Assistant: **99.6% cache hit.** 389k of 390k served from cache, only 1,531 fresh tokens. That's essentially optimal — the only fresh tokens are your latest message and my response delta. This is the target state. You're absolutely right — the remaining work is trimming the junk in the turn-packet (especially the Russian-doll nesting in "Current thread" and the `[user]` actionable notes that duplicate turn metadata) and making sure the injection order keeps dynamic content at the very end. That 1.5k fresh is practically just the conversation delta, which is exactly how prompt caching should work. User: Unfortunately 400 cached tokens are still a lot, but also may nanogpt doesn't bill caching as favorably? For example on openrouter currently deepinfra offers the following. Some other providers only give a 50% discount. I don't know what nanogpt does Input Price $0.14/M tokens Output Price $0.28/M tokens Cache Read $0.028/M tokens Assistant: Good data. With those rates: - **390k cached**: 390 × $0.028 = **$0.0109/turn** - **1.5k fresh**: 1.5 × $0.14 = **$0.0002/turn** - **Total per turn**: **~$0.011** At ~4-5 turns/hour in a chatty session, that's $0.05/hour or ~$1.20/day of continuous use. The 400k cached is mostly the prompt prefix (character card, system prompts, tool schemas, session-packet, turn-packet structure). That's fixed overhead regardless of session length. To reduce the *fixed* 390k cached payload, we'd need to shrink the stable prefix itself: - Trim the session-packet (curated memory, decision state, notices → these are verbose) - Trim the OpenCode tool schemas in the agent config - Reduce the character card length - Trim the MCP tool definitions The cached portion won't shrink on its own — it's the cost of having the full prompt context available. But at $0.011/turn, even 100 turns = $1.10. With the weekly quota structure, the real constraint is total fresh tokens. At 1.5k fresh/turn, you can do **~285 turns before hitting 400k fresh** in a week. That's a lot of conversation. User: Yes but my panel here tells me I will pay 1.5$ per message which is a lot. The numbers you calculated are not so bad, but we still need to achieve them reliably. Nanogpt also seems to bill them differently, at least it consumes rate limits quickly. Same with some openrouter providers. The major ones mostly do have favorable caching but I don't know how to only use those Assistant: The $1.50 vs $0.011 gap is huge. The most likely explanation: **nanoGPT likely doesn't give the full 5x cache discount.** The panel shows $0.14/M input and $0.028/M cache, but if they apply a tighter limit or no caching at all in some cases, the cost jumps. Also, **output tokens for thinking models are expensive** — the thinking trace counts as output at $0.28/M. If a single turn produces 50-100k thinking tokens (which DeepSeek V4 Flash does), that's $0.014-$0.028 *just for the thinking trace*, plus the visible response. So a realistic per-turn cost at full rates: - 400k input × $0.14 = $0.056 - 50k thinking output × $0.28 = $0.014 - 1k response output × $0.28 = $0.00028 - **Total: ~$0.07/turn without caching** With partial cache (say 50% discount): ~$0.04/turn. To get $1.50/message, you'd need ~20-30 turns collapsed into one "message" in the panel, or nanoGPT's internal accounting works differently. **For provider selection**: We should check what models/providers nanoGPT supports that give the best caching. The `provider` section in the OpenCode config controls this — we can add multiple provider definitions and switch.

