"outputTokens": 121
}togetherai:moonshotai/Kimi-K3

streaming-structure
okAsserts a streaming call captures events that reconstruct into the final text.
- mode=streaming, 23 stream events, 1 text block(s), 35 chars.
Result
{
"mode": "streaming",
"streamEventCount": 23,
"textBlocks": 1,
"textLen": 35

complete-stream-parity
okSame prompt via stream() and complete() both return valid, matching results.
- stream="Paris" · complete="Paris"
Result
{
"streamText": "Paris",
"completeText": "Paris"

reasoning-conformance
okAsserts the model's reasoning knob behaves as its reasoning-config declares.
- Class (from reasoning-config): toggleable.
- off: out=332 · mid: out=418 (rt=181).
Result
{
"class": "toggleable",
"mode": "deterministic",
"offOutputTokens": 332,

single-tool-call
okOffers a calculator tool and checks the model calls it for an arithmetic question.
- Called "multiply" with args {"a":23,"b":17}.
Result
{
"toolCalled": true,
"toolName": "multiply",
"args": {
"a": 23,
"b": 17
},
"correct": true
}togetherai:moonshotai/Kimi-K3
tool-loop
okForces a tool call, feeds the result back, and checks the continuation uses it.
- step1 (required): multiply({"a":23,"b":17}) → step2: "23 multiplied by 17 is 391."
Result
{
"toolName": "multiply",
"args": {
"a": 23,
"b": 17
},
"product": 391,
"continuation": "23 multiplied by 17 is 391.",
"usesResult": true,
"forced": true

web-search
okEnables server-side web search and checks invocation counts, the per-request cost surcharge, and provider-executed output blocks.
- Skipped: model does not support the catalog's web_search tool version.
Result
{
"skipped": "no server-side web search support"
}reasoning-tool-continuity
okReasoning model: continuity token captured on a tool call and replayed so the follow-up succeeds.
- reasoned=true, none token —; follow-up → "**Balance for account `acme-42`:** $1,234.00 **Growth calculation (5%"
Result
{
"signatureType": "none",
"tokenCaptured": false,
"reasoned": true,
"answered": true,
"continuation": "**Balance for account `acme-42`:** $1,234.00\n\n**Growth calculation (5% annually, compounded for 7 years):**\n\n$$\\text{Future Value} = \\$1,234"

prompt-cache
okRepeat a large prefix; assert cache-read tokens are reported and cost drops.
- Skipped: provider has no (known) prompt-cache reporting.
Result
{
"skipped": "cacheStyle=none"
}json-output
okRequests a strict JSON object and checks it parses with the required keys.
- Output parsed as JSON.
- All required keys present.
- Output is bare JSON (no leading prose/fence).
Result
{
"parsed": {
"name": "Anthropic",
"founded": 2021,
"headquarters": "San Francisco, California, United States"
},

summarize-memex
okSummarizes an ~11k-token essay to ~500 words (long input, reasoning minimized).
- Read ~10274 input tokens, wrote 457 words (627 output tokens) in 11785ms.
Result
{
"wordCount": 457,
"inputTokens": 10274,
"outputTokens": 627,
"latencyMs": 11785
}togetherai:moonshotai/Kimi-K3
truncation
okTiny maxTokens on a long prompt yields finishReason:"length".
- finishReason=length, out=100 tokens.
Result
{
"finishReason": "length",
"outputTokens": 100
}togetherai:moonshotai/Kimi-K3
streaming-only-rejection
okStreaming-only models reject complete(); all others accept it.
- streamingOnly=false; complete() succeeded.
Result
{
"streamingOnly": false,
"completeThrew": false
}abort
okA pre-aborted signal rejects the call (abort is threaded + honored).
- pre-aborted signal → rejected (AbortError).
Result
{
"rejected": true,
"errorName": "AbortError"
