With what Claude Opus 5.5 combine
Quick code edits with a second check
One system makes the change, another looks for blind spots, and tests decide.
A second model will not help if both receive the same incorrect assumption without evidence.Documents → analysis → verification
A fast model prepares the material, and a stronger model focuses on analyzing it.
Agreement between two models is not proof; the cited inputs are what matters.Sensitive data under your own control
The sensitive part stays on your own server, and the online service receives only the necessary data.
First, check the license for your intended use. Being able to run a model yourself does not in itself guarantee privacy. Server security and what data is stored also matter.Trends over time

Claude Opus 5.5 available on Amazon Bedrock with lower costs per task
According to Anthropic, developers working with long-running agentic tasks or extensive documents can expect clearer ongoing updates on model progress and less need to correct outputs, but also more frequent refusals of requests due to stricter safety classifiers.
According to Anthropic, companies running agentic tasks on Amazon Bedrock may achieve lower average costs per task thanks to lower token prices and significantly cheaper cache reads, which is particularly relevant for long-running and repeated workloads.
GitHub recommends Claude Opus 5.5 following the retirement of Claude Opus 4.7
New: The recommended replacement for Claude Opus 4.7 is Claude Opus 5.5, not Claude Opus 5.
When switching from Claude Opus 4.7, follow the current recommendation to use Claude Opus 5.5; the earlier announcement listed a different replacement.
Migrating company workflows and integrations to supported models may require enabling replacement models through access policies in Copilot Enterprise or Copilot Business.
The Claude Opus 5.5 model is available in GitHub Copilot
Users on Copilot Pro+, Max, Business and Enterprise plans can select the Claude Opus 5.5 model in the model picker for agentic coding and long-running tasks once the gradual rollout reaches them.
Companies with Copilot Business or Enterprise can make the model available to teams through model policy; with usage-based billing, fewer steps and tokens for comparable tasks may mean lower costs for agentic tasks, according to Anthropic.
