For students and solo devs doing text work — flashcards, essays, code, emails — it wins on price by a margin that’s almost embarrassing. That said, if you’re running autonomous terminal pipelines or DevOps agents, GPT-5.5 is a different tier entirely — 91.2% on Terminal-Bench Hard vs DeepSeek’s 61%, and 85% on ARC-AGI-2 which is specifically designed to resist memorization. NotebookLM is solid for document Q&A but it’s locked to your uploads and can’t run custom workflows. Bottom line: DeepSeek V4-Flash for everyday tasks, GPT-5.5 only if you’re building serious agentic pipelines and the price is justified — and no, DeepSeek R2 doesn’t exist yet, the latest is V4-Pro and V4-Flash, released April 24, 2026. submitted by /u/Ok-Drama-6800
