Focused on repeat AI developer workflows
Plan AI model spend and API throughput.
DevTk.AI now prioritizes the repeat questions AI developers actually need answered: model pricing, token costs, API throughput, rate-limit risk, and structured outputs.
Lead with workflows, not a wall of tools.
The homepage now prioritizes model economics, API throughput, and structured output. MCP stays available through the full tool and resource catalogs.
Model Economics
Check pricing, context windows, and cost range before you wire a model into production.
Throughput & Limits
Estimate RPM, TPM, 429 risk, and budget ceilings before production traffic exposes the bottleneck.
Structured Output
Design the schema first, then test prompt changes with a tighter feedback loop.
Core tools
These are the tools most likely to support search intent and repeated developer use.
AI Model Pricing Calculator
Compare costs across 40+ AI models, including DeepSeek V4 cache-hit pricing. Estimate your monthly spend instantly.
AI API Throughput Planner & Cost Estimator
Estimate sustainable RPM, concurrency, and monthly cost before your AI API traffic hits provider limits.
AI Token Counter
Count tokens for GPT-4o, Claude, Llama, Gemini, and more. See costs instantly.
Free LLM VRAM Calculator — GPU Memory Check
Calculate GPU VRAM requirements for running local LLMs. Check if your GPU can run any model.
JSON Schema Builder
Build JSON schemas visually for LLM structured outputs, function calling, and API validation.
Prompt Diff & Version Compare
Compare two prompt versions side-by-side. See exactly what changed with token counts.
High-intent guides
Content is intentionally narrowed to pricing, model choice, rate limits, agent costs, and structured output.
AI API Pricing Comparison 2026
See the main model pricing deltas on a single page.
OpenAI API Pricing Guide
Track OpenAI model costs without hunting across docs.
Claude API Pricing Guide
Useful when budgeting Anthropic-heavy workloads.
AI Coding Agent Cost
Compare Codex, Claude Code, Cursor-style agents, DeepSeek, and GPT routing costs.
Resources that stay, without owning the homepage
Directories, long-tail tools, and guides are still available, but the information architecture no longer presents everything as equally important.
All tools
Keep the full catalog of 9 tools for long-tail workflows and search entry points.
Models directory
Browse pricing and baseline metadata for 48 tracked models.
AI credits & deals
Find developer-friendly API credits, cloud offers, and tool discounts.
Guides
Concentrate content around pricing, model choice, rate limits, and agent costs.
