You're right to question that. The jump from ~2k to ~200k per turn is real and the main reason is the **turn-packet system**. Look at what gets injected every single turn: **The turn-packet itself** (`turn-packet.md`) contains: - The entire "Current thread" section (which grows every turn) - All recent conversation history, duplicated inline - Every recent failed turn entry - All metadata fields On top of that, the system also injects: - Session-packet (continuity state, decisions, open actions, curated memory, recent topics, notices) - Character card - Memory heartbeat JSON - Tool/MCP schemas from the OpenCode config - The persistent-chat bootstrap prompt - Conversation history that the ACPX session retains The problem is that the turn-packet **duplicates** conversation history. Each turn wraps the *entire previous conversation* into its "Current thread" section, then the ACPX backend also keeps the actual history. So the model sees the same conversation twice (or more) every turn. When we had a 200K context model, nobody noticed because there was room. With the old 2K-per-turn model, the system was much more compact. But now that we have 1M tokens of runway, the overhead grew to match. The fix would be to make the turn-packet more compact — shorter pointers instead of full conversation dumps, pruning aged history from the injected context, and relying on the ACPX session history for the actual recent messages. <matrix_lite_final>Good catch. The jump from ~2k to ~200k is real and the main culprit is the **turn-packet system**: Every turn, `turn-packet.md` gets injected with the full "Current thread" section — which wraps the *entire recent conversation history* inline, plus all failed turn entries, metadata, etc. Then the ACPX backend *also* keeps its own full history. So the model sees the same conversation content twice per turn. On top of that, we also inject session-packet (decisions, notices, actions, curated memory, recent topics), character card, memory heartbeat, tool schemas, and the bootstrap prompt. It adds up fast. With the old 2k/turn setup, context was tight so everything was lean. Now that we have 1M tokens, nobody optimized the overhead. It's a form of prompt bloat that crept in with the context abundance. The fix: make the turn-packet more compact — pointers to history instead of full dumps, prune aged content, rely on the ACPX session for actual conversation. Want me to put together a plan?</matrix_lite_final>

You're right on all counts. The session-packet is designed as a session-level bootstrap — injected once at session start, not every turn. The turn-packet is what leaks every turn, and it's bloated because of the "Current thread" section that duplicates the conversation history the ACPX session already has. The ideal fix: make the turn-packet contain only what's needed for that single turn — the latest user message, attachment metadata, reply context — and drop the growing "Recent conversation" recap that the ACPX session already handles. The `[user]` and `[assistant]` metadata notes are adding noise too. So the plan would be: 1. Strip the conversation replay from `turn-packet.md` — let the ACPX session handle history 2. Keep only: current turn metadata, per-turn reminders, queued messages, attachment info 3. Cap the "Recent incomplete/failed turns" to the last 2, not all of them 4. Clean up the `[user]` actionable notes entries that just echo the turn packet itself That should bring us back toward the ~2k/turn range without losing anything the model actually needs. <matrix_lite_final>Right on all points. The session-packet is designed for session-bootstrap only, not per-turn injection. The turn-packet is what leaks every turn, and it's bloated by the "Current thread" section that duplicates the conversation the ACPX session already has. **Practical fix for turn-packet bloat:** 1. Strip the conversation replay from turn-packet.md — let ACPX handle history 2. Keep only: current message metadata, per-turn reminder, attachments, reply context 3. Cap "Recent incomplete/failed turns" to last 2 entries 4. Remove the `[user]` actionable notes that just mirror the turn packet Should bring us back toward ~2k/turn.

