I dont understand why there is not a gpt-6 terra?

It wasn't really used enough and it sat in an awkward middle space between luna and sol where either luna high/xhigh or sol med were better cost/perf wise

I don't agree. In "none" thinking mode, Terra serves a useful purpose where medium-grade intelligence is needed. Luna doesn't cut it.

Hardly enough time had passed to develop the data to come to a conclusion. Users can take time to build interest.

It probably didn't see that much use, as it struggled to find a niche. If you wanted intelligence tasks, Sol was cheap enough and much smarter. If you wanted performance and cost-effectiveness, Luna was significantly better value while being only a little less intelligent.

Terra ended up just being an awkward middle ground that was not particularly suited for any workload.

I disagree. After a bit of experimenting, I actually found Terra to be a very good workhorse model on none-to-medium reasoning, and I actually quite prefer its code to Sol's in many cases. It has less of a complexity to over-complicate things. Where Sol would have a sea of try/except and recoveries for situations that are structurally impossible, Terra would just write nice, sequential code.

Maybe for one-shotting large things Sol is better, but for prod code where I decompose into smaller tasks and read all the code I favored Terra.

Sol 5.6 was still king for architecture/research in my workflow, though.

The users of Terra disagree. Specifically, Terra is useful when medium-grade intelligence is needed in instant ("none" thinking) mode.

Hardly enough time had passed to develop the data to come to a conclusion. Users can take time to develop an interest.

Well, naturally people who use it are doing so because they like it. But I'm sure OpenAI is looking at the relative value/usage of Terra next to the other tiers.

I have found it worked quite well as the workhorse model in my hermes agent.

I'm scared now, my employer only allows Luna and Terra on 5.6. I really hope they will allow Sol then on GPT 6.

Funny thing is they very recently also set a real limit per-user/month, so why even limit the models because theyre "too expensive".

Your employer should reconsider. Sol high is cheaper than Terra max and smarter, when measured per task. ie even if tokens are more expensive Sol can often do a job with fewer tokens.

I read that there are rumors that they're getting rid of that tier. No idea where the rumor came from, though. This lends credence to it, I suppose.

Sol price is halved so no need for terra

This is all just running in circles. The models are not obviously better. The pricing fluctuates or offset by some other less-obvious metrics (availability/speed/tokens per task/dumbing down). Everyone reports different outcomes in their usage because it's all so context and user dependent. Sometimes models do some things better but become so annoying and obtuse in their other doings that it's just not worth it (like Opus with the insane code comments and Astra with its over-the-top, everything-is-a-sales-pitch style). It feels like the AI gods just turn the knobs on things like compute to get the results they want to align with the IPO to make headlines.

Anthropic it is game over when they passed OpenAI at the beginning of the year.

Now it is revenge time and OpenAI kind of is trolling Anthropic by simply going into a price war with impressive performance.

OpenAI is doing a decent job this year after they recovered. Anthropic needs to offer more payment options and be clear about token usage. The warnings I got when switching to Fable 5.1 felt like a thread. I bet more and more on OpenAI since I don’t feel robbed by them.

To me it's super interesting that OpenAI released GPT-6 Sol and Luna & Anthropic released Opus 5.5 within hours of each other.

These models are significantly cutting down the token costs by almost 40-50% as compared to their predecessors. This is exactly what people need - cutting edge intelligence at half the cost.

I've been running 2 threads of Opus 5.5 for ~16 hours on a server C++ to Rust translation/optimization project and used 8% of the 20x sub. Going to test out gpt6 sol over the weekend, but it really seems like we're back in the realm of having to try to burn a 20x sub.

Wow. Luna 6 is an insane value bargain at this point. If Anthropic doesn't finally come out with their own small low cost model instead of still having haiku 4.5 they'll be history soon.

I'm trying to test them but the Visual Studio Codex Extension on WSL2 is not helping.

It seems there's a bug, shipped together with the flag that enables the new models, that doesn't allow Codex to run properly in the WSL2 sandbox.

Why not use Codex CLI from inside WSL2? That’s that I do. I have Ubuntu LTS and while the VS Code extension works fine (for the most part) the CLI is where it’s at. The same goes for CC.

Interesting that factual error rates have not improved a lot since the last year. Models are getting smarter but not more trustworthy. At this point I would love to have a model that's maybe not as smart but has lower factual inaccuracies and works harder. I.e don't try to find shortcuts as much and does more rigorous self checks.

Live notification in Codex:

> GPT-5.6-Sol is retiring. This conversation will automatically switch to GPT-6-Sol

I don't recall OAI retiring a model so early lol. Similar arch?

It looks like the optimal pattern is to have Astra as the orchestrator and Sol as the implementer. Same as with Fable and Opus.
petesergeant 2 days ago||
I've found Astra to be horrible at making orchestration decisions. I will be trying to use Sol for both. Fable is very good at it though. Worst part of my week is when I hit my Fable usage limit and have to switch to Astra.
afro88 2 days ago||
I've found Sol to be an excellent orchestrator, with Astra the planner and Sol again the implementer.
cesarvarela 2 days ago||
I'll try that since I'm on the 100 plan and they disabled the 200 one.

The hard part for me is choosing the model and effort, that's why I always resort to Astra xhigh, but then it ends up consuming tokens so fast.

How do you decide what to pick? I mean, I do Platform work on a large monorepo with many different interconnected services, and so I always want the implementation to be "correct".

Depends on the complexity of the task. And how fast I want it solved. If I wanted solved fast I use a better model (Sol), If I can afford some time I use Terra (I use terra for most coding things). If it is something super simple like changing a css class I use Luna.

Simple as it sounds but I ask Sol or Astra to propose optimal model and effort level for a given workload. Works pretty neat for me.
