How Claude 4.5 Opus and QVQ-Max differ
What the numbers mean in practice when choosing between Claude 4.5 Opus and QVQ-Max.
-
QVQ-Max is 77% cheaper on input tokens ($1.147 vs $5 per million), which adds up quickly in document-heavy workloads.
-
QVQ-Max is 82% cheaper on output tokens ($4.588 vs $25 per million) - the bigger factor for tools that generate long documents.
-
Claude 4.5 Opus's 200K tokens context window is roughly 1.5x larger than QVQ-Max's 131.1K tokens, so it can work across bigger codebases, contracts, or archives in one pass.
-
These are different kinds of model: Claude 4.5 Opus is a text model while QVQ-Max is a vision model, so they often complement each other in a workflow rather than compete.
-
Claude 4.5 Opus has been superseded by Claude 4.6 Opus - for new builds, consider the newer model first.
Strengths side by side
Where each model shines, according to benchmarks and provider positioning.
Claude 4.5 Opus
1. Maximum capability with more practical pricing
- Anthropic introduced Opus 4.5 as its most intelligent model, combining maximum capability with practical performance.
- It was positioned as the best model in the world for coding, agents, and computer use at launch, with pricing reduced to $5/M input and $25/M output.
2. Step-change gains for coding and advanced agent work
- Anthropic describes Opus 4.5 as state-of-the-art on real-world software engineering tests.
- It also improved everyday knowledge-work tasks like deep research, slides, and spreadsheets while staying strong on long-horizon agent workflows.
3. Better control over reasoning depth
- Opus 4.5 introduced the
effortparameter, letting developers trade off response thoroughness against token efficiency. - This made it easier to use one flagship model across both high-depth analysis and more cost-sensitive production workloads.
4. Stronger computer use and continuity
- Added enhanced computer use with a zoom action for inspecting detailed screen regions.
- Preserves prior thinking blocks across turns, helping the model maintain reasoning continuity in extended multi-step tasks.
QVQ-Max
1. Strongest visual reasoning in Qwen lineup
- Handles charts, diagrams, puzzles.
2. Great for math + vision hybrids
- Geometry, visual logic testing.
3. High-quality instruction following
- Consistent formatting and detailed responses.

FAQs
QVQ-Max is generally cheaper: $1.147 input / $4.588 output per million tokens, versus $5 / $25 for Claude 4.5 Opus. Actual cost depends on how many tokens your workload reads and writes.
Claude 4.5 Opus has the larger context window at 200K tokens, compared to 131.1K tokens for QVQ-Max. A larger window means the model can consider more text at once - useful for long contracts, codebases, or months of records.
