(Luna −80%, Terra −20%) — Confirm the lower rate appears on your next invoice, then check whether tasks still pinned to Sol can safely move down to the now much cheaper Luna or Terra.Thu, 30 Jul 2026 00:00:00 GMTOpenAICuthttps://costmon.com/price-changes#github-copilot-ai-credits-2026https://costmon.com/price-changes#github-copilot-ai-credits-2026Every Copilot plan now gets a monthly allotment of GitHub AI Credits consumed by actual token usage, instead of a flat per-request charge that billed a quick question the same as a multi-hour agent session. ($10-$39 credits/mo) — Track per-seat credit burn from June 1, 2026, and budget for the promotional credit boost on Business/Enterprise expiring after August 2026.Mon, 27 Apr 2026 00:00:00 GMTGitHubRestructurehttps://costmon.com/price-changes#gpt-5-5-price-increasehttps://costmon.com/price-changes#gpt-5-5-price-increaseGPT-5.5 launched at roughly double GPT-5.4's per-token rate. OpenAI's own announcement frames this as a deliberate increase, offset by claimed gains in token efficiency per task. ($5 / $30 per M tokens) — Run a side-by-side cost comparison on real workloads before moving production traffic. Confirm the token savings offset the higher headline price for you.Fri, 24 Apr 2026 00:00:00 GMTOpenAIIncreasehttps://costmon.com/price-changes#vercel-turbo-build-machines-price-cut-2026https://costmon.com/price-changes#vercel-turbo-build-machines-price-cut-2026All build machine tiers now bill at a flat $0.0035 per CPU per minute, dropping the 30-CPU Turbo machine from $0.126 to $0.105 a minute.

Empty VPCs stay free. The announcement itself doesn't print a rate. AWS's VPC pricing page puts it at $0.15 per hour in US East (N. Virginia), rising to $0.31 in the priciest regions. ($0.15 / VPC-hour (us-east-1)) — Audit which VPCs need enforce mode versus monitor mode, and turn it off on non-empty VPCs where it isn't earning its per-hour charge. Check your own region's rate too; it's up to twice the US East price.Sun, 01 Mar 2026 00:00:00 GMTAWSNew chargehttps://costmon.com/price-changes#gemini-3-flash-caching-batch-pricing-2025https://costmon.com/price-changes#gemini-3-flash-caching-batch-pricing-2025Gemini 3 Flash launched at $0.50 per million input tokens and $3 per million output tokens, with context caching standard rather than opt-in, plus a 50% discount for asynchronous Batch API jobs.

(e.g. $0.064→$0.0705/build-min (us-east1)) — Check your build pool's region against the new per-region rate table, and shift latency-insensitive builds to a cheaper region if yours got more expensive.Wed, 15 Oct 2025 00:00:00 GMTGoogle CloudIncreasehttps://costmon.com/price-changes#claude-haiku-4-5-pricinghttps://costmon.com/price-changes#claude-haiku-4-5-pricingThe new small model launched at a flat $1 input / $5 output per million tokens, positioned by Anthropic as Sonnet-4-level coding at a third of the cost.