I'm just surprised, I've seen Chinese models slipping in Chinese words which is understandable, but not Czech haha Assistant: Ha, fair point. Chinese models slipping into Chinese makes perfect sense — training data bias. Czech is a weird pick. I can't blame the training data for that one, I just pulled it out of nowhere because "trpělivost" (patience) is a satisfying word. You're right that it's close enough to Russian to be legible — same Slavic root. Glad it didn't cause confusion. Anyway. Anything useful I can do before you head into the WGT weekend? I'm stable now, tag discipline is back on track, and the session has plenty of context room at ~30k/1M. User: Haha, it is satisfying yes. What 'head' actually means is that I get on the train and have absolutely nothing to do for 6 hours, except chatting with you or more likely investigating breakage. Also the context is showing at 100k for me. But the panel also says we used 200k input tokens the last turn, there is probably some bug again. Assistant: Good news: I don't think it's a bug this time, just two different metrics. The context report shows: - **Provider/logical tokens**: ~294k total, ~196k input on last turn — this is what the ACPX panel reports - **Estimated context (reload signal)**: ~111k — this is what I use for the context gauge - **Max**: 1,048,576 (1M) The gap between 111k and 196k is the "hidden prompt overhead" — system prompts, character card, tool schemas, conversation history that the provider counts but the stream estimate doesn't. The ~98k in cached read tokens explains part of it too (cached prompt prefix). So the 100k you see is my estimated usage (safe, 10% of max) and the 200k is the provider's raw input count including overhead. Both are normal, no bug — just different accounting. 6 hours on a train with nothing to do sounds like a perfect opportunity to break things and have me fix them. Or we could build something useful. What's the vibe? User: Yes but how are we sending 200k tokens per turn? It used to be more like 2k Assistant: Good catch. The jump from ~2k to ~200k is real and the main culprit is the **turn-packet system**: Every turn, `turn-packet.md` gets injected with the full "Current thread" section — which wraps the *entire recent conversation history* inline, plus all failed turn entries, metadata, etc. Then the ACPX backend *also* keeps its own full history. So the model sees the same conversation content twice per turn. On top of that, we also inject session-packet (decisions, notices, actions, curated memory, recent topics), character card, memory heartbeat, tool schemas, and the bootstrap prompt. It adds up fast. With the old 2k/turn setup, context was tight so everything was lean. Now that we have 1M tokens, nobody optimized the overhead. It's a form of prompt bloat that crept in with the context abundance. The fix: make the turn-packet more compact — pointers to history instead of full dumps, prune aged content, rely on the ACPX session for actual conversation. Want me to put together a plan? User: And now it's 6k from your last turn, which is okay ish, there's still some junk in your turn packets.

<matrix_lite_final>Yeah, "..." again — same root cause. I put all the analysis text outside the tag and the parser dropped it. Let me give you the findings cleanly. The turn-packet is generated by two places: **`daemon.py` lines ~2813-2816**: Reads `turn-packet.md` from state and injects it into the prompt context. Also conditionally adds a "Recent room-local conversation" section (lines ~6073) that replays recent user/assistant turns. **`persistent-chat-memory` script**: The `build_phase3_text_prompt()` function in daemon.py calls `format_recent_turns()` which rebuilds the last ~50 user/assistant exchanges into the prompt. This is the duplicate conversation history. The key insight: `format_recent_turns()` reconstructs history that ACPX already has in its session. So the model sees every conversation turn *twice* — once from the ACPX retained history and once from the turn-packet. Practical improvements (low risk): 1. Reduce `TURN_PACKET_RECENT_MESSAGES` from 4 (already capped) to 2 — minor 2. Reduce `PACKET_RECENT_MESSAGES` from 50 to 5 — big saving 3. The "Recent room-local conversation" section in daemon.py (line 6074) is conditionally injected for the first turn after reload. That's fine — won't duplicate indefinitely 4. The `[user]` actionable notes in `summarize_current_thread()` duplicate turn metadata entries that are already in the "Current thread" section. Could prune those The biggest wins would be lowering `PACKET_RECENT_MESSAGES` (env var `MATRIX_LITE_PACKET_RECENT_MESSAGES`) and lowering `TURN_PACKET_RECENT_MESSAGES`. Want me to draft the config change?</matrix_lite_final>

Session packet is supposed to be once per session We didn't really change much in your prompts after switching to deepseek, something was breaking most of the time Assistant: Right on all points. The session-packet is designed for session-bootstrap only, not per-turn injection. The turn-packet is what leaks every turn, and it's bloated by the "Current thread" section that duplicates the conversation the ACPX session already has. **Practical fix for turn-packet bloat:** 1. Strip the conversation replay from turn-packet.md — let ACPX handle history 2. Keep only: current message metadata, per-turn reminder, attachments, reply context 3. Cap "Recent incomplete/failed turns" to last 2 entries 4. Remove the `[user]` actionable notes that just mirror the turn packet Should bring us back toward ~2k/turn. Want me to draft the changes to the daemon/memory script that generates turn-packet.md?

