RooCode + Gemini Flash 2.5 doesn't really let me down much for coding. Usually takes just a bit more requests and every now and then needing to look up a module that's not working to find a working version (looking at you moviepy >.>). Orchestrator mode also doesn't work well with flash 2.5 from my tests. Although recently I've just been using it more so as a tool in automated scripts. It makes as a very powerful summarizing tool + report generator. Much more thorough reports than its older 2.0 flash model. Answer from Dundell on reddit.com

r/ChatGPTCoding on Reddit: Which APIs do you use for FREE - Best free options for CODING
June 6, 2025 -

Hi Guys,

let's grow this thread.

Here we should accumulate all good and recommend options and the thread should serve as a reliable source for getting surprising good FREE API Options shown.

I'll start!:

I recommend using the Openrouter API Key with the unlimited and not rate limited Deepseek/Deepseek R1 0528 - free model.

It's intelligent, strong reasoning and it's good at coding but sometimes it sucks a bit.
I Roocode there is a High Reasoning mode maybe it makes things better.

In Windsurf you can use SWE-1 for free which is a good and reliable option for tool use and coding but it misses something apart from the big guns.

In TRAE you can get nearly unlimited access to Claude 4 Sonnet and other Highend Models for just 3$ a month! Thats my option right now.

And... there is a tool which can import your OpenAI-Session Cookie and can work as a local reverse proxy to make the requests from your Plus Subscription work as API request in your Coding IDE ..thats sick right?
