Risk and fraud
For chargebacks and disputes, our top pick is MiniMax M3 from MiniMax. Reads text, images, and video with a 1M-token context, so a whole dispute file fits in one run. Kimi K3 is a close second, and GLM-5.3 rounds out the list.
Dispute agents gather delivery proof, order history, customer messages, and screenshots, then assemble an evidence packet before the network deadline. That means mixed inputs, long context, and careful writing.

Turn the steps your team already follows into a skill the agent reads before every run.
Run two or three of these models against past cases. Evals show which one passes at the lowest cost.
The agent works on its own computer in your VPC, with role-based access and an approval before sensitive actions.

Image input for receipts and screenshots. Long context for full order histories. Clear, structured writing for evidence packets. Test two or three candidates against your own past cases before you commit, and keep a human approval on any step that moves money or changes a customer's status.
Yes. Download the weights and serve them with vLLM or SGLang in your own cloud, or use Amazon Bedrock or Google Vertex AI in your account. With Runtime, the agent's computer also runs in your VPC, so card data and PII stay in your environment.
