That\u2019s why we\u2019re excited to announce that Anthropic\u2019s Claude Sonnet 4.5, released just hours ago, is already live in GoSearch as a flagship model option.<\/p>\n\n\n\n<p>This powerful new model joins our growing suite of flagship and reasoning LLMs, giving every team the flexibility to choose the best AI for the job, whether you\u2019re running a quick search, building a custom agent, or automating a complex workflow across your tech stack.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>About Claude Sonnet 4.5<\/strong><\/h2>\n\n\n\n<p>Anthropic is calling Claude Sonnet 4.5 <em>the best coding model in the world<\/em>. And for good reason:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Advanced coding capabilities<\/strong> \u2013 Claude Sonnet 4.5 is trained to handle complex software engineering challenges, from writing optimized code to debugging large systems.<br><\/li>\n\n\n\n<li><strong>Strongest model for building agents<\/strong> \u2013 If you\u2019re creating AI-powered agents in GoSearch to automate tasks across apps, Claude 4.5 sets a new standard in reliability and execution.<br><\/li>\n\n\n\n<li><strong>Superior computer use<\/strong> \u2013 Claude Sonnet 4.5 is designed to excel at interacting with tools, applications, and APIs, which makes it especially effective for enterprise automation.<br><\/li>\n\n\n\n<li><strong>Big leaps in reasoning and math<\/strong> \u2013 Alongside coding, Claude 4.5 demonstrates significant improvements in logic-heavy and quantitative tasks, critical for engineering, data science, and finance use cases.<br><\/li>\n<\/ul>\n\n\n\n<p>For technical teams who need an AI that can both understand natural language queries and act across systems, Claude Sonnet 4.5 is a major upgrade.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">C<strong>laude Sonnet 4.5 for Agents<\/strong><\/h2>\n\n\n\n<p>Where Claude Sonnet 4.5 will really shine in GoSearch is in agent building. With no code required, teams can design agents that:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Execute recurring workflows.<br><\/li>\n\n\n\n<li>Act across apps like Jira, Confluence, Slack, GitHub, and more.<br><\/li>\n\n\n\n<li>Perform multi-step reasoning with reliability.<br><\/li>\n<\/ul>\n\n\n\n<p>Because Claude 4.5 is better than ever at using computers, it can handle complex tool calls and longer chains of logic, making it ideal for enterprise-grade automation.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Available in GoSearch the Same Day<\/strong><\/h2>\n\n\n\n<p>One of GoSearch\u2019s core commitments is making sure teams never have to wait to experiment with the latest AI models. As soon as a model is released, we move quickly to integrate it into our platform.<\/p>\n\n\n\n<p>That means on day one, your team can:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Start running <a href=\"https:\/\/www.gosearch.ai\/product\/enterprise-search\" target=\"_blank\" rel=\"noreferrer noopener\">enterprise searches<\/a> with Claude Sonnet 4.5.<br><\/li>\n\n\n\n<li>Power <a href=\"https:\/\/www.gosearch.ai\/product\/ai-workplace-assistant\" target=\"_blank\" rel=\"noreferrer noopener\">GoAI<\/a> responses with improved reasoning and coding strength.<br><\/li>\n\n\n\n<li>Build <a href=\"https:\/\/www.gosearch.ai\/product\/ai-agents\" target=\"_blank\" rel=\"noreferrer noopener\">custom agents<\/a> backed by Anthropic\u2019s most advanced model to date.<br><\/li>\n<\/ul>\n\n\n\n<p>This immediate availability ensures your organization stays ahead of the curve, experimenting with and adopting new AI capabilities as they launch.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The GoSearch LLM Ecosystem<\/strong><\/h2>\n\n\n\n<p>Claude Sonnet 4.5 is joining a robust set of options inside GoSearch. Every query, every conversation, and every agent can be configured with the exact model that fits the task.