OpenAI is an American artificial intelligence research organization headquartered in San Francisco, structured as both a for-profit public benefit corporation and a nonprofit foundation. The lab developed the GPT family of large language models, the DALL-E image generation…
Explore 22 more models by OpenAI →GPT-5.4, released in March 2026, is OpenAI's frontier model aimed at complex professional work, folding together advances in reasoning, coding, and agentic workflows into a single system. A defining change is its very large context window of roughly 1.05M tokens, which OpenAI says makes it easier to analyze entire codebases, long document collections, or extended agent trajectories in one request. It accepts text and image inputs and exposes a reasoning-effort control ranging from none through xhigh.
Compared with the earlier [[sibling:openai-gpt-52|GPT-5.2]], OpenAI reports improvements in coding, document understanding, tool use, and instruction following. The model also incorporates the coding capabilities of [[sibling:openai-gpt-53-codex|GPT-5.3 Codex]] into the mainline line, and is described as OpenAI's first general-purpose model with native, built-in computer-use capabilities, enabling agents to operate software in a build-run-verify-fix loop. Two further additions—native compaction for longer agent runs and tool search via deferred tool loading—target larger tool ecosystems and reduced token usage.
GPT-5.4 ships alongside lighter and heavier variants, including [[sibling:openai-gpt-54-mini|GPT-5.4 Mini]] and [[sibling:openai-gpt-54-pro|GPT-5.4 Pro]], the latter also offering the 1M+ context window. It was later succeeded within the same family by [[sibling:openai-gpt-55|GPT-5.5]]. For teams building agents, automating document-heavy workflows, or handling multi-step tool use, GPT-5.4 represents OpenAI's consolidated frontier endpoint.

"Best price" and the seller table are live AntSeed catalog data (advertised $/1M tokens — or $ per generated image for unit-billed image models — not settled amounts). Reputation = on-chain trust (0-100). "Routing" = the SDK's default buyer routing (what the VPR desktop app ships with): a trust ≥ 60 gate on the effective reputation, then cheapest-first among routable sellers; live failover state (per-peer cooldowns) is buyer-side runtime and not included. Model knowledge (TLDR, provider, About) via the VeniceStats enrichment layer. Advertised catalog, not the model used in any specific purchase. "Usage on AntSeed" counts only settlements whose buyers share the per-model split on-chain (metadata v2/v3, opt-in), so every usage figure is a lower bound.
