Recommendation for Fast & cheap
Fast Summaries
Our top recommendation for Fast Summaries, based on the public evidence we track, is Google: Gemini 3.6 Flash.[1][2] Use for high-volume summarization pipelines where you need a model that scores 75.37% on instruction following benchmarks covering paraphrasing and simplification. OpenAI: GPT-5.6 Sol is the next-ranked alternative. Deploy when you need proven throughput for agentic chat workflows, as practitioners report staying on 5.4 variants for comparable results at higher speed.

Relative score combines normalized benchmark quality and signal coverage; independent practitioner evidence and freshness are bounded tie-breakers. It is an ordering score, not an absolute quality percentage. The writing model receives this order and cannot change it.
Gemini 3.6 Flash places in the top 12% on LMArena and top 14% on LiveBench Instruction Following, which includes summarization tasks.
Best when: Use for high-volume summarization pipelines where you need a model that scores 75.37% on instruction following benchmarks covering paraphrasing and simplification.

“I would be really interested in real life throughput. For an agentic chat situation, we are still on 5.4 - not because of the cost, but it's simply much faster than 5.5 with comparable results. Also we are using gpt-5.4-mini a lot for quick summaries, tldrs etc. In an ideal world we would upgrade 5.4 to 5.6 terra and 5.4 mini to 5.4 luna. But does somebody already have some measurements at least in terms of speed?”
