Our Verdict
Pick DeepSeek for one reason above all: Free web chat with strong coding and math performance. Pick Grok instead if this matters more: Real-time access to X posts makes it strong on breaking news and trends. Both are freemium, so price is unlikely to decide it. The trade-offs are real on both sides, so weigh DeepSeek's limits against Grok's before committing.
