Strengths side by side
Where each model shines, according to benchmarks and provider positioning.
Claude 4 Sonnet
- Hybrid reasoning: supports both fast (“near-instant”) and extended thinking modes.
- Optimised for responsiveness, cost and high-volume production workloads.
- Strong coding performance relative to prior Sonnet versions (improved over Sonnet 3.7).
- Available even in free tiers (alongside paid plans).
- Better suited for general-purpose use and agents where speed + cost-efficiency matter.
Claude 4 Opus
- Highest capability in the family: described as “our most powerful model yet” by Anthropic.
- Exceptional at long-running tasks requiring thousands of steps and sustained focus (e.g., continuous codebase work for hours).
- Excellent performance on benchmarks: e.g., SWE-bench 72.5 % and Terminal-bench 43.2 %.
- Designed for complex agentic workflows, deep reasoning, tool use, and large context windows.
- Placed under a higher safety classification (ASL-3) due to its frontier capability and risk profile.

FAQs
Claude 4 Opus and GPT-5.4 are the top education LLMs in 2026. Claude 4 Opus produces the clearest, most pedagogically sound explanations - adapting complexity naturally to the stated learner level. GPT-5.4 is strong for structured curriculum content, lesson plans, and assessment generation. Both handle subject-matter accuracy well, though STEM topics benefit from additional verification.
Claude 4 Sonnet is generally cheaper: $3 input / $15 output per million tokens, versus $15 / $75 for Claude 4 Opus. Actual cost depends on how many tokens your education workload reads and writes.
Claude 4 Sonnet has the larger context window at 1M tokens, compared to 200K tokens for Claude 4 Opus. For education tasks, a larger window means the model can consider more context at once without losing track.