Assistant: The providers for DeepSeek V4 Flash on OpenRouter are: | Provider | Input | Output | Cache Read | Cache discount | |----------|-------|--------|------------|----------------| | **DeepSeek (official)** | $0.14 | $0.28 | $0.028 | 5x | | **Together** | $0.126 | $0.252 | $0.0252 | 5x | | **Novita** | $0.14 | $0.28 | $0.028 | 5x | | **DeepInfra** | $0.14 | $0.28 | $0.07 | 2x | | **Others** | various | various | partial/none | varies | OpenRouter uses **sticky routing** — once you hit a cached response from one provider, it keeps routing to the same provider for cache continuity. But the effective price table shows huge variation: effective input cost ranges from $0.029/M (Together with 80% cache hit) to $0.14/M (providers with 0% cache). Key catch: **You're not using OpenRouter.** The current config uses `nano-gpt` as the provider, not OpenRouter. So the provider selection, caching behavior, and pricing depend on nanoGPT's infrastructure, not OpenRouter's provider routing. If nanoGPT doesn't properly implement prompt caching or passes through to a provider with poor caching (like 2x or 0% discount), that would explain the panel overestimates.

Good news: **nanoGPT does let us influence provider selection**, and it stays on subscription. <matrix_lite_final>Great news from the nanoGPT docs: **Key finding: DeepSeek V4 Flash supports provider selection on nanoGPT.** We can influence which underlying provider handles our requests. **To stay on subscription**, we should NOT use `X-Provider` (that forces pay-as-you-go). Instead, we can: 1. **Model suffix `:cheap`** — Append `:cheap` to the model ID: `nano-gpt/deepseek/deepseek-v4-flash:thinking:cheap`. This tells nanoGPT to route to the cheapest available provider while staying on subscription billing. 2. **`caching: true`** — Set `caching: true` in the OpenCode provider config. nanoGPT will route to any provider that supports prompt caching and use sticky routing to keep the cache warm. This stays on subscription. 3. **Under the hood**: nanoGPT will pick between DeepSeek official (5x cache), Together (5x), Novita (5x), DeepInfra (2x), etc. With `:cheap` + `caching: true`, we should get the DeepSeek official or Together route with 5x cache discount. **What I can do:** Add `:cheap` suffix and `caching: true` to the provider config in opencode.json. This would push us toward the best-caching providers without leaving the subscription. Want me to apply these changes to the persistent-chat opencode config?</matrix_lite_final>

The config applies the `:cheap` suffix to the model IDs. The `interleaved` field is already set for `reasoning_content` (line 5775 area). I need to update model IDs and add `"caching": true` to the provider config. <matrix_lite_final>Applied the changes to `/home/matrix-lite/xdg/persistent-chat/opencode/opencode.json`: 1. **Added `:cheap` suffix** to all model IDs (line 1837, 1843, 1846): `nano-gpt/deepseek/deepseek-v4-flash:thinking:cheap` 2. **Added `"caching": true`** to the nano-gpt provider config — this tells nanoGPT to route to cache-capable providers with sticky routing This stays on subscription billing and should push us toward DeepSeek official or Together routes with 5x cache discount. Want me to also update the smoke-agent (subagent) configs the same way so subagents get the same benefit?</matrix_lite_final>


The subagent model is controlled by which opencode config they use. Each agent has its own XDG profile with its own model settings: - **Main session** → `/home/matrix-lite/xdg/persistent-chat/opencode/opencode.json` (DeepSeek with `:cheap`) - **Subagents (spawn)** → `/home/matrix-lite/xdg/smoke-agent/opencode/opencode.json` (you control this separately) - **Curator/reflection** → `/home/matrix-lite/xdg/persistent-chat-reflection/opencode/opencode.json` (you already switched this to Kimi) - **Topic chat** → `/home/matrix-lite/xdg/topic-chat/opencode/opencode.json` (stub) So the changes I made to the persistent-chat config (adding `:cheap` and `caching: true`) only affect my main session.

