Decision reading
The public evidence has no benchmark result shared by both models, so it does not support a quality verdict. Use the documented cost, context, and runtime rows instead. 0 results are shared. Category rows resting on Estimated evidence or different benchmark sets are marked directional and do not name a winner.

Not enough matched evidence
Claude 3 Opus and GPT-4.1 mini are scored on Estimated evidence for coding, so the reading is directional rather than like-for-like.
Confidence: limitedAgentic work
Tool use, computer use, and multi-step task completion
Not enough matched evidence
Claude 3 Opus and GPT-4.1 mini are not ranked on the public lane for agentic, so no winner is named for agentic.
Confidence: limitedCache-heavy agent loop cost

Not enough matched evidence
The page does not recommend a cost winner because at least one model cannot fit the stated workload in one request. Claude 3 Opus does not fit this workload in one request. Claude 3 Opus has no published cached-input rate, so cached tokens use its listed input rate. GPT-4.1 mini has no published cached-input rate, so cached tokens use its listed input rate.

Which one for a specific job
Choose a job from the LLM Selector's task catalog to see the category row it rests on, under the same basis rules as the table below. A directional row stays directional; choosing a job never creates a winner.

Directional only · BenchAlign v5.6
GPT-4.1 mini scores higher, but at least one score rests on Estimated evidence or a different benchmark set. Directional only, no winner.
Coding scores combine specific tasks and setups. Match the editor, harness, and effort to your workflow.

What is actually comparable
Shared results can support a head-to-head reading. Results present for only one model describe coverage, not superiority.
5 GPT-4.1 mini only
2 categories rest on Estimated evidence or different evidence sets. Those rows remain visible for coverage context but do not name a winner.
Shape of the matched evidence
Only shared public evidence is shown. Sparse evidence stays a ruled list rather than being closed into a radar shape.
A shared-evidence shape is not available.
BenchLM does not draw a radar or infer missing axes when the matched evidence is too sparse.
Category results, on a stated basis
Each row shows the public-lane category score for both models: the BenchAlign v5.6 lane for agentic, coding, and knowledge, and the weighted public rows elsewhere, with the same rank each model page reports. A row is like-for-like only when both scores rest on Supported evidence or the same weighted set. Directional and not-comparable rows remain visible, but they never receive a winner.

Ranks count the models scored in each category’s lane, so the agentic, coding, and knowledge denominators (BenchAlign v5.6) differ from the provisional-lane categories. Unranked scores sit on the provisional lane’s scale but never name a winner. Like-for-like rows within 0.5 points read as a practical tie.

If you already use one of these models
- Deployment change
- The models list different providers, so authentication, endpoint behavior, limits, and feature support may change.
- Quality signal
- The public evidence has no benchmark result shared by both models, so it does not support a quality verdict.
- Workload cost
- Repository review: $0.975 vs $0.0248. Cache-heavy agent loop: $4.05 vs $0.104.
- Context tradeoff
- GPT-4.1 mini has the larger documented window (1M).
Run the same representative tasks against both endpoints before changing production traffic.
Questions
Which is better, Claude 3 Opus or GPT-4.1 mini?
The public evidence has no benchmark result shared by both models, so it does not support a quality verdict. The page therefore keeps the decision tied to the specific documented workload.
Which is better for coding, Claude 3 Opus or GPT-4.1 mini?
GPT-4.1 mini scores higher for coding on the public lane, 24.9 to 20.9. Claude 3 Opus and GPT-4.1 mini are scored on Estimated evidence for coding, so the reading is directional rather than like-for-like. BenchLM does not name a winner for coding from a directional reading; read the shared benchmark rows directly and test the models on the same task set.
Which is better for agentic tasks, Claude 3 Opus or GPT-4.1 mini?
Claude 3 Opus and GPT-4.1 mini are not ranked on the public lane for agentic tasks, so no winner is named for agentic tasks.
Which costs less, Claude 3 Opus or GPT-4.1 mini?
For the stated presets, chat costs $0.0525 on Claude 3 Opus and $0.0012 on GPT-4.1 mini; repository review costs $0.975 and $0.0248; the cache-heavy agent loop costs $4.05 and $0.104. Claude 3 Opus does not fit this workload in one request. Claude 3 Opus has no published cached-input rate, so cached tokens use its listed input rate. GPT-4.1 mini has no published cached-input rate, so cached tokens use its listed input rate.
Which has the larger context window, Claude 3 Opus or GPT-4.1 mini?
GPT-4.1 mini has the larger documented context window: 1M, compared with 200K.
