Claude Opus 4 and Sonnet 4 are state of the art coding models. They're a leap forward in complex codebase understanding, and we expect developers will experience across the board capability improvements.
Anthropic has again set the gold standard for code-generation models with Claude Opus 4 and Sonnet 4. With a modest shift in prompting, we've seen the new models deliver cleaner, more precise high-quality output.
Claude Opus 4 pushes the envelope once again on coding capabilities, handling complex multi-file changes without touching code you didn’t ask to modify. The improved precision in instruction following plus thinking mode gains show real potential to fundamentally change how Replit Agent works.
Claude Opus 4 is the first model that boosts code quality during editing and debugging in its agent, codename goose, without sacrificing performance or reliability.
Claude Sonnet 4 has soared in agentic scenarios and we’re excited to introduce it as the base model for the new coding agent in GitHub Copilot. In early internal evaluations, the model demonstrated up to 10% improvement over the previous Sonnet generation, driven by adaptive tool use, precise instruction-following, and strong coding instincts.
Claude Opus 4 excels at solving complex challenges that other models can’t. It successfully handles critical actions that previous models have missed—that kind of reliability is transformative for our development workflows.
Claude Sonnet 4 surpasses Sonnet 3.7 with higher success rates, more surgical code edits, and more tightly scoped changes. It works more carefully through complex tasks and delivers superior code quality—making it the ideal choice as the primary coding model in Augment Code.
Against our in-house benchmark, Claude Opus 4 was a dramatic improvement in code generation abilities compared to Anthropic’s previous models. We're incredibly excited to see such progress, and for the product opportunities this unlocks.
Claude Sonnet 4’s code quality is incredible—it stays on track longer, understands problems deeply, and creates elegant solutions instead of brute-forcing fixes. This shows promise to be a substantial leap in software development!
