OpenAI cuts GPT-5.6 Sol pricing by 20%+ in second reduction this month

OpenAI announced the cut directly via its official account — "we're dropping API and credit pricing of GPT-5.6 Sol by over 20% for the next 3 months" — a post that drew more than 13,000 likes and a retweet from Sam Altman. On Amazon Bedrock the reductions land at $4 per million input tokens and $20 per million output tokens, described as 20% lower input and 33.3% lower output pricing, following recent Terra and Luna reductions across the family.

The mechanics are straightforward: a promotional rate applied through November 21, 2026 spanning the pay-as-you-go API, Codex credits, and eligible ChatGPT Work plans. The timing is anything but incidental. It is OpenAI's second Sol-family price drop in under a month, a cadence that signals margin compression is now a deliberate competitive lever rather than an occasional gesture.

Competitively, the cut is a direct response to aggressive pricing from Google's Gemini 3.7 Flash ($0.75/$3.75 per 1M) and xAI's Grok 4.6 (~$8 combined per 1M), both of which developers have praised as undercutting frontier incumbents on production code. OpenAI is defending the top of the market while rivals commoditize the mid-tier, and Bedrock availability with cross-region inference broadens the model's reach across 25+ AWS regions.

What to watch: whether the November expiry becomes a recurring 'introductory' pattern that developers learn to distrust, and whether the price floor forces Anthropic — whose Opus/Sonnet tier still commands $30–60 per 1M combined — to respond. Community sentiment already frames the frontier as caught in a 'release velocity fatigue' cycle with roughly 11 days between frontier releases, and pricing is the clearest front in that war.
