About GitHub Copilot

GitHub Copilot combines inline coding assistance with chat, planning, local agents and asynchronous cloud-agent workflows. It can help developers understand repositories, implement features, generate tests and review pull requests. Supported IDEs, Copilot CLI, the desktop app and SDK offer different tools and controls; feature access depends on the plan and organization policies. Local BYOK models and execution are available in supported clients, while the managed service remains cloud based. Belliste has not independently benchmarked coding performance. Official documentation was reviewed on October 19, 2026.

Supported Operating Systems	CLI: Linux, macOS and Windows through PowerShell or WSL. IDE and desktop availability depend on the client.
Supported IDEs & Editors	VS Code, Visual Studio, JetBrains IDEs, Eclipse and Xcode; Vim/Neovim completion integration is also listed by GitHub. Feature coverage varies.
Programming Languages	Broad programming-language support. Quality varies by language and training-data coverage; no equal-capability guarantee.
Framework Support	Assists across many frameworks using source context and project tooling; an exhaustive framework compatibility guarantee is not disclosed.

Code Completion	Inline completions and next edit suggestions in supported editors. Free: 2,000 completions/month; paid completions are unlimited, subject to rate limits.
Code Generation	Generates functions, implementation code and application changes from prompts; agents can write files and iterate.
Inline Code Editing	Inline chat and suggested edits in supported editors; users can accept proposed changes. Availability depends on IDE.
Multi-File Editing	Agents can coordinate changes across project files; review diffs before keeping or merging changes.
Code Explanation	Explains selected code, project behavior and coding concepts through chat with repository context.
Refactoring	Can propose or apply targeted refactors through chat and agents; correctness depends on project context and validation.
Debugging Assistance	Suggests fixes and investigates failures using source context and available tools; command execution requires an agent-capable surface.
Test Generation	Generates unit tests and additional test suites from code or feature requirements.
Documentation Generation	Can create or update README files, code comments and project documentation through prompts and agent workflows.
Code Review	Copilot code review produces pull-request feedback and suggested changes. Paid-plan access, organization policies and usage charges apply.
Image-to-Code	Image-capable chat models can turn UI mockups or web-page screenshots into code. Supported attachments and model access vary by client and plan.

Agent Mode & Planning	Ask, Agent and Plan modes in supported IDEs; CLI has planning and execution modes. Administrators can restrict agents.
Terminal Command Execution	CLI and supported IDE agents can execute shell commands with permission controls; cloud agent runs commands in its environment.
Automated Test Execution	Agents can run project tests and linters when the environment and dependencies are configured; generated tests do not imply successful execution.
Browser Interaction	Copilot app connects browser workflows; optional computer use in local CLI/app sessions can interact with desktop applications on macOS and Windows. Tools and permissions must be enabled.
Background / Cloud Agents	Paid plans include asynchronous Copilot cloud agent for repository tasks and pull requests. Cloud sandboxes for CLI are public preview.
Parallel Agent Tasks	Copilot app manages parallel sessions and repository workstreams; CLI cloud sandboxes support multiple parallel tasks. Capacity depends on available resources and usage.
Human Approval Controls	CLI asks approval for tools that modify or execute files, with session allow/deny options. Agent changes and pull requests remain reviewable; policies vary by surface.
Execution Isolation / Sandbox	Cloud agent uses an ephemeral firewalled environment with security scans. CLI offers optional local sandboxing and isolated cloud sandboxes; local trust permissions alone are not a sandbox.
Execution Environment	Local and cloud execution. Hosted-model requests are processed remotely unless a supported local BYOK configuration is used.

Supported AI Models	Model catalog includes GPT-6.1 Sol, GPT-6 Astra/Sol/Luna, Claude Opus 5.5/Sonnet 5.5/Fable 5.1, Gemini 4 Argon, Grok 4.7 and Kimi K3, among others. Access varies by plan, client and policy.
Model Selection	Automatic selection and manual model choice on eligible plans/surfaces. Free and Student use Auto; code review does not offer model switching.
Bring Your Own API Key	Local BYOK in supported clients including VS Code, JetBrains, Xcode, CLI, app and SDK. Enterprise BYOK is public preview and requires licensing and enabled policies.
Local Model Support	Supported through compatible local BYOK providers; CLI documents Ollama/vLLM-compatible endpoints. CLI models must support tool calling and streaming.
Codebase Context & Indexing	Uses editor/project context and repository information to answer questions and edit files. Indexing and retrieval behavior vary by surface; context access follows permissions and exclusions.
Context Window	Depends on model and client. Selected models offer an optional 1 million-token context in VS Code and Copilot CLI; larger context consumes more AI credits.
Custom Instructions / Rules	Repository custom instructions, reusable prompts, agent skills and custom agents can guide supported workflows; CLI combines applicable instruction files.
Persistent Project Memory	Copilot Memory: public preview for all paid plans, used by cloud agent, code review, CLI and agentic autofix. Stores repository facts and personal preferences; unused entries expire after 28 days.

Git & Pull Requests	Git-aware CLI workflows and native GitHub issues/pull requests; cloud agent can create branches and PRs and revise changes after feedback.
MCP & External Integrations	MCP servers extend supported clients and SDK with external tools and context. Availability and administrative controls vary by client and organization policy.
Web Search	Copilot Chat can use Bing web search when enabled; disabled by default in personal settings. Supported IDE workflows expose web search through GitHub skills.
API / SDK Access	Copilot SDK exposes agent sessions, streaming, tools, hooks, custom agents and MCP through the CLI runtime. Programmatic CLI and ACP integrations are also documented.
Deployment Support	Can generate deployment configuration and run permitted deployment tools or GitHub Actions workflows. Hosting is provided by the selected external platform; Copilot is not a standalone managed deployment service.

Free Plan / Trial	Free plan available with 2,000 monthly completions and limited other usage. Student eligibility and free Pro access for eligible teachers/maintainers have separate conditions. A universal current trial duration is not disclosed on reviewed pricing pages.
Usage Limits / Extra Usage	Monthly included AI credits: Pro 1,500 (1,000 base + 500 flex), Pro+ 7,000 (3,900 + 3,100), Max 20,000 (10,000 + 10,000). Flex amounts can change. Business 1,900/seat and Enterprise 3,900/seat pool across licensed users; extra usage $0.01/credit. Token/model consumption and rate limits apply; Actions usage can add charges.
Team Administration	Business and Enterprise provide managed seats, policies, usage oversight and organization/enterprise controls. Business $19/seat/month; Enterprise $39/seat/month and requires GitHub Enterprise Cloud.
Code Privacy & Data Retention	Hosted requests use GitHub/model-provider infrastructure. Individual Free/Pro/Pro+/Max interactions may train models unless opted out; Business/Enterprise data is not used for training. Business/Enterprise default IDE Chat/completion prompts are not retained; other access retains them for 28 days, with engagement data kept two years. Model-specific retention exceptions and BYOK provider policies apply.
