What is Windsurf?
Windsurf is folding Devin into every surface — IDE, terminal, and a new local agent.
Windsurf, Cognition's AI IDE, is mid-merge with Devin. The 2.0 launch put Devin Cloud inside the editor; the late-April releases pushed further: Devin for Terminal (a Rust-written multi-model CLI agent shipped to all subscribers), a new Devin Local agent harness inside Windsurf claimed to be 30% more token-efficient than the original Cascade agent, and now Devin Review & Quick Review tooling. Frontier-model coverage is being kept current — GPT-5.5 and Claude Opus 4.7 both landed in April. The Agent Command Center continues to mature with kanban views, Spaces, and inbox refinements.
What is Depot?
Depot turns its build-acceleration compute into a metered backend for AI agents.
Depot is shipping fast across two fronts: hardening its CI platform and opening its compute to AI workloads. Recent CI work includes native step retries, durable cache disks, and a generally available API and CLI with full dashboard parity. On the AI front it added SOCI v2 to cut startup time for large CUDA and PyTorch images and launched a Sandbox SDK to run untrusted or agent-generated code in ephemeral, billed sandboxes.

Windsurf is folding Devin into every surface — IDE, terminal, and a new local agent.
◆ Current state
Windsurf, Cognition's AI IDE, is mid-merge with Devin. The 2.0 launch put Devin Cloud inside the editor; the late-April releases pushed further: Devin for Terminal (a Rust-written multi-model CLI agent shipped to all subscribers), a new Devin Local agent harness inside Windsurf claimed to be 30% more token-efficient than the original Cascade agent, and now Devin Review & Quick Review tooling. Frontier-model coverage is being kept current — GPT-5.5 and Claude Opus 4.7 both landed in April. The Agent Command Center continues to mature with kanban views, Spaces, and inbox refinements.
◆ Where it's heading
Cognition is consolidating Devin and Windsurf into a single agent stack with three entry points: terminal, IDE, and cloud VM. The same agent harness now powers all three. Strategic direction is clear — Cascade, the original Windsurf agent, is being phased out in favor of the Devin harness that's measurably cheaper per token. Frontier-model neutrality (Opus 4.7, GPT-5.5, SWE-1.6 all named) keeps Windsurf positioned as a multi-model client even as Anthropic and OpenAI push their own coding products.
◆ Prediction
Expect a Cascade-to-Devin migration to be made automatic or default in the next minor — the team won't run two agent harnesses in parallel forever once one is meaningfully more efficient. The Devin Review tooling shipped this week likely expands into PR-level review on GitHub directly, since Cognition has both the Devin Cloud infrastructure and the IDE relationship to wire that up.
Depot
7.5INFRA · APIS
Depot turns its build-acceleration compute into a metered backend for AI agents.
◆ Current state
Depot is shipping fast across two fronts: hardening its CI platform and opening its compute to AI workloads. Recent CI work includes native step retries, durable cache disks, and a generally available API and CLI with full dashboard parity. On the AI front it added SOCI v2 to cut startup time for large CUDA and PyTorch images and launched a Sandbox SDK to run untrusted or agent-generated code in ephemeral, billed sandboxes.
◆ Where it's heading
Depot is extending from build and CI acceleration toward being a general compute backend for agents. The Sandbox SDK, the agent-friendly GA API, and ML-image startup optimizations point the same way: sell fast, isolated, metered compute that AI tools and pipelines can drive programmatically. The CI improvements keep the core product sticky while the platform broadens.
◆ Prediction
Expect the Sandbox SDK to move toward general availability with more language and filesystem surface, and continued convergence of CI and sandbox compute under one metered, API-first platform.
