Both Claude Opus 4.8 and GPT-5.5 now offer one-million-token context windows via their APIs – enough for most complex commercial broking tasks. A standard commercial property policy wording runs to roughly 50,000 to 100,000 tokens; a complete renewal pack including submission, prior year policy and claims schedule might reach 200,000 to 400,000. The context window determines whether you can load all of that at once – or whether you need to break it into chunks and lose the whole-picture view that makes AI genuinely useful for complex placements.
