Measured runs, one configuration against another: what we changed, what it cost in tokens, and what each result does not license us to say.

The quirq and Levanto wordmarks side by side, over a lit edge of glass sending four bands of colour to four different heights.Featured17partner studyChoosing the right model per task: a study with Levanto SageA two-round study with Levanto on 90 tasks from XO Space's own development. When Sage chose the model and effort level for each request, and unfinished work was retried once on a stronger layer, quirq AI's XO platform completed 84 of 90 tasks against 83 for an all-Opus baseline, for half the total cost.October 2026 · 20 min read
A single lit edge of glass casting an ordered spectral fan into darkness.07experimentHow the Environment Affects Agent Performance and Token CostA pilot running one coding agent against one fixed task under six escalating levels of project context. Every environment finished, the richest ones spent up to 36 percent fewer tokens, and caching served 88 to 96 percent of the input.June 2026 · 11 min read
A starburst of light rays radiating from a single point in a dark void.08experimentThe Incurious Agent84 controlled runs on environmental curiosity across two coding agents and seven progressively richer environments. Agents read the surface and skip the substance: the curated memory built for the task was opened in 1 of 12 runs.June 2026 · 12 min read
A dense starburst of dispersed rays thrown outward from one bright point in a void.09experimentThe Self-Sufficient AgentWe raised the difficulty until the bare agent should have broken: harder tasks on a real 170-file service. On these tasks it didn't break. With no documentation at all, two coding agents satisfied nine of nine non-obvious functional requirements, identically.June 2026 · 9 min read
Soft ribbons of refracted colour folding over one another against black.10experimentRelevance, Not VolumeTwo operating contracts for a coding agent, matched to the same ~14 KB. The generic one left conformance at its 8% floor; the one carrying a single project-specific rule lifted it to 100% for Codex and 80% for Claude.June 2026 · 8 min read
Fine rays radiating unevenly from a single point of light, thinning into darkness.11experimentCuriosity Comparison Between AgentsA third coding agent joins the context ladder. Gemini tops the curiosity index at 100 against Claude's 60 and Codex's 23, spends 38% of its actions reading files, and is the only one of the three that explores more as the workspace gets richer.June 2026 · 11 min read
A hard white edge splitting a beam into separating bands of colour.12evaluationFable 5 vs Opus 4.8: A Coding-Agent EvaluationA head-to-head on real engineering work through a harness built to make the comparison mean something. Both models passed every gate, so pass/fail did not separate them; Fable led modestly on tool calls and tokens. Only 4 of 10 tasks ran before Fable was suspended.June 2026 · 8 min read
