OpenAI

Maximum capability variant of GPT-5.5 for research-grade and highest-stakes tasks. No cached-input discount available. Data residency endpoints incur a 10% price uplift.

OpenAI's newest flagship general-purpose model (April 2026). Excels at complex reasoning, coding, and creative tasks. Features a 1M+ token context window. Cached input drops 90% (to $0.50/MTok). Data residency endpoints incur a 10% price uplift.

Pro variant of GPT-5.4 for maximum capability within the 5.4 family. No cached-input discount. Data residency endpoints incur a 10% price uplift.

Recommended Azure OpenAI production workhorse (Global Standard). Strong reasoning, vision, and agentic workflows with up to 1.1M context (<272K standard pricing tier).

Ultra-efficient GPT-5.4 family model on Azure OpenAI (Global Standard). Lowest-cost GPT-5.4 tier with vision, tools, and 1.1M context.

Compact GPT-5.4 variant on Azure OpenAI (Global Standard). Strong mini model for coding, agentic subtasks, and multimodal chat with long context.

Efficient GPT-5 family model on Azure OpenAI (Global Standard). Balanced reasoning, vision, and tool use at lower cost than GPT-5.

Flagship GPT-5 model on Azure OpenAI (Global Standard). General-purpose frontier reasoning with vision, tools, and 272K context.

Cheapest model in OpenAI's lineup. $0.10/MTok input is competitive with the cheapest models on the market. Ideal for routing, extraction, and lightweight classification. Remains competitive even after GPT-5.5 launch.

Cost-efficient multimodal chat model on Azure OpenAI Global Standard. Vision-capable general-purpose model with 128K context.

Compact o-series reasoning model on Azure OpenAI (Global Standard). Excels at math, coding, and visual reasoning with a 200K context window.

Maximum reasoning capability in OpenAI's lineup. For workloads where correctness is paramount over cost. No cached-input or batch discount available.

Primary advanced reasoning model. Replaced o1 ($15/MTok) with an 87% price cut and improved performance. Excels at coding, math, science, and visual perception. Internal reasoning tokens are billed at output rates, which can multiply actual costs by 3-10x depending on task complexity.

Lightweight reasoning model. Positioned between o4-mini and o3 for cost/capability trade-offs. Context window expanded to 200K tokens.

Most cost-effective option for 1M-token context workloads. Best choice for long-document processing when cost matters. Reliable production model.

Best value for long-context tasks at low cost. 1M context window at only $0.40/MTok input.

Legacy flagship multimodal model. Still available for legacy integrations and multimodal (text + image + audio) use cases. Supports the Realtime API for low-latency voice. GPT-5 ($1.25/MTok) is now generally more capable at a lower price.

Previous flagship image generation model, now superseded by GPT Image 1.5. Still available and capable. Slightly more expensive than 1.5 at High quality tier. Pricing also available per-token (text + image tokens billed separately) via the Responses API. Génération image via RodiumAI POST /v1/images/generations (OpenAI upstream).

Current flagship image generation model. Best quality in OpenAI lineup (LM Arena Elo 1264). Supports Low/Medium/High quality tiers and text-to-image + image editing. Includes C2PA metadata in generated images. Also accessible via alias chatgpt-image-latest. Génération image via RodiumAI POST /v1/images/generations (OpenAI upstream).

Budget-friendly image generation. 50-70% cheaper than GPT Image 1.5. Cheapest entry point for API image generation at /bin/sh.005/image (low quality). Recommended for high-volume projects, social media, and testing. Génération image via RodiumAI POST /v1/images/generations (OpenAI upstream).

Ultra-low-cost GPT-5 family model on Azure OpenAI (Global Standard). Best for high-volume lightweight tasks with vision and tools.

Premium GPT-5 Pro model on Azure OpenAI (Global Standard). Highest-capability tier for complex reasoning; billed per token without cached-input tier on Azure.

Agentic coding model on Azure OpenAI (Global Standard). Unifies GPT-5.2-Codex performance with GPT-5.2 reasoning for software engineering and Codex-style agents.
