Agent-Hopping - A Cost-Effective Way to Access Coding Agents

You probably don't need >$100 plans for coding or toying with OpenClaw. My thoughts below.

Note: Due to the mindbreaking speed this agent universe is moving at, this may be out of date within 2 days. (Last verified on 2026-04-19)

What Changed Since Feb 2026 #

• Qwen Code: OAuth free tier was discontinued (2026-04-15). Use Alibaba Cloud Coding Plan, OpenRouter, Fireworks, or BYO API key instead.
• Claude: Opus 4.7 released and replaces 4.6 as top tier. Anthropic calls this a step-change for agentic coding.
• Amp: Amp Free admissions are still closed “for now” for new users. Existing free users may continue receiving grants (which became ad-free).
• Copilot: Premium usage now follows request-based billing semantics. Plan allowances differ, and model choice can change request burn rate via multipliers. Also, Copilot Free is an excellent baseline budget option for autocomplete.
• OpenCode: Provider-agnostic CLI tool. Note: OpenCode documentation mentions support for ChatGPT Plus via OAuth, though verify OpenAI's current policies on third-party integrations.

The Case for Agent-Hopping #

Agents are blowing up. Loss-leading platforms and pricing models are emerging. Everyone wants a slice of the intelligence pie. $200 subs are no longer the only way to continually access coding agents anymore. If you have the tolerance to handle switching agents now and then, you can have a whole lot of quota to play around with and ship meaningless products with.

I guess we need a r/ChurningLLMs soon.

Most ICs are becoming AI agent managers instead, and a good manager would not stick to one employee, especially with no switching costs involved. This article is more intended towards the educational benefits of "trying around" to see what works, and how to optimize quotas based on the level of intelligence needed.

Intelligence Tiers #

We can tier the availability of intelligence and think of it as a "runway - cost matrix":

• SS tier (frontier): Claude Opus 4.7, GPT-5.x coding variants, and Gemini 3.1 Pro-class models.
• S/A tiers: Sonnet-class and top open-weight coder models for lower-cost long sessions. Model ranking changes quickly; verify current release docs before committing to one-stack workflows.
• B tier (great for regular work, agents): Gemini 3.0 Flash, GPT 5 mini (59.8% score at $0.04/task - insane value), Claude Haiku -> Great for boilerplate work.
• C tier (awesome for running OpenClaw and longer agents without racking up API costs): DeepSeek V3.2 via API ($0.28/1M tokens input, $0.42/1M tokens output - 95% cheaper than GPT 5). The sweet spot for long agent sessions that make hundreds of calls.
• D tier (Sorry r/localllama): GPT OSS 120b, Devstral 2.1 Small, Qwen3-Coder-Next, Codestral. SOTA models for running locally, great if you know what you're doing. Not so great compared to money makers. In other news, water is wet.

Strategy: Monthly Subs > API Costs #

There's no comparison. Most companies are losing money on people who use monthly subs properly. If you are maxing out your context window every hour and forcing the routing to the largest models, they are eating compute costs.

The single-plan approach:

• One Claude 5x/Max or Gemini AI Ultra or GPT Plus plan
• Pros: No interruptions, no focus loss, continuous coding
• Cons:
  • Vendor lock-in, suboptimal pricing especially with so much competition and alternatives.
  • You don't get to try the latest and best models as these guys take turns releasing.
  • Each model has a smell / strength - Gemini is great for UI, Claude is great at most types of coding, ChatGPT is the best reviewer and long context.

Best Value Patterns Right Now #

1. The Multi-Sub Stack (Recommended Default) #

• Primary: $20-ish IDE/chat plan for convenience (e.g., Claude Pro, Cursor, Windsurf).
• Secondary: $10–$20 backup plan to avoid rate-limit stalls.
• Paygo: Route heavy autonomous tasks through BYOK routers (OpenCode, OpenRouter) using price-first routing (:floor).

2. Single Max-Tier (Only if Provably High Utilization) #

• Use a single $100+ max plan only if your observed weekly usage repeatedly saturates two or more mid-tier stacks. Otherwise, the multi-stack approach gives better resilience to model swings.

3. Task-Class Routing Policy #

• High-risk refactors / architecture: Frontier tier (Opus 4.7, GPT-5.3).
• Boilerplate / lint / tests: Cheaper or included models.
• Long agent loops: Paygo model routing with explicit max-price controls.

ChatGPT Plus is a strong candidate depending on current limits/model access:

• Offers codex agent.
• Offers gpt-5.3-codex-high, head-to-head with Opus 4.7 for the best coding model today.
• Has high limits, but verify current constraints as they are dynamic.

