Cosine, a UK-based company founded in 2022, built its flagship product Genie around a specific training approach: rather than learning primarily from public code repositories, it trained on data capturing how experienced engineers actually work through real tickets, debugging, tracing a root cause, deciding on a fix, aiming for reasoning closer to a senior developer's process than pattern-matching against public code alone.
That approach targets a specific job: taking an existing ticket or bug report and autonomously producing a working fix as a pull request, with enough context-gathering to understand why a bug happens before proposing a change, rather than generating plausible-looking code from a short prompt. It's built for teams that want autonomous resolution of well-defined, existing engineering work.
There's no free tier; pricing starts around $20 a month. For an engineering team with a backlog of tickets and bug reports that wants an agent trained specifically on realistic problem-solving processes rather than general code generation, Cosine's Genie targets that ticket-to-fix workflow directly.
