Claude Opus 4.7 is now in Vibely
Sharper reasoning, fewer turns, better long-context memory. Here is what changed and how to get the most out of it.
Claude Opus 4.7 with a 1M-token context window is now the default planning model in Vibely. In our internal evals, Opus 4.7 finishes the same tasks in 28% fewer turns than the previous default and recovers from long edit chains far more reliably.
What this unlocks
- Bigger projects, single conversation. 1M tokens means the agent can keep an entire mid-sized codebase in working memory without compaction artifacts.
- Sharper plans. Plan mode now produces concrete file lists and acceptance criteria instead of generic outlines.
- Better self-healing. When a tool call fails, Opus 4.7 reads the error, re-plans, and converges in one or two retries — rarely the full three-attempt cap.
How to choose your model
You do not have to think about this. Vibely picks Opus 4.7 for planning and a faster default for execution turns. If you want full control, the model selector in the composer lets you pin a specific model — useful for long debug sessions where consistency matters more than ceiling.
What did not change
The contract with the agent is the same: one loop, one history, real tools, streaming previews. We tune the model — you keep the workflow.
