's previous-generation Plus model, offering strong general-purpose performance across reasoning, coding, and writing with a massive 1,000,000-token context window and 65K output ceiling.
Through YepAPI you call Qwen 3.5 Plus with one API key on the chat endpoint at $0.36 per 1M input and $2.18 per 1M output tokens — a budget-friendly way to access a 1M-context model.
What is Qwen 3.5 Plus?
Qwen 3.5 Plus is a previous-generation large language model from Alibaba's Qwen family. It is a balanced, general-purpose text-to-text model that performs well across reasoning, code generation, summarization, and writing tasks. Its standout feature is a 1,000,000-token context window, letting it process entire codebases, long document collections, or extended conversation histories in a single request, with up to 65,536 tokens of output. Positioned as the accessible Plus tier, it gives developers a dependable all-rounder with frontier-scale context at a price well below top-end models.
Build with Qwen 3.5 Plus via YepAPI
Send chat completion requests to Qwen 3.5 Plus over a single YepAPI key on the /v1/ai/chat endpoint — no Alibaba Cloud account or regional setup required. Pass your system and user messages, optionally streaming the response. The huge context window means you can include long documents or full repositories inline. Because one key spans the entire catalog, you can route long-context work to Qwen 3.5 Plus and switch to other models for different tasks without re-authenticating, making it easy to slot into existing pipelines.
Qwen 3.5 Plus API pricing — $0.36/1M input, $2.18/1M output
Qwen 3.5 Plus costs $0.36 per 1M input tokens and $2.18 per 1M output tokens on YepAPI. Given its 1M-token context window, that input price makes feeding very large prompts affordable, while balanced output pricing keeps long generations reasonable. You pay only for tokens used, with no minimums or seats, and one balance covers Qwen 3.5 Plus alongside every other model on the platform.
Qwen 3.5 Plus for long-context document work
Qwen 3.5 Plus is well suited to tasks that hinge on large inputs: analyzing or summarizing long reports, answering questions across entire document sets, reviewing big codebases, and maintaining long multi-turn conversations. The 1M-token window means you can keep everything in context rather than chunking, and its solid general performance handles the reasoning. For budget-conscious long-context workloads, it is a practical default.
