Available models
- GPT
- GPT 5.1 OpenAI Latest, advanced reasoning model for complex tasks
- GPT 5.1 Instant OpenAI Latest, fast, conversational instruction-following model
- GPT 5 medium-fast general purpose; great default for coding + reasoning when a bit of latency is OK.
- Claude
- Sonnet 4.5 Claude’s fast, responsive variant—excellent for interactive chat and frequent short prompts where latency matters most.
- Haiku 4.5 Lightweight model for rapid coding and low-latency workflows.
- Opus 4.1 Premium Model More reasoning depth than Sonnet with moderate latency; solid for multi-file refactors and detailed code edits.
- Gemini 2.5 Pro Strong at large-context and multimodal work; good when you need to reason over many files or combine text with images.
- Grok (XAI) Premium Model Fast, witty, and concise. Well-suited for brainstorming, natural language exploration, and lighter reasoning tasks. Good option when you want responsiveness with personality, though not as strong for very large context or enterprise-grade coding.
- OpenAI o-series (o3, o4-mini) Reasoning-focused models trained to “think longer” before responding.
- o3 – higher-end reasoning for hard problems; good when you want strong tool use and stepwise problem solving.
- o4-mini – smaller, faster while still strong at coding/math/visual tasks; great when you want low latency + good reasoning.
| Model | Speed vs Claude Fast Variants | Best for… | Avoid when… |
|---|---|---|---|
| GPT-5 + GPT-5.1 | Medium — still slower than Claude Sonnet for short prompts. | Complex reasoning, large context (big docs / codebases), tool use, high accuracy tasks. | You need instant feedback / live chat / very short prompts; latency is critical. |
| Claude Sonnet 4.5 + Haiku 4.5 | Fast — very low latency, usually faster than GPT-5. | Interactive UX, short queries, prototyping, frequent lightweight tasks. | Very large context or advanced reasoning beyond its depth. |
| Claude Opus 4.1 | Medium — slower than Sonnet but still often quicker than GPT-5 on many tasks. | Balanced mix of speed and reasoning, multi-file refactors, reliable code edits. | Trivial tasks where Sonnet is sufficient; cost-sensitive workflows. |
| Gemini 2.5 Pro | Moderate — can be slower than Claude for short tasks, but optimized for huge contexts. | Handling very large codebases or documents, multimodal reasoning, context-heavy workflows. | Simple or short prompts (extra context overhead makes it slower); interactive tasks needing instant replies. |
