LLM Context Windowని ఎలా లెక్కించాలి
LLM Context Window అంటే ఏమిటి?
An LLM context window calculator shows how much of a model's context limit a given amount of text consumes, and estimates the input cost. Context window is the maximum text a model can process at once.
సూత్రం
context_tokens_available = model_context_window - system_prompt_tokens - response_tokens_reserved
- window
- Context window (tokens) — Max tokens the model accepts
- system
- System prompt (tokens) — Tokens used by system instructions
- response
- Max response (tokens) — Tokens reserved for output
- available
- Available for input (tokens) — Tokens left for user input/history
దశల వారీ గైడ్
- 1Context window measured in tokens (1 token ≈ 0.75 words)
- 2Input tokens include both the prompt and any prior conversation
- 3Exceeding context limit causes earlier content to be forgotten
- 4Cost = (context tokens ÷ 1000) × input price per 1K tokens

తరచుగా అడిగే ప్రశ్నలు
What is a context window?
The maximum number of tokens a model can process in a single request. Longer contexts = more memory and latency. Claude 3.5 Sonnet: 200K tokens.
How do I estimate tokens in my prompt?
Roughly: 1 word ≈ 0.75 tokens; 1 line of code ≈ 5–10 tokens. Use official tokenizer tools for precision.
What happens if I exceed the context window?
The request fails or tokens are truncated. Always verify your total token count (system + input + expected output).
