Microsoft has launched Decision-1, a 9‑billion‑parameter Qwen3.5‑based model for AI decision scoring, with pricing, benchmark results and comparisons to competing offerings.
Microsoft has added a new specialist model to its AI portfolio: Decision‑1, a 9‑billion‑parameter system built on Alibaba’s Qwen 3.5‑9B architecture. Launched on 10 September 2026 via the Microsoft Foundry marketplace (and also listed on OpenRouter), the model is purpose‑trained for “decision scoring” – it ingests a fixed set of answer options and returns a calibrated probability for each in a single pass, rather than generating free‑form text.
Microsoft’s own benchmarks show Decision‑1 achieving the highest average accuracy across 36 structured‑decision tasks, with an 83.5 % score. Latency is equally striking: the model processes inputs in about 85 ms, a fraction of the 3.01 seconds recorded for the comparable GPT‑6 Sol baseline. The model supports a 32,768‑token context window, enabling it to handle extensive input data while remaining lightweight enough for rapid inference.
The launch matters because it signals a shift toward narrowly focused, high‑efficiency models that can replace larger, more costly LLMs for routine classification, routing, ranking, grading and binary‑decision workloads. Enterprises that need to triage support tickets, prioritize incidents, filter content, or evaluate other model outputs can now do so with a dedicated engine that promises both speed and accuracy at a modest scale.
Going forward, observers will watch how Microsoft prices the service and whether it integrates Decision‑1 into broader Azure AI offerings. Real‑world adoption rates, especially in high‑throughput environments, will test whether the model’s benchmark edge translates into cost savings and performance gains. Competitors may respond with their own decision‑oriented models, potentially sparking a niche market for specialized, low‑latency AI scoring tools.
