# Why Magnitude

> The best coding agent for open models

Magnitude is the best coding agent for open models. We don't just run them. We optimize the entire agent stack to get the most out of them:

* **Tool call reliability:** malformed tool calls are impossible, prevented at the provider level.
* **Overthinking fixes:** guardrails prevent open models from getting stuck in reasoning loops.
* **Context management:** efficient prefix cache management results in a 97.2% cache hit rate.
* **Continuous tuning:** we constantly test new model setups and update configurations as better options become available

On Terminal-Bench 2.1, Magnitude scores **75.5%**, just 3.4 points behind Claude Code on Opus 4.8 (78.9%), at **one-third the cost** per success. See [Benchmark](/benchmark) for full results.

## Run it in your environment

We can host Magnitude in your VPC or data center. Your code never goes to Anthropic, OpenAI, or anyone else. SSO, RBAC, spend controls, and audit logs included. [Speak with our founder →](https://calendly.com/tom-magnitude/30min)
