Claude Haiku vs Gemini Flash
The cheap tier, where the shape of the job matters more than the leaderboard. Gemini 3.7 Flash carries a million-token context and is priced to run constantly, which makes it the better agent workhorse. Haiku 4.5 caps at 200K but stays inside the Claude family, so prompts and tool definitions port cleanly from Sonnet.
