Nothing visible gates the table itself.\n\n**Details**\n\n- A separate group covering `claude-sonnet-4-6`, `claude-opus-4-6`, `claude-opus-4-8` and `claude-opus-5` is used for a capability check whose consumers are not settled by this code.\n\n**Evidence**\n\n`remote_cowork`\n\n- Area: Models\n- Tier: Under the hood\n- Useful: 3\/5\n- Signal: 4\/5"}
