F02
Codex — AI Coding AgentapiCodex is an AI coding agent that works in parallel to write features, fix bugs, run tests, and manage pull requests — including automated code review via GitHub tagging. Available on Plus and above, with dedicated usage tiers in Pro $100 and Pro $200. Business and Enterprise plans support Codex seats for team-wide coding automation.
F03
Deep ResearchsearchChatGPT runs deep, multi-step research tasks on complex topics, synthesizing information from across the web into structured, cited reports. Available on Plus (10 runs/month), Pro $100 (50 runs/month), and Pro $200 (250 runs/month). Deep Research can also pull from connected apps via Business plan connectors.
F04

DeepSeek
TOP FEATURES · 12
F01
DeepSeek-V4 ModelsaiDeepSeek's V4 model family includes two API tiers — V4-Flash for fast general-purpose inference and V4-Pro for maximum reasoning performance. Both run on a Mixture-of-Experts architecture with a 1M token context window and 384K max output. Models are accessible via the free web chat at chat.deepseek.com, iOS/Android apps, and the REST API. Context caching reduces repeated prefix costs by 90%.
F02
Thinking Mode (Chain-of-Thought Reasoning)aiBefore outputting a final answer, DeepSeek's thinking mode produces a chain-of-thought reasoning trace (reasoning_content) to improve accuracy on complex tasks. Thinking mode is the default on V4-Pro and available on V4-Flash. Outputs run up to 384K tokens for extended reasoning chains.
F03
Tool Calls (Function Calling)automationDeepSeek's API allows the model to call external functions and tools to enhance its capabilities. Supported in both thinking and non-thinking modes, with a strict mode (Beta) that enforces exact JSON schema compliance on tool outputs.
F04
JSON Output (Structured Output)dataDeepSeek provides a JSON Output mode that guarantees the model returns valid, parseable JSON strings. Users set the response_format parameter to json_object and include a JSON example in their prompt to guide structured output for downstream parsing.
F05
Context Caching (KV Cache on Disk)storageThe DeepSeek API automatically caches request prefixes on disk for all users at no extra configuration. Repeated prefix tokens in subsequent requests trigger a cache hit, reducing cost from $0.28 to $0.0028 per 1M input tokens — a 90% discount.
F06
FIM Completion — Fill in the Middle (Beta)editingUsers can supply a code or text prefix and optional suffix, and the model fills in the middle content. Commonly used for code completion and content completion tasks, integrating natively with VS Code via the Continue plugin. Non-thinking mode only (V4 restriction). In V3.2, FIM was available in both modes; V4 restricts it to non-thinking mode.

Analysts, researchers, and knowledge workersDeep Research runs multi-step web investigations on complex topics and produces structured, cited reports equivalent to hours of manual research work. Available on Plus (10 runs/month), Pro $100 (50 runs/month), and Pro $200 (250 runs/month). On Business and Enterprise plans, Deep Research can also pull from connected apps including Google Drive, GitHub, and SharePoint, allowing internal data to be combined with public sources in a single research run.
Software engineers and development teamsCodex is an AI coding agent that works in parallel to write features, fix bugs, run tests, and review pull requests autonomously via GitHub integration. Teams can run multiple Codex agents simultaneously on separate tasks, with worktrees and reviewable diffs available in the Codex desktop app on Windows. Available on Plus and above; Business and Enterprise plans include Codex seats and administrative controls. GPT-5.5 Thinking (rolling out April 2026) further extends Codex's agentic coding performance.
Content creators, designers, and marketing teamsChatGPT covers text, voice, image, and video generation within one product and one subscription.
