Estimated Belliste score, based on the available capabilities, quality, features and pricing information. It is an indicative profile estimate, not an independent benchmark.

How this profile estimate is calculated

Capabilities contribute 35%, quality wording 30%, listed features 20%, and pricing 15% when available. When capability fields are absent, specialization breadth supplies a 25% fallback. Missing categories are omitted and the remaining weights are rescaled. The estimate uses each model’s own published profile; it does not measure answer accuracy or replace a hands-on test.

Code CompletionCursor Tab provides as-you-type code suggestions, multi-line edits and next-edit predictions. Availability and limits depend on the current plan.Traditional as-you-type inline code autocomplete: Not disclosed. Codex documents prompted coding, editor-context input and diff review.

Code GenerationAgent creates and edits code files from natural-language instructions using project context.Generates code and files from instructions in an existing repository or new project.

Inline Code EditingSelect code and use Cmd/Ctrl+K for a targeted edit in place; follow-up instructions refine the selected change.Uses selected editor code and open files as context for requested changes; edits can be reviewed beside the source.

Multi-File EditingAgent coordinates edits across files; selected inline-edit context can be handed to Agent for larger changes.Can change multiple files in one repository task and present the resulting diff for review.

Code ExplanationAsk Agent about repository code, or use inline question mode on a selected block.Explains repository structure, functions and unfamiliar implementation details using accessible files.

RefactoringCan restructure selected code or perform repository-wide refactoring; checkpoints support restoring file changes.Refactors existing code using project instructions and can verify the result with available checks.

Debugging AssistanceDebug Mode instruments code, guides reproduction, analyzes runtime logs and proposes a targeted fix, followed by verification and cleanup.Investigates error reports, traces code paths and implements fixes; available logs and tests improve verification.

Test GenerationAgent can write tests for requested behavior using the repository’s testing framework and accessible source files.

Agents & Execution

9 specifications

SpecificationCursorOpenAI Codex

Agent Mode & PlanningAgent can execute multi-step tasks; Plan Mode supports researching a change and reviewing the implementation plan before building.Agent can inspect, plan, edit and verify a task. Planning and execution follow the selected mode and permission policy.

Terminal Command ExecutionRuns terminal commands and monitors output. Run Modes, allowlists and sandbox policy determine execution and approval behavior.Runs shell commands, builds and installed development tools within the allowed filesystem and network scope.

Automated Test ExecutionCan invoke installed tests and build tools, inspect failures and iterate on changes; dependencies and test infrastructure must be available.Runs available test suites, reads failures and can iterate on fixes; dependencies and test infrastructure must be configured.

Browser InteractionIntegrated browser tools navigate pages, interact with UI, capture screenshots and help test applications or verify visual changes.Built-in interactive browser in the desktop app for sites and local previews. It is not built into Codex CLI or IDE extension; browser tools can be added separately where supported.

Background / Cloud AgentsCloud Agents run remotely and can be followed from web/mobile; current new-plan access starts at Premium. Local background work depends on its host.Cloud tasks run in isolated workspaces and continue while the local computer sleeps. Local background work depends on the host remaining available.

Parallel Agent TasksSupports concurrent subagents and background workstreams; cloud subagents can use separate VMs and branches while the parent continues.Supports parallel subagents and separate concurrent tasks; Git worktrees help isolate repository changes. Parallel work increases usage.

Human Approval ControlsAuto-review, Allowlist and Run Everything modes control tool autonomy. Configurable approval policies and team rules apply to shell, MCP and Fetch calls.
