Model Context Window Comparison: How to Calculate Window and Output Limits, and Avoid Truncation, Latency, and Rate Limiting

Compare the context windows and single-output limits of representative versions like GPT-4o, Claude 3.5 Sonnet, DeepSeek-V3, and Gemini 1.5. This article explains how to calculate token budgets using "input + reserved output ≤ window" and choose the right window tier for your task. When output is truncated, use finish_reason and usage to pinpoint the cause. It also covers how to handle latency, attention decay, and TPM rate limiting caused by long contexts.

DeepSeek V4 API Integration: Pro vs Flash Selection, Call Parameters, and Degradation Verification

DeepSeek V4 series currently includes two independent APIs: V4 Pro (text-only reasoning) and V4.1 Flash (lightweight multimodal). This article explains their architectural differences, model identifiers, OpenAI-compatible integration configuration, Thinking Mode and multimodal call parameters, and four verification methods for silent model swapping and precision degradation risks.
