Provider: openai  
Category: llm  
Model ID: `openai/gpt-6-sol-pro:batch`

GPT-6 Sol Pro is the same underlying model as [GPT-6 Sol](https://openrouter.ai/openai/gpt-6-sol), served with `reasoning.mode` set to `pro` for higher-quality responses on complex tasks. **Cost note:** pro mode spends far more...

## Specs

- Context length: 1050000 tokens
- Max output: 128000 tokens
- Modalities: file, image, text
- Released: 2026-09-22

## Pricing

- Input: $1.00 per million tokens
- Output: $5.00 per million tokens

## Providers

- **openai** — ctx 1050000, input $1.00/M, output $5.00/M

## Verdict

GPT-6 Sol Pro (batch) delivers OpenAI's latest reasoning architecture at batch pricing that undercuts real-time alternatives by 50%. The 1M+ token context window handles book-length documents and multi-file codebases without chunking. Batch mode introduces 24-hour latency, making this strictly for workloads where throughput matters more than speed. Reach for this when you're processing large volumes of complex tasks overnight — research synthesis, bulk code reviews, dataset annotation — and need frontier reasoning without real-time costs.
