AI infrastructure tools
The bytes on the wire, the schema the API accepts, and what it costs.
LLM SSE Stream Decoder
Reassemble the message from the wire
Decode a raw LLM SSE stream from the Anthropic or OpenAI API, reassemble the message, and see exactly where a truncated response stopped.
LLM Tool Definition Converter
Anthropic, OpenAI and MCP, both ways
Convert an LLM tool definition between Anthropic, OpenAI and MCP formats, with the fields that have no equivalent named rather than dropped.
LLM JSON Schema Strict Mode Checker
What structured output will refuse
Check whether an LLM JSON schema survives strict structured output: recursion, minimum and maxLength are rejected, additionalProperties must be false.
LLM Context Window Planner
Where the budget runs out
Plan an LLM context window budget across system prompt, tools, history and output, and find where max_tokens truncates the answer instead of the input.
LLM Prompt Caching Planner
Where to put the breakpoint
Plan LLM prompt caching breakpoints and get the break-even read count: cache writes cost 1.25x at five minutes and 2x at one hour, reads cost 0.1x.
LLM API Cost Calculator
The number that matches the invoice
Calculate LLM API cost from your own token volumes and rates, including cache reads and writes, so the number matches the invoice rather than a guess.
LLM Model Cost Comparison
Two models, one workload, your rates
Compare LLM model cost side by side across Anthropic, OpenAI, Google and more, with your own rates overriding the table on either side.
LLM API Rate Limit Planner
Which limit you hit first
Plan around LLM API rate limits: what your request shape costs in tokens per minute, and which of RPM, input TPM or output TPM you hit first.
