Cognition brings Fusion to Devin Desktop and CLI
Teams can test multi-model coding without building a router, but reported savings vary by task and do not prove lower accepted-change cost on their repositories.

Cognition SWE-2, explained.
Cognition SWE-2 is designed for cost-aware agentic coding as a standalone devin model or the execution sidekick in devin fusion. HubAI treats it as a workflow purchase rather than a novelty: the relevant question is whether it produces an acceptable result repeatedly, with controls your team can understand and a cost that remains predictable after the trial ends.

Cost reality
The subscription price is only the starting point. HubAI evaluates usage limits, failed attempts and the work needed to produce one usable result. Pricing changes frequently, so the structure and verification date matter more than a headline price.
Budget for the result, not the plan badge.

A safer four-step trial
- Start with one narrow job that matches Cognition SWE-2's strongest use case.
- Prepare approved source material, examples and a clear acceptance standard.
- Run three realistic tasks and record attempts, correction time and export quality.
- Keep human approval before publishing, sending or acting on the result.
Start with a better brief.
01
Act as a specialist in model ai. Ask me three questions before creating the first draft. The outcome I need is: [describe outcome].02
Create two approaches for [task]. Use this audience: [audience]. Respect these constraints: [constraints]. Explain the trade-off between the two approaches.03
Review this output against accuracy, tone, privacy, cost and usability. List the changes required before a person should approve it.RISK & GOVERNANCE
What to check before adoption.
Do not place confidential, personal or rights-restricted material into Cognition SWE-2 until your organisation has reviewed its current terms, retention settings and account controls. AI output can be plausible and still wrong; regulated, financial, legal and employment decisions require qualified human review.
