Alibaba this week released Qwen3.7-Plus, the latest AI large language model (LLM) in its globally beloved and increasingly expansive Qwen family, boasting more multimodal capabilities and a 60% lower cost than the prior, text-only Qwen3.7-Max model released just weeks ago. However, like its immediate predecessor Qwen3.7-Plus is available only under a “closed” commercial license via proprietary application programming interfaces (API) and Qwen Chat. That marks a big departure from the Qwen strategy to date, which was focused mainly on releasing powerful,near state-of-the-art open source models. Those enterprises and users who relied on the open source Qwen models — among them, U.S. giants such as Airbnb — will no doubt be disappointed to see that Alibaba is going closed for its newer releases.Still, the model is worth a look because of its low cost and high performance on multimodal tasks like creating enterprise-grade visuals or analyzing video, imagery and screenshots, which Qwen3.7-Max cannot do (it’s text-only). It is among the cheaper powerful AI models available now, coming in price-wise just above Chinese rival’s new MiniMax-M3’s limited-time discount pricing.

Instead, it is state decay—the tendency of an agent framework to lose its analytical trajectory over multi-step, long-horizon tasks. Qwen3.7-Plus addresses this architectural vulnerability through a combined approach to context management and reasoning state preservation. The model ships with a 1-million token context window and allocates up to 256K tokens specifically for internal chain-of-thought processing. To contextualize this capacity, imagine an automated cloud migration agent: it can ingest an entire codebase, map out the dependencies, and spend thousands of tokens quietly evaluating edge cases before executing a single line of bash script.Crucially, the API exposes a parameter called ‘preserve_thinking.’ Across Alibaba’s ecosystem, the capability serves as a standardized architectural bridge rather than a tiered perk. Alibaba introduced the feature during the prior Qwen 3.6 generation, integrating it into both the open-weight Qwen3.6-27B and the proprietary Max models. At its core, the parameter operates at the API and template level to retain internal blocks across continuous conversational turns.This structural continuity solves a critical bottleneck for developers engineering long-horizon tasks. By keeping these internal logic loops intact, the feature prevents the model from dropping its context or needlessly recomputing its cached history midway through an operation. When a model executes complex, multi-step agentic coding assignments, this retention allows the system to hold onto its original train of thought without losing the plot or forgetting the underlying logic of its previous actions.Alibaba remains far from alone in recognizing this technical necessity, as the underlying concept now dictates the architecture of nearly all major artificial intelligence laboratories. Anthropic deploys this exact capability under the moniker “Extended Thinking” for its advanced models, including its latest Claude Opus 4.8. This framework requires developers to feed unmodified thinking blocks directly back into the API on subsequent turns to maintain an unbroken chain of reasoning. OpenAI tackles the same challenge through an encrypted reasoning pass-back mechanism for models like GPT-5.5. Within the OpenAI ecosystem, developers must return specific reasoning items generated alongside previous function calls, ensuring the model explicitly remembers the rationale behind its tool executions. Ultimately, preserve_thinking simply represents Alibaba’s terminology for what has rapidly become the undisputed table stakes for modern multi-turn reasoning.Benchmarks show a competitive, yet sub state-of-the-art modelOn raw capability metrics, this deep-thinking architecture translates to structural gains across multimodal and agentic benchmarks. However, it still falls below many of the leading and prior generations of U.S. proprietary models such as Anthropic’s Claude Opus 4.6 and OpenAI’s GPT-5.4.On Terminal Bench 2.0-Terminus, which measures an model’s capability to run actual terminal-level code safely and iteratively, Qwen3.7-Plus scored 70.3, outperforming DeepSeek-V4-Pro Max (67.9) and Gemini-3.1 Pro (63.5). On computer vision benchmarks that demand localized interface understanding, such as ScreenSpot Pro, the model hit 79.0, significantly outpacing legacy industry standouts like GPT-5.4 (xhigh) at 67.4 and Claude-Opus-4.6 at 49.5. Agent Evaluation Metrics (Selected Benchmarks)What should enterprises consider Qwen3.7-Plus for?For an enterprise architect, the key question when analyzing Qwen3.7-Plus is clear: What does this replace in our current tech stack?The model is designed to step in as a direct replacement for premier frontier models (such as GPT-5-tier or Claude-Max-tier models) within high-frequency developer workflows, robotic process automation (RPA), and data engineering pipelines. Rather than deploying an expensive, general-purpose flagship model to handle repetitive system operations, …
