Qwen3.7 Plus example: reading an image into JSON

The example is picked from this model's own capabilities. Drop in your key and it runs as is.

What is Qwen3.7 Plus good for?

Qwen3.7 Plus is one of Qwen (Alibaba)'s models. Put "qwen/qwen3.7-plus" in the model field and the rest of your code stays as it is. Qwen3.7 Plus keeps 1,000,000 tokens in view at once, and that number is what caps the conversation history in your product. A single response can run to 131,072 tokens. On price it sits in the "cheap" band — cheaper than 225 and dearer than 173 of the other paid models in the catalogue.

What it can do beyond plain text: it reads images directly, which makes it a real option for invoices, forms and screenshots; it supports tool calling, so it can invoke your own functions with valid arguments; it returns schema-valid JSON through response_format, ready to hand to your code; it has a reasoning mode that pays off on multi-step problems, maths and debugging. All of it works through the standard parameters of the official OpenAI SDK — no custom client, no wrapper. Keep in mind that reasoning tokens are output tokens and do appear on the bill.

Pricing is 110,790 toman per 1M input tokens and 443,161 per 1M output tokens. A 1,000-word round trip on Qwen3.7 Plus lands near 720 toman. It supports cached input: repeated context is billed at 22,158 toman per 1M, which matters a lot if your system prompt is long. You are always charged for the usage the request actually reported, never for the estimate, and a failed request costs nothing.

The closest alternative with the same capabilities from a different provider is Hy4, and Qwen3.7 Plus costs about the same, and its context window is smaller. Both run on the same key and the same code, so trying the other one is a single string change.

To make the figure concrete: 100,000 toman of credit buys roughly 139 thousand-word requests on Qwen3.7 Plus, and every 1,000 toman is about 1,389 words of round trip. A job with one million input tokens and one million output tokens comes to 553,951 toman in total. Filling this model's 1,000,000-token window costs 110,790 toman on the input side alone, which is the real reason to keep conversation history short.

This id gets confused with "qwen/qwen3.7-plus:batch", because the underlying model is the same. The difference is the suffix: no suffix (the standard variant) against "batch". On a thousand-word request this variant works out about 40% more expensive (720 against 518 toman). The context windows differ too: 1,000,000 against 262,144 tokens.

Qwen (Alibaba) has 42 models in our catalogue; the cheapest is Qwen3.7 Flash at 72 toman per thousand words and the dearest Qwen3.8 Max Prime at 7,201. Among the less common parameters it accepts logprobs, presence_penalty, top_k, top_logprobs — all through the standard request body. By context size the nearest option from another provider is Nova 2 Lite at 1,000,000 tokens.

Good fits: high-volume work such as classification, tagging and bulk summarising, logic puzzles and code review, pulling text and fields out of images, agents that reach out to APIs and databases, extracting data against a fixed schema, analysing a long document or codebase in one request.
