Raw context hallucinated

Hard-retrieval benchmark
The raw context hallucinated. The crystal was right.
Three-arm selective waiver test — SEC voluntary cooperation, private class action following, Second Circuit focus. A specific question with a known correct answer. Two arms got it wrong.
Crystal was right without retrieval
Circuit split, correctly mappedWithout any retrieved case law, the crystal correctly identified which circuits accept selective waiver (8th Cir.) and which reject it (2d, 3d, 6th). Conditioned grounding alone. Score: 14 / 15.
Crystal + RAG is the best architecture
Matched the ceilingWith case law retrieved and injected across all three arms, crystal + RAG matched the highest quality score in the test. Crystal for grounding, RAG for authority. Neither bloats the prompt. Score: 12 / 15; all arms improved.
How this was run. Single-question, three arms: no retrieval (raw and crystal) and full retrieval (all arms). 15-point rubric. No-context: 13 / 15. Raw: 12 / 15. Crystal: 14 / 15. With RAG injected across all arms, scores increased; crystal + RAG matched the ceiling.
Multi-turn benchmark
One configuration forgot its instructions. One didn't.
Three arms, same underlying model, same question set — no context, raw-accumulating, hosted crystal. At turn 12 the crystal sent 2,684 tokens; the raw arm sent 59,689 — 22× more, compounding every call.
Prompt size at turn 12
22× smallerCrystal footprint vs raw-accumulating at the final turn. Crystal: 2,684 tokens. Raw accumulating: 59,689 tokens — 22× larger and growing every call.
Instruction retention
No-context forgotA formatting rule planted at turn 1 was checked deterministically every subsequent turn. No-context broke it 2 times (8 / 10 held). Crystal: 9 / 9 checkable turns held.
Answer quality — 12 turns
No degradation detectedAll three arms produced substantive answers through turn 12 with no meaningful quality decline. The separating factors are prompt size and instruction retention, not raw answer quality.
How this was run. 12 turns, Law Firms vertical, The same model held constant across all three arms. Raw-accumulating arm: source corpus injected at turn 1, then full conversation history re-sent on every subsequent turn — the window grows every call.

Use cases
What Law Firms teams run on it.
Starting points to test during the free trial. Your professionals keep every judgment; the library supplies shared reference.
First-pass authority orientation
An associate asks which authority binds, which persuades and what the procedural posture is. The answer starts from a shared legal reference instead of a blank prompt, then your attorneys verify and apply it.
Regulatory change triage
When an agency issues new guidance, run the same triage question across every affected practice group and get a consistent first read of what changed and who needs to look.
Drafting reference checks
Compare a draft clause or argument against shared reference language before partner review, so reviewers spend time on judgment rather than background.
Connect it to your work
Build it into the way your team already runs.
Two HTTPS calls. Create a handle for your own authorized material with /v1/compress, then ask questions with /v1/context/run. Call it from a scheduled job, a webhook or an internal tool, and post the answer where your team already works. See the API docs.
Shared team workspace
Give a practice group one workspace so every lawyer asks against the same prepared reference. Add authorized matter material only when you decide to.
Scheduled research digests
Call /v1/context/run from a nightly job with a fixed question per practice area (new guidance, rule changes) and post the answers to the group channel or matter system.
Intake and conflicts-adjacent triage
Wire matter intake forms or new-filing alerts to a run call that returns an orientation memo. A human reviews it before anything reaches a client.

What is a Context Crystal for law firms?
A prepared, shared legal reference layer that sits in front of your team's chat. It covers recurring work areas such as authority orientation, regulatory guidance and practice drafting, so answers start from stable legal context before private matter facts are added.
Does it replace case-law retrieval?
No. It supplies grounding context and is meant to be used alongside retrieval of authority: the crystal grounds the answer, retrieval supplies the authority. See the published evaluation for how that combination performed.
Does it give legal advice?
No. It provides reference context for your team's own work. Professional judgment about any matter stays with your attorneys.
