OpenAI
Broadest model suite in the industry. GPT-5.2 is the flagship (400k context, vision, $1.75/$14 per 1M tokens). GPT-5.3-Codex is the top agentic coding model (state-of-the-art on SWE-Bench Pro). o3 for chain-of-thought reasoning ($10/1M input), o4-mini for cost-efficient reasoning ($1.10/$4.40). GPT-5.1-high scores ~1457 ELO on LMArena. DALL-E for image gen, Whisper for speech-to-text, Realtime API for voice. Batch API offers 50% discount. GPT-5.2 Pro with extended thinking at $21/$168 per 1M tokens.

Strengths & Weaknesses
Strengths:- dx
- reliability
- performance
- Most expensive top-tier models (GPT-5.2 Pro at $168/1M output)
- Closed-source, no self-hosting
- Rate limits can be restrictive for new accounts
- Structured output schema validation issues with Responses API
- SDK type instantiation errors with zodResponseFormat
- gpt-5.1-mini model availability/reliability issues
When to Use
Best when:- Need broadest model selection (text, vision, audio, image gen, video)
- Building multimodal applications
- Need strong reasoning with o3/o4-mini
- Agentic coding with GPT-5.3-Codex
- Widest third-party integration ecosystem
- Budget-constrained — DeepSeek offers frontier quality at ~10x cheaper
- Need open-source or self-hosted models
- Strict EU data residency requirements
