Decision reading

Step 3.7 Flash has the higher public score estimate, 51.05 versus 48.17, but the 90% score intervals overlap. Treat that as a lead, not a settled winner.

1 results are shared. Category rows based on different benchmark sets are marked directional and do not name a winner.

Which one for your work

Recommendations appear only when a shared evidence basis or an explicit operating constraint supports the call. Secondary and unsupported use cases stay disclosed below the initial list.

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.

What each workload costs

Three fixed token mixes turn per-token rates into comparable decisions. Each scenario states context fit and whether cached input had to fall back to the published list-input rate.

Frequently asked questions

Which is better, Step 3.7 Flash or Trinity-Large-Thinking?

Step 3.7 Flash has the higher public score estimate, 51.05 versus 48.17, but the 90% score intervals overlap. The higher estimate is not a decisive winner because the uncertainty ranges overlap.

Which is better for coding, Step 3.7 Flash or Trinity-Large-Thinking?

The published evidence does not provide a shared weighted coding basis for both models, so BenchLM does not name a coding winner.

Which is better for agentic tasks, Step 3.7 Flash or Trinity-Large-Thinking?

The published evidence does not provide a shared weighted agentic tasks basis for both models, so BenchLM does not name a agentic tasks winner.

Which costs less, Step 3.7 Flash or Trinity-Large-Thinking?

For the stated presets, chat costs $0.00077 on Step 3.7 Flash and $0.0007 on Trinity-Large-Thinking; repository review costs $0.01345 and $0.0152; the cache-heavy agent loop costs $0.0555 and $0.064. Step 3.7 Flash has no published cached-input rate, so cached tokens use its listed input rate. Trinity-Large-Thinking has no published cached-input rate, so cached tokens use its listed input rate.

Which has the larger context window, Step 3.7 Flash or Trinity-Large-Thinking?

Trinity-Large-Thinking has the larger documented context window: 512K, compared with 256K.