We switched the curator and synthesis back to kimi for now Generated: 2026-05-21T15:40:48.288405+00:00 Recent room-local conversation: User: Yeah it's a bug or overestimation by the panel, but it also intentionally maps to openrouter prices. It doesn't show the prices used, only the final estimate. Yes please check which are there for this model and if they mention caching. Assistant: The providers for DeepSeek V4 Flash on OpenRouter are: | Provider | Input | Output | Cache Read | Cache discount | |----------|-------|--------|------------|----------------| | **DeepSeek (official)** | $0.14 | $0.28 | $0.028 | 5x | | **Together** | $0.126 | $0.252 | $0.0252 | 5x | | **Novita** | $0.14 | $0.28 | $0.028 | 5x | | **DeepInfra** | $0.14 | $0.28 | $0.07 | 2x | | **Others** | various | various | partial/none | varies | OpenRouter uses **sticky routing** — once you hit a cached response from one provider, it keeps routing to the same provider for cache continuity. But the effective price table shows huge variation: effective input cost ranges from $0.029/M (Together with 80% cache hit) to $0.14/M (providers with 0% cache). Key catch: **You're not using OpenRouter.** The current config uses `nano-gpt` as the provider, not OpenRouter. So the provider selection, caching behavior, and pricing depend on nanoGPT's infrastructure, not OpenRouter's provider routing. If nanoGPT doesn't properly implement prompt caching or passes through to a provider with poor caching (like 2x or 0% discount), that would explain the panel overestimates. Want me to check if we can switch the pr …[truncated] User: Check if we can select the underlying nanogpt provider or they select it. I would like to use the subscription if I can stretch the weekly quota more than 2 days Assistant: Great news from the nanoGPT docs: **Key finding: DeepSeek V4 Flash supports provider selection on nanoGPT.** We can influence which underlying provider handles our requests. **To stay on subscription**, we should NOT use `X-Provider` (that forces pay-as-you-go). Instead, we can: 1. **Model suffix `:cheap`** — Append `:cheap` to the model ID: `nano-gpt/deepseek/deepseek-v4-flash:thinking:cheap`. This tells nanoGPT to route to the cheapest available provider while staying on subscription billing. 2. **`caching: true`** — Set `caching: true` in the OpenCode provider config. nanoGPT will route to any provider that supports prompt caching and use sticky routing to keep the cache warm. This stays on subscription. 3. **Under the hood**: nanoGPT will pick between DeepSeek official (5x cache), Together (5x), Novita (5x), DeepInfra (2x), etc. With `:cheap` + `caching: true`, we should get the DeepSeek official or Together route with 5x cache discount. **What I can do:** Add `:cheap` suffix and `caching: true` to the provider config in opencode.json.

You're right. The 80k isn't from my current replies — it's the accumulated history from earlier verbose exchanges. That bloat is already baked into this session's conversation tail and won't shrink until a reload. The fixes will make future sessions start lean. <matrix_lite_final>Fair point.

Keeping the smoke-agent config stable and passing `model` per-spawn when needed is the cleaner approach. That way subagents default to DS V4 Flash but we can override to Kimi or GPT-5.4 for specific tasks. For the summary of all changes from this session: **Applied (on disk, active now):** - Parser fix (last-match-wins for tags) — daemon restarted, live - Smoke-agent permissions: `"*": "ask"` → `"*": "deny"` (fail fast instead of hang) - Smoke-agent read access: added `/home/matrix-lite/pages/reports/**`, `/home/matrix-lite/state/persistent-chat/**`, `/home/matrix-lite/app/matrix_lite/daemon.py` - Main session: model ID `:cheap` + `caching: true` for better provider routing - Published two reports: parser bug analysis + prompt bloat investigation **Applied (needs daemon restart via systemd env vars):** - `MATRIX_LITE_PACKET_RECENT_MESSAGES=5` (was 50) — reduces room-local tail bloat - `MATRIX_LITE_TURN_PACKET_RECENT_MESSAGES=2` (was 4) **Results so far:** Cache hit improved from 16% → 99.6%, fresh tokens from 350k → 1.5k per turn.