Notable Tools & Subscriptions #

Get a base sub (~$20/mo) as primary, then layer on free trials and cheap options. Here's what I rotate through:

Claude Code - Claude Pro ($20/month) #

• Claude is much more straightforward and Claude Code is probably the best CLI tool available today, all things considered.
• Claude Sonnet 4.6 (Model of Choice) - use this for primary work where speed and accuracy are important.
• Claude Opus 4.7 - for tasks that need more brain. Anthropic calls this a step-change for agentic coding.
• Cons: Limits are dynamic and usage-policy driven.

Google AI Pro (Free Trial) #

• Use this to try Antigravity IDE, which is another great option. It's a modded VSCode fork where agents get their own dedicated surface with direct access to the editor, terminal and browser - agents can autonomously plan and execute complex tasks simultaneously.
• Gemini 3.1 Pro Models - one of Big 3. Just dropped Feb 19 with leading scores on 13 of 16 benchmarks.
• Also supports Claude Opus/Sonnet and GPT-OSS-120B (low limits) as well.
• Also opens up Gemini CLI (not as good, use Antigravity directly)
• Cons: Too many 429's

Github Copilot ($10/month) #

• I've used this for the longest time.
• They used to have 300 premium requests - 1 interaction/session counted as a request.
• Now every message (small "hi" or "implement the world") counts against the same request - so it's easy to hit the limit if you're chatty.
• But using their <1x models, especially Grok Code Fast 1, is a great fallback.
• Built in with VSCode

ChatGPT (Go Plan) #

• Promotional usage limits available in Codex till March 2nd

Amp (by Sourcegraph) #

• Update (Feb 10, 2026): Amp Free is currently full for new users while they work on their next version.
• Normally provides a $10 free daily grant that replenishes hourly (~$300/month of free credits). That's a lot of Opus 4.6 for free.
• Available in terminal, VS Code, Cursor, Windsurf, JetBrains, and Neovim.
• Funded by ads from dev/infra companies (Axiom, Baseten, PlanetScale, Prisma, Tailwind Labs, etc). Basically, you see a banner and get frontier models for free.
• Can delegate complex coding tasks, refactors, reviews, and explorations to agents that work across entire codebases.

Kilo Code #

• Open-source AI coding agent for VS Code, JetBrains, and CLI. Forked from Cline/Roo Code, raised $8M seed, 1.5M+ users, #1 on OpenRouter.
• Free with bring-your-own API key, or Kilo Pass credits starting at $19/month with zero markup on model costs.
• Access to 500+ AI models at provider rates. The Orchestrator mode breaks complex tasks into coordinated subtasks across planner, coder, and debugger agents - pretty neat.
• Contains a bunch of free models, and the ones being secretly tested.

OpenCode #

• Open-source CLI coding agent, like Claude Code but provider-agnostic. Go-based TUI with LSP support, multi-session handling, 75+ LLM providers via Models.dev.
• Pipe in any OpenRouter model - unified API gateway with automatic fallback, rate limit handling, and cost tracking. Pay-as-you-go, pick your own model.
• OpenAI openly supports OpenCode via Codex OAuth, so you can use your ChatGPT sub directly.

Local options

• Qwen3-Coder-Next (your first "usable" <60GB coding model), GPT-OSS-120B (matches o4-mini on coding benchmarks), Devstral, Kimi-Dev-72B, Codestral

Qwen Code #

• Open-source CLI coding agent by Alibaba/QwenLM, purpose-built for Qwen3-Coder. Claude Code-like terminal experience with Skills, SubAgents, and multi-session handling.
• 1,000 free requests/day via Qwen OAuth - just sign in with your qwen.ai account, no credit card.
• Qwen Code (updated): Qwen OAuth free tier was discontinued (2026-04-15). Use Alibaba Cloud Coding Plan, OpenRouter, Fireworks, or BYO API key instead.
• Supports OpenAI, Anthropic, and Gemini-compatible APIs. Point it at any provider or run it entirely local via llama.cpp - it speaks the same OpenAI-compatible protocol that llama-server exposes.
• The framework and the Qwen3-Coder model are co-developed and released together, so it gets first-class support for new model quirks.
• Worth pairing with your D-tier local setup: Qwen3-Coder-Next on llama-server + Qwen Code on top = a fully offline coding agent at zero recurring cost.

Free options worth considering #

• Google AI Pro free trial (includes Antigravity)
• Zed Editor - 14-day trial with $20 of introductory tokens
• ChatGPT Codex - temporarily free
• Cursor - 14-day Pro trial (normally $20/mo)
• Amp - $10 free daily grant (currently full for new users)

A Note on TOS #

By no means does this promote trial hacking or the like. Don't try to break TOS, like using OAuth proxies for using Claude / Gemini for other services like OpenClaw - bans are in full effect (except OpenAI, which openly supports using OpenCode via Codex OAuth - yay Sam!?!?)

Try a few, find what sticks, rotate when limits hit. That's the whole strategy.
