Long Context
Use this when
Tackling hard technical problems — from competition-level math to multi-step code debugging — where accuracy matters more than speed.
Skip this if
You need fast responses for conversational use, creative writing, or image-related tasks — or if your budget is tight and tasks don't require deep reasoning.
Top-tier performance on complex mathematical and logical reasoning tasks
Strong multi-step code generation and debugging with self-verification
200K context window allows analysis of large codebases or research documents
Significantly outperforms o1 on ARC-AGI and AIME benchmarks
Weaknesses
Deliberate reasoning means latency is high — unsuitable for real-time or chat applications
At $8/1M output tokens, costs can escalate quickly on long reasoning chains
Not designed for creative writing, image tasks, or casual conversation

OpenAI: GPT-4 Turbo
GPT-4 Turbo is OpenAI's high-capability flagship model featuring a 128K context window, trained on data up to April 2024. It delivers strong reasoning, coding, and instruction-following across complex tasks.
Verdict
A capable but aging flagship that has been outpaced by cheaper, faster successors in OpenAI's own lineup.

Context

GPT-4 Turbo is available via the OpenAI API. It has largely been succeeded by GPT-4o, which is faster, supports vision natively, and is cheaper. Organizations should evaluate whether migrating to GPT-4o or o3 makes more sense before building new workflows on this model.
GPT-4 Turbo (v1106) is an older snapshot of OpenAI's flagship GPT-4 Turbo model released in November 2023, offering a 128K context window with strong general-purpose reasoning and instruction-following capabilities. It predates later GPT-4 Turbo updates and GPT-4o, making it a legacy choice for workflows locked to this specific version.
Verdict
A reliable but outdated GPT-4 snapshot that only makes sense when version pinning is a hard requirement.

This is a pinned model snapshot (v1106) and will not receive capability updates. OpenAI may deprecate older snapshots over time. Knowledge cutoff is April 2023. Not recommended for new deployments given the superior cost-performance of GPT-4o and GPT-4.1.
