What are the official 2026 LLM API prices per 1M tokens for GPT-6.1 Sol, Claude Opus 5.5, Sonnet 5.5, Gemini 4 Argon, and DeepSeek V4 Pro?

Verified v17-unified rates (per 1M tokens, input / cached input / output): OpenAI GPT-6.1 Sol is $2.00 / $0.10 / $10.00 (>272K cliff: $4.00 / $0.20 / $15.00); Claude Opus 5.5 is $4.00 / $0.20 / $20.00 (1M flat window); Claude Sonnet 5.5 is $2.00 / $0.10 / $10.00 (1M flat window); Claude Haiku 5.5 is $0.10 / $0.01 / $0.50 (>100K 5x cliff: $0.50 / $0.05 / $2.50); Gemini 4 Argon is $2.00 / $0.10 / $10.00 through Nov 30, 2026 ($4.00 / $0.20 / $20.00 from Dec 1, 2026); DeepSeek V4 Pro is $0.66 / $0.022 / $1.98 Off-Peak ($1.32 / $0.044 / $3.96 Peak); DeepSeek V4.1-Flash-1017 is $0.15 / $0.003 / $0.60 Off-Peak.

How does Etuki calculate Effective Cost per Successful Task (C_success) and verify real customer bills via Bill X-Ray & Cost Regression CI?

Etuki computes C_success = E[C_total] / P(success) via /api/v1/effective-cost, calibrating for tokenizer density (Claude 4.7+/5.5 ~1.28x vs OpenAI o200k 1.00x), piecewise context cliffs, prefix cache hits, and transport retries. Teams can verify real CSV bills in the browser-local Bill X-Ray (#live-bill-verifier), replay REG-01..REG-05 in /api/v1/gateway-sandbox across 4 rollout stages (Dry-Run, Shadow, Canary 10%, Production + Auto-Rollback), and block >15% PR cost regressions via /api/v1/ci-gate.

How does the Etuki Universal FinOps Execution Compiler prevent 272K, 200K, 100K, and 256K context-cliff bill spikes?

Etuki enforces a two-tier soft-block routing architecture: Tier 1 intercepts prompts at 90% of hard vendor cliffs (244,800 tokens for OpenAI >272K, 180,000 for Grok/Gemini >=200K, 90,000 for Haiku >100K) and reroutes overflow to flat-window Claude Sonnet 5.5. Tier 2 takes precedence for Alibaba Qwen 3.7 Flash, keeping 32K-230.4K prompts on Qwen 3.7 Flash (0.96 CNY/1M) and rerouting >230,400 tokens (90% of 256K cliff) to Qwen 3.8 Flash (0-1M flat tier at 1.18 CNY/1M).
