GitHub rolls out GPT-5 mini and GPT-4.1 fashions to Copilot CLI alongside 4 specialised brokers for code evaluation, planning, and automatic testing.
GitHub has shipped a considerable replace to Copilot CLI, including GPT-5 mini and GPT-4.1 fashions that will not depend in opposition to premium request limits for paid subscribers. The January 14 launch additionally introduces 4 specialised brokers designed to deal with discrete improvement duties with out cluttering your major dialog context.
The brand new brokers—Discover, Process, Plan, and Code-review—every sort out particular workflows. Discover handles quick codebase evaluation for fast questions. Process runs builds and checks, returning transient summaries on success however full output when issues break. Plan maps out implementation by analyzing dependencies. Code-review focuses on surfacing real points moderately than nitpicking fashion preferences.
What’s really helpful right here: Copilot now delegates to those brokers routinely when it detects an applicable process, and may run a number of brokers in parallel. Mixed with the Agent Expertise function GitHub launched in December, builders can chain agentic workflows straight from their terminal.
Set up Will get Easier
GitHub has added bundle supervisor help throughout platforms. Home windows customers can run winget set up GitHub.Copilot, whereas macOS and Linux customers have Homebrew (brew set up copilot-cli) or a curl script possibility. Bundle supervisor installations deal with automated updates—no extra handbook model bumps.
The CLI now comes pre-installed in GitHub Codespaces and works as a Dev Container Function for standardized dev environments.
Context Administration Enhancements
Token administration will get smarter with auto-compaction that kicks in at 95% of the restrict, routinely compressing dialog historical past. The brand new /context command exhibits precisely the place your tokens are going, whereas /compact helps you to manually compress when wanted.
Session continuity improves too—the --resume flag now helps you to tab by each native periods and distant Copilot coding agent periods.
Pipeline Integration
New flags goal CI/CD use instances. --silent suppresses logs for clear parseable output. --share-gist exports periods to shareable gists. Software allowlisting and denylisting by way of --available-tools and --excluded-tools give granular management over what Copilot can entry in automated environments.
A brand new web_fetch instrument retrieves URL content material as markdown, with entry managed by config file patterns that additionally apply to shell instructions like curl and wget.
The diff viewer now contains intra-line syntax highlighting and integrates with Git’s configured pager. Agent-run instructions now not pollute your bash historical past—a small quality-of-life repair that issues throughout lengthy debugging periods.
Replace by way of your bundle supervisor or run npm set up -g @github/copilot@newest. The general public repository at github.com/github/copilot-cli hosts ongoing dialogue.
