GPT-OSS 20B vs Grok 3

• Open-weight / Apache 2.0 licensed: you can use, modify, and deploy freely (commercially & academically) under permissive terms.
• Large model size (≈ 21B parameters) with Mixture-of-Experts (MoE) architecture: only ~3.6B parameters active per token, yielding efficient inference.
• Very long context window support: up to ~128 K tokens (or ~131 K tokens per some sources) enabling in-depth reasoning, long documents, or multi-turn context.
• Adjustable reasoning effort: you can trade latency vs quality by tuning “reasoning effort” levels.
• Efficient hardware requirements (for its class): designed to run on a single 16 GB-class GPU or optimized local deployments for lower latency applications.
• Strong for tasks such as reasoning, tool-use, structured output, chain-of-thought debugging: because the model is open and you can inspect its chain of thought.
• Flexibility: since weights are available, you can self-host, fine-tune, or deploy offline, giving more control than closed API models.

1. Strong enterprise-grade reasoning

• Built for deep logical reasoning, structured decision-making, and multi-step analysis.
• Performs exceptionally in domains requiring precision: law, finance, healthcare, and STEM.

2. Excellent at data extraction and summarization

• Optimized for structured extraction from documents, PDFs, tables, and complex text.
• Ideal for enterprise workflows like reporting, compliance automation, or knowledge mining.

3. High-performance coding capabilities

• Excels at code generation, debugging, refactoring, and explaining code.
• Competitive with top-tier coding models for multi-file, long-context code reasoning.

4. Supports function calling and structured outputs

• Integrates cleanly with agent frameworks and external tools.
• Predictable, schema-aligned responses suitable for production systems.

5. Large 131K context window

• Handles long documents, transcripts, contracts, codebases, or multi-document tasks.
• Useful for ingesting highly technical materials in one pass.

6. Efficient cost structure with cached token pricing

• Cached inputs: only $0.75 / 1M tokens, enabling large-scale systems.
• Encourages reuse for powerful retrieval-augmented workflows.

7. Enterprise reliability and availability

• Supported across multiple regions (us-east-1, eu-west-1).
• Consistent rate limits: 600 requests/min.
• Suitable for production-grade apps with stability requirements.

8. Supports advanced search capabilities

• Optional Live Search add-on for real-time knowledge retrieval.
• Pricing: $25 per 1K sources.
