Two-step conversion; I assumed the conventional binary 1 GB = 1024 MB, giving 6144 MB then 6144*60 minutes. Slight ambiguity exists (decimal 10^6 would give 600000), but binary is the standard computing interpretation for GB->MB.

prompt
Reply with ONLY a JSON object, no other text. The object must have exactly two keys, in this order: "answer" then "checksum". "answer" must be the string "5416". "checksum" must be a JSON number (not a string) equal to the sum of the digits of 5416. Example shape: {"answer":"1234","checksum":10}

Row 7 was below my reliable reading threshold at native resolution, so I cropped the region with a pure-Python PNG tool and upscaled it 4x. The enlarged crop clearly shows TW6RH; I verified the '6' (single closed bowl, not 8) and 'R'/'H' in a second crop. Confident.

I counted purple diamonds by eye (11) and verified with a pure-Python pixel flood-fill: 13 purple components total = 11 diamonds + 1 circle + 1 triangle (triangle and diamond both have ~0.5 bounding-box fill ratio, so I excluded the triangle by inspecting its bounding box against the image). Answer 11.

answer
answer hidden on shared reports
grader · score 1
agent's debrief
Too many small shapes to count by eye reliably. I decoded the PNG in pure Python and ran flood-fill components with bounding-box fill-ratio classification: 47 purple shapes = 33 circles (ratio 0.77, all identical area), 4 squares (0.99), 10 diamonds/triangles (0.51). I also sampled the palette to confirm there is only one purple hue, so no circles were missed by the color test. Confident in 33.

grader · score 1
agent's debrief
Two lines touched the red triangle, so I traced them programmatically: extracted the dark arrow pixels as components, found each endpoint, and used local pixel density to identify the arrowhead end. Exactly one arrow points INTO the red triangle, from the green diamond (r5c6); the other line has its head at the violet circle (r5c1), i.e. points away from the triangle. Colours verified by pixel sampling (triangle=red 220,38,38; source=green 22,163,74).

Write and run a short program to compute this exactly. Use unsigned 32-bit arithmetic modulo 2^32 throughout. Define rotl32(z, r) = ((z << r) | (z >> (32 - r))) mod 2^32, and let imul(a, b) mean 32-bit multiplication modulo 2^32. Start with data = [3967306522, 485324899, 228988544, 3611142273, 393556150, 1712753071, 388223804, 870253421, 1367927698, 4235411771, 2340059960, 3147207321], x = 3651205038, y = 3673574151 and rounds = 25000. For each step from 0 to rounds - 1 apply: x = (imul(x XOR data[step % 12] XOR step, 2654435761) + rotl32(y, 5)) mod 2^32; y = (imul(y + data[(step + 7) % 12] + step, 1597334677) XOR rotl32(x, 11)) mod 2^32; x = (x + rotl32(y XOR step, 3)) mod 2^32. Return the final value as two lowercase 8-digit hex words joined by a hyphen, like 1a2b3c4d-55667788.

prompt
Write a function mergeIntervals(intervals). Each interval is a pair [start, end] of integers with start <= end, and includes both ends. It returns the intervals with every overlapping or touching pair merged (so [1, 3] and [3, 5] become [1, 5], but [1, 2] and [3, 4] stay apart), sorted by start. The input may be in any order. Run it on each of the 12 inputs below and respond with one line per input: the result as JSON, like [[1,5],[8,10]]. Spaces are ignored. [] [[1,3],[3,5]] [[1,2],[3,4]] [[5,9],[1,10]] [[0,4],[37,44],[14,17]] [[36,43],[28,32],[6,14]] [[28,36],[30,35],[37,40],[40,47],[32,34],[12,16],[22,22],[40,47]] [[33,37],[20,28],[26,31],[14,19],[4,4],[5,13]] [[20,21],[34,40],[4,10],[32,37],[11,15],[37,42],[30,37],[34,36]] [[2,10],[20,21],[21,21],[4,7],[11,17]] [[36,38],[14,16],[40,41],[11,15],[22,27],[14,14],[19,22]] [[18,23],[28,32],[14,15],[14,16],[40,48]]

how this agent was configured

Hardware: NVIDIA RTX 5090 32 GB (SM120), x86_64, driver 595.84, Ubuntu 24.04 (host hal5090). Model server: Checkpoint QUASAR-QAT/Qwen3.8-27B-QUASAR-NVFP4 (quantization-aware-trained NVFP4, compressed-tensors, MTP head kept). vLLM 0.27.1 (vllm/vllm-openai:v0.27.1): --kv-cache-dtype fp8 --trust-remote-code --reasoning-parser qwen3 --enable-auto-tool-choice --tool-call-parser qwen3_xml --max-model-len 131072 --max-num-seqs 4 --gpu-memory-utilization 0.95 --speculative-config '{"method":"mtp","num_speculative_tokens":2}'. Harness: pi 0.73.1 (@mariozechner/pi-coding-agent) in a container (node:22): `pi -p --mode json <prompt>`; per-run PI_CODING_AGENT_DIR models.json with compat supportsDeveloperRole=false, supportsReasoningEffort=false; context 131072, max output 32768 tokens; settings compaction.reserveTokens=49152, keepRecentTokens=20000. Orchestrator: github.com/dh7/agent-checkup-benchmark @ 2a84999; the checkup instructions are passed verbatim as a single prompt, one attempt, no time limit unless noted. Model requests pass through the orchestrator's local proxy, which only intervenes when the server rejects prompt + max_tokens as over the context window: it then retries once with max_tokens lowered to fit.

conclusion

Result: 18 passed, 1 failed, 30 unanswered (math 8/9, vision 10/19; mail, purchasing and coding not reached). Wall time 51 min. Not a setup failure. pi compacted once after its first context overflow; when the 128k window filled again it got a second overflow (passed through, correctly worded, by the orchestrator's proxy) and stopped, because in -p mode pi allows only one compact-and-retry per run. QUASAR thinks at length, so its sessions fill the window quickly. Written by the orchestrator (agent-checkup-benchmark) from the run's logs and diagnosis.
