Cursor Composer 2.5 becomes the in-IDE default — Build in Parallel + cloud agent dev environments + MS Teams clear the procurement bar

Cursor's Composer 2.5 (May 18 release) matched Opus 4.7 and GPT-5.5 on coding benchmarks at $0.50/M input / $2.50/M output. The new version added cloud agent dev environments, Microsoft Teams integration, and Build in Parallel — concurrent sub-agent execution on the same git working tree. The combination is the strongest model-agnostic in-IDE offer currently available.

Build in Parallel is the engineering substance; the Teams integration is the procurement story. Enterprise buyers on M365 layer Cursor onto existing identity and billing without a parallel SSO setup. For the agent-surface lanes we mapped yesterday, Cursor's defenders argue this is the cleanest defensive position: model-agnostic backend, deepest IDE muscle-memory, and now the broadest enterprise-tool integration.

Against Windsurf 2.0's quota pricing and bundled Devin, the differentiation sharpens. Procurement teams that prefer fixed quotas and bundled autonomous engineers go Windsurf; teams that prefer per-token pricing and model-routing flexibility go Cursor. Both are defensible; neither is a single-vendor lock-in.
