GPT 5.4 Released, Fixes Major Bug That Was Cheaper Than Claude

Waking up to find that GPT has been updated again. This industry is so competitive, with daily advancements where you surpass me and I surpass you, and it’s hard to tell when it will end.

It reminds me of the famous slap contest, where everyone is gritting their teeth and holding on, just waiting to see who can’t last.

No wonder the head of a certain company’s large model department is leaving; it’s tough to live in a state of constant readiness.

Back to the point, GPT has released version 5.4, with thinking and pro launching simultaneously, now available on web, client, and API.

What Are the Major Updates?

- ① The coding capabilities of GPT-5.3-Codex have been merged in.

• ② Tool invocation and agent workflows are stronger, with some saying it’s the best partner for crawfish.
• ③ Enhanced web search and deep research capabilities, especially for multi-round searches, multi-source integration, and finding needles in haystacks.
• ④ Significant improvements in Office tasks like PPT, documents, and spreadsheets.
• ⑤ Greatly enhanced computer operation capabilities, with assessments stating it’s stronger than humans. (OSWord test: Human 72.36% | GPT-5.4: 75%)
• ⑥ Longer context and higher token usage efficiency, with a maximum of 1M context, allowing for entire code repositories to be pasted in. However, be aware that longer contexts are indeed very costly.
• ⑦ Supports making changes while working, allowing interruptions to modify prompts.

Overall, compared to several predecessors: 5.2 is a strong reasoning model, 5.3-Codex is a strong coding model, and this 5.4 is an all-around model after capability integration, aimed at real professional tasks.

An interesting point is that the 5.3-instant version was just released for a day when OpenAI hurriedly launched 5.4. What’s the reason?

Someone revealed the secret: 5.4 successfully fixed the major bug that made pricing cheaper than Claude.

Hahaha.

Looking closely at this latest pricing, it’s clear that OpenAI has significantly adjusted prices with this release, aligning the standard version closely with Sonnet 4.6, while the Pro version’s price has already outperformed Claude’s flagship model Opus 4.6.

However, the coding experts in the community have given very positive feedback on this update, stating "AI really becomes stronger with investment; GPT Pro handles coding much more smoothly than Claude, which tends to go off track too easily."

It seems that after securing $110 billion in funding, OpenAI feels more pressure to generate revenue.
