Long Context
Use this when
Users who want a frontier-capable model with real-time social context from X and strong STEM reasoning at a mid-range price point.
Skip this if
You need production-grade stability, strong multimodal capabilities, or are cost-sensitive at scale — Claude Sonnet 4 or Gemini 1.5 Pro offer better value at similar quality.

Model is currently in beta, meaning capabilities and pricing may change. Real-time X data integration depends on xAI's API access policies, which may be subject to change. No image generation support confirmed.
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
Weaknesses
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
Still in beta, meaning inconsistent behavior and potential for regressions compared to stable releases
No native image generation and weaker multimodal capabilities compared to GPT-4o or Gemini 1.5 Pro
Real-world use cases
What people actually use xAI: Grok 3 Beta for.
Analyzing trending X discourse around a product launch for competitive intelligence research
Solving advanced mathematics or physics problems with step-by-step reasoning

Claude 3.5 Sonnet is Anthropic's mid-cycle flagship model, balancing strong reasoning, coding, and instruction-following with a 200K context window. It sits between Haiku and Opus in Anthropic's lineup, offering near-flagship quality at a lower cost than top-tier models.
Verdict
One of the best models for coding and complex instruction-following, but its premium pricing demands premium use cases.

Context
200k tokens
Pricing at $6 input / $30 output per million tokens is significantly higher than GPT-4o ($2.50/$10). Best accessed via Anthropic API or Amazon Bedrock. Claude 3.5 Sonnet (October 2024 version) supersedes the June 2024 release with improved performance.
Claude Opus 4 is Anthropic's most capable flagship model, designed for complex reasoning, nuanced writing, and sophisticated multi-step tasks. It sits at the top of the Claude 4 family, prioritizing depth and quality over speed.
Verdict
Anthropic's best model for when quality matters more than speed or cost.
