A discrepancy in how OpenAI and Anthropic account for revenue earned through cloud partners has raised questions about valid comparisons between the two firms and reported growth rates for the broader AI market.[^1]

Claude Haiku 5.5 launched with availability across Amazon Web Services, Google Cloud and Microsoft Azure at release.[^3] Gemini Agent will route tasks between Google Gemini and Anthropic Claude models, selecting providers per task quality and cost suitability.[^4]

On October 6 2026, Desearch released an installable Model Context Protocol server extension for the Gemini CLI.[^2] The protocol establishes connection via an initialise handshake, where the server returns an Mcp-Session-Id header to the connecting client.[^5]
