DeepSeek V4 Pro Gets Updated Weights

Weight refreshes are easy to overlook, but they can materially change production behavior without requiring application-level migration.

• –Developers can access the updated model through AI Gateway’s unified API and routing layer
• –The 1M-token context window remains a strong fit for large repositories and long-running agent tasks
• –The dated model slug improves reproducibility compared with silently changing an unversioned endpoint
• –Teams should rerun coding, tool-use, and regression evaluations before switching production traffic
• –AI Gateway’s provider routing and observability can simplify comparing the refreshed weights against other hosted models
