A powerful but unproven flagship that earns its place for STEM and real-time social data use cases, but the beta tag means it's not yet ready to dethrone Anthropic or OpenAI at this price.
Users who want a frontier-capable model with real-time social context from X and strong STEM reasoning at a mid-range price point.
Real-time integration with X/Twitter data gives it unique access to current events and social context
Strong mathematical and scientific reasoning, competitive with Claude Sonnet 4 on STEM benchmarks
131K context window handles large codebases and lengthy documents well
More willing to engage with edgy or controversial prompts than heavily filtered competitors
Output cost of $15/1M tokens is steep — identical to GPT-4o and pricier than Claude Sonnet 4's $15 output but with less proven reliability
