Gemini 3.6 Flash vs GPT-6 Sol

Decision reading

GPT-6 Sol has the higher public score estimate, 80.45 versus 68.73, but the 90% score intervals overlap. Treat that as a lead, not a settled winner.

1 results are shared. Category rows resting on Estimated evidence or different benchmark sets are marked directional and do not name a winner.

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.

The same task catalog as the LLM Selector. Each job names the evidence surface it rests on; nothing here adds a new score.

What is actually comparable

Shared results can support a head-to-head reading. Results present for only one model describe coverage, not superiority.

Category results, on a stated basis

Each row shows the public-lane category score for both models: the BenchAlign 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) differ from the provisional-lane categories. Unranked scores sit on the lane’s scale but never name a winner. Like-for-like rows within 0.5 points read as a practical tie.

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.

Questions

Which is better, Gemini 3.6 Flash or GPT-6 Sol?

GPT-6 Sol has the higher public score estimate, 80.45 versus 68.73, but the 90% score intervals overlap. The higher estimate is not a decisive winner because the uncertainty ranges overlap.

Which is better for coding, Gemini 3.6 Flash or GPT-6 Sol?

GPT-6 Sol scores higher for coding on the public lane, 74.3 to 58.2. GPT-6 Sol is 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, Gemini 3.6 Flash or GPT-6 Sol?

GPT-6 Sol scores higher for agentic tasks on the public lane, 69.7 to 52.9. Gemini 3.6 Flash and GPT-6 Sol are scored on Estimated evidence for agentic tasks, so the reading is directional rather than like-for-like. BenchLM does not name a winner for agentic tasks from a directional reading; read the shared benchmark rows directly and test the models on the same task set.

Which costs less, Gemini 3.6 Flash or GPT-6 Sol?

For the stated presets, chat costs $0.00525 on Gemini 3.6 Flash and $0.007 on GPT-6 Sol; repository review costs $0.0975 and $0.13; the cache-heavy agent loop costs $0.135 and $0.18. Costs use the listed standard API rates.

Which has the larger context window, Gemini 3.6 Flash or GPT-6 Sol?

GPT-6 Sol has the larger documented context window: 1.05M, compared with 1M.
