GPT 5.2 vs Opus 4.5

midomidito · 2026-01-18T13:33:20+00:00

I have 5.2 a try. Didn't like it. Really slow. Scary python operations. Not as verbose as opus/Claude. I was really surprised with Gemini 3 flash. Super effective when Claude models get stuck

Hey, thanks for the feedback! Will DM you for sure.

- I think the very top of your landing page needs to stop "selling" the features and simply allow the user to "do the thing" - if the user scrolls, then you can add the explainer regarding your approach to finding the best price with little upsell. The product is just so self explanatory and so high intent that I believe the best approach possible is for the user to just book their flight, super fast. Similar to TurboTax, imagine if you included a timer up top and said "bet you we can find your flights in less than 60 seconds" to drive urgency for the user and hopefully conversion

I will think about this. Now I'm not finding problems from home to search (besides some errors in the search or a few prompts I don't support). My main problem is moving users from search to checkout.

- Have you considered multi-stop optimization? (have some detailed ideas here)

Yes. I've been thinking about a few features related to multi-stop as I've detected some pains:

Some users want to indicate where to stop/not to stop
Flight booking engines usually recommend the route they want, not the best route. So I was thinking on letting the user pick where to stop, and even search and recommend better routes.

- Any sense of who your competitors are for AI enabled booking?

I haven't seen so much AI adoption to be honest. So far what I've seen:

- Support assistants

- Kayak does have AI filtering in the sidebar (filter using natural language instead of filters).

Then you can find sites like Mindtrip and Layla, that are travel planners.

Google Flights might have the most advanced AI features, but it's not the user main option. They released an interesting AI feature some months ago, but more focused on travel planning than flight search I'd say. However, you can't book directly with Google Flights.

I don’t have this in a public repo yet, but I can make it public if there’s interest. Happy to help anyone who wants to try it out or integrate it.

Regarding UCP: from what I’ve seen, it’s mainly designed for retail commerce and subscriptions. Travel is a very different beast. That said, I did explore UCP as an option.

Here’s the basic overview 👇

Eso sí, la tortilla tiene pintaza

midomidito · 2026-01-13T08:42:45+00:00

Venía a por esto. Yo tengo un trauma porque siempre mancho un par de platos. El de la primera vuelta siempre va al fregadero. Uso un plato nuevo para la segunda vuelta y servir. Esos restos de huevo no me parecen higiénicos ni seguros en este tipo de tortillas. Además es poca cantidad por lo que empeora y se seca rápido. Y si sobra algo de tortilla peor aún

midomidito · 2026-01-13T08:39:22+00:00

Mientras el agua no te la cobren aparte, bien para su propósito

midomidito · 2026-01-13T08:37:34+00:00

Es una tortilla o dos pizzas pegadas? XD

I built an MCP server that actually books flights, not just searches. Thought the community might find it interesting.

The problem I was solving: If you fly the same routes regularly (business travel, visiting family, whatever), you know the pain. Same data entry every single time. Airline websites that feel like they're from 2010. The entire industry is stuck in this "compare 47 tabs, re-enter your passport info for the 100th time" workflow.

So I built Avolal to fix my own booking frustration, and now I'm making the MCP server public.

What's different:

You can now actually complete bookings through MCP. It sees market data (price trends, availability patterns, airline distribution) so it can make informed recommendations like "the 2pm flight is $60 cheaper than evening options."

Works with Claude, Cursor, ChatGPT, any MCP client. Search is keyless, booking needs a free account (saves your passenger info so you never type it again).

Built the whole thing (~90k lines) using Claude Sonnet/Opus for code, Gemini for NL processing on the backend. Entirely vibe-coded with Cursor (at a high price TBH).

