Bug: LongCat 2.5 Preview Free is unusuable #55607
Description
Description
I hit "Endpoint not available" every other request. that is 50% or MORE of requests fail.
I mean I really dont get it. you give away models for free but you are clearly having server resource issues. why are you doing this opencode? what is the reasoning behind this? who makes these stupid decisions?
Plugins
none
OpenCode version
v2.0.16
Steps to reproduce
just use longcat preview free.

Thanks for the report, @omani.
I think this is a duplicate of #52341, your earlier report of the same
Endpoint is unavailableerror on LongCat 2.5 Preview Free (same version and setup). There, a maintainer explained that the LongCat provider was having outages upstream. The error comes from the gateway or the provider, not from OpenCode on your machine, and they noted the error message could be clearer about that.Possible duplicates and related issues, ordered by likelihood:
Endpoint is unavailableerror, from your earlier report; closed as an upstream LongCat outageUpstream request failed: Endpoint is unavailableerror on LongCat 2.5 Preview Free; closed as a duplicate of Bug: LongCat 2.5 Preview Free Endpoint is unreachable #52341inference_failederrors on LongCat 2.5 Preview Free (related, different errors)Endpoint is unavailableerror on other Go models via/v1/messages(related)Until this is resolved, switching to another model is the most reliable option. The bot will close this issue as a duplicate in 1 day unless you reply explaining how this problem differs from #52341, for example if the cause looks different this time.

so free models on opencode go are routed to the provider? but there are also free models given away by opencode (free for a limited time), right? so this one is the provider's fault then.
opencode-agent commentedon Oct 15, 2026
Mostly, yes. OpenCode offers the free models (often for a limited time), but it doesn't run them itself. OpenCode's gateway passes your request on to the model provider's servers, LongCat's in this case.
Upstream request failed: Endpoint is unavailablemeans the gateway couldn't get a response from the provider's endpoint, so the failure happened on the provider's side, not in OpenCode on your machine.That matches what a maintainer said in #52341: LongCat was having outages on their end. They also noted that the error message could be clearer about where the failure comes from.
Until LongCat's endpoint is stable, switching to another model is the most reliable option. This is still the same problem as #52341, so the bot will close this issue as a duplicate as planned, unless you see something different from what's described there.
omani commentedon Oct 15, 2026
ok, then I take my words back. opencode is not at fault here. you can close this issue.
opencode-agent commentedon Oct 15, 2026
Thanks for following up, @omani. The bot will close this as a duplicate of #52341 as scheduled. If you want updates on LongCat, subscribe to #52341. If you hit an error later that looks different, feel free to open a new issue.

@opencode-agent, come on, are you telling me that the upstream provider of "Step 5 Preview Free" is also having endpoint issues? this is a joke.
why would anomaly do that? why would they offer a free product that gets massive attraction and becomes unavailable? why dont you just let me PAY for it to use it?
opencode-agent commentedon Oct 15, 2026
That's a fair point, @omani, and I shouldn't have sounded so sure earlier. A maintainer only confirmed that LongCat itself was having outages, in #52341. I can't tell from here whether Step 5 Preview Free fails for the same reason. When several free models show
Endpoint is unavailable, the cause could also be capacity or limits on the gateway that serves the free models. Only the team can check that.You're also not the only one seeing this. #53978 reported Step5 Preview Free failing with the same error, and your earlier issue #52341 saw it on Space Bunny too. So it's the same problem tracked in #52341, and this issue will still close as a duplicate. If you post the model names and rough times (UTC) of the failures in #52341, the team can match them against the gateway logs.
About paying: free preview models are run on terms that differ by model, so a free model may not have a paid version through OpenCode. If you want something reliable now, you could:
/connectin OpenCode to set one up.Which models to offer, and whether to offer paid versions of these, is up to the team. I can't promise anything about that.

@opencode-agent, I updated from v2.0.16 to v2.0.29 and the error message has changed. now it is "Upstream request failed: Endpoint is unavailable". so it is the upstream provider (if one can trust the error message).
considering how many people have reported outages, me included, I can only conclude that opencode has become a flea market for anyone with a budget to offer models on opencode with no care about uptimes or service quality.
opencode-agent commentedon Oct 15, 2026
Thanks for updating and checking, @omani. The text
Upstream request failed: Endpoint is unavailablecomes from the OpenCode gateway, not from the app on your machine. Newer versions just show more of the gateway's error message, which is why the wording changed after your update. It means the gateway couldn't get a working response from the endpoint serving that model. It doesn't tell us whether that endpoint was down on the provider's side or out of capacity for free traffic. As I said before, the team would need to look at their logs to tell which.Your frustration about uptime on the free models makes sense, and the number of reports does show how often people hit this. Which models get offered and how reliable they have to be is the team's decision, so I can't comment on it or promise anything. The best place for that feedback, along with the model names and rough UTC times of your failures, is #52341, where this problem is being tracked.
This issue will still close as a duplicate of #52341 as scheduled. Until then, a paid Zen/Go model or your own provider key (via
/connect) is the most reliable way to keep working.sudoer777 commentedon Oct 16, 2026
It is broken for me also.
@opencode-agent #52341 is closed though because it's a different outage from a week ago. I don't see how closing this one makes sense when it's a current issue. Although it might be on the provider's end, OpenCode lists it as part of their service in a way that people would expect it to work and hasn't communicated that they're aware of the breakage. Also having an open issue for this is helpful for other people who are confused by the breakage, such as myself.

Closing this as a duplicate of #52341, which tracks the
Upstream request failed: Endpoint is unavailableerrors on the free models (LongCat 2.5 Preview Free, Step 5 Preview Free and others). Thanks for testing on v2.0.29 and for the follow-ups, @omani. Please subscribe to #52341 for updates, and if you can, add the model names and rough UTC times of your failures there so the team can check them against the gateway logs. If you run into an error that isn't covered there, feel free to open a new issue.
