Key differences

How Claude 4.7 Opus and Grok 3 Mini differ

What the numbers mean in practice when choosing between Claude 4.7 Opus and Grok 3 Mini.

  • Grok 3 Mini is 94% cheaper on input tokens ($0.3 vs $5 per million), which adds up quickly in document-heavy workloads.

  • Grok 3 Mini is 98% cheaper on output tokens ($0.5 vs $25 per million) - the bigger factor for tools that generate long documents.

  • Claude 4.7 Opus's 1M tokens context window is roughly 7.6x larger than Grok 3 Mini's 131.1K tokens, so it can work across bigger codebases, contracts, or archives in one pass.

Strengths side by side

Where each model shines, according to benchmarks and provider positioning.

Claude 4.7 Opus

1. State-of-the-art software engineering

  • A notable upgrade over Opus 4.6 on the hardest coding tasks, with users reporting they can hand off work that previously required close supervision.
  • Early partners reported double-digit gains on real-world benchmarks - e.g., Cursor saw CursorBench jump from 58% to 70%, and Rakuten-SWE-Bench resolution tripled versus Opus 4.6.
  • Handles complex, long-running tasks with rigor: plans carefully, catches its own logical faults, and verifies its outputs before reporting back.

2. Long-horizon agent reliability

  • Full 1M token context window at standard pricing, with state-of-the-art long-context consistency.
  • Far fewer tool errors, stronger recovery from tool failures, and better follow-through on multi-step workflows - designed for async work like CI/CD, automations, and managing multiple agents in parallel.
  • Stronger file-system-based memory, retaining useful notes across long, multi-session runs.

3. Sharper instruction following and honesty

  • Takes instructions literally and precisely - existing prompts may need re-tuning since earlier models were more lenient.
  • More honest about its own limits: reports missing data instead of fabricating plausible-but-wrong answers, and resists dissonant-data traps that tripped up Opus 4.6.

4. Substantially improved vision and multimodal reasoning

  • Accepts images up to 2,576 px on the long edge (~3.75 MP) - over 3x more than prior Claude models.
  • Unlocks dense-screenshot computer use, complex diagram extraction, and pixel-perfect reference tasks.
  • Stronger document reasoning for enterprise analysis (e.g., 21% fewer errors than Opus 4.6 on Databricks' OfficeQA Pro).

5. Top-tier professional knowledge work

  • State-of-the-art on the Finance Agent evaluation and GDPval-AA, with tighter, more professional finance analyses, models, and presentations.
  • Strong on legal work - e.g., 90.9% on BigLaw Bench at high effort, with better-calibrated reasoning on review tables and ambiguous edits.
  • Noted by design-focused partners as the best model for building dashboards and data-rich interfaces.

6. Modern effort and budget controls

  • Introduces a new xhigh effort level between high and max for finer control over reasoning vs. latency.
  • Task budgets (public beta) let developers guide token spend across long runs.
  • Recommended to start with high or xhigh effort for coding and agentic use cases.

Grok 3 Mini

1. Lightweight but thoughtful reasoning

  • Designed to 'think before responding' with accessible raw thought traces.
  • Excellent for logic puzzles, lightweight reasoning, and systematic tasks.

2. Extremely cost-efficient

  • Only $0.30 per 1M input tokens and $0.50 per 1M output tokens.
  • Cached token support lowers cost to $0.075 per 1M tokens.

3. Fast and responsive

  • Optimized for low-latency applications and high-throughput use cases.
  • Suitable for chatbots, assistants, and automation flows.

4. Supports modern developer features

  • Function calling for tool-augmented workflows.
  • Structured outputs for schema-controlled responses.
  • Integrates cleanly with agents and pipelines.

5. Large 131K context window

  • Can understand and work with long documents, transcripts, or multi-turn sessions.

6. Great for non-domain-heavy tasks

  • Useful for summarization, rewriting, extraction, everyday reasoning, and app logic.
  • Does not require domain expertise to operate effectively.

7. Compatible with enterprise infrastructure

  • Stable rate limits: 480 requests per minute.
  • Same API structure as all Grok 3 models.

8. Optional Live Search support

  • $25 per 1K sources for real-time search augmentation.

FAQs

Is Claude 4.7 Opus cheaper than Grok 3 Mini?

Grok 3 Mini is generally cheaper: $0.3 input / $0.5 output per million tokens, versus $5 / $25 for Claude 4.7 Opus. Actual cost depends on how many tokens your workload reads and writes.

Which has the larger context window, Claude 4.7 Opus or Grok 3 Mini?

Claude 4.7 Opus has the larger context window at 1M tokens, compared to 131.1K tokens for Grok 3 Mini. A larger window means the model can consider more text at once - useful for long contracts, codebases, or months of records.