<\/p>\n\n\n\n<p>Here\u2019s the current lineup:<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Flagship Models<\/strong><\/h3>\n\n\n\n<p>Optimized for general-purpose performance across knowledge, reasoning, and creative tasks.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>GPT-5 (OpenAI)<br><\/li>\n\n\n\n<li>GPT-4.1 (OpenAI)<br><\/li>\n\n\n\n<li>Claude Sonnet 4.5 (Anthropic)<br><\/li>\n\n\n\n<li>Claude Sonnet 4 (Anthropic)<br><\/li>\n\n\n\n<li>Gemini 2.5 Flash (Google DeepMind)<strong><br><\/strong><\/li>\n<\/ul>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Reasoning Models<\/strong><\/h3>\n\n\n\n<p>Specialized for deep thinking, analysis, and step-by-step reasoning.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>GPT-5 Thinking (OpenAI)<br><\/li>\n\n\n\n<li>o4-mini (OpenAI)<br><\/li>\n\n\n\n<li>Claude Sonnet 4.5 Thinking (Anthropic)<br><\/li>\n\n\n\n<li>Claude Sonnet 4 Thinking (Anthropic)<br><\/li>\n\n\n\n<li>Gemini 2.5 Pro (Google DeepMind)<strong><br><\/strong><\/li>\n<\/ul>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>LLM Switching: Choose the Best Model for the Job<\/strong><\/h2>\n\n\n\n<p>One of GoSearch\u2019s most powerful features is per-prompt model selection. Instead of locking your organization into one default LLM, we give you the flexibility to pick the right tool for the task, every time.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>For enterprise search<\/strong>: Want fast, concise answers? Choose Gemini 2.5 Flash. Need deep reasoning over technical documentation? Try GPT-5 Thinking.<br><\/li>\n\n\n\n<li><strong>For building agents<\/strong>: Create a Jira ticket, digest Confluence docs, or summarize meeting notes with Claude Sonnet 4.5, the strongest model for multi-step, tool-driven workflows.<br><\/li>\n\n\n\n<li><strong>For everyday chat<\/strong>: Switch to GPT-4.1 or Claude 4 for balanced performance across knowledge, writing, and creativity.<br><\/li>\n<\/ul>\n\n\n\n<p>This flexibility extends to custom agents, too. When you build a personal or team agent in GoSearch, you decide which model powers it. That means your finance agent can be driven by a reasoning-heavy LLM while your support ticketing agent runs on a faster flagship model, optimized for both accuracy and efficiency.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Flexible Models for Every Task<\/strong><\/h2>\n\n\n\n<p>In fast-moving organizations, no single AI model can cover every need equally well. Developers want a model that codes. Analysts want one that reasons. Customer-facing teams need one that answers quickly and clearly.<\/p>\n\n\n\n<p>GoSearch is the only enterprise search and AI agent platform that lets you:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Switch models instantly<\/strong> without leaving the dashboard.<br><\/li>\n\n\n\n<li><strong>Mix and match models<\/strong> across teams and workflows.<br><\/li>\n\n\n\n<li><strong>Upgrade to new models immediately<\/strong> as they\u2019re released.<br><\/li>\n<\/ul>\n\n\n\n<p>This ensures your teams aren\u2019t stuck waiting for the \u201cright\u201d AI tool. They can choose it themselves, every time.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Staying Ahead with GoSearch<\/strong><\/h2>\n\n\n\n<p>The AI model landscape is moving faster than ever. What\u2019s cutting-edge today will be outpaced tomorrow. But with GoSearch, your team doesn\u2019t need to worry about falling behind.<\/p>\n\n\n\n<p>We integrate every major LLM release on day one, whether it\u2019s from OpenAI, Anthropic, or Google DeepMind, so your teams always have the latest technology at their fingertips.<\/p>\n\n\n\n<p>And because model switching is built into the core of GoSearch, these comparisons are as simple as changing a dropdown.<\/p>\n\n\n\n<p>Claude Sonnet 4.5 sets a new benchmark for coding, reasoning, and agent building. By making it available in GoSearch the very same day it launched, we\u2019re continuing our mission to keep your teams at the forefront of AI adoption.<\/p>\n\n\n\n<p>The strongest coding and
