O GPT-5.4

UkratkoStanje: 23. septembar 2026.

GPT-5.4 je model od OpenAI iz kategorije Multimodalni. Na Railwailu, GPT-5.4 košta 3,00 US$ po 1M ulaznih tokena i 18,00 US$ po 1M izlaznih tokena. Kontekstni prozor sadrži 1.050.000 tokena, a jedan odgovor može biti dugačak do 128.000 tokena.

GPT-5.4 is OpenAI's frontier model as of 2026, merging the previously separate GPT and o-series reasoning lines into a single unified architecture. Native multimodal input (text + images), 1.05M-token experimental context window (272K standard), 128K max output, integrated 'Thinking' tier for reasoning on demand. Best for: high-context coding, agentic engineering, multimodal analysis, complex tool-use workflows. The Codex line has been absorbed into this model.

O OpenAI

Osnovano 2015 · San Francisco, USA

OpenAI was founded in December 2015 by Sam Altman, Elon Musk, Greg Brockman, Ilya Sutskever, Wojciech Zaremba and John Schulman as a non-profit AI research organisation; it transitioned to a 'capped-profit' structure in 2019. OpenAI authored the GPT lineage starting with GPT-1 (2018), GPT-2 (2019), GPT-3 (2020), the ChatGPT launch with GPT-3.5 (November 2022), GPT-4 (March 2023), GPT-4o (May 2024), the o-series reasoning models o1 (December 2024) and o3 (early 2025), then GPT-5 (mid-2025). The GPT-5.x series unified the reasoning o-series with the general-purpose GPT line: GPT-5.2 shipped December 2025, GPT-5.3-Codex February 2026, GPT-5.4 in March 2026 and the GPT-5.5 family later in 2026. OpenAI's investors include Microsoft (~$13B+), Khosla Ventures, Andreessen Horowitz, Thrive Capital and Sequoia, with total funding exceeding $60 billion and a 2026 valuation above $300 billion.

Arhitektura

Unified Transformer with integrated reasoning ('Thinking') tier

GPT-5.4 is OpenAI's frontier model as of March 2026 and marks the full convergence of the previously separate o-series reasoning models and general-purpose GPT line into a single unified architecture. The o1, o3, o3-pro and o4-mini reasoning models were retired from ChatGPT on February 13, 2026; their capabilities are now folded into GPT-5.x as a 'Thinking' tier that activates on demand. GPT-5.4 also absorbs the Codex line for agentic coding. Pretraining used a multi-trillion-token mixture of web text, code repositories, scientific papers, books and licensed datasets on OpenAI's most recent supercomputer cluster. Post-training combined supervised fine-tuning, RLHF and large-scale reinforcement learning against verifiable rewards on coding, math and tool-use trajectories. The model supports native text + image input and a 1.05M-token experimental context window (272K standard), 128K max output, integrated tool-use, function calling, structured outputs, and built-in 'Tool Search' for delegating to subagents. Safety training followed OpenAI's Preparedness Framework with red-teaming, capability evaluations and external assessments.

Obuka i licenca

Pretrained on a multi-trillion-token mixture of web text, code, scientific papers, books and licensed datasets. Post-training combines supervised fine-tuning, RLHF and large-scale reinforcement learning against verifiable rewards on coding, math and tool-use tasks. Knowledge cutoff approximately late 2025.

Licenca: Proprietary commercial license via OpenAI API and Azure OpenAI. Commercial use permitted under OpenAI's Usage Policies.

Testiranje sigurnosti: Evaluated under OpenAI's Preparedness Framework with internal and external red-teaming, capability evaluations and a public Bug Bounty programme.

Poznata ograničenja

1M context is experimental and must be enabled explicitly (default is 272K)
Prompts above 272K input tokens are billed at 2x input / 1.5x output for the full session
No native audio or video input in this variant
Higher latency and cost than mini/nano tiers, especially with Thinking enabled
Knowledge cutoff in late 2025