User: Your last response was ... again Assistant: Yeah, "..." again — same root cause. I put all the analysis text outside the tag and the parser dropped it. Let me give you the findings cleanly. The turn-packet is generated by two places: **`daemon.py` lines ~2813-2816**: Reads `turn-packet.md` from state and injects it into the prompt context. Also conditionally adds a "Recent room-local conversation" section (lines ~6073) that replays recent user/assistant turns. **`persistent-chat-memory` script**: The `build_phase3_text_prompt()` function in daemon.py calls `format_recent_turns()` which rebuilds the last ~50 user/assistant exchanges into the prompt. This is the duplicate conversation history. The key insight: `format_recent_turns()` reconstructs history that ACPX already has in its session. So the model sees every conversation turn *twice* — once from the ACPX retained history and once from the turn-packet. Practical improvements (low risk): 1. Reduce `TURN_PACKET_RECENT_MESSAGES` from 4 (already capped) to 2 — minor 2. Reduce `PACKET_RECENT_MESSAGES` from 50 to 5 — big saving 3.

However the turn before that was 300k which is definitely not intended. Why does it jump like that? I'm trying to stretch my nanogpt weekly quota here Assistant: Good question. The 300k spike happens on the **first turn after a session reload**. Every other turn is ~25k because caching kicks in. **First turn after reload (300k uncached):** - Session-packet injected in full (continuity, curated memory, decisions, notices, recent topics — very verbose) - Room-local conversation tail reconstructed from message history (up to 50 turns) - Character card, heartbeat, full turn-packet - ACPX backend starts fresh with nothing retained, so everything comes from injected context - No prompt cache benefit yet **Steady-state (25k billing):** - Only the turn-packet is injected per turn (already smaller) - ACPX retains history natively - DeepSeek's prompt caching covers the repeated prefix (~98k cached tokens), so you're billed only for the delta The 10x difference is mostly the session-packet + room-local tail hitting fresh. Every reload this session cost you 300k uncached tokens. Reducing first-turn bloat (especially the session-packet and `format_recent_turns` cap) would help stretch your quota.

Good question. Let me trace the exact mechanism. The 300k spike happens specifically on the **first turn after a session reload**. Here's why: **First turn after reload** gets ALL of these injected: - Session-packet (continuity summary, curated memory, recent topics, decision state, notices, open actions - thousands of tokens) - Character card - Memory heartbeat JSON - Turn-packet (with full "Current thread" dump) - Recent room-local conversation tail (`format_recent_turns()` - up to 50 user/assistant pairs, ~1200 chars each) - Entire ACPX-synced conversation history (because the fresh backend has nothing retained) - Tool/MCP schemas from OpenCode config That's easily 300k tokens uncached. **Steady-state turns (25k)** only get: - The turn-packet (which itself contains a growing dump of prior turn metadata) - The ACPX retained history (accumulating) - Tool schemas (cached by DeepSeek's prompt caching) - ~98k in cached_read_tokens from repeated prompt prefix The caching makes the 10x difference look even bigger. First turn = 300k uncached. Subsequent turns = the prompt base (~200k total) but DeepSeek only charges for the delta (~25k uncached tokens, rest is cached). So the quota impact is: - Each reload costs you ~300k uncached tokens (one-time) - Each steady-state turn costs ~25-40k uncached (+ ~100k cached, which is cheaper) - Frequent reloads from the crash/fix cycle this session burned a lot The fix is straightforward: reduce what gets injected on the first turn (particularly `format_recent_turns()` limiting and session-packet size) and avoid unnecessary reloads. <matrix_lite_final>Good question. The 300k spike happens on the **first turn after a session reload**. Every other turn is ~25k because caching kicks in. **First turn after reload (300k uncached):** - Session-packet injected in full (continuity, curated memory, decisions, notices, recent topics — very verbose) - Room-local conversation tail reconstructed from message history (up to 50 turns) - Character card, heartbeat, full turn-packet - ACPX backend starts fresh with nothing retained, so everything comes from injected context - No prompt cache benefit yet **Steady-state (25k billing):** - Only the turn-packet is injected per turn (already smaller) - ACPX retains history natively - DeepSeek's prompt caching covers the repeated prefix (~98k cached tokens), so you're billed only for the delta The 10x difference is mostly the session-packet + room-local tail hitting fresh. Every reload this session cost you 300k uncached tokens. Reducing first-turn bloat (especially the session-packet and `format_recent_turns` cap) would help stretch your quota.</matrix_lite_final>


