Google Releases Gemini 3.8 Flash Models

Google's Gemini 3.8 Flash announcement adds a developer-facing model and pricing signal: reported introductory API pricing is $0.75/$3.75 per million input/output tokens, alongside long-horizon coding improvements and a lower-effort mode. Managed-agent access adds sandboxes, tools, MCP, persistence, and background execution, while Mantis supplies an open-source vulnerability-validation workflow; benchmark, availability, and performance claims require validation.
