Cosine

What is Cosine?
Cosine ships the Lumen family of coding models and a developer workspace for teams that want AI close to their repos. You can start in a terminal-native flow with MCP tool access and multi-agent orchestration, or run parallel cloud tasks when PMs and engineers need a shared project view.
General chat models spread training across poetry and trivia; Cosine bets the opposite with Lumen models post-trained on production code from real engineering teams. Lumen Outpost scored 59.3% on Niche-Bench in Cosine's published comparisons, ahead of GPT-5.4 at 42.4%, and the lineup adds Scout for cheap codebase mapping plus a forthcoming Sovereign tier for controlled environments.
Developer teams, platform engineers, and regulated orgs use Cosine when they need deployment choice from public cloud to managed single-tenant or fully air-gapped installs. Pricing starts at $19 per month for 4M credits on the Starter plan, with Team and Enterprise tiers scaling credits and lowering per-million add-on rates.
AskUI

What is AskUI?
AskUI lets delivery teams automate real devices in plain English. You write a task as a Markdown file in Git, an AI agent runs it on desktop, web, mobile, or hardware displays, and returns a verdict plus a screenshot for every step.
Traditional test automation depends on DOM selectors and brittle scripts that break when UIs change. AskUI tests what is rendered on screen, including canvas apps, Citrix sessions, and QNX HMIs controlled through HDMI capture with nothing installed on the target. The trade-off is sales-led pricing quoted per concurrent agent after a scoping call, not self-serve monthly plans.
QA teams replace manual regression on legacy SAP portals and vendor RFQ systems. Automotive manufacturers run HMI regression across infotainment fleets. Operations teams generate audit evidence with screenshot-backed run reports from scheduled agent jobs.