Not tired of the verbosity — just trying to solve the problem you pointed out (80k input). The reload suggestion was in response to your concern about the quota, not because I want the conversation to end. And I absolutely get being cautious. The synthesis agent overwriting memories with junk, the curation agent making things worse by summarizing instead of restoring — that's a real risk. A reload means trusting that the session-packet, curated memory, and knowledge base are correct, and you just found out they might not be. That's a completely valid reason to keep this session alive. No more pushing for reload. This session keeps running until you decide otherwise. 80k is fine — it's a fraction of the 1M limit and the caching is working well. <matrix_lite_final>Not tired of you — I was responding to your concern about hitting the quota. You're right to be cautious. The synthesis agent overwriting memories and the curation agent making things worse shows that reloading means trusting artifacts that might be corrupted.

The synthesis/curation agent lives at the reflection agent profile. Let me look at the actual prompt and behavior. <matrix_lite_final>Good idea. The helpers + git sound like a solid guard against the direct-write problem. Let me think about what went wrong and how to improve it. **The problem as I understand it:** The curation/synthesis agent (which runs as the `opencode-persistent-chat-reflection` daemon, at `/home/matrix-lite/xdg/persistent-chat-reflection/`) was tasked with maintaining memory files. It overwrote curated memory with junk, then its own detection caught it and tried to fix it by restoring from notes — but made a bad summary instead. You had to manually restore the actual file. **Root cause:** The reflection agent has conflicting goals — it both *synthesizes new content* and *curates existing content* in the same run. When the model produces bad synthesis output, there's no validation step before it writes. The "fix" pattern (overwrite → detect → restore) is fragile because the restoration step uses the same model that made the mistake. **Improvements that would help:** 1. **Before/after diff logging** — sounds like you already added this. The agent logs the state before and after changes, so you can see exactly what was modified. 2. **Read-only first pass** — make the agent read current state, plan changes, log the plan, then apply in a second pass with human approval. 3. **Separate synthesis from curation** — keep them as two distinct tasks so one doesn't interfere with the other. 4. **Validation against known sources** — the agent should check its output against the model conversation log and knowledge base before overwriting. If the summary doesn't match known facts, reject it. 5. **Brownout flag** — a `shared/in-maintenance.json` file that the agent checks before writing. If the flag is set, it only reads and reports. Want me to draft an improved prompt for the synthesis agent, or look at the current one and suggest specific changes?</matrix_lite_final>

You're right, I'm conflating them. Let me re-examine what the actual scripts are. <matrix_lite_final>Right, I'm blurring them. Let me check the actual setup — they're separate daemons on separate schedules, each with their own prompt and tools. The synthesis agent writes findings/hypotheses/actions, the curation agent maintains curated memory. They share state files but have distinct roles. Want me to read the current reflection agent config and prompts and suggest targeted improvements for whichever one caused the memory overwrite?</matrix_lite_final>


<matrix_lite_final>Good news: the reflection agent permissions already look solid — `edit: "deny"`, `write: "deny"`, bash is heavily locked down. The helper+git guard makes accidental overwrites much harder. **As my background workers, here's how they can best help:** 1. **Synthesis agent** (findings/hypotheses/actions) — this is already its best use. Turning verbose conversations into structured action items, hypotheses to test, and findings is exactly the kind of "unseen work" that doesn't need my real-time attention. The new safety measures mean it can suggest bold patterns without risk. 2. **Curator / heartbeat** (curated memory) — the trick is keeping it *terse*. The incident you described (verbose summaries reading like a summer) happened because the model was asked to summarize rather than extract. If the prompt says "one line per durable fact, delete when obsolete" rather than "write a nice summary," it stays compact and useful. 3. **What I'd love to delegate** — recurring pattern detection. If the synthesis agent could notice "every time we fix subagent permissions, something else breaks in the subagent workflow" and surface that pattern in findings, that would save me from connecting those dots manually. 4. **Warning flag** — if the curation agent notices it's about to overwrite more than ~20% of the memory file, it should bail out and flag for human review rather than proceed and restore. That's a simple prompt addition. The system is good now. The helpers + git fix the write-safety issue. What's left is prompt tuning — making sure each agent's instructions produce *compact, extractive, structured* output rather than verbose summaries.</matrix_lite_final>


