Open-Source Model for Agentic Coding👨‍💻

AI is leveling up—fast. From smarter code to stunning game art and powerful generalist agents, 2025 is the year open-source breaks barriers.

Devstral redefines coding with 24B params, 128k context, and 46.8% on SWE-Bench. Built for agentic workflows, it outperforms GPT-4.1-mini and runs on RTX 4090 or 32GB Macs—fast, local, open.

Tencent Hunyuan Game turbocharges game dev with real-time sketching, multi-angle asset previews, and zero-touch rigging—delivering top-tier game art up to 10x faster.

II-Agent brings a fully open, modular AI assistant for research, code, automation, and planning—powered by Claude 3.7 Sonnet and packed with tools for web, PDF, audio, and more.

Smarter tools. Faster workflows. Open-source is no longer catching up—it’s leading.

High-Performance Open-Source Code Assistant

Devstral, a state-of-the-art open-source LLM for software engineering developed by Mistral AI and All Hands AI, addresses real-world coding challenges by contextualizing code across large codebases, identifying component relationships, and detecting subtle bugs. With 24 billion parameters and a 128k-token context window, it achieves a 46.8% score on SWE-Bench Verified—outperforming prior open-source models by 6% and surpassing proprietary models like GPT-4.1-mini by over 20%. Designed for agentic workflows via scaffolds like OpenHands, it runs efficiently on consumer hardware (e.g., RTX 4090 GPUs or 32GB RAM Macs) and is Apache 2.0-licensed for commercial use. Available via API ($0.1/M input, $0.3/M output tokens) and platforms like Hugging Face, Devstral enables privacy-focused enterprise deployments and local IDE integrations while avoiding full-file rewrites to reduce errors.

Powered by Hunyuan AI, it offers a streamlined AI art pipeline that takes users from inspiration to design and multi-view previews within a single, optimized workspace. Key features include a real-time canvas for live sketching and instant AI-powered refinement, a 2D generator with text and image tools tailored for game concepts and UI, and automated character orthographic views that deliver studio-quality multi-angle and 360° previews ready for rigging without further edits. With Hunyuan Game, developers and artists can accelerate their workflow and elevate the quality of game assets, making it a cutting-edge solution for the future of game art production.

II-Agent: Open-Source Generalist AI Assistant

II-Agent is an open-source intelligent assistant framework introduced in 2025 as part of the broader Intelligent Internet system, designed to provide transparent, auditable, and high-performing AI agents for a wide range of domains. Built to rival leading closed-source agents like Manus and GenSpark, II-Agent leverages advanced large language models (such as Claude 3.7 Sonnet) and a robust function-calling architecture to deliver capabilities in research, content creation, data analysis, software development, workflow automation, and problem-solving. Its core features include multistep web search, structured note-taking, code synthesis, browser and file system automation, and advanced planning and reflection tools. II-Agent manages complex interactions with intelligent context management and supports extensibility with specialized tools for tasks like PDF extraction, audio transcription, and image or video generation. Designed for both individual and enterprise use, II-Agent aims to increase productivity, transparency, and alignment in regulated industries and everyday workflows, offering a powerful, open alternative to proprietary AI assistants.
