Proveo

Proveo is a Windows desktop app for developers who pay for AI coding help. You provide it with the coding task and the tests. The service first tries the most inexpensive model – Llama 3.2 3B on a Raspberry Pi 5, followed by Qwen3-14B on a PC GPU and Meta Muse Spark 1.3 on the cloud. Each answer gets tested against your tests; the one that first passes your test wins, meaning that you pay for using the cloud-based model only if the other two models fail the tests. Passed answers are memorized and re-tested against your tests the next time around. It also has a monthly budget guard (warning at 80%, cloud skipped at 100%), named encrypted API keys, and a switch to go straight to the cloud. Measured results: 23 of 24 benchmarking tasks completed locally. On 12 held-out tasks, PC to cloud solved 12 out of 12 for $0.00085, while always using the cloud with minimal effort was $0.0116, which is 92.7% cheaper. They are small tasks with just one task each, and the numbers are simulated from tier-based calculations. It can only work on tasks with tests, and it is not a sandbox either.
