# Multi Policy Solver and Verifier

> Two policies in one run — a solver answering gsm8k, and a verifier scored on ruling correctly about the solver's answers.

Two policies trained against each other in one run: a solver answering a gsm8k question and a
verifier ruling on its work. Each rollout yields one sample per policy; each policy has its own
trainer and its own inference engines inside the same job.

## Quick Start

Eight GPUs: 2 trainer GPUs and 2 single-GPU engines per policy. Needs a cluster backend and a
namespace, from `MILES_SCRIPT_CLUSTER_BACKEND` / `MILES_SCRIPT_NAMESPACE` or `--cluster-backend` /
`--namespace`:

```bash theme={null}
python examples/multi_policy/run_solver_verifier_gsm8k.py
```
