Verified 2026 FinOps benchmark comparing OpenAI GPT-6.1 Sol (gpt-6.1-sol) vs Perplexity: Sonar Pro Search (perplexity/sonar-pro-search). Simulate cache read multipliers, context cliffs, MAU bills, and P90 latency.
OpenAI & Microsoft Founders Hub ($2,500–$150,000 Credits) + 50% Batch API Discount
OpenAI GPT-6.1 Sol ($2/$10 base rate) qualifies for immediate 75% automatic prefix caching ($0.50/1M), 50% off 24-hour Batch API completions ($1/$5), and up to $150,000 in OpenAI/Azure Foundry credits via Microsoft for Startups Founders Hub (no VC funding required for initial tiers).
Perplexity: Sonar Pro Search (perplexity/sonar-pro-search) 2026 Q4 Developer Promotion & Volume Credits
Official 2026 Q4 promotion for Perplexity: Sonar Pro Search: Activate ephemeral prefix caching to slash input costs by 50% (down to $1.5/1M) or route via asynchronous Batch API for 50% off standard token rates.
In Etuki October 2026 FinOps telemetry comparing OpenAI GPT-6.1 Sol (API ID: gpt-6.1-sol) vs Perplexity: Sonar Pro Search (API ID: perplexity/sonar-pro-search), OpenAI GPT-6.1 Sol offers lower standard input pricing at $2/1M tokens ($10/1M output), while OpenAI GPT-6.1 Sol leads in cached prefix economics at $0.5/1M tokens (75% discount). OpenAI GPT-6.1 Sol achieves a 10ms faster P90 time-to-first-token latency (270ms vs 280ms).
Context Cliff Alert: Prompts exceeding 272K tokens double in price from $2/$10 to $4/$15 per 1M tokens.
