Code Smarter with Qwen3-Coder on Together AI's frontier AI cloudStarting today on Together AI, you can access Qwen3-Coder-480B-A35B-Instruct from the Qwen herd — the most capable agentic coding model available. Unlike traditional coding assistants that excel at individual functions but struggle with complex workflows, Qwen3-Coder delivers frontier-level performance on the messy, interconnected work that defines real software engineering.SummaryMost capable agentic coding model: 480B parameters with 256K context natively (1M with extrapolation)Frontier performance: State-of-the-art SWE-bench Verified results, comparable to Claude Sonnet 4Production-ready deployment: Together AI's optimized infrastructure makes massive models instantly accessibleReal engineering workflows: Handles entire codebases, not just isolated code snippetsPerformance That Actually Matters 📊 Benchmark 🤖 Qwen3-Coder 🏛️ Claude Sonnet 4 📈 Other Open Models 🔧 SWE-bench Verified 69.6% 70.4% ~40-50% 🎯 Agentic Coding 37.5 39.0 ~25-30 🌐 Agentic Browser Use 49.9 47.4 ~35-40 🛠️ Agentic Tool Use 68.7 65.2 ~45-55 🚀 Qwen3-Coder achieves frontier-level performance on complex autonomous workflows.These aren't toy benchmarks — they represent the messy, interconnected engineering work that traditional coding models can't handle. Together AI's continuous optimizations mean these capabilities improve over time without requiring any migration work on your end.Why This Changes Everything for Development TeamsMost coding models hit the same wall when faced with real engineering work. They can write clean functions in isolation, but ask them to refactor a legacy system or implement a feature spanning multiple services, and they fall apart.The breakthrough: Qwen3-Coder can hold your entire codebase in working memory while autonomously executing complex engineering workflows. Need to modernize authentication across a microservices architecture? It understands the database schema, API contracts, frontend implications, test requirements, and deployment considerations — all simultaneously.What makes this possible on Together AI is our infrastructure built ground-up for AI workloads, not retrofitted from general cloud services. This architectural advantage means deploying a 480B parameter model becomes as simple as calling a standard API.⚡Massive Scale480B total35B active parametersMoE efficiency🧠Advanced Training7.5T tokens70% code ratioComplex RL workflows🚀Production ReadyZero setupInstant deployment4x faster inferenceReal Engineering ApplicationsQwen3-Coder excels at the complex tasks that define modern software development:🔄 Legacy System ModernizationComprehensive analysis, security vulnerability identification, migration planning, and implementation across multiple services while maintaining backward compatibility. Perfect for OAuth migrations, framework upgrades, and architectural refactoring.⚙️ Cross-System Feature DevelopmentEnd-to-end implementation spanning backend APIs, frontend components, database changes, and deployment pipelines with proper error handling. Handles rate limiting, payment integrations, and multi-tenant features that touch every part of your stack.🔍 Complex Debugging & Root Cause AnalysisDistributed system issue investigation, understanding failure propagation, and implementing systematic fixes that address underlying problems. Traces issues across microservices, identifies performance bottlenecks, and suggests architectural improvements.Deploy on Together AI's Optimized InfrastructureDeploying a 480-billion parameter model for production development workflows presents real challenges. Most cloud providers force impossible tradeoffs between performance, reliability, and cost. Together AI's infrastructure eliminates these compromises entirely.🚀PerformanceResearch-driven optimizationsCustom kernels & scaling⚡Reliability99.9% uptime SLAMulti-region deployment🔒SecuritySOC 2 compliantNorth American infrastructureOur platform delivers native AI performance through custom optimizations specifically designed for large language models.