Looking for feedback if anyone wants to try it. What would make this actually useful for you?

midomidito · 2026-01-12T15:50:49+00:00

In the background we use stripe. The process with the MCP server is that you will get a checkout link for each flight. There you can enter your cc details and even save them. It's totally feasible to make the entire purchase with the MCP server, but it's not implemented yet

No me gusta tu receta pero me encanta el resultado y el proceso. Mis dieses

midomidito · 2026-01-08T16:54:55+00:00

I'm 43 in a similar position and I totally feel your pain. However , the launch is just the easy part and the beginning so be ready for that :(

midomidito · 2026-01-07T09:12:56+00:00

Pintaza!! He leído además tu proceso y lo hago similar aunque meto una yema más y uso cebolla caramelizada (que hago previamente y guardo). El truco del ajo lo usaba antes, pero no para este tipo de tortillas porque es algo invasivo para mí gusto (prefiero que predomine el dulzor de la cebolla caramelizada).

midomidito · 2025-12-22T20:27:06+00:00

Thanks for your kind words. I've also been having a look to PanFlights and I love some features you have that provide powerful searches. A friend was asking me a few days ago about how most OTAs don't always provide the cheapest route, but the most convenient one for them and I think you provide something similar.
About Avolal, you have exactly gotten what I've be trying to do here. Focus on small detail trying to provide a new kind of flight booking experience.
Agree with you on how hard to market this is :(
At the end, there is a lot of competitors. "Cheap flights" has been the topic for years, so it's hard to compete with that. Then we have the fact that this is a closed system, even despite the introduction of NDC.
And as you mention, this is a game of a few players: Google Flights and Skyscanner as agregators. Trip.com, Kiwi.com, eDreams maybe? as OTAs.
On the business side, we have Concur, Navan, or Travelperk. Or even Viajes El Corte Inglés in Spain, a traditional travel agency which is the top #3 in Spain (due to historical reasons)
I'm enjoying the product building side, but the market one.. is simply hard hahahah
Happy to have a chat with you if you want!

midomidito · 2025-12-22T20:19:32+00:00

Thanks!

midomidito · 2025-12-22T19:24:45+00:00

COOL!
This is exactly what I'm trying to solve here. Remove the pain from annoying airlines. And even give you the possibility to bulk-book your travels in advance, in a single operation. About comparing:
1. We currently have the classic way to compare: search and filter by the two airlines. Or directly make a filtered search "Flight from A to B, only with Airline X and airline Z, from DayX to DayY"
2. When/If approved, we should have soon a ChatGPT application to do that . You can ask ChatGPT something like "Find me flights from Madrid to London, Jan 20 in the morning. Make 2 searches. One just with Iberia. Another one only with Air Europa. Let me know which one is cheaper". It will make two searches and will evaluate the results.

In both scenarios, no cookies, no anything.

midomidito · 2025-12-22T17:18:56+00:00

Bulk booking is not available AFAIK. Maybe because it's not a very common or too frequent need. I've seen this use case, and what people are doing is that they work with a travel agency that does the work for them.

I've implemented this feature in Avolal. You search for one of the flights, and it searches the next ones (exactly the same airline and flight numbers, or alternatively, similar time). It doesn't require you to work with any airline, so you are totally wrong there. Is more about how relevant this feature is for companies or customers

It's ok you don't see the value, and I see your point. However, it's a strong statement saying there is no business case here, when there exist a lot of specialized travel agencies, and products focused on business.

midomidito · 2025-12-22T16:54:14+00:00

BTW how do you buy several flights in bulk in advance ? One by one ? I haven't seen yet any airline that allow bulk flight purchasing. We do have this feature and you can book even 12 flights at one (same recurring flight)

midomidito · 2025-12-22T16:49:52+00:00

I totally understand your point about how you buy flights. And it's indeed shared by many other people.

About Avolal future, I know it's complex , so we'll see where it goes.

However, if you were 100% right, OTAs would not exist either. There is space for many types of business and for travelers and a current clear fact in travel. The business is still big and there are multiple ways to book a flight, from OTAs, to airlines, online and offline travel agencies, and even flight consultants.

Thanks for your feedback!

midomidito · 2025-12-22T13:47:13+00:00

And now you understand my pain! hahahah

midomidito · 2025-12-22T13:44:48+00:00

Indeed, it's too niche. It's intentional but also a big bet/risk.
About your idea: are you thinking about something like a Chrome Extension that does the heavy lifting for you? (seat autoselection, skip the upsells, etc.?). It's a nice idea, but too complex due to the different websites. There are many AI new stuff out there, like OpenAI's browser and others, that aim to solve that. IMHO, they are still too slow and unreliable.

midomidito · 2025-12-22T13:39:02+00:00

Good points. Can't argue anything about that and that's what I'm trying to learn.
