New appStrengths & Best Use Cases
GPT-5.5
OpenAI1. Strongest Agentic Coding Model
- State-of-the-art on Terminal-Bench 2.0 (82.7%), Expert-SWE (73.1%), and SWE-Bench Pro (58.6%), outperforming GPT-5.4 on complex coding tasks.
- Holds context across large systems, reasons through ambiguous failures, and carries changes through surrounding codebases with fewer tokens.
2. Higher Intelligence at GPT-5.4 Latency
- Co-designed, trained, and served on NVIDIA GB200/GB300 NVL72 systems to match GPT-5.4 per-token latency while performing at a significantly higher level.
- Uses fewer tokens to complete the same tasks, making it more efficient as well as more capable.
3. Powerful for Knowledge Work & Computer Use
- Scores 84.9% on GDPval (44 occupations) and 78.7% on OSWorld-Verified for autonomous computer operation.
- Excels at generating documents, spreadsheets, and reports; naturally moves across finding information, using tools, and checking output.
4. Scientific Research Co-Scientist
- Leading performance on GeneBench, BixBench, and FrontierMath; helped discover a new proof about Ramsey numbers verified in Lean.
- Strong enough to meaningfully accelerate progress at the frontiers of biomedical and mathematical research.
Grok 3 Mini
xAI1. Lightweight but thoughtful reasoning
- Designed to 'think before responding' with accessible raw thought traces.
- Excellent for logic puzzles, lightweight reasoning, and systematic tasks.
2. Extremely cost-efficient
- Only $0.30 per 1M input tokens and $0.50 per 1M output tokens.
- Cached token support lowers cost to $0.075 per 1M tokens.
3. Fast and responsive
- Optimized for low-latency applications and high-throughput use cases.
- Suitable for chatbots, assistants, and automation flows.
4. Supports modern developer features
- Function calling for tool-augmented workflows.
- Structured outputs for schema-controlled responses.
- Integrates cleanly with agents and pipelines.
5. Large 131K context window
- Can understand and work with long documents, transcripts, or multi-turn sessions.
6. Great for non-domain-heavy tasks
- Useful for summarization, rewriting, extraction, everyday reasoning, and app logic.
- Does not require domain expertise to operate effectively.
7. Compatible with enterprise infrastructure
- Stable rate limits: 480 requests per minute.
- Same API structure as all Grok 3 models.
8. Optional Live Search support
- $25 per 1K sources for real-time search augmentation.
