GREENAIBOX advertises up to $25,000 in GPU Cloud or cluster credits for pre-seed and seed companies, with up to $100,000 for Series A training workloads.

The official Azure student page's separate Azure for Startups comparison advertises $1,000 instantly without an application and up to $5,000 total after business verification.

The collected official pricing page reconfirms $100 in one-time usage credits on E2B Hobby without a credit card. Hobby supports sandbox sessions up to one hour and up to 20 concurrent sandboxes; the free plan label does not mean unlimited free compute.

E2B Hobby now documents 10 concurrent sandboxes alongside $100 credits
The collected official E2B pricing reference retains $100 in one-time Hobby usage credits without a card but now documents up to 10 concurrent sandboxes, versus 20 in the master record. Sessions remain limited to one hour; sandbox CPU and RAM are usage-billed, so the $0 monthly plan fee does not mean unlimited free compute.

RunPod referral reward requires both users to spend $10 before receiving credits
RunPod's official guide says referring and referred users receive a randomized $5–$500 credit only after both parties have spent $10. This materially corrects the known signup-bonus description: it is a conditional referral reward, not free compute immediately on registration.
Value
Random $5–$500 referral credit after each party spends $10
Who qualifies

LangSmith Developer now describes Fleet inclusion in LSUs rather than 50 runs
LangSmith's collected pricing retains the $0 one-seat Developer plan and 5,000 base traces per month, but describes Fleet as metered in LSUs with 7 LSU included rather than the master's 50-run allowance. The comparison also lists one free Serverless (Small) deployment; additional deployments and usage are metered, so this is not unlimited free hosting.
Value
$0/seat Developer plan; 5K base traces/month; Fleet includes 7 LSU; one free Serverless (Small) deployment listed
Who qualifies
Solo users getting started on the one-seat Developer plan; paid usage applies beyond included allowances
