{"slug": "show-hn-ai-model-token-cost-and-context-window-estimator", "title": "Show HN: AI Model Token Cost and Context Window Estimator", "summary": "A developer released a Show HN tool that estimates token counts, context-window fit, and API costs across multiple large language models, including a side-by-side comparison matrix of context limits and per-1M-token input and output pricing. The estimator accepts TXT, JSON, MD, CSV, or PDF files, reports usage against a 128,000-token context limit, and projects costs for a single API request and a 100,000-request production batch. The tool targets teams planning large-scale prompt deployments who need to compare flagship and lightweight LLMs on cost and capacity before committing.", "body_md": "**0** Words:\n\n**0**\n\n**TXT, JSON, MD, CSV, or PDF** files here or click to browse\n\n**0**/ 128,000 tokens 0.0%\n\nYour prompt comfortably fits within this model's capacity limit.\n\n## Production Multi-Run Batch Estimator\n\nProject total operational cost when deploying this prompt configuration at scale.\n\n## Side-by-Side Model Comparison Matrix\n\nComparing current token metrics across flagship and lightweight LLMs.\n\n| Model | Provider | Context Limit | Input / 1M | Output / 1M | 1 API Request | 100k Production Batch | \n|---|---|---|---|---|---|---|", "url": "https://wpnews.pro/news/show-hn-ai-model-token-cost-and-context-window-estimator", "canonical_source": "https://ai-token-estimator.pages.dev/", "published_at": "2026-11-03 18:09:36+00:00", "updated_at": "2026-11-03 18:21:58.787883+00:00", "lang": "en", "topics": ["ai-tools", "large-language-models", "ai-infrastructure", "developer-tools"], "entities": ["Show HN"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-ai-model-token-cost-and-context-window-estimator", "markdown": "https://wpnews.pro/news/show-hn-ai-model-token-cost-and-context-window-estimator.md", "text": "https://wpnews.pro/news/show-hn-ai-model-token-cost-and-context-window-estimator.txt", "jsonld": "https://wpnews.pro/news/show-hn-ai-model-token-cost-and-context-window-estimator.jsonld"}}
