Originally created by @cvkmohan on GitHub (Jul 12, 2025).

Originally assigned to: @thdxr on GitHub.

I have been using opencode for the last 10 days or so. I can say - intensively. However, till yesterday, not once did I reach a stage where we get out of tokens/out of context window. Even with reasonably big operations - somehow opencode managed to run - most of the times - not even reaching 50% of token size. However, from yesterday - after upgrade to 0.2.3x or so - suddenly, the consumption increased very significantly. Every restart getting exhausted in minutes. In fact, with my claude MAX $200 subscription - never reached its limits. In less than an hour - dramatically I am told that my limit gets reset after 4 hours.
Has something changed? Or problem is at my end?
Raising an issue because - nothing much changed in the way I use - but - I see a dramatic increase in token consumption and context exhaustion.

Just wanted to alert. Close it, if it is not related.

can you reproduce a situation where the context window gets big faster than you expect a /share a link?

Thanks for the quick response. I will share if it happens. So, no change on that front in code? One difference I can think of is the FigmaMCP that I used. Maybe its output is doing some mischief. Earlier with my Elixir Code - it never crossed 20% - including contexts, tests etc.

I can confirm that token usage/context window usage has dramatically increased. I tried to run the same task in both claude cli and opencode cli - and opencode cli exhausted context window by the time claude cli reached 50%. Earlier it used to be reverse. Something changed.
Neither to hurry you nor cribbing. Just wanted to share the information. Please do not mind.

i looked through your session (if you open browser console in share page it prints out an object with everything)

i don't immediately notice anything suspicious - you can see in each step-finish part it report how many tokens it wrote into the cache

it progressively gets bigger - not sure

Facing the same issue. Burnt through around 800K tokens for just a few edits. Is there any way to remove the diagnostics and start from a clean slate?

But, this is not a newly introduced feature. I was dealing with a bigger project (same in elixir, phoenix and liveview) a week before this issue - and - opencode was handling the context beautifully. I mean, it reached a maximum of 50% even with a long conversation. Something changed for sure.

@thdxr @adamdotdevin I'm noticing this also with GitHub Copilot as a provider in particular, across various projects seeing the token limit being hit after a few messages. I think it's probably related to diagnostic messages as I'm debugging some large error logs in both cases

in 0.3.16 i filter out only Error diagnostics. we might remove them all together for project level ones but this is a first step

I wanted to add that I’m also seeing extremely high input token usage on a relatively small SvelteKit project, even after adding an AGENTS.md file that excludes node_modules, .svelte-kit/, and build/ folders.

Since last night, I’ve already burned through $20 in usage, which is far beyond what I expected for this project.

Here’s the exact error I’m now encountering on each prompt:

[!ERROR]
{
  "data": {
    "message": "AI_APICallError: input length and max_tokens exceed context limit: 172775 + 32000 > 200000, decrease input length or max_tokens and try again"
  },
  "name": "UnknownError"
}

I also pulled my Claude usage logs and saw input token counts regularly in the 160k–172k range, all within minutes:

2025-07-20 14:29:30 — 172,448 tokens
2025-07-20 14:29:25 — 172,242 tokens
2025-07-20 14:29:15 — 171,931 tokens
...

I’ve tried compacting the session and deleting recent messages, but I’m now completely blocked due to the context limit being exceeded on every request. As a result, I am unable to do anything.

I’d be happy to share my session log privately if that helps with debugging

@claidler commented on GitHub (Jul 20, 2025):

Yeah it's worth me stating that one of mine was particularly small also which is why I imagined it may be diagnostics related. I'm wondering if there are restrictions around reading very large files or very large logs. Mine had 3-4 normal files, but some large files after a build that may have been picked up, or some long logs.

@claidler commented on GitHub (Jul 21, 2025):

Reviewing with AI, it said that there are not per file context limitations - I wonder if there should be. If someone has a large pdf or text file that they need to commit in their project that keeps getting picked up, this would be a point of frustration. I understand not everyone would want this, so it might need to be configurable, but I think we could decide on a sensible default considering any good code project shouldn't have code files longer than a certain amount of lines.
Is there anything in place here, and if not, could we put something in place?

This is the issue for me as well, just a simple prompt skyrockets the token usage. Would be nice to see what files / additional info was sent.

Yes, there is something wrong... plain message costs 45k+ tokens... e.g. Kimi K2 is not able work... and is possible somewhere set model provider for OpenRouter?

@thdxr I think in v0.9.5 the token count is incorrect:

But when I open the shared session, it's showing 252 tokens: https://opencode.ai/s/Whzi8BH0

MCP-s cost a lot of tokens! I enabled just a few. Figma, jetbrains, and it eats up 52k (20%) tokens!!

Figma use A LOT. I always keep it disabled and enable if I need. This is Claude Code, not OpenCode, but you can see context content there.
