What happened lately

PostHog MCP Leaderboard timeline

PostHog publishes a leaderboard from tool-call events on its own Model Context Protocol server. It separates model usage, client harnesses, tool categories and error rates. The October 15 snapshot covers October 5-11 for its weekly comparisons.

Most model labels are supplied by agents themselves, and some calls have no model label. These observations describe PostHog’s traffic rather than global model adoption or a controlled benchmark. Server-side latency also excludes model thinking and network time.
