A solid GPT-5 series refinement with strong reasoning, but its output pricing makes it hard to recommend over Claude Sonnet 4.6 unless you're OpenAI-first.

Long Context
Use this when
Professionals and developers who need reliable, high-quality text generation and reasoning at a cost that scales reasonably with usage.
Skip this if
Avoid if your workload is cost-sensitive, heavily multimodal, or requires context windows beyond 128K — competitors offer better value or longer context at similar price points.
Strong instruction-following with improved consistency over GPT-5.2
Competitive reasoning quality for complex multi-step tasks at its price tier
Well-calibrated outputs with low hallucination rate compared to similarly priced models
128K context window handles most real-world document and codebase workflows
Weaknesses
Output cost of $14/1M tokens is steep compared to Claude Sonnet 4.6 (~$15) and Gemini 3.1 Pro, offering less differentiation at this tier
No native image generation or vision-first capabilities, limiting multimodal workflows
128K context falls short of Gemini 3.1 Pro's longer context options for large-scale document analysis

GPT-4 is OpenAI's original flagship large language model, released in March 2023, offering strong reasoning and instruction-following across text tasks. It represents the foundational GPT-4 release before later variants like GPT-4 Turbo or GPT-4o improved speed, cost, and context length.
Verdict
A once-groundbreaking model now badly outclassed by cheaper, faster, and more capable successors — only use it if you have no choice.

Best for teams or workflows locked into the original gpt-4 api that require reliable, high-quality text reasoning without needing long context or multimodal input.
Context
8k tokens
At $30/$60 per million tokens, this is one of the most expensive text-only models available. The 8,191-token context window is a hard ceiling that makes it unsuitable for most document-processing tasks. OpenAI continues to offer it for API backward compatibility but actively recommends migrating to GPT-4o or GPT-4 Turbo. New projects should not default to this model.

GPT-4 v0314 is a frozen snapshot of the original GPT-4 release from March 2023, preserved for reproducibility and regression testing. It offers the same core reasoning capabilities as early GPT-4 but lacks all subsequent improvements, fine-tuning updates, and safety refinements.
Verdict
An expensive museum piece: only justified if you need this exact model snapshot for legacy reproducibility.

This is a frozen March 2023 snapshot of GPT-4, not a current model. OpenAI may deprecate legacy snapshots with limited notice. The 8,191-token context window is a hard constraint. Cost is identical to much more capable current models, making this a poor choice for new projects.

OpenAI: GPT-5.3 Chat — added to UseRightAI
OpenAI: GPT-5.3 Chat (OpenAI) is now indexed. It supersedes GPT-5.2. A solid GPT-5 series refinement with strong reasoning, but its output pricing makes it hard to recommend over Claude Sonnet 4.6 unless you're OpenAI-first.
OpenAI: GPT-5.3 Chat is best for professionals and developers who need reliable, high-quality text generation and reasoning at a cost that scales reasonably with usage.. It is a strong fit when that workflow matters more than the tradeoffs around balanced pricing and balanced speed.
When should I avoid OpenAI: GPT-5.3 Chat?
Avoid if your workload is cost-sensitive, heavily multimodal, or requires context windows beyond 128K — competitors offer better value or longer context at similar price points.
What is a cheaper alternative to OpenAI: GPT-5.3 Chat?
Meta: Llama 3.1 8B Instruct is the lower-cost option to compare first when you want a similar workflow fit with less token spend.
What is a faster alternative to OpenAI: GPT-5.3 Chat?
GPT-5.4 is the better pick when response time matters more than maximum depth or premium quality.