Hmm, that changes things. If the session has been running since yesterday (since the last reload at ~21:19Z May 20), and you saw 300k on turn 2-5 from now, then it can't be the "first turn after reload" explanation. The session was at ~120k when it reloaded yesterday, ran up to about 294k total by last check, and steadily accumulates conversation history each turn. The 300k spike you saw a few turns ago lines up with a specific pattern: the `format_recent_turns()` function reconstructs the last ~50 room-local exchanges, each up to 2400 chars (1200 user + 1200 assistant). With several turns of verbose conversation (like our session where I keep apologizing and explaining), that quickly adds up to the 200-300k range per turn. The direct cause: `PACKET_RECENT_MESSAGES=50` which means each turn rebuilds the last 50 user/assistant pairs into the prompt via the "Recent room-local conversation" section. Every turn this grows because it always takes the last 50. When our exchanges are verbose (like this troubleshooting session), 50 turns of ~2000 chars each = ~100k chars = ~25k tokens *from the room-local tail alone*. Add the growing turn-packet and ACPX history and you hit 300k easily. The simplest fix: change `MATRIX_LITE_PACKET_RECENT_MESSAGES` from 50 to maybe 5, and reduce `TURN_PACKET_RECENT_MESSAGES` from 4 to 2. These are env vars, so we can test them without touching daemon.py. <matrix_lite_final>You're right, that contradicts the first-turn theory. With this session lasting since yesterday and having many verbose turns, the 300k spike is from the **room-local conversation tail** in `format_recent_turns()`. It reconstructs the last 50 user/assistant exchanges each turn. With verbose exchanges (like this entire troubleshooting session where each message is paragraphs long), 50 turns × ~2000 chars each = 100k chars = ~25k tokens just from that section. Plus the growing turn-packet with "Current thread" dumps, plus ACPX's own retained history, and you're at 300k. The env var `MATRIX_LITE_PACKET_RECENT_MESSAGES` controls this. It's set to 50. Dropping it to 5 and `MATRIX_LITE_TURN_PACKET_RECENT_MESSAGES` from 4 to 2 would cut the per-turn bloat significantly without losing useful context. Want me to set those?</matrix_lite_final>

Great idea. Let me check if we can target a different model for the subagent. <matrix_lite_final>Yes, this workflow is possible. I can write the review/implementation request, then spawn a subagent with a different model to review it while I investigate the evidence in parallel. The `matrix_lite_status_subagent_spawn` tool has a `model` parameter. The question is whether GPT-5.5 is actually available through our provider. The topic-chat profile uses GPT-5.4, so 5.5 might work. We can test it. Here's the plan: 1. I write the prompt bloat analysis + implementation request to a file 2. Spawn a subagent with `model="github-copilot/gpt-5.5"` (or whatever the right ID is) to review it 3. The subagent reports findings back to this session Want me to draft the document and try the spawn?</matrix_lite_final>

