After Pausing Advanced AI Tests, OpenAI Slashes GPT-5.6 Sol Prices By 20%

OpenAI has reduced the price of its frontier GPT-5.6 Sol model for developers by more than 20% for the next three months, with new rates of $4 per million input tokens and $20 per million output tokens. The move applies to API and eligible credits for ChatGPT Work and Codex, while subscription prices remain unchanged. The cut is seen as a response to intensifying competition from Anthropic and Chinese AI developers.

OpenAI Slashes GPT-5.6 Sol API Prices for Developers

OpenAI announced on Friday that it is cutting the price of its frontier GPT-5.6 Sol model for developers by more than 20% for the next three months, a move attributed to growing competition from rivals such as Anthropic and Chinese AI companies.

The reduced pricing applies to OpenAI's API and is rolling out across eligible plans for credits on its agentic AI product ChatGPT Work and its coding tool Codex, the company said. Pro, Plus, and Business subscription prices remain unchanged.

New Pricing Details

According to OpenAI's pricing table, GPT-5.6 Sol now costs $4 per 1 million input tokens and $20 per 1 million output tokens for standard short-context use. The previous prices were $5 and $30 per million tokens respectively, representing a 20% reduction in input costs and nearly a 33% reduction in output costs. The lower prices will be available for three months.

This latest cut follows similar reductions last month for OpenAI's smaller models. The mid-tier GPT-5.6 Terra model was reduced by 20%, and the lower-cost Luna model by 80%, as reported by Deccan Chronicle.

Competitive Landscape

The price cut comes as OpenAI faces stronger competition from rival AI companies. Anthropic has been promoting its Claude models as alternatives to OpenAI's frontier systems, and Chinese AI companies have also been developing increasingly capable models.

Comparing the pricing, Anthropic lists its Claude Fable 5 model at $10 per 1 million input tokens and $50 per 1 million output tokens, while its Claude Opus 5 model is listed at $5 per 1 million input tokens and $25 per 1 million output tokens. According to Times Now, with the temporary reduction, GPT-5.6 Sol is now cheaper than both Anthropic models on both input and output pricing.

Context and Reporting Nuances

While both Deccan Chronicle and Times Now reported the price cut and the new rates, only Times Now mentioned that OpenAI had temporarily paused testing its advanced AI models before making the announcement. This detail was not present in Deccan Chronicle's coverage.

Times Now also framed the price cut as a response to rising competition from Chinese AI models and American rivals, while Deccan Chronicle similarly attributed the cut to growing competition from Anthropic and Chinese AI models. Neither outlet suggested any other motive for the pricing change.

Outlook

The three-month price reduction is aimed at developers and users of OpenAI's API and eligible AI tools, potentially easing the cost of building on GPT-5.6 Sol during a period of intensifying competition in the AI model market. Whether this temporary cut will become permanent remains to be seen, but for now, developers can take advantage of the reduced rates on input and output tokens.

How each outlet told it

Framing: Headline emphasizes the pause in AI tests and the price cut, framing the cut as a subsequent action; includes a sub-headline noting the price cut and what changes. — Informative and slightly promotional, as seen in phrases like 'major price cut' and the explicit comparison showing GPT-5.6 Sol is cheaper than competitors.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
