Excellent news, AI builders!
OpenAI has introduced a substantial price cut 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 via coaching, and in essence, are the LLMs’ native language. Most LLM suppliers supply their fashions via 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 price per million tokens).
The replace positions the mannequin as a extra accessible possibility for builders searching for superior reasoning capabilities, and locations OpenAI in additional direct pricing competitors with rival fashions similar to 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 post on X highlighting that the brand new pricing is meant to encourage broader experimentation, writing: “we dropped the worth of o3 by 80%!! excited to see what individuals will do with it now. suppose you’ll even be proud of o3-pro pricing for the efficiency :)”
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 equivalent to what they offered 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 initiatives with out prohibitive mannequin entry prices.
Value comparability to different rival reasoning LLMs
The worth 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, prices between $1.25 and $2.50 for enter relying on immediate measurement, 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 complicated duties, is the most costly of the group, charging $15 per million enter tokens and $75 for output. Immediate caching learn and write providers come at $1.50 and $18.75 respectively, though customers can unlock a 50% low cost with batch processing.
- DeepSeek’s fashions, notably 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.
| Mannequin | Enter | Cached Enter | Output | Low cost Notes |
|---|---|---|---|---|
| OpenAI o3 | $2.00 (down from $10.00) | $0.50 | $8.00 (down from $40.00) | Flex Processing: $5 / $20 |
| Gemini 2.5 Professional | $1.25 – $2.50 | $0.31 – $0.625 | $10.00 – $15.00 | Increased fee applies to prompts >200k tokens |
| Claude Opus 4 | $15.00 | $1.50 (learn) / $18.75 (write) | $75.00 | 50% off with batch processing |
| DeepSeek-Chat | $0.07 (hit)$0.27 (miss) | — | $1.10 | 50% off throughout off-peak hours |
| DeepSeek-Reasoner | $0.14 (hit)$0.55 (miss) | — | $2.19 | 75% off throughout off-peak hours |
As well as, unbiased third-party AI mannequin comparability and analysis group Synthetic Evaluation ran the brand new o3 via 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 associated fee 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 strain on higher-priced choices like Claude Opus and Gemini Professional.
In contrast to Claude or Gemini, OpenAI’s o3 additionally now affords a flex mode for synchronous processing that prices $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 at present out there via the OpenAI API and Playground. Customers with balances as little as just a few {dollars} can now discover the mannequin’s full capabilities, enabling prototyping and deployment with fewer monetary limitations.
This might notably 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 pattern within the generative AI area: premium efficiency is shortly turning into extra inexpensive, and builders now have a rising variety of viable, economically scalable choices.
