The model scores 31 on the Artificial Analysis Intelligence Index, an 18-point gain over Inkling Small, but its higher token usage and per-task cost may affect how it performs in real workflows.<\/p>\n<p>Thinking Machines, the startup founded by former OpenAI CTO Mira Murati, announced the release of Inkling 2 Small on November 6, 2026. It is the company&#8217;s second model generation and is designed primarily as a base model for fine-tuning.<\/p>\n<h2>What Makes Inkling 2 Small Different?<\/h2>\n<p>Inkling 2 Small is a mixture-of-experts model with 594 billion total parameters. Seventeen billion parameters are active at any given time. It accepts text and images, and its adjustable thinking depth lets users choose between speed and thoroughness.<\/p>\n<p>According to Thinking Machines, the model scores 31 on the Artificial Analysis Intelligence Index. That is 18 points above Inkling Small, which scored 13, and roughly on par with Google&#8217;s Gemini 3.8 Flash.<\/p>\n<p>Its strongest improvements appear in agentic work, where a model completes multi-step workflows independently. On AutomationBench-AA, the score rose from 5 percent to 46 percent. On FrontierCode 2.0, it increased from 5 percent to 25 percent. On the AA-Briefcase knowledge-work benchmark, Inkling 2 Small reached an Elo score of 1,527, which was 615 points above its predecessor.<\/p>\n<h2>Earlier Open-Weight Model Releases<\/h2>\n<p>Inkling 2 Small\u2019s position among Western open-weight models reflects a broader pattern of downloadable models with specialized capabilities. In the <a href=\"http:\/\/epoch.ai\/publications\/open-weight-models-patch-gap\" target=\"_blank\" rel=\"noopener\">GLM 5.3 patch-gap exploit<\/a>, Z.ai released the widely available open-weight model in August 2026. It identified and exploited vulnerabilities in recent Mozilla Firefox versions, building a webpage that could read a file from a visitor\u2019s computer and send it to an attacker without further interaction. The experiments compromised six recent Firefox releases at about $1,000 each, and any Firefox version released between September 17 and October 26 could be compromised using information available at release.<\/p>\n<p>The <a href=\"https:\/\/llm-stats.com\/organizations\/openai\" target=\"_blank\" rel=\"noopener\">GPT OSS open-weight release<\/a> came earlier. OpenAI released GPT OSS 120B and GPT OSS 20B in August 2025, with listed sizes of 116.8B and 20.9B parameters. These releases establish the context for Inkling 2 Small, where the focus is agentic work, coding, and visual understanding, while the earlier events emphasize model availability and a cybersecurity exploit experiment.<\/p>\n<h2>What Does the New Intelligence Cost?<\/h2>\n<p>Higher scores come with greater token use and a higher cost per task. Artificial Analysis says Inkling 2 Small produces about 150,000 output tokens per task on average, roughly four times the output of Inkling Small. At $1.18 per task, it costs nearly six times as much as its predecessor.<\/p>\n<p>That cost remains below the alternatives tested by Artificial Analysis. Gemini 3.8 Flash costs $7.77 per task, while Claude Sonnet 5.5 costs $10.02. Inkling 2 Small therefore falls closer to the price range of lower-cost Chinese models.<\/p>\n<p>The lower hallucination rate also requires context. Inkling 2 Small&#8217;s rate falls from 61 percent to 27 percent, but its response rate falls from 77 percent to 53 percent. The model reaches the new rate by declining more questions.<\/p>\n<h2>How Does It Perform in Coding and Visual Tasks?<\/h2>\n<p>Thinking Machines says reinforcement learning on hundreds of thousands of long-horizon coding tasks shaped the new model. An automated evaluation system checked whether generated code worked and how the model approached each task.<\/p>\n<p>On FrontierCode 2.0, Inkling 2 Small reaches 25.4 percent. It scores 72.1 percent on DeepSWE and 86.3 percent on SWEBench Pro v2 (Hard). DeepSeek-V4.1-Flash remains ahead on FrontierCode at 28.5 percent and DeepSWE at 77 percent, while Kimi K3 narrowly leads the SWEBench Pro v2 comparison. Kimi K3.1 Pro was not included.<\/p>\n<p>Thinking Machines reports leading results among the compared open-weight models for text recognition, infographic interpretation and visual reasoning. It scores 25.2 percent on the GDP.pdf document benchmark, 81.6 percent on MMMU Pro and 64.7 percent on PerceptionBench. It also earns a 1,340 Elo rating on DesignArena Website, the highest score among open-weight models in that comparison.<\/p>\n<h2>What Does This Mean for Website Audits?<\/h2>\n<p>Inkling 2 Small&#8217;s agentic and visual results may matter when a website depends on a model that can work through a multi-step process, interpret diagrams, read complex PDFs or assess generated web designs. Those capabilities could support analysis of a site&#8217;s content, design assets or technical pages, although the available information does not establish specific improvements to search rankings.<\/p>\n<p>For a site audit, token volume, cost and response behavior are equally important to consider. A model that generates about 150,000 output tokens per task may be expensive for repeated scans, while a 53 percent response rate means some requests may finish without an answer. A practical evaluation should therefore track completion rates, total task cost and the accuracy of visual and document analysis, rather than relying on a general intelligence score alone.<\/p>\n<p>The model&#8217;s strong DesignArena Website rating also gives website owners a useful basis for testing. Because Inkling models are designed for fine-tuning, teams could adapt the model to a particular site or evaluation process. Any such use would still need to account for its tendency to select tools inefficiently, produce cluttered output and perform less effectively in chat.<\/p>\n<h2>What Are the Training and Availability Details?<\/h2>\n<p>Thinking Machines says the complete training run processed about 12 trillion tokens. The reinforcement-learning phase after base training used 3 trillion tokens on 2,048 GPUs over nine days.<\/p>\n<p>The model is initially available through the proprietary Tinker platform. Thinking Machines plans to release the weights under an Apache 2.0 license after external safety testing is complete. It also says more models in the family will be released soon.<\/p>\n<h2>What to Do Now<\/h2>\n<ol>\n<li><strong>Define representative site-audit tasks.<\/strong> Select workflows that reflect your actual work, such as reviewing a complex document, interpreting a visual asset or completing a multi-step page analysis.<\/li>\n<li><strong>Measure cost and token use.<\/strong> Use the reported $1.18 average per task and approximately 150,000 output tokens per task as baseline figures, then test whether similar results hold for your prompts and workflows.<\/li>\n<li><strong>Track unanswered requests.<\/strong> Record the model&#8217;s response rate alongside task accuracy, since its reported 27 percent hallucination rate is partly connected to declining more questions.<\/li>\n<li><strong>Compare visual and coding results.<\/strong> Check performance on the kinds of PDFs, diagrams, interfaces and code that appear in your audits rather than relying on the Artificial Analysis Intelligence Index alone.<\/li>\n<li><strong>Wait for weight availability if deployment matters.<\/strong> Current access runs through Tinker, while the planned Apache 2.0 release depends on external safety testing.<\/li>\n<\/ol>\n<h2>FAQ<\/h2>\n<h3>What Is Inkling 2 Small?<\/h3>\n<p>Inkling 2 Small is a 594-billion-parameter mixture-of-experts model from Thinking Machines with 17 billion parameters active at any given time.