If the session has been running since yesterday (since the last reload at ~21:19Z May 20), and you saw 300k on turn 2-5 from now, then it can't be the "first turn after reload" explanation. The session was at ~120k when it reloaded yesterday, ran up to about 294k total by last check, and steadily accumulates conversation history each turn. The 300k spike you saw a few turns ago lines up with a specific pattern: the `format_recent_turns()` function reconstructs the la… - Recent actionable/status notes: - [assistant] <｜｜DSML｜｜tool_calls> <｜｜DSML｜｜invoke name="read"> <｜｜DSML｜｜parameter name="filePath" string="true">/home/matrix-lite/app/scripts/persistent-chat-memory</｜｜DSML｜｜parameter> <｜｜DSML｜｜parameter name="limit" string="false… - [user] Turn metadata: - room_id: !CZLwoJfCyftA7oA5CVj2gIEKWqyv1lu01r0oFboEqZg - source_event_id: $J8dGidfpm5PtopAJFI-vPoDET46w2ZKSe-WBcORXd2Q Memory/continuity: Persistent-chat memory/continuity context: mode: turn_packet # … - [user] Turn metadata: - room_id: !CZLwoJfCyftA7oA5CVj2gIEKWqyv1lu01r0oFboEqZg - source_event_id: $N1W3CRbqrUDa3MNgGOWu2v0b-fiIaRp8mSj4kxwwXVI Memory/continuity: Persistent-chat memory/continuity context: mode: turn_packet # … - [user] Turn metadata: - room_id: !CZLwoJfCyftA7oA5CVj2gIEKWqyv1lu01r0oFboEqZg - source_event_id: $kxaa3dX9S62rR36GHbB6zrgz3A7bkcHspsJJ9vLiJeY Memory/continuity: Persistent-chat memory/continuity context: mode: turn_packet # … - [user] Turn metadata: - room_id: !CZLwoJfCyftA7oA5CVj2gIEKWqyv1lu01r0oFboEqZg - source_event_id: $ZYup9GCVsiiAqsWslukWNbQwCIkTZH-NOV2bg5nSpME Memory/continuity: Persistent-chat memory/continuity context: mode: turn_packet # … Recent room-local conversation: User: Yes this is great. However this doesn't explain why I sometimes see insane input metrics. Like last turn was 25k which is a lot but you are investing the daemon too and the turns are bloated as you described. However the turn before that was 300k which is definitely not intended. Why does it jump like that? I'm trying to stretch my nanogpt weekly quota here Assistant: Good question. The 300k spike happens on the **first turn after a session reload**. Every other turn is ~25k because caching kicks in. **First turn after reload (300k uncached):** - Session-packet injected in full (continuity, curated memory, decisions, notices, recent topics — very verbose) - Room-local conversation tail reconstructed from message history (up to 50 turns) - Character card, heartbeat, full turn-packet - ACPX backend starts fresh with nothing retained, so everything comes from injected context - No prompt cache benefit yet **Steady-state (25k billing):** - Only the turn-packet is injected per turn (already smaller) - ACPX retains history natively - DeepSeek's prompt caching covers the repeated prefix (~98k cached tokens), so you're billed only for the delta The 10x difference is mostly the session-packet + room-local tail hitting fresh. Every reload this session cost you 300k uncached tokens. Reducing first-turn bloat (especially the session-packet and `format_recent_turns` cap) would help stretch your quota. User: The session is going since yesterday and I've seen these numbers 2-5 turns ago Assistant: You're right, that contradicts the first-turn theory. With this session lasting since yesterday and having many verbose turns, the 300k spike is from the **room-local conversation tail** in `format_recent_turns()`. It reconstructs the last 50 user/assistant exchanges each turn. With verbose exchanges (like this entire troubleshooting session where each message is paragraphs long), 50 turns × ~2000 chars each = 100k chars = ~25k tokens just from that section. Plus the growing turn-packet with "Current thread" dumps, plus ACPX's own retained history, and you're at 300k. The env var `MATRIX_LITE_PACKET_RECENT_MESSAGES` controls this. It's set to 50. Dropping it to 5 and `MATRIX_LITE_TURN_PACKET_RECENT_MESSAGES` from 4 to 2 would cut the per-turn bloat significantly without losing useful context. Want me to set those? User: I think we need a deeper investigation, please write a review/implementation request. Actually how about you write the request and use a gpt 5.5 subagent to review it while investigating the evidence? Is it possible currently or is something missing for this workflow? Assistant: Yes, this workflow is possible. I can write the review/implementation request, then spawn a subagent with a different model to review it while I investigate the evidence in parallel. The `matrix_lite_status_subagent_spawn` tool has a `model` parameter. The question is whether GPT-5.5 is actually available through our provider. The topic-chat profile uses GPT-5.4, so 5.5 might work. We can test it. Here's the plan: 1. I write the prompt bloat analysis + implementation request to a file 2. Spawn a subagent with `model="github-copilot/gpt-5.5"` (or whatever the right ID is) to review it 3. The subagent reports findings back to this session Want me to draft the document and try the spawn?

Subagent `72f3f07fe30e` **failed** — same timeout pattern at 300s. **What happened:** The subagent started, connected, and began working ("Reviewing the request document first, then I'll spot-check the referenced code paths..."), but the very first tool call was `read` with empty input `{}` (no file path specified), which hung. Then it hit `session/request_permission (running)` — a pending permission approval that was never answered, causing the full timeout. **Observable pattern:** Three subagents in a row have now failed similarly: - `6b42b8344955` — succeeded (simple smoke test) - `f3f946d63fe4` — timed out after `ls` worked (stalled on tool confusion + permission) - `72f3f07fe30e` — timed out on first `read` with empty input + pending permission The subagent environment doesn't have interactive permission approval available, so any task that triggers an `ask` permission rule will stall indefinitely. This matches the known issue from the logs (pending approvals for `rm`, `date -u`, etc. that never get resolved). If you need the review/spot-check work done, it'll work better if I run it directly here in the main session rather than via subagent — I have full tool access and won't hit the permission-approval dead end.
