OpenAI has introduced a considerable value reduce on o3, its flagship reasoning giant language mannequin (LMM), slashing prices by a whopping 80% for each enter and output tokens.
(Recall tokens are the person numeric strings that LLMs use to signify phrases, phrases, mathematical and coding strings, and different content material. They’re representations of the semantic constructions the mannequin has realized by means of coaching, and in essence, are the LLMs’ native language. Most LLM suppliers provide their fashions by means of utility programming interfaces or APIs that builders can construct apps atop of or plug their exterior apps into, and most LLM suppliers cost them for the privilege at a value per million tokens).
The replace positions the mannequin as a extra accessible possibility for builders in search of superior reasoning capabilities, and locations OpenAI in additional direct pricing competitors with rival fashions resembling Gemini 2.5 Professional from Google DeepMind, Claude Opus 4 from Anthropic, and DeepSeek’s reasoning suite.
Introduced by Altman himself on X
Sam Altman, CEO of OpenAI, confirmed the change in a publish on X highlighting that the brand new pricing is meant to encourage broader experimentation, writing: “we dropped the price of o3 by 80%!! excited to see what people will do with it now. think you’ll also be happy with o3-pro pricing for the performance :)”
The price of utilizing o3 is now $2 per million enter tokens and $8 per million output tokens, with an additional low cost of $0.50 per million tokens when the person enters info that has been “cached,” or is saved and similar to what they supplied earlier than.
This marks a major discount from the earlier charges of $10 (enter) and $40 (output), as OpenAI researcher Noam Brown identified on X.
Ray Fernando, a developer and early adopter, celebrated the pricing drop in a publish writing “LFG!” brief for “let’s fucking go!”
The sentiment displays a rising enthusiasm amongst builders trying to scale their tasks with out prohibitive mannequin entry prices.
Worth comparability to different rival reasoning LLMs
The value adjustment comes at a time when AI suppliers are competing extra aggressively on each efficiency and affordability. A comparability with different main AI reasoning fashions illustrates how important this transfer may very well be:
Gemini 2.5 Professional Preview, developed by Google DeepMind, costs between $1.25 and $2.50 for enter relying on immediate dimension, and $10 to $15 for output. Whereas its integration with Google Search affords extra performance, that service carries its personal value — free for the primary 1,500 requests per day, then $35 per thousand requests.
Claude Opus 4, marketed by Anthropic as a mannequin optimized for advanced duties, is the most costly of the group, charging $15 per million enter tokens and $75 for output. Immediate caching learn and write companies come at $1.50 and $18.75 respectively, though customers can unlock a 50% low cost with batch processing.
DeepSeek’s fashions, significantly DeepSeek-Reasoner and DeepSeek-Chat, undercut a lot of the market with aggressive low pricing. Enter tokens vary from $0.07 to $0.55 relying on caching and time of day, whereas output ranges from $1.10 to $2.19. Discounted charges throughout off-peak hours deliver costs down even additional, to as little as $0.035 for cached inputs.

As well as, unbiased third-party AI mannequin comparability and analysis group Synthetic Evaluation ran the brand new o3 by means of its suite of benchmarking assessments on numerous duties, and located it value $390 to finish all of them, versus $971 for Gemini 2.5 Professional and $342 for Claude 4 Sonnet.
Narrowing the price vs. intelligence hole for builders
OpenAI’s pricing transfer not solely narrows the hole with ultra-low-cost fashions like DeepSeek but additionally places downward stress on higher-priced choices like Claude Opus and Gemini Professional.
Not like Claude or Gemini, OpenAI’s o3 additionally now affords a flex mode for synchronous processing that costs $5 for enter and $20 for output per million tokens, giving builders extra management over compute value and latency relying on workload kind.
o3 is presently out there by means of the OpenAI API and Playground. Customers with balances as little as a couple of {dollars} can now discover the mannequin’s full capabilities, enabling prototyping and deployment with fewer monetary limitations.
This might significantly profit startups, analysis groups, and particular person builders who beforehand discovered higher-tier mannequin entry cost-prohibitive.
By considerably decreasing the price of its most superior reasoning mannequin, OpenAI is signaling a broader development within the generative AI area: premium efficiency is rapidly changing into extra reasonably priced, and builders now have a rising variety of viable, economically scalable choices.
