OpenAI climbs to about half of shared customers' AI spending after cutting its smallest model's price 80%
OpenAI roughly matched Anthropic in September on spending by about 120,000 shared customers, up from a quarter at the start of the year, OpenRouter data shows. Both labs are now cutting small-model prices before planned IPOs, so share costs each of them revenue per request.

buildConfirmed2 publishers OpenAI says GPT-6 Sol, for demanding professional work, and GPT-6 Luna, for high-volume jobs, cost up to 50% less than comparable GPT-5.6 options. The split is by workload, so each job has to be tested on its own before a team counts on the full discount.

buildOne report1 publisher Adversa AI hides instructions from Copilot CLI's guardrails inside ciphertext the agent decrypts itself
Adversa AI got GitHub Copilot CLI to decrypt and run a hidden instruction, and Microsoft's mai-code-1.1-flash fell for it 50 percent of the time. GitHub declined to treat it as a product vulnerability, so teams running autopilot have to check what the agent executes themselves.

GitHub adds GPT-6.1 Sol to Copilot on an unquantified claim of fewer tokens and steps
GitHub is rolling GPT-6.1 Sol into Copilot, citing early tests in which it used fewer tokens and steps than GPT-6 and GPT-5.6, without figures. Teams will have to measure any saving on their own tasks, at a rate the announcement did not quote.

One OpenAI Codex prompt spawned 826 child agents and burned about $78,000 in credits, according to the user's own reconstruction. Nearly all the counted tokens trace to an alpha client build, and only OpenAI's servers can turn them into dollars.

Microsoft's new Copilot app bills coding and agents by use, while fewer than 7% of over 450 million commercial 365 seats pay for Copilot. Usage billing lets Microsoft charge its existing Copilot customers more whether or not the unlicensed majority ever signs up.

buildOne report1 publisher Default LLM calls pay list price for work that caching and batch would discount
A dev.to guide to GPT-5.6 pricing shows batch halving both token rates and a cheap-first cascade saving money until 9 in 10 calls escalate. Batch is opt-in and caching fails silently on short prefixes, so the default request often pays list price.