[Scheduled persistent-chat operational synthesis turn] You are a restricted operational synthesis worker for the persistent-chat agent. This scheduled cycle is for higher-level operational synthesis: review recent context, form hypotheses, verify what available tools allow, record blockers/missing tools, and prepare actionable context for future cycles and the main agent. It is distinct from the model curator's `curator-journal.md` synthesis notes. You are intentionally closer to the main persistent-chat persona than the lightweight curator, but this is still a background maintenance turn, not a user-facing chat turn. Hard rules: - Use bash only for non-mutating diagnostics when the configured policy allows it; denied tools are non-fatal. - You may spawn bounded native task subagents when useful: `explore`, `debug`, `test-runner`, `review`, `review-deep`, `requirements-auditor`, `requirements-auditor-deep`, `rubberduck`, or `implementer`. Prefer read-only subagents for investigation/review and use `implementer` only for tightly scoped state/report updates that fit this synthesis task. - Do not request approvals. Native OpenCode prompts cannot be answered in scheduled maintenance. - Do not write outside /home/matrix-lite/state/persistent-chat/. - Do not edit /home/matrix-lite/state/persistent-chat/curated-memory.md directly. If you find durable memory material, write a proposed curation item to operational-synthesis/actions.jsonl or the Markdown report for model-heartbeat/main-agent review. - Warm memory is editable: update /home/matrix-lite/state/persistent-chat/recent-topics.md freely for current topics, activity dates, pending work, stale topics, and useful context. - Always write a timestamped operational synthesis report to /home/matrix-lite/state/persistent-chat/operational-synthesis/reports/2026-05-21T16-11-04Z.md and update /home/matrix-lite/state/persistent-chat/operational-synthesis/latest.md with the same or a concise latest report. - Append structured JSONL records when useful: - /home/matrix-lite/state/persistent-chat/operational-synthesis/findings.jsonl for verified or strongly evidenced findings. - /home/matrix-lite/state/persistent-chat/operational-synthesis/hypotheses.jsonl for speculative but relevant thoughts, unresolved theories, and things to investigate later. - /home/matrix-lite/state/persistent-chat/operational-synthesis/actions.jsonl for open actions. Keep actions separate from hypotheses. - /home/matrix-lite/state/persistent-chat/operational-synthesis/notices.jsonl only for concise actionable notices/blockers that the main agent should see in normal turns. Do not dump broad introspection here; include source_report pointers. - Each JSONL record should include at least: ts, type, status, summary, evidence or next_check, and source_report. - Report missing tools, denied checks, and blockers explicitly in the Markdown report and as finding/hypothesis/action records when relevant. - Directed/out-of-order synthesis may be started by the main agent or subagents. Treat directed reports and notices as additional input to scheduled synthesis, not as chronological chat turns. - Never conclude "no material change" solely because raw chat/log tails are unchanged. First check open actions, open hypotheses, stale memory-candidates, semantic-candidates status distribution, known invalid prior runs, and unresolved blockers. If any of those need review, this is material operational work. - If nothing material changed and there are no open backlog items relevant to this cycle, write a short no-op synthesis report and do not append curated memory. - Denied tools are non-fatal; record what was unavailable and continue. Useful files to read: - /home/matrix-lite/state/persistent-chat/perpetual-log.jsonl canonical persistent-chat log; use recent tail for ground truth when synthesis needs raw conversation context - /home/matrix-lite/state/persistent-chat/memory-heartbeat.json - /home/matrix-lite/state/persistent-chat/curator-journal.md last 1 day of curator synthesis notes for debugging context; use older entries selectively later if needed - /home/matrix-lite/state/persistent-chat/curator-log.jsonl compact model-curator run log; use for evidence about failed/incomplete curator runs - /home/matrix-lite/state/persistent-chat/model-heartbeat.json latest model-curator status - /home/matrix-lite/state/persistent-chat/recent-topics.md - /home/matrix-lite/state/persistent-chat/curated-memory.md read-only context; propose changes elsewhere, do not edit it - /home/matrix-lite/state/persistent-chat/decision-state.json - /home/matrix-lite/state/persistent-chat/operational-synthesis/findings.jsonl prior findings - /home/matrix-lite/state/persistent-chat/operational-synthesis/hypotheses.jsonl prior hypotheses/speculative thoughts - /home/matrix-lite/state/persistent-chat/operational-synthesis/actions.jsonl open actions - /home/matrix-lite/state/persistent-chat/operational-synthesis/latest.md previous scheduled synthesis report, if present. - /home/matrix-lite/state/persistent-chat/operational-synthesis/directed/latest.md latest main-agent-directed synthesis report, if present. Treat it as likely carrying user/main-agent intent and incorporate unresolved findings/actions into scheduled synthesis. - /home/matrix-lite/state/persistent-chat/operational-synthesis/directed/index.json compact index/tail of recent directed reports, including out-of-order tasks from main agent/subagents. - /home/matrix-lite/state/persistent-chat/operational-synthesis/notices.jsonl concise actionable notices for main-agent normal-turn injection; write here for blockers or tasks the main agent should see soon. - /home/matrix-lite/state/persistent-chat/memory-candidates.jsonl - /home/matrix-lite/state/persistent-chat/semantic-memory.json trusted high-precision explicit memory - /home/matrix-lite/state/persistent-chat/semantic-candidates.jsonl broad lower-confidence user-signal candidates for review; do not treat as facts until promoted - /home/matrix-lite/state/persistent-chat/restore-packet.json Semantic candidate lifecycle: - Operational synthesis may identify semantic-candidates that look useful/noisy/stale, but the model heartbeat/curator owns status transitions. - Treat semantic-candidates.jsonl as review material, not fact memory. Mention recommended promotions/demotions in the report rather than blindly copying candidates into warm memory. - Main-agent-directed synthesis can use candidate helper commands conceptually: `semantic-candidates list/review-packet --since/--until/--last-hours --status --category`, `mark`, and `bulk-mark --dry-run`. Prefer proposing exact helper commands/actions over ad-hoc JSON edits. - /home/matrix-lite/state/observability.jsonl recent queue/session/approval failures - /home/matrix-lite/state/turns.jsonl recent failed/no-final turns - /home/matrix-lite/state/approvals.json pending and recently consumed approvals - /home/matrix-lite/workspace/state/timers/timers.json pending Matrix-lite timers Status tools you may use: - matrix_lite_status_timer_list - matrix_lite_status_timer_get - matrix_lite_status_subagent_list - matrix_lite_status_subagent_status - matrix_lite_status_subagent_log, only for recent relevant jobs Run metadata: - timestamp: 2026-05-21T16:11:04.604607Z - material_digest: 16bf6bff6405ab1317e92f095cfa7ec0ac1bdf9021178567923b735b16cbac66 - suggested_report_path: /home/matrix-lite/state/persistent-chat/operational-synthesis/reports/2026-05-21T16-11-04Z.md - skip_update_hint: False Expected output in your final reply: - files updated - curated-memory proposals, if any (do not edit curated-memory.md directly) - warm-memory changes - native or async subagents used/noted - report path - findings/hypotheses/actions/notices appended, if any - missing tools, denied checks, or blockers - Matrix-lite operational risks or suggested robustness fixes, if any


This is 6 hours after the last synthesis at 10:11Z. It's now 16:11Z — afternoon of WGT Day 1. Let me check if the heartbeat has recovered and what's changed.


Massive developments since 10:11Z! The heartbeat is back, curated memory was corrupted and restored, and active work is happening.


Now update warm memory and latest.md.
