Cosine

Cosine focuses exclusively on the coding domain with models optimized for production-grade software development. The platform operates on the principle that specialized models outperform generalists—Cosine's architecture is trained on actual codebases and designed to handle the unique challenges developers face.

Highlights

• Multiple deployment options: cloud IDE, terminal CLI, or fully private air-gapped infrastructure
• Support for legacy languages and modern stacks including COBOL, Fortran, Verilog, Rust, and SQL
• Tiered model selection from efficient on-device implementations to frontier-scale reasoning engines
• Free trial with 2 million credits; paid plans from $19/month offering 4M monthly credits upward
• Enterprise deployments with custom infrastructure and security configurations

Ideal for teams handling legacy systems, complex architectures, or requiring air-gapped deployments. Pricing scales from individual developers to enterprise organizations with volume-based credit systems.
